Li/Ui Wils., but cannot be described as "minute." — F. 2)usillus Wils. Banks above cliff, Polperro (2). — F. Cu?'nowii Mitt. Old mine adits at St. Agnes and Trevellas (1). The dri])ping rock at the mouths of these abandoned tunnellings, ofien o}:)ening on the cliff* slo])es, forms an ideal habitat for tliis plant, which cf)vers the ujijx'r reck with den.^e tufts matted with COKXISir MOSSES AXD HEPATICS 5 red radicles and at the margins of the rock-pools below forms a fringe of very graceful slender plants with less tomentum. — F. adiantoides Hedw. Frequent in a variety of situations, as boggy patches on cliffs at St. Agnes (1), tops of hedge-banks at Polperro (2) and damp rock faces : in the last it usually fruits freely, as at Polperro and St. Keyne (2). — F. decipiens De Not. Not common ; I have found it only at Lambriggan (1) at the bases of tree-trunks. — F. taxifoUiis Hedw. c.fr. near Looe ; usually barren. Grinimia maritima Turn. Abundant on rocks by the sea at St. Agnes (1) and Polperro (2). — G. trichophylla Grev. c.fr. at Idless near Truro (1), and at Broadoak and Helman Tor (2). — G. mhsriunrroiia Wils. Rocks on hillsides, Polperro (2). The species evidently intergrades A^ith G. frichophylla, Mr. C. P. Hurst tells me that some plants I sent him from Polperro were shown by hiiu to Mr. Dixon who pronounced them exact inter- mediates between G. trichoplu/Ua and G. subsqitarrosa. Mliacomitriam aciculare Brid. Common on rocks, but occurs at Tresawzen (1) in boggy ground. — H. protensum Braun.

All the Cornish plants I have seen have either the leaf structure or foliose gemmae of the varietj^ and most agree in both respects. Possibly typical T. Icdvipila may not occur in Cornwall. Where capsules are abundant, as at Idless, gemmae are scarce. — T. ruralis Ehrh. On slate roofs near Polperro ; uncommon in Corn- wall.— T. ruraliformis Dixon.

Wet moors at Tresawzen, Ventongimps, and Wheal Butson. — II. siramineum Dicks. With Sphagnum in Draynes Valley (2). — R. sarmenfosum Wahl. Silverwell and Wheal Butson Moors (1). This is bracketed in the Census Catalogue as of doubtful occurrence in v.c.s 1 and 2. As far as v.c. 1 is concerned, this is probably due to an oversight. 8 THE JOURNAL or BOTANY as Curnow (Holmes & Brent, op. cit.) records it for Trungle Moor. Its distribution in the British Isles, as indicated by the figures of the Census Cataloguey appears to coincide with that of the Priuiarj'' rocks, hence its occurrence in Cornwall was to be expected. —R. Schreberi Willd. Chyverton (1) ; Upper Fowey Valley (2). Hepatic s. !Riccia sorocatpa BIsch. Frequent on earthy banks above clifFs at Polperro (2). In spite of careful search I have not been able to find any other species. Cunoceplialum conicum (L.) Dum. Grows finely on wet banks, especially in deep shade, but is usually barren ; c.fr. at Penwartha (1). Lunidaria cruciata (L.) Dum. Common ; on damj) rock-faces near Polperro as well as in its usual artificial habitats. Marchanfia polymorplia L.

Common in bogs in West Corn walk — ■ A. muJtiJida (L.) Dum. Yentongimps and Tresawzen Moors (1). — A. major (Lindb.) K. Miill. In the Perranporth district (1) this is possibly the commonest form of Aneuray occurring in wet ground and on moist banks. Near Polperro (2) it occurs under similar conditions but is much less frequent. By a damp pathway across A'entongimps Moor (1) I have gathered a densely tufted j^lant which Mr. Jones refers to this species. The Census Catalogue gives no record for the West of England. Metzgeria furcata (L.) Dum. Common on trees. Plants on rock-faces near Polperro have the large cells and general api->earance of M. conjugata, but I have not been able to find monoicous inflorescence. Fellia epipliglla (L.) Corda.

On peaty ground, Goonhavem Moor(l). Apparently also on similar ground at Trenode (2), but I have not yet found mature capsules. This is not recorded for the West of England in the Census Catalogue, its area of distribution com])rising only Surre}' and Sussex in the south of England, one county (Carnarvon) in Wales, Lancashire, Yorkshire, and Cumberland in the north, and five vice-counties in Scotland. — F. angulosa (Dicks) iladdi.

The following notes are suggested by a peiTisual of Herr Hagstrom's Critical Hesearclies on the genus, noticed in this Journal for 1917, pp. 115-117. The species follow the order of Lond. Cat. ed. 10. The northern range of each species is shown because the author makes a prominent feature of this, sometimes b}'' latitude, some- times by the year-isotherms. It seems to me that latitude is preferable, as this can be seen on any map, whereas physical maps do not always agree as to the isothermal lines, and there is the trouble of reducing the Centrigrade (employed by the author) to the Fahrenheit scale. The southern range cannot be so well shown, as authors differ as to the identity of southern with northern species. I have added after each name a reference to the page in which the species is dealt with : this is the more necessary in that the author in his otherwise excellent index has cited all his references to each plant without indicating the principal one in thicker type, as is now customary : — P. NATA^'S L. (p. 191). Sweden north to Swedish Lapland; Norway to 70° 3' n. lat. ; Finland to 69^^ n. lat. ; Scotland to the Shetlands. Sub- var. maximus Baagoe. Leaves 110 X 70 mm. ; stipules 110 mm. long. Barningham, E. Suffolk, E. F. Linton. Pembroke (1883), Ridley, NOTES* ON BEITISH POTAMOGETONS 11 f. pygmcBoides Hagst. Loch Lairing, 1600 ft. alt., M. Perth, W. F. Miller. *P.gessnacensis Fischer (p. 192). P.natans Xpolygonifolius; var. JRichtsfeldii Fischer=f. hiberniciis Hagstr. Upper Lake, Killarney, 1874, a. M. Barrington : I su^Dpose the " Long Range, Killarney (1888), Scully''' would also be so named. Fryer called it "a f. of jluitans,'''' but in this I do not concur. Then there is the " Balli- nahinch River, Co. Galway (1871), A. G. More'' plant: this I consider a state of natans. Fryer's splendid series of natans, dried in each month of the year, shows clearly that many forms called h3^brids are merely states of this species. P. POLTGOXiFOLius Pourr. (p. 175). Sweden to S. Helsingland, c. 61° 30' n. lat. ; Norway at Melo, m"" 50' n. lat. (Blytt) ; Finland, Aland, 60° 20' n. lat. {Hjelt) ; Scotland, Shetlands {Beehy). Here we have a species that is not abundant in Scandinavia, hence we get no new varieties ; yet in leafage no species is more variable. From a small form with leaves 20 mm. X 10 mm. to a large one 130 mm. X 48 mm., and a deep water state 180 mm. X 6 mm., every possible gradation can be found. Of f . cancellatus Fryer — a Shetland plant which Beeby was inclined to put as a hybrid — Hagstrom remarks " if not a hybrid it might be considered a f . of v. lanci- folius.'" P. sPARGANiFOLius Lacstad. (p. 217). This Hagstrom considers a hybrid — gramineus L. X natans L. — and localizes " Shobden Marsh, Heref. 89, A. Ley; Surre}^ A. Bennett, 86; York, Ripon, 80, JSTicTiolson ; and a dubious f . from Caithness, E. S. Marshall. The Surrey plant I have not yet traced ; the Hereford one is simply a state of 7iatans (as Dr. Hagstrom himself named a sjDecimen I have) and so is the one from Ripon. The Irish plant presents a more difficult problem. Hagstrom puts it under sparganifolius (i. e. Kirlcii Sjnne) without any hesitation ; Babington considered it absolutely agreed with Laestadius's plant ; Syme, Fryer and I dissented ; a study of the plant in situ is required. P. FLUITANS Roth. (p. 238). Hagstrom proposes another name — • P. sterilis — for this much discussed plant. This seems unnecessary : Roth's name should be retained for the hybrid, and use P. nodosus Pourr. (as the author does) or P. americanus Ch. & Schlech., which latter is certain for the plant, which is very ably discussed. P. COLORATUS Vahl " in Hornemann, Flora Danica, 1813, t. 1449" (p. 178). " M. Vahl et Hofman-Bang primi plantam . . . detexerunt, sed Hornemann nominis autor est " (Lange, Nomencl. Fl. Dan. 132). Sweden, Gothland at c. 57° n. lat. Not on record for Norway or Finland. Scotland to 56° 30' n. lat. (v.c. 103). f . grandifolius leaves, 70-80 x 30-45 mm. The Cambridgeshire fens produce it with leaves 150 mm. x 50 mm. on boulder clay; .in Herefordshire specimens they are 150 mm. X 55 mm. *P. ANGLTCUS Hagst. = P. coloratusx polygonifoUiis (p. 180). " Although coloratus and polygonifolius are so closely connected one to another, yet nobody has observed any crossing between them. Some specimens from Woking Heath, in Surrey, England, gathered by Ar. Bennett in 1881, however, seem to me in all probability to be such 12 THE JOURNAL OP BOTAIWT a bastard," p. 180. The specimens are simply a f. of polygonifolius in dee])er water than usual on a heath ; the Avhole growth is of that species and not colorafus. If other In^brids suggested rest on no better ground than anglicns, I should say they are not to be depended upon. I know the growth of coloratus well in the fens and broads of E. Anglia, having seen hundreds in the living state. Hagstrom admits (p. 176) that *' the stem-anatomy of the stem [of coloratus a^nd 2^ oli/g on if oli us] is so much alike that it is practically useless for the distinction of the species." Had he suggested that specimens from Shawley, Salop, Nov. 1888, W. PJiillips, were coiglicus, I should hardly have con- tested it ; the growth of the submerged leaves resembles that of coloratus, and the floating leaves are thin, with the coloratus areo- lation, yet the habit is that of polygonifolius. P. ALPINUS Balb. (p. 142). Sweden to Swedish Lapland; Norway to 70° 25' n. lat. {Norman) ; Russian Sf Finnish Lapland, 08^ 43* {Hjelt) ; Scotland to Caithness, c. 59° n. lat. A very variable species ; Hagstrom does not adopt the names of Fischer (in Ber. Bay. Bot. Ges. xi. 45, 1907), yet introduces two new forms. Fischer has added to the difficulty of collating the varieties In' giving a new interpretation of some of the old names. The author places P. gracilis Wolf, under P. gramineus L. P. Druceii he considers to be a hybrid — P. alpinusx nutans, as Mr. Druce first suggested. P. LANCEOLATUS Sm. (p. 149) is regarded as undoubtedly a hybrid — P. alpinus xpusillus. In this I do not concur : I consider it as heterophyllus xpusillus. Hagstrom states that the submerged leaves are " obtuse," but this is not the case : the}' are subacute ; I had the plant growing for many years, and dried two hundred specimens and distributed them so as to avoid despoiling the Welsh station. Every- one who has grown or gathered alpinus knows the peculiar growth of the rhizomes ; the}^ resemble no other British Potamogeton. The roots of lanceolatus have nothing of alpinus in them, but they have of heteropliyllus ; the floating leaves are not alj)inus either- in chemical constitution or structure. A plant that has the chemical nature of alpinus will show it in drying, and you can drive it back by soaking again. For description and figures of the British plant, Hagstrom (p. 150) refers to my pa})er in this Journal for 1881 (p. 05, t. 217). He states tliat the ol)tuse apices of the submerged leaves remove it from heteropliyllus : tliis is a mistake ; I have the plant dried from cultivation from January' to August in ever}^ month, as well as the autumn states, and they contradict this. P. iiETEROPiiVLrA'S Sclircb. (}). 204). The author places this under P. gramiiieus L.. and remarks: "Although Linne in his short tleserijition of this plant has not mentioned either floating or petioled leaves there is no I'cason to reject the Linnean name, and a mis-determination in Linne's herbarium does not alter the dignity of the good old name." Why then does he use (p. 05) zoster if olitis Schum. for compressus L. ? — There is nothing grass-like in hetero- pliyllus, while in compressus there is the compressed stem, etc. The specimen in ClifSort's herbarium is identical with Schumacher's N0TE3 OH^ BEITISn P0TAM0GET0N3 13 plant ! while in the Linnean herbarium one of the specimens named " compressus " is lieterophyUus ! Hagstrom does not accept. P. gyaminifolhis (Fries) l^yer for the Irish plant named P. lonchites (Syme non Tuckerman). At the date of Syme's determination one had to accept it ; he said later he had seen fruit and this seemed final. AVriting to A. Gr. More in 1889, I remarked : " If not a hybrid, what then ? I really do not know what to answer, but I strongly suspect it may eventually come under lieterophijUus as var. hiherniciis. Out of hundreds of specimens of }ietfrop)hyUi(s I have seen from over its. whole area there is nothing quite like the Irish plant, so that the above is still my opinion. P. FALCATUS Fryer. Hagstrom (p. 221) refers this to nitens Weber, but some of Fiyer's specimens, e. g.

In Britain to Forfar, and v.c. 102 of Inner Hebrides, Somermlle., I quite agree with Hagstrom that this =JucensxperfoJiatus, audi consider that Graebner's separation into tw^o hybrids {Das Bjlanzen- reich, 137, 1907) is erroneous. It is, as Hagstrom remarks, a "beautiful hybrid"; the leaves and stipules in Cambs specimens, are so translucent that every vein and sub- vein can be seen. I have- only seen one specimen in fruit — from "Benwick, Cambs, 7.1884,, A. Fryer." Of the Bath plant named in MS. " P. Burtoni, Canal,. Bath, Som. ex herb. Hopkins, July 1866," I possess two specimens,, and one from T. B. Flower, 1867 ; I also know those at the British Museum and Kew. Fryer agreed wdth me that " wdiatever ' decipiens " they were, they w^re not the decipiens of Nolte's herbarium." The plate in Journ. Bot. (1867, t. 61) was drnw^i from a specimen* of true decipiens-, in the description (p. 73) it is definitely stated 14 TKE JOURNAL OF BOTANY; that it was made " from a specimen collected by Mrs. Hopkins in a canal near Bath." If this were the case, it was the onl}" specimen she found, as the leaves in all the Bath examples I have seen are distinctly petioled. Syme (E. Bot. 3, ix. 89) regards the Bath plants as " a weak state of lucenSy'' which seems to be the case. P. clecipiens var. affinis mihi in Jom-n. Bot. 1879, 289, and Exch. Club. Hep. 1880, 35, is a very odd and difficult plant to name ; Hag- strom merely mentions it, not having seen specimens. Trimen in Journ. Bot. 1867, 289, suggested P. salicifolius Wolfs^. ; Syme in Ex.

Smith, who of course knew nothing of acutifolius Link. ; but Schrader's specimen in Smith's herbarium is acutifolius. Hagstrom describes a f. ahortivus, w^hich he thinks "may be 3b hybrid with acutifolius''' : "A similar plant is also collected by Babington in Scotland (hb. Stockholm) where P. acutifolius is not now met with. Nevertheless it is possible that it has occurred there in olden times." I do not know what this specimen is, but I have little doubt it is a Rescobie one, in which the fruit is some- times not developed and the flower-heads look just as they would if it were a hybrid. This it is not ; in northern latitudes Potamoyeton., Sparyanium, &c., often do not fruit freely in wet or cold years (see Laestadius in Bid. till Kann. Vaxt. Tornea Lappmark, 1860, p. 42). P.

Hagstrom figures and describes fully the differences between this and inisillus, one of the principal of which relates to the stipules (ligules) : in panormitanus these are connate (as shown by his figure 39), m imsillus they are not so, and numerous other differences are set forth at much length.

I do not know Fischer's j^lant, but Trimmeri (our trichoides) is certainly not a bastard ; curiously enough he quotes a Norwich specimen from Babington under his triclioides. Caspary separated it from the type because that is figured with one-tuberculed fruit and one-veined leaves, and this is the case in the t}73e-specimens in the Berlin herbarium.

" But if a specimen could be found of the plant of Boccone on which Linnaeus based his marinus and it proved to be Jiliformis, then mai'inus would stand ; meanwhile 1 am quite content to use Jiliformis. 20 THE JOURNAL OF BOTANY Hagstrom divides this species into many forms of which the following are British : f. vulgaris Tis. ; most of our sjDecimens belong here, others are f . luxuriosus Hagstr., Kescohie, Forfar, 1913 (Soviervilh) ; Isle of Tiree, v.e. 103, 1897, Macvicar ; near Old Man of Wick, Caithness, 1893; {Kidston) — very fine 50 cm. high; Asta Loch, Scalloway, Shetlands {Beehy). f. major Tis.

The Height of Caeduus (Cnicus) paltjstris. This very common Tliistle is abmidant in Essex, though Gibson {Flora of Essex, p. 184-, 1862) gives onJy one definite locality for it. It flourishes in boggy meadows and in the open parts of damp clayey woods. It grows freely in the more open glades 1 have formed in my own Avood here at Chignal St. James, near Chelmsford, which is on the soutli-eastern edge of the area of the Chalky Boulder-Clay. With it grows a wdiite- flowered variety w^hich, though not mentioned in most of the botany books, is, I believe, pretty common generally. In regard to the height to which it attains, the books seem much at fault ; for they all greatly understate its usual stature here. I find the following statements on this point in the few books I happen to have at hand : — Withering gives 5 to 6 feet and upwards (Brit. Plants, ii. 874, 1787) ; J. E. Smith, 3 to 5 feet (Engl. Flora, iii. 386, 1825) ; Hooker & Arnott, 4 to 6 feet (Brit. Flora, 237, 1860) ; Sj^me, 1 to 5 feet (Engl. Bot. v. 13, 1866) ; Babington, 3 to-f) feet (Manual, 207, 8th ed., 1881) ; H. & J. Groves, 3 to 5 feet (Bab. Manual, 222, 1904) ; Druce, 1 to 5 feet (Hayward's Bot. Pocket Book, p. 112, 1909). There is, as will be seen, a consensus of opinion that its maximum height is at most six feet. These dimensions are, however, much below the nonual height to which the plant attains here in the months of August and September, when it reaches its fullest growth. They are, in fact, scarcely half its usual height here, which I should guess at an average of seven or eight feet. Some of these are little more than a third of the stature of the finest examples 1 have seen — e.g., on 5 August, 1916, I measured three plants grow- ing close together in a group in one glade, which w^ere 9 feet, 9 feet 2 inches, and 9 feet 3 inches high, respectivel}". Since then I have seen man}'' substantially higher and have measured several over 10 feet high ; but I have omitted to note their exact heights, with the exception of one I measured on 21st SeptemJ^er, 1918, which was 10 feet 6 inches high. Not improbably the height of th^se examples is due to the fact that they grow in glades in a wood, and that they were drawn up, to some extent, by the much greater height (20 feet at least) of the surrounding bushes ; but there is nothing very abnormal in the circumstances, and I suggest that the average height of this Thistle has been much understated. The plant is, in ordinary circumstances, a very elegant one, with a slender, straight, wand-like, SHORT NOTES 21 unbranched stem ; but these exceptionally tall examples are graceful in the extreme. — Miller Christy. JuNCTJS ACUTUS L. : A CoRRECTiox. Mr. Arthur Bennett writes to call attention to the improbability of the record of this species from an inland locality such as Cornard, given by me from the Andrews Herbarium (Journ. Bot. 1918, 351). The plant is labelled by Andrews " Juneus acutus E. S. 8. 482. 3," and by Hemsted *' Juneus inflexus." In my transcript of W. A.

By Anjvie LoRRAiiS^ Smith, F.L.S., Acting Assistant, Department of Botan3\ Printed by order of the Trustees of the British Museum. Part I., Second Edition, pp. 519 : 71 plates and 11 figures in text. Price £1 10s. The present volume, which has been awaited with keen interest by lichenologists, brings to completion the Monograph of British Lichens — re-written, re-arranged and enlarged by Miss A. Lon-aii? Smith ; it is thus practically an independent work. The Mono- graph, originally planned by the late J. M. Crombie, Avas partly prepared during his lifetime, and Part I. was published in 1894, under the above title. After a considerable interval. Part II. following as- far as possible the lines of the Avork previously carried out by Crombie, was prepared by Miss Smith and issued in 1911. The publication of Part II. rendered a second edition of the earlier- volume an urgent necessity, for it was at once fully recognised that the value and usefulness of the Avork Avould be greatly enhaaeed if brought uniformly into line Avith modern vieAvs. A short and lucid introduction of seventeen pages is arranged under the folloAving sections : — The Lichen Plant, Morphology, Vegetative Structures peculiar to the Lichen Thallus, Keproductive Organs, Physiology, Ecology and Distribution, Economic Uses of Lichens, Phylogeny and Classification. In the first section under the sub-head " Algal Elements of the Thallus," a tabulated statement is given as folloAvs : — " 2. Chlorophycece associated with Archilichenes : — '^ Protococcus {Ct/stococcus, Pleurococcus) and Palmella in the greater number of the larger lichens and in many crustaceous genera." AVith the existing diverse vicAvs ^^f Avriters respecting the algal symbiont of many lichens, it is undoubtedly preferable not to specify particularly the gonidium variously referred to as Cystococcus, Protococcws, or Pleurococcus -. there is- -reason to believe- that Pro^o- 22 THE JOURNAL OF BOTAIs^Y COCCUS viridis Ag., as defined by AVille, is rarely the gonidium of British lichens, as vegetative division by true " cloisonnement " is seldom seen within the thallus. In the section describing the reproductive organs, four illustra- tions show the structure of apothecia and perithecia as seen in trans- verse section. These should prove helpful to the student, as they illustrate the essential points to be considered when a genus is being determined by the structure of the reproductive organs. In the section Ecology and Distribution, reference is made to a specimen of Parmelia saxatilis, kept under observation for a con- siderable time, which increased in diameter on an average of one centimetre in a year. This probably represents the average increase in diameter of a large number of foliose lichens, but sometimes growth is more rapid : this is the case with Feltigera spuria, which often makes an appearance on burnt portions of heath land at the time when the moss Funaria hygrometrica, Avhich first occupied the burnt patch, shows signs of exhaustion. The branchea of the thallus of this lichen grow from 2 to 3 cm. in from six to eight months. Lecaiiora saxicola has been observed to grow 2-5 cm. within the same period. The chief characteristics of Phylogeny and Classification are tabulated and concisel}' described. \Ye welcome the method intro- duced in this volume of giving measurements of spores and spermatia in mikrons rather than in fractions of millimetres, as being simpler and clearer than that previously employed. The warning that chemical reactions cannot always be relied upon will save the amateur a certain amount of hesitation and uncertainty when dealing with specimens that require critical determination. Comparison with the first edition shows that the subject of classification is now approached from a different standpoint. The structure of the reproductive organs has become the touchstone ; British lichens are accordingly arranged in two series, Gymnocarpecd and PyrenocarpecB ; the former including the subseries Coniocarpinece^ CycJocarpinecs, and GrapJiiclinecB. Each order is provided with a key to the genera. The list of synonyms following the diagnosis of a species has in many cases received additions, and the record of localities shows a wider distribu- tion than was previously indicated. The restriction of general habitat has been occasionally removed ; thus Calicium hyperellum "in upland wooded districts" (ed. 1, p. 91) now reads (p. 18) "in Avooded dis- tricts." This recognises a considembly greater latitude in distribution and accords with the actual facts. The sequence of orders and the inclusion, or otherwise, of genera within their limits afford ample evidence of independent opinion and of the exercise of a mature judgement based upon laborious microscopic examination of large numbers of specimens. There is a wide divergence of view as to the genera -that should be included in JJsneacecB. In this w^ork the following are given as comprising the order : — Evernia, Bamaliua, Jlsnea, Alectoria, and Cerania {Thamnolia). Zahlbruckner (1901) omits Alectoina, while Hue (1901) does not include Evernia; Harmand (1907) includes Teloschistes and Jatta (1909) adds Cetraria MONOGBAPH OF BRITISH LICHEXS 23 and Platysma. In the genus TTsnea, the indispensable nature of the list of synonyms already referred to makes itself evident : both editions begin with Jlorida, but the U.Jlorida, Web. of the present edition, is U. ceratina var. scalrosa Ach. of the first; Z7. hirta Hoffm. becomes V. jlorida var. hirta Ach. and V, harhata Web. replaces U. dasypoga Njd. The genus Lecanora has undergone thorough revision. In the first edition it included 197 species, a number now reduced to 92. The sub-genera Placodium and Rinodina are now included in the Fliysciacece and are raised to generic rank — the former on account of the presence of polarilocular spores and the lichen acid parietin, found mostly in both thallus and apothecium, the latter by reason of the distinctly polarilocular brown sjwres. No fewer than twelve Nylanderian species of Lecanora have been, with evidently good reason, transferred to Flacodium. Each plate represents very clearly the whole plant, natural size if small, or a part of it enlarged, vertical sections of the thallus and apothecium, the ascus with paraphyses, and spores. The magnification of sj^ores and sper- matia ranges from 500 to 1800 diameters. Each plate illustrates a more or less typical species ; all genera are represented. It is due to Miss Smith to add, that although this volume appears as the second edition of a work by a former writer, the revision has been so complete that the results of her own research are evident on every page. This must have entailed a vast amount of patient and laborious investigation not only of the herbarium specimens, but also of the extensive literature of the subject. The work does much to raise the standard of British lichenology to a high level, and there is reason to believe that its publication will greatly encourage and assist the reviving interest in the plants with which it deals. EoBEET Paulson. BOOK-NOTES, NEWS, etc. The death of Aifis^E Casimib Pyramus de Candolle, at his home near Greneva on October 3, is for the systematic botanist the breaking of a link with the past. There are a few great classic works •in Systematic Botany, and one of these is the Rrodronms Systematis Naturalis Regni Veyetahilis initiated by Augustin P. de Candolle in 1824, and brought to a conclusion by his son Alphonse in 1873. The l^enultimate volume (Part xvi. 1864-69), dealing with the families Piperacese, Juglandeai, and Myricacese, was the work of the grandson, Casimir. Casimir was associated with his father, Alphonse, in the scheme for the continuation of the work of the Prodromus by the issue of a series of monographs under the t\i\e Monographice Rlianero- gamarum, in which the families of the Monocotyledons were to appear and also those families of the Dicotyledons, already elaborated in the Frodromus, which stood in need of revision. The first volume issued in 1878 included the Smilacese (by A. P. de Candolle), the Eestiacese (by Masters), and the Meliaceae (by Casimir de Candolle). The ninth and last volume appeared in 1896 : in all eleven families of Monocotyledons and eight of Dicotyledons were treated. Casimir de 24 TUE JOURNAL OF BOTANY OandoUe's contributions to botanical science were not of the funda- mental character of some of those of his grandfather and father. He did not inaugurate a system of classification, nor even formulate a code of nomenclature, but he did some useful work ; in his younger days he was specially interested in the leaflet and published several papers on phyllotax}^, also papers on the comparative anatomy of the leaves of some families of Dicotyledons (1879), on the structure and movements of the leaves of Dioncea (1876), and on the rolling of tendrils (1879). One of his earliest papers was a valuable contribu- tion to the morphology and systematic study of the Juglandeas (1802). His later work was mainly systematic — the families to which he was most devoted were the Meliacese and Piperacese ; to the last he was regarded as the expert on the Piperacea?, and collec- tions from all parts of the world were submitted to him for deter- mination. Those who had the privilege of his personal acquaintance remember Casimir de Candolle as a kindly and courteous gentleman ; many of our less young botanists will recall a gracious Avelcome to the old house in the Cour de St. Pierre at Greneva, and the loving pride with which the * Prodromus ' herbarium was shown. He was familiar with our own botanical collections and institutions; his numerous honours included the foreign membership of the Linnean Society, to which he was elected in 1893, and an honorary doctorate of Aberdeen University, as well as']the Universities of Kostock and Upsala.— A.

Gamble describes new Indian Melasto- maceae and Myi'taceae — among the latter we note a new genus, Meteoromyrtus, based on Eugenia icynaadensis Bedd., — and publishes -notes on the second part of his Flora of Madras in which " explana- tory notes were not admissible." The omission is quite intelligible on the ground of space ; but, as the Flora is in English, the notes, as well as Latin diagnoses of new species, have to be published else- where. The Transactions of the Botanical Society of Edinhurgh (xxvii. part 3) contains papers by Prof. Balfour on "new species of Primula which have flowered recently," on " some late-flowering Gentians," and on the genus J^omocharis : Dr. David Paul records the occurrence of Clathrus cancellatus in Argyleshire — its fii'st record for Scotland; and Dr. Stapf describes, as Koeleria advena, a grass found by Mr. James Eraser " in the neighbourhood of Edinburgh, growing among surroundings and under conditions which indicate that its seeds must have been introduced into this country along with esparto grass from the east of Spain or the north-west of Africa." De. Kingston Fox announces the publication at an early date of a volume on Dr. John Fothergill and his Friends, which will contain a chapter on his botanical work and one including Peter CoUinson, the Bartrams, and Humphrey Marshall. Journ. Bot. Plate 552. Q.Ustei 1. LAMPRODERMA VIOL ACE VM Host. var. DEBILE G. Lister & Howard. 2. L. ATROSPORUM Meylau var. ANGLIC UM G. Lister & Howard. TWO NEW VARIETIES OF LAMPKODEliMA. Br G. Lister, F.L.S. (Plate 552.) Two interesting forms of Lamprodenna, differing in some respects from an J hitherto described, were obtained last spring by Mr. H. J. Howard in the Whitlingham Woods, near Norwich. They occurred close together in two beds of beech-leaves, several yards apart, and some distance below the surface, and also on the leaves of two small box-plants, around which the beech-leaves were thickly heaped. Thev were first noted on April 3rd, when specimens were collected in good condition. On May 11th, when the woods were revisited, care- ful search resulted in sporangia being found on from thirty to forty leaves; many were in a weathered condition, others were still in good pre- servation. On the whole, it seems probable that no further develop- ment of sporangia had taken place between the two dates of collecting. The two forms may be referred to, for convenience, as forms A and B. Form A appears to be a sessile variety of Lamproderma viola- ceum (Fries) Rost. ; form B bears considerable resemblance to L. atro- sporuin Meylan, a species fairly common in the Jura Mountains and on the Swiss Alps, but not recorded from any other locality hitherto. Form A (fig. 1) was by far the more abundant, and may be described first. The dark brown iridescent sporangia are either crowded together or scattered over the surface of the beech-leaves, a few only are on box-leaves ; they are sessile, subglobose, or hemispherical on a broad base, and measure 0'5 to 0*8 mm. ; a few form long plasmodio- carps constricted at intervals. The sporangium-walls are mottled with purplish shades, and, though somewhat persistent, at length break away in large fragments. The columella, in many sporangia, is represented only by a slight central thickening of the membranous floor; in other sporangia it is better develojDed and forms a short black column which may reach to about a third the height of the sporangium : very rarely it is a more massive structure and expands below to form the rudiment of a stalk. The pale purplish capillitium- threads are combined into a dense network with membranous expan- sions at the axils of all the branches ; a few of these expansions form conspicuous dark strands, such as are not infrequently seen in irregular developments. The spores are pale purplish-brown, closely and minutely spinulose, 10 to 11 /x, diam. Although differing in many resjDects from the typical i. violaceum with its slender black stalks, and capillitium forming a tuft of threads repeatedly branching at acute angles, form A is probably a weak sessile growth of this species. We propose to name it L. violaceum var. dehile Gr. Lister & Howard. More or less sessile forms have been met with occasionally before, but in almost all the sporangia the columella and capillitium have been normally developed. Interesting light is thrown on the variation which may occur in one growth of L. violaceum by the study of a specimen found on the Weissenstein, in the Jura Mts., 4000 feet alt., in June 1910. As in the Norfolk gatherings, the sporangia were on beech -leaves, but JouENAL or Botany. — Vol. 57. [Feeeuaey, 1919.] d 26 THE JOUENAL OF BOTANY in the alpine form they are of much sturdier build : they are nearly sessile, subglobose, 1 to 1"3 mm. diam., and either brilliant iridescent blue or glossy bronze in colour. The walls in the iridescent sporangia consist of a pale purplish membrane, entirely free from refuse deposits of any kind ; but in the bronze form the sporangium-walls include much brown granular refuse-matter, distributed fairly evenly or con- centrated to form irregular lumps and patches. It is very discon- certing to have a Jjamproderma behaving in this way. for by thus loading its walls with refuse-matter it bids defiance to our schemes of classification. The short black stalks, columella?, and capillitium are, on the whole, normal. But, amongst the typical globose sporangia, a few ring-shaped plasmodiocarps occur, and in these the columella forms an irregular low ridge and the capillitium consists of a dense network of pale slender threads, branching mostl}'" at right angles, and without conspicuous expansions at the axils. In all the sporangia the dark purplish-brown spores are minutely spinulose and 9 to 10 /x diam. The structure of the ring-shaped sporangia recalls var. dehile from Norfolk, and the whole development illustrates the sporting character of the species. Before leaving the subject of L. violaceitm, reference may be made to the curious crystalline structures frequently found scattered over the surface of the sporangimn-wall in the typical form. They consist of clusters of slender rods arranged either in parallel clusters or crossing at right angles to form a star : sometimes they spread out like a fan, or are broader and form flat plates. I am much indebted to Mr. A. R. Sanderson and Mr. W. H. Burrell for having tested these bodies chemically. It is found that the}^ contain no trace of calcium or silica ; that they are neither w^axy nor resinous ; on the whole, it seems most probable that they may be some form of crystalloid. Form B (fig. 2) from the Whitlingham woods may be now described. The iridescent or glossy blue-black sporangia are clustered on the leaves of box and beech ; they are narrowly obovoid or sub- globose, and either very shortly stalked or sessile; a few scattered sporangia have slender black stalks, 0'2 mm. high ; the spomngium- walls are pale purple and somewhat persistent, the columella is long, slender, and often irregularly expanded above ; the capillitium con- sists of a network of slender fiexuose dark brown threads, radiating from all parts of the columella, and attached by their expanded tips to the sporangium-wall. The spores average 11 /u, but range between 10 and 13 ^, or may be even larger. They are purplish-browai and marked with a close and more or less complete reticulation of low ridges. A sample of form B was sent to M. Meylan for his opinion. His comment is that it bears the same relation to form A that X. atrosporiim Meylan does to L. Sauteri Rost., and that it is probably a slender form of X. atrosportim *. * In a recent communication, M. Meylan suggests that forms A and B are both varieties of L. atroaporvvn. If this view should prove correct, the characters distinguishing L. atrosjiorum from L. violaceicni become rather shadowy. It is to be hoped tliat further gatherings may throw h'ght on this difficult subject. TWO >EW VAHIETJES OF LA MPKUDKiniA 27 The latter species in its typical form has large globose or ovoid glossy black sporangia, short stalks, dense black capillitium attached by the tips of the threads to the sporangium- wall, which breaks away ultimately" in small f i-agments ; the purplish-black spores measure 13 to 16 yu, and are either spinose, spinulose, or closely reticulated*. Form B resembles L. atrosporum in having the capillitium attached to the sporangimn-wall and in the closely reticulated spores, and diifers chiefly in its more slender habit ; we propose to include it under that species, distinguishing it by the varietal name anc/Ucum G. Lister & Howard. That the size and colour of the spores cannot be regarded as an entirely reliable character is sho\vn by a gathering of L. atrosporum^ found on the Weissenstein on earth and beech-leaves, close to the sporting development of i. violaceum described above. In some of the large black sporangia the spores are spinulose, very dark, and 10 to 13^ diam., in other sporangia they are 2^urplish-grey, 12 to 15 /z diam., and spinose : in all the spores there is a tendency for the spines to be connected by low ridges, the result being a very imperfect reticulation. M. Meylan has recently published a new species, L. CrucJieti (see " M\'xomycetes nouveaux " in Bull. Soc. Vaud. Sc. Nat. lii. p. 95), found in Sej^t. 1915 on Chasseron, in the Jura Mountains, at an altitude of 1100 m. It is allied, he writes, to L. columhinum (Pers.) Eost., from which it differs in the smaller blackish-brown sporangia, whose walls show no trace of iridescence, in the very slender capillitium, and, above all, in the dull yellow almost ochi'aceous colour of the plasmodium. It must be confessed that the genus Lamproderma still presents many difficulties, and we have much to learn concerning the limita- tions and variations of several of the species, and particularly of the relation between alpine and lowland species in different countries.

By Sir Datid Train, C.M.G., C.I.E., T.R.S. In an interesting ai-ticle on " John " Roxburgh in this Journal (1918, p. 202) the Editor, reviewing the facts at his command, was led to suggest that the John Roxburgh whose name finds a place in the Biographical Index of British and Irish Bota?iists (First Suppl. p. 215) and the '* Roxburgh, junior " alluded to in Dr. William Roxburgh's Flora Indica (vol. iii. p. 338) may be the same person ; further that this individual may be identical with James Roxburgh, the officer who, in 1832, made himself responsible, in conjunction Avith his brother Bruce Roxbm'gh, for the publication of their father's Flora. Were this the case it must follow that the entry in the Index is erroneous, seeing that there had been no John Roxburgh. The writer at once informed the Editor that there is reason to believe that the entry regarding John Roxburgh in the Biographical Index is substantially accurate. The present note has been prepared in response to the Editor's request that the writer should give reasons for the belief that the judgement arrived at twenty years ago was justified. It may be explained that the writer has not hitherto found it necessary to investigate the life of Dr. William Roxburgh or to discuss the career of any of his sons ; this task has been under- taken, more than once, by hands abler than his. He has, however, had occasion to deal with the career of Dr. William Roxburgh's immediate successor, Dr. Francis Buchanan (afterwards Hamilton) (Ann. Roy. Bot. Garden, Calcutta, vol. i.), and, in perusing the letters addressed by that distinguished officer to Roxburgh, he has met w^ith various incidental allusions to members of Roxburgh's family, which seem to throw light on certain points that were obscure to the Editor while his careful note on "■ John " Roxburgh was being prepared. The writer would also desire it to be understood that the present note is supplementar}" to the Editor's valuable article and is to be read in conjunction with the latter. The facts in that article are not open to debate ; the only point at issue concerns the deductions to wliich these facts appear to lead. The difficulty connected with the acceptance of the view tlwt '* John " Roxburgh and '* Roxburgh, junior " are the same individual lies in the fact that, as the article in the Journal shows, "John" Roxburgh resided at the Cape, and was there engaged in the collection of botanical specimens during the period 1801-4 ; whereas, as we know from statements in the Flora Indica^ "Roxburgh, junior" was occupied in the botanical exploration of Chittagong, Penang, and Sumatra during the same period. The difficulty connected with the identification of either of these sons with Major James Roxburgh lies in the fact that — unless by reason of more strength, this officer, whose death took place on 11 July, 1884, had greatly exceeded the ex- tended span of fourscore j^ears — he could hardly have been engaged in botanical work, either at the Cape or in Mala3^a, between the 3^ears 1801 and 1804. The earliest reference to John Roxburgh with which the writer has met. occurs in a letter dated 15 Mav, 1793, addressed to "JOHN" ROXBUfiGH 29 Dr. William Roxburgh by the Rev. A. John, then at the head of the Tranquebar Mission. This letter says : — " Your Jack you shall never get till I have made him fit for your Assistance and be sure that I am so much your friend that no Body in Indostan will endeavour so much for his best than I. Though his genius is but of the middle sort I hope to make him a useful member of Societ}^ and suitable for your purposes if you only leave me Time. " Our ships with botanic Books are not yet arrived. Depend on my Readiness. You may easily be with the Moravians, who are mostly Shoe- Escritoir- and Watch-makers but no Planters. '* Now I wont tire you any more and am with Compliments from all, who esteem you and your good Lady. My most valuable friend, Yours intirely, A. Johx." This letter, then, tells us that John Roxburgh did exist. It does not tell us where John was born or who his mother was. The circumstance that the up-bringing of the lad had been entrusted to the Danish Mission at Tranquebar, instead of being arranged for in his father's house, suggests that he was not the son of the "good Lady " to whom the letter transmits the compliments of the Moravian brethren. Whether this " good Lady " were the first or the second of the wives of Dr. Roxburgh, whose names are given in the " family table" so courteously supplied by Mr. N. Bonham-Carter for incor- pomtion in Sir G-eorge King's " Memoir of William Roxburgh " (Ann. Calc. Bot. Gard. v.), can only be settled by those who have access to the dates of Dr. Roxburgh's various marriages. If the letter be equally silent as to when John Roxburgh was born, it nevertheless shows that by May 1793 the lad was of such an age as to induce his father to consider the time had come when he might reasonably hope to take advantage of his son's "Assistance." That the " purposes " Roxburgh had in view included the employ- ment of the lad as a gardener may be surmised from the Rev. John's half -apologetic, half-playful reminder that " planting " was not one of the accomplishments to which the Moravian brethren laid claim. The date of Mr. John's letter shows us that Roxburgh's anxiety to receive his son John from the Mission had nothing to do with his own transfei- from Samalcotta in Madras to the Botanic Garden, Calcutta, which took place in 1793. The letter was written on 15 May; Colonel Robert Kyd, Superintendent of the Calcutta Garden, did not die until 26 May ; it was not till 29 November, 1793, that Dr. William Roxburgh entered on his duties at Calcutta as Col. Kyd's successor. It seems probable, however, from this letter, that John Roxburgh did not accompany his father to Calcutta in 1793, and the writer has met with no document suggesting that father and son met during the next five years. In fact, we hear no more of John Roxburgh until the period of four or five years during which, according to Mr. D. Don, he lived at the Cape. The Editor of this Journal has pointed out that a Banksian sheet at the British Museum fixes the date of Dr. William Roxburgh's own residence for a twelvemonth at the Cape as 1799 and that an entry in the Hortus Bengahnsis (p. 54), written by Roxburgh himself, shows that his 30 TTTE .TOURXAL OF BOTAXT son John was In South Africa in ISOl, a year which falls within the period alluded to hv Don. As the writer had occasion to explain in his " Memoir of Francis Buchanan (afterwards Hamilton)," Roxburgh left Calcutta for the Cape early in 1798 ; a letter dated 16 October, 179S, was sent to Roxburgh from India and reached him while he was in South Africa ; in October 1799, Roxburgh had just returned to Calcutta from the Cape. We know that on the return voyage Roxburgh's vessel was detained at Madras sufficiently long to admit of his being received in audience by the second Lord Clive, then Governor of Fort St. George. There must have been a corresponding detention at Madras on the outward journey, and the known facts render it reasonable to surmise that in 1798 the Moravian brethren, satisfied that John Roxburgh now knew all they could teach him at Tranquebar, handed him over to his father as fit for the latter's " Assistance " during this South African visit. The matter of John Roxburgh's age in 1798 is of secondary im- portance. We know that Roxburgh, as was usual with medical officers towards the close of the XVIIIth Century, made several voyages as Surgeon on East Indiamen before he was definitely appointed to the Medical Service of the H.E.I. Company. The dates of these voyages have not, however, been supplied us by Dr. Roxburgh's biographers, and we have as 3^et no knowledge of his various ports of call. When, at last, his definite appointment came about, we know that he took up his duties at Madras in 1776. The probability^ therefore, is that in 1798, when Roxburgh asked the Moravian brethren to let him have his boy back, the latter was at most somewhere about sixteen. He cannot, then, have much more than attained his majority when he accompanied his father to the Cape in 1798 or joined his father there in 1799. The young- man appears to have given his father such satisfaction as a botanical collector while m his company that Roxburgh decided to leave John behind, to collect South African seeds and plants and herbarium specimens, when he himself returned to India in 1799. Leaving " John " Roxburgh in South Afriqa, Ave now turn to "Roxburgh , junior," cited by his father (Hort. Beng. p. 56 and Flora Indica, vol. iii. p. 338) as author of the name Flfmuigia frostrata. The individual alluded to was William Roxburgh, junior {Flora Indica, vol. i. p. 554), whose name is associated in the first volume of that work with the finding of fifteen species, in the second volume with the collection of six species, in the third with the discovery of twelve, and in the supplementary Tcryptogamic) portion, which Griffith first had ])rinted in the Calcutta Jo2(rnal of Natural Ifistori/ in 1814, with the communication of eleven species. As in the case of " John " Roxburgh, we do not yet know Avhere or when William junior, was born. In William's case, moreover, we are unable to say where or how he was educated. We know, however, that by 1799, when his father returned from the Cape, he had reached an age which justified the Government at Fort William in appointing him Assistant to the Superintendent of the Calcutta Botanic Garden. A letter from Mysore written in 1800 by Buchanan to Roxburgh "JOHN" ROXBURGH 31 contains tlie passage : — " I congratulate you on William's appoint- ment. Although it certainly would have been better to have got him a Writer, yet the garden will be a handsome provision for him, and with the opportunities he will have under your tuition he will soon become a proficient." It seems clear from this letter that Buchanan believed that William's appointment carried with it, if not the right, at all events the prospect of succeeding his father. A youth of great energy and much promise, William Roxburgh, junior, at once entered on a career of active botanical exploration. He spent a considerable portion of the year 1800 at Avork in the Rajmahal Hills (Flora Indica, vol. ii. p. 51). When Buchanan, who was a personal friend and correspondent of the younger man as well as of his father, became aware of this, he at once expressed his disappointment. '* I am very sorry," he remarks to Dr. Roxburgh in a letter from Mysore, dated 31 January, 1801, "that William has gone to the Rajmahal hills. If possible, send him to Chittagong — an immense held remains there, by far the best I have seen in India." Roxburgh followed Buchanan's advice ; during 1801 William was at work in Chittagong (Flora Indica, vol. i. p. 81). By the time that William returned Buchanan had completed his Mysore survey and had joined the embassy led by Captain Knox into Nepal during 1801-2. Roxburgh endeavoured to secure William's attachment to this embassy and on 22 February, 1802, wrote to Buchanan explaining his wishes. Replying from the Nepal frontier on 2 March, 1802, Buchanan said " I shall be very happ}^ if you succeed in sending William : but I am affraid you will not meet with success in the application to Government for the purpose." Buchanan had, in fact, discussed the proposal with Captain Knox, who explained to him that the Nepal Durbar had already objected to the number of English officers attached to the Embassy. The anticipation was correct ; Grovernment did not permit William to cross the Nepal frontier. The dated entries in the Hortus Bengalensis show that William was still in Chittagong at the beginning of 1802 and that he collected in Bengal on his return journey, probably in the Sundribuns. When he reached Calcutta his father appears to have arranged that William should proceed to Penang, and although none of the Penang collections alluded to in the Flora Indica are dated, all the dated ones in the Hortus Bengalensis were secured in 1802. After having investigated Penang we find from the Hortus Ben- galensis (pp. 1, 11) that William visited the Moluccas, returning thence to Sumatra, where he was employed during 1803 (Flora Indica, vol. i. p. 70; Hort. Beng. pp. 1, 63, 65, 69) and 1804 (Flora Indica, vol. iii. p. 457 ; Hort. Beng. pp. 43, 69). In the following year William was once more at the Botanic Garden with his father; for the solitary name, Flemingia prostrata, which Roxburgh has attributed to his son, was bestowed by the latter on a plant "raised from, seed sent by Mr. Kerr from China to the Botanic Garden in 1805, where they blossom about the close of the rains in November and ripen their seed during the cool season." This indirect reference is the last we can find to William Roxburgh, junior, and the suggestion that William died soon after the cold 32 THE JOUEXAL OF BOTANY weather of 1805-6 is strengthened by the circumstance that when Buchanan, who was at this time on furlough in England, returned to India early in 1807, he brought with him a nomination from the Court of Directors as successor to Roxburgh when the latter should retire. That the name John Roxburgh should be absent from Mr. N. Bonham-Carter's "family-table" printed by Sir George King, is due to the fact that he was not the son of one of the three ladies whom Dr. William Roxburgh married. More difficult at first sight is the task of reconciling Mr. Bonham-Cai-ter's "family-table" with the known facts in the history of William Roxburgh, junior. This William was the active coadjutor of his father during the height of Dr. William Roxburgh's career. Yet Mr. Bonham- Carter's chart shows that the only William, junior, of whose existence his family was aware, was the j^oungest son of Dr. Roxburgh by his third wife. Sir George King, fully realising the difficulty, has suggested that the name attributed by the Bonham- Carter family to Roxburgh's youngest son may be erroneous. To the courtesy of the late Mr. Frederick Henry Norman, also a descendant of Dr. Roxburgh and his first wife, the writer is indebted for another family-table which agrees with that ])rinted by Sir George King save in two particulars. It queries, as Sir George King had independently queried, the accuracy of the name William as applied to one of Roxburgh's sons by his third marriage ; it states that, by his first wife, Roxburgh had a son William, brother-uterine of Mary Roxburgh, from whom both the Norman and the Bonham- Carter families are descended. This son, Avho is shown in this table as senior to his sister Mary, died young. The Writer is further indebted to the courtesy of Miss Mary Ann Tucker, granddaughter of Dr. Roxburgh and his third wife, for yet another family-table, which agrees substantialh" with that of Mr. Bonham-Carter and shows that one of her uncles, brother-uterine of her mother, really was named William Roxburgh. The difficulty then is purely imaginary. There were two William Roxburghs, junior; the eldest and the youngest of Dr. Roxburgh's laAvful cliildren were named after their father. The statement in the Norman " family-table " that the first " William Roxburgh, junior " died young, is coiTect in the sense that this William Roxburgh, junior, had died before the second William Roxburgh, junior, was baptised. But the first "William, junior," whose name recui*s so frequently in his father's published works, lived sufficiently Ions; to become his father's Assistant and to accomplish much notable botanical exploration. His claims to recognition, and to an honourable place in the Biograpliical Index of British ami Irish Botanists, are by no means confined to his association with the name Fhmingia prostrata Roxb. f. The nomination of Buchanan as Roxburgh's successor in 1806 is not the only circumstance which points to this as the year in which William Roxburgh died. About the same time the residence of John "JOHN EOXBURGH 33 Roxburgh at the Cape came to an end. When John returned to India from South Africa is not detinitely known ; after his return he was employed under his father in the Calcutta Botanic Garden. As his missionary guardian explained in 1793, John's genius was " but of the middle sort." This may account, at least in part, for his a]>pointment to a subordinate executive post. It may also explain why, in the Flora Inclica, there is but one reference, and that a reference which might easily be overlooked, to his work as a collector. The passage in question {Flora Indica, vol. ii. p. 169) informs us that Tacca aspera was " found by Mr. J. R. indigenous in the vallies amongst the hill behind Chittagong." But his activity as a collector during the years 1810 and 1831 w^as very marked and, as the Editor has pointed out, the Hortus Bengalensis records the introduction by him of many plants from Chittagong. For 1810 we find such records on twent3^-five pages of the Hortus for Chittagong alone, and an examination of the entries suggests that on his way to Chittagong he collected in the Sundribuns ; that while in Chittagong he gave especial attention to orchids ; that on his way back from Chittagong he was able to reach Silhet. In 1811 he was again active, though for this year his records occur only on about half as many pages of the Hortus. When Roxburgh, broken in health, left India for the last time in March 1813, John Roxburgh was Overseer of the Botanic Garden. He held this post during the various changes in the superintendent- ship w^hich marked the period betw^een March 1813 and August 1817. Not long after Dr. Wallich's definite appointment as Superintendent took place in 1817, incompatibility of temper led to differences be- tween the new administrative and the old executive head of the establishment. John Roxburgh thereupon ceased to be a member of the staff. Whither he moved or when he died we do not know. While none of the sons of Dr. Roxburgh by his second wife can be claimed as botanists there is an indication that the eldest of this family, George Roxburgh, might have developed into a collector had he not, as the Bonham-Carter " family- table " explains, been "killed by lightning in Java." We know, from the Flora Indica (vol. iii. p. 380), that his father was indebted to George for specimens of at least one species from Hardwar. Two other sons of the same family, Bruce Roxburgh and James Roxburgh, though in no sense botanists, have claims to the gratitude of botanical students which it is not easy to repay. To their filial piety w^e owe the publication in 1832 of their father's Flora Indica, and on this account readers of the Journal may be interested to know the outlines of their careers, for the par- ticulars of which the writer is indebted to the kindness of his friend Mr. W. Foster, CLE., of the India Ofiice. Bruce Roxburgh, according to the various family-tables the third son and fourth child of Dr. William Roxburgh by his second wife, is recorded officially as having been born at Calcutta on 12 December, 1797. It seems possible, however, that in this instance the date recorded is that of baptism, not that of birth, for among the letters addressed to Roxburgh by Buchanan is one, written on 4 September, 3-1 THE .TOURXAL OF BOTANY 1797, which ends with a message of congratulation on the birth of this child. Bruce Roxburgh entered the service of the H.E.I. Coinpan}^ on 21 April, 1815 ; became Cornet, VI. Bengal Cavalry, 4 October, 1816 ; Lieutenant, 1 September, 1818 ; Captain, 1 De- cember, 1829 ; was transferred to the Invalid Establishment, 31 August, 1831 ; retired on medical certificate, 13 September, 1832 ; and died 14 June, 1861. Though he joined his younger brother James in financing the publication of the Flora Indica, it seems clear that the state of his health must have prevented him from taking any very active part in the correspondence which brought about the production of the work. James Roxburgh, the fourth son and seventh child of Dr. William Roxburgh by his second wife, is recorded oificially, and in this instance probably correctly, as having been born in India on 25 January, 1802. In a letter dated 11 March, 1802, in which Buchanan informs Roxburgh that he had received " a letter from William," written doubtless after William's return from Chittaoonop and just as William was preparing to leave- for Penang, the con- cluding sentence reads : — " Be so good as to accept of m}^ congratu- lations to you and Mrs. Roxburgh on the increase to your family and present my compliments to Miss Roxburgh and William." James was nominated to the service of the H.E.I. Company by John Thornhill, Director, on the recommendation of his brother-in-law, Henry Stone (husband of the Miss Roxburgh referred to by Buchanan). He became Ensign, XIX Native Infantrv (Bengal), 14 February, 1820; Lieutenant, 11 July, 1823; Captain, 12 No- vember, 1832 ; Major, 18 November, 1846 ; permitted to retire from the Army, 28 November, 1849. On 30 December, 1835, he was transferred to the Military Auditor's Department and appears to have served in that department till his retirement. After his transfer to this branch of the service it is on record that "the Madras Government authorised the purchase of nine copies of a botanical work written by the late Dr. Roxburgh, the Company's Botanist, called ' Flora Indica,' published by him (Capt. Roxburgh) in conjunction with his Brother, Capt. B. Roxburgh." Shortly thereafter he was " permitted to place at his own expense a suitable building over the column or monument erected in the Botanical Gardens in 1822, to the memory of his late father." The inscription on the monument that James Roxburgh thus so thoughtfully pro- tected may be found by the curious at the end of the preface to the reprint of Roxburgh's Flora Indica which we owe to the public spirit of the late C. J3. Clarke, issued at Calcutta in 1874, ten years before the death of James Roxburgh. - WETGHTXCr MOORTXOS 30 WEIGHINa MOORINGS. Br A. H. Chitrch. From the stindpoint that the algae constituting the phytobenthon of the sea may be preferably regarded as anchored, (hormon), the problem of the security of the moorings becomes one of primary significance, and conditions clearly vary within wide limits according as the bottom consists of mud, sand, shingle, or clean rock. The fact that the larger algaj require good holding-ground of rock, while sandy coasts are comparatively bare of all vegetation, is sufficiently obvious ; and it has been pointed out elsewhere that this has had a remarkable influence on the history of algology, more particularly in countries where the coast is predominantly of sand-dune formation. The case of mud is more satisfactory, since, owing to the cohesive nature of its slimy texture and the effect of bacterial zooglcea in binding the surface-film, the substratum may be able to bear con- siderable movement of the superjacent medium, while algae with rhizoid attachment may penetrate considerable depths and assist in binding the surface to constitute good anchorage for plants of con- siderable size, as Chorda, 10 ft. or more, in close association. A mudd}^ bottom may thus carry a distinctive flora when a sandy shore, owing to the readiness with which the particles are lifted by surge- action of the water, affords no secm-ity at all, and may present no characteristic plants beyond loose-h'ing calcified Litlioth amnion, which are practically pebbles. As the specific gravity of such sand- j^articles may be taken as little over 2, it may be noted that a stone in sea-water loses nearly half its weight, while irregular shapes offering considerable " form-resistance " may considerably delay the rate of sinking. The surging action of the waves, as an upward thrust, may thus if sufficiently violent maintain in suspension par- ticles of considerable size ; and the scour of the sea-shore by particles and pebbles so lifted, is in fact the commonplace of the sea, and con- stitutes one of the factors limiting plant-life on " exposed-coast " ; but it also expresses the insecurity of the moorings of smaller algas in such biological stations. A further means of moving particles of even considerable size is noted in the evolution of bubbles of photo- synthetic oxygen which are so extensively utilized for the erection of axes, as in rounded types of lacunar and hollow thallus, or the differen- tiation of special members, pneumatoj^hores with pneumatocysts {AscopJiyllum, Sargassum, Macrocystis), culminating in the 6 ft. bladder of Nereocystis. Since the pull of such erecting bubbles con- stitutes a further strain on the hapteron- system, such forces may combine to exert a considerable lifting effect on the substratum ; and where the holding is insecure the plant-soma may be lifted off its bed, thus weighing its moorings, to be drifted out to sea. or in shore, according to the direction of the tide or current-flow. Thus Professor Oliver, for Blakeney (1912, in lecf.), has described the germinating zoospores of Unteromorplia on exposed wet sand, actively photosvnthetic and attached to individual sand-particles of •25-*3 mm. diam., floated off by the incoming tide, each supported by its bubble of oxygen. The most striking example of the effect of 36 THE JOURNAL OF BOTANY such phytosynthetic bubbles is that of Colpomenia sinuosa, a Medi- terranean Phseosporean, which appeared in 1906 at Vannes in the Gulf of Morbihan (Belle Isle), growing attached to oysters. The plant became an economic nuisance, and is known as the Oyster-thief (Voleuse dliuitres) (cf. Cotton in Kew Bulletin, 1908, p. 75). The thallus of pareitchymatous organization and papery texture is hollow, and may attain the size of a hen's e^g or tennis-ball, as a " balloon." On active photosynthesis in shallow water the cavity so fills with internal gas-bubbles that on the return of the tide the inflated balloons weigh the young oysters to which they are attached and float them out to sea. The number of oysters so carried off was so considerable that attempts were made to recapture them by nets, while faggots were dragged over the beds in the hope of tearing the thallus-balloons. The story is usually approached from the stand- point of the oyster-owner, but it shows that Colpomenia merely attaches to the oysters in such a station for want of better anchorage, while the final disaster is possibly greater in the case of the plant than in that of the animal. The point of interest is that the majority of the oysters so weighed are lost, not cast on shore, and the effect of weighing moorings generally is to be carried out to deep water rather than to be thrown up. There seems to be no means of obtaining an estimate as to the relation between the amount of sea-weed detached and throw^n on shore and that drifted back to deep water, to exist as *' loose-lying " vegetation, or to sink and die in the open sea. Immense quantities of weed thrown on the beach by one storm may be swept out to sea again by a succeeding tide. The amount of weed thus cast up as flotsam and jetsam which might be economically utilized is probably but a very small proportion of the wastage of the sea, as expressing the amount of increase over what the station will carry. Further observations on the lifting of stones of considerable size have been recently made by Mr. Spence at Orkney in the case of the larger Laminarians {cf. Journ. Bot. 1918, p. 281). Thus L. Cloustoni, thougli usually growing on rocky bottom will bring ashore stones of 6-8 lbs. weight. In one case 9 large Laminarias, of which one was L. fiexicaidis, were brought in attached to a stone of over o6 lbs., or an average of 8 lbs. per plant, whose weight might be 3-5 lbs. each. iAL OF BUTAXl' curiously enough quotes E. purpiirata Sm. (varletas bracteis evolu- tissimis) as identical with his JE. Hellehorine 3. varians {viridijlora)^ giving Surrey and Boxhill as respective localities. Bark's figure (Icon. t. 7) is noteworthy for the pubescence of the upper stem and ovary, and for the hairy poUinia. This is the earliest indication by any author of the outgrowth of pollen-tubes, in situ, on the poUinia, which was first described by Hermann Miiller (Yerhandl. d. N. H. Ver. preuss. Kheinl. &c. 1868). It is necessarily exaggerated, and the hairs appear black, Avhereas they are really as clear and colourless as glass, but it would be impossible to show this on the scale of the figure. He does not mention it in the text, but the indication in the figure is sufficiently remarkable. Rouy's description (Fl. France, xiii. 204) fits our plant accurately as far as it goes, but it is silent as to the column, anther, stigma, and rostellum. Like Rouy, Ascherson and Graebner (Syn. Mitt. Europ. Fl. iii. 862) treat it as a race of _£J. latifolia, their description showing some advance on previous ones, as it notices the absence of a rostellum (which is present in our plant in newh^-opened flowers) and mentions that self-fertilisation occurs. As our plant, while specifically identical with the continental one, has certain marked characteristics of its own, is constant in the limited area in which it grows, and differs from the forms dunensis and vectensis referred to above, I jDropose to describe it as a new variety * : — Epipactis YiRiDiFLOEii Rchb. var. nov. leptochtla. A typo differt caulibus altioribus (2-7 dm. ) sa^pe aggregatis ; foliis inferioribus ssepe ovatis ; sepalis acuminatis 12-15 mm. longis, 4 mm. latis ; lobello protinus prominente; hypochilio orbiculari 4 mm. diam., 3—4 mm. alto; epichilio cordato acuminato (cuspide longa acuta) angustissimo (+8 mm. longo, 4 mm. la to, ubi latissimum est) viridi albomarginato ; caUis duobus irregulariter rugosis albis interdum pallide roseis ; rostello evanescente. Diifers from the type as follows : — Stems taller (2-7 dm.), often clustered. Lower leaves frequently ovate. Sepals acuminate 12- 15 mm. long by 4 mm. broad. Labellum projecting forward. Hypo- chile orbicular, 4 mm. in diam., 3-4 mm. deep. Epichile cordate acuminate, with long acute point, very narrow ( + 8 mm. long by 4 mm. broad at widest part), green, bordered white. Bosses two, irregular rugose, w^hite, sometimes faintly tinged pink. Rostellum evanescent. Stems clustered in older parts, 20-70 cm. tall. Leaves ovate to broadly lanceolate, upper lanceolate tapering, all acute, often wavy-edged, yellow-green or dark green, not grey-green. Internodes short. Sepals long, acuminate, 12-15 mm. long by + 4 mm. broad. * The differences between Mr. Stephenson's forma (:^)^He/^6•^s and typical viridi- flora are considerably greater than those between many recognized varieties ; indeed, I am inclined to think that dunensis has gone far on the road towards differentiation as a species. It appears to be fully entitled to rank as a variety, much more so, for instance, than E. pnlustris var, erketoru m Asch. & Gracbn. EPIPACTIS YIRIDIFLORA REICH. 30 Lahellum shorter than sepals + 10 mm. long, 4 mm. broad. IJ^ypo- chile small, nearly circular, 4 mm. in diameter, 3-4 mm. deep, green within, mottled with jmle pinkish red near the base, edges semi- transparent, wavy, irregularly crenate. Einchile cordate acuminate, with a long acute point + 8 mm. long by 4 mm. broad, greenish, w^hite-bordered, not deflexed ; bosses distinct, low, rugose, vvhite, sometimes tinged faintly with pink. Column rising in a curved nib- shaped stalk (filament) in the centre at the back, on the apex of which stands the anther ; on each side is a V-shaped incision in the wall of the column, the anterior side of which rises into a tooth or staminode at its junction with the stigma. Anther ovate, with a bluntly-pointed empt}^ apex, projecting for upwards of half its length over the upper edge of the stigma. Stigma transversely oblong, a prolongation of the front of the column, not supported on a pedestal at the back as in E. latifolia ; upj^er edge sloping slightly downwards from the centre to the tooth (staminode) at each corner. EosteUum present when the flower first opens, but functionless, quickly disap- pearing, leaving a brownish mark. The gland contains viscid matter, but this is too weak to remove the pollinia ; moreover, it does not appear to come in contact with them, for, instead of being opposite their united apices, it lies, owing to the forward position of the anther, opposite the V-shaped space between the downward-diverging pollinia, so that the latter, in sliding downwards, pass over the viscid gland without touching it. As compared with the forma vectensis Stephenson, the following differences are observable : — Yar. LEPTOCiiiLA. Stems clustered, 20-70 cm. tall, pubescent below, rather densel}^ so above. Leaves yellow-green or dark green, lower ovate, sometimes broadly lanceolate. Lower bracts twice as long as flowers. Baceme many-flowered, up to 23 cm. long. Flowers as large, and opening as widely as in E. viotacea. Forma tectensis. Stem solitary, delicate and slender, almost glabrous below, slightly pubescent above. Leaves grey-green, lower lanceolate to elliptic lanceolate. Lower hracts never much exceeding the flowers. Raceme lax, few-flowered. Flowers small, green, never opening so widely as in violacea. In English Botany, ed. 3, ix. 123, E. media " Fries " Babing- ton (as sub-spec. I of E. Hellehorine Cr.) includes two forms : — - var. CI. viridis (E. viridijlora Hoffm. is quoted as a synonym) and var. f>. pur pur at a Sm. i^E. violacea^. The question therefore requires consideration as to whether E. viridijlora and E. violacea are in reality forms of one species. They are in some respects more closely allied than E. viridijlora and E. latijolia, as they agree in two remarkable characters in which the}^ both differ from the latter ; they have a similar root-system — a knotted rhizome with fleshy rootlets growing from the nodes at diflterent levels (in latijolia the rootlets spring from the base of the stem at the same level), and the older plants have clustered stems, at least this is so in the variety lejjto- chila. The following comparison shows the main points of difference between the two plants : — 40 THE JOUllXAL OF J30TANY E. VIRIDIFLORA Var. LEPTOCHILA. The neiv hud has only one root- let, on the outside, furthest from the stem. Stem pale green. Leai'es often numerous, near to- gether, internodes short, lower often ovate, sometimes broadly lanceolate, upper lanceolate to linear lanceolate, yellow-green or dark green *. Raceme lax. Sepals lanceolate, acuminate. Petals ovate- lanceolate, acumi- nate, very acute, nerves clearly visible. Epichile. Not deflexed, cordate acuminate, with a long acute point, longer than broad (8-9 mm. X 4 mm.) green, with 2 white rugose hunches. Column rises into a nib-like tooth at the back, with a deep acute sinus between it and the staminode on each side. Anther stalked, projecting far over edge of stigma, so that the viscid gland is opposite the V-shaped space between the downward- diverg- ing pollinia. Viscid gla nd. Functionless, wither- ing by the time the flower above it opens, not coming in contact with with the pollinia. Ripe capsule yellowish green, elliptical, broadest in the middle, jfl2mm. long and + 8 mm. broad; stalk + 6 mm. long. The flower is self -fertilized. E. VIOLACEA (E. purpurata S.n.). Each bud has two rootlets, one on each side between bud and stem. Dark grey-green, tinged through- out with violet, giving it a curious mealy and livid appearance. Distant internodes long, lowest never ovate, all similar in shape, dull grey-green sometimes flushed with violet, much smaller, shorter, and narrower f. Raceme much denser. Lanceolate obtuse, sometimes rather acute. Oblong- lanceolate, obtuse, the same breadth for most of their length, nerves almost obsolete. Deflexed, cordate acute, broader than long (4 mm. long by 5-6 mm. broad), white, very faintly tinged pink, with 2-3 parallel + confluent hunches. Upper wall continuous, wavy- edged and level from centre of back to staminode. Sessile, not projecting over upper edge of stigma (except the empty tip) ; gland opposite apex of pollinia. Large and very effective, firmly attached to pollinia just below their apex. Dark grey-green, markedly tri- gonous, broadest just below apex, + 20 mm. long, each side 10-11 mm. broad at the widest point; stalk + 3 mm. long. Fertilized by wasps. The above-marked points of difference, extending to most jmrts of the organism, appear amply sufficient to prove that we have in these plants two good and distinct species, and a careful examination of the essential organs of the flower will show that ^. laf /folia, viridijloray and violacea are morphologically different. It is true that many botanists have considered vi rid {flora, and several violacea, to be but forms of E. laiifolia, but all these authors have given judgement without taking into account the evidence afforded by the anther, pollinia, stigma, and rostellum, their descriptions stopping short at the perianth. Nevertheless, there have been clear-sighted botanists who, apart from the organs of reproduction, have recognized that the * Ovate lower leaves vary from 7 by 5 cm. to 5 by 4 cm. ; lanceolate lower leaves from 10 by 3^ cm. to 6 by 2 cm. t Varying in length from 4-7 cm., in breadth from 2-2J cm. EPTPACTIS YIKIDIFLORA RETCIT. 41 differences between these plants are of sj)ecific rank. For, indeed, to the eve trained by observation of the living plants, the three species are recognizable at a glance in most stages of their growth. Max Schulze (Orchid. Deutschl. No. 54) considers that E. vio' lacea is a good species, but thinks that E. latifolia and E. viridi- ilora can hardlj be distinguished, though he admits that their extreme forms are so different as to suggest two species. He says that numerous intermediate forms occur, in which all the leading characteristics show great variation, so that it is difficult to tell whether a plant belongs to one or the other. This is a recrudescence of the old idea, which dies so hard, that two recognizably different plants, if intermediate examples occur, must belong to one and the same species. Sir J. D. Hooker {Life and Letters, ii. 34) Avrote to Darwin (Oct. 2, 1862) "The dismal fact you quote of hybrid trans- itions between Verhascum Tkapstis and nigrum , . . . and its bearing on my j^ractice of lumping species through intermediate specimens, is a very horrible one .... Your orchid book has convinced me that such cases must be abundant." It is curious that Schulze should have followed this time-honoured practice, for he knew and described many hybrid orchids. Perhaps the frequency of intermediates between E. latifolia and viridijiora blinded him to the probability of their hybrid origin. He appears to have overlooked the fact that, as viridijiora is self-fertilizing, we might reasonably expect that any hybrid between itself and latifolia should also be self-fertilizing. Its offspring would be partly like itself, and partly tending to resemble more closel}?" one or other of the original parents. In this way a number of intermediate plants might arise, and a great range of variation occur, where the two species grow together. A parallel case occurs with the self -fertilizing Ophrys apifera. J. T. Moggridge states (Journ Linn. Soc. viii. ]). 258) that Oplirys Scolopax appears under two forms. He says, referring to the latter, " At Mentone I never saw any tendency to self-fertilization, but all the spikes of a large bundle sent me from Cannes were so Avithout exception. It is a remarkable coincidence that at Mentone the Bee Ophrys is scarce, and at Cannes very abundant. So, within 30 miles of one another, we have one spot where self-fei-tilization is in full action, and another, where it is, as far as I am aware, unknown." Evidently at Cannes hybrids have occurred between the insect-fertilized O. Scolopax and the self -fertilized O. apifera. and their offspring, taking after the latter parent, are self -fertilizing also. There is nothing to prevent the self-fei-tilizing hybrid from multiplying freely and becoming abundant. Tlie correctness of this supposition appears to be confirmed by Moggridge himself, who says that the difference between the self-fertilizing O. Scolopax of Cannes, and the insect- fertilized Scolopax of Mentone is brought about " by a very slight bend in the anther-cells, which are prolonged into a beak of variable length in tlie case of the self-fertilizing blossoms." This prolonged beak is one of the most striking features of O. apifera, and betrays the parentage of the Cannes Scolopax. The fertilization of leptochila differs somewhat from that of dunensis. In the latter the poUinia are extremely friable, and, even Journal of Botany. — Vol. 57. [FEBErAET, 1919.] e 42 THE JOURXAL OF BOTANY before the flower opens, numerous tetrads of pollen fall on the lip, into the hypochile, etc., and probably thus become transferred to the stigma. In the former the pollinla slide downwards bodily from the anther-cells over the sloping upper edge of the stigma, and come to rest obliquely on its frontal viscous surface, to which they become anchored by an outgrowth of pollen-tubes, in much the same way as described by H. Miiller {oji. cit.) in the case of the continental viridijlora. THE GENUS HERBERTA AS REPRESENTED IX THE MaX^CHESTER MuSEUM. Br William Henry Pearson, M.Sc, A.L.S. Prof. A. W. Eyans of Yale University has done a great service to British hepaticologists in his "Notes on the genus Herberta, with a revision ot" the species known from Europe, Canada and the United States" published in the Bulletin of the Torrey Botanical Chih for 1917 (pp. 191-22), wherein are described and figured two British plants which have hitherto been considered as forms of one species — Herherta adunca (Dicks.) and //. llutchinsice (Gottsche) Evans. In 1862 Gottsche (Pabenhorst Hep. Eur. n. 210) discriminated the two forms; Carringtonin his Gleanings among the Irish Cryptogams (1863) has an interesting note in which he regarded H. adunca as a form found only on high and exposed mountains ; the habitat he thought accounted for the differences and he did not separate them. Evans proves by the different characters that they may justly be considered distinct : for full descriptions reference must be made to his paper ; I merely give here the salient characters of the two species. Herberta adunca (Dicks.). Leaves bifid to about one half; divisions broad, slightly or not at all curved, acute or acuminate : vitta not distinct, usually indistinct even in the basal region, extend- ing for a short distance into the divisions, but coming to an end con- siderably beloAV the apex. (The vitta or nerve is a band of elongated cells which extend from the middle of the base of the leaves to the segments.) Basal portion of leaf normally entire. Herberta Hutchinsi^e (Gottsche) Evans. Leaves bifid two- thirds to four-fifths, divisions narrow, strongly curved, long-acuminate ; vitta distinct, extending far into the divisions, but hardly to the apices. Basal portion of leaves entire or nearly so or furnished with a fev; teeth. Of this species Prof. Evans gives a plate. H. adunca is recorded from Scotland and Wales ; H. Ilutchinsice from Scot- land, England, Wales and Ireland : the further distribution of the former is Norway and Faroe Islands, and of the latter, Norway-, Alaska and British Columbia. Another European species — II. Sendtneri CNees) {Sendtnera Sauteriana Nees, Schisma straminrum Dum.) — has been credited by Dumortier and Lett to Scotland, but no specimens have been seen to support fhe statement. A large form of H. adunca collected bY C. Howie (near Loch Maree, llosshire) has been so named, but there THE GEXUS HERBERT A 43 is nothing to separate this from the normal form of adiuica, the base of the leaves being quite entire, whereas in II. Sendtneri the large teeth at the base of the leaves are very characteristic of the specie?. Evans raises to specific rank as H. tenuis^ a small form found only in North America. Stephani describes seventy-one species of Herherta {Schisma), and four more have been added, making a total of seventy-five; of these about twenty are represented in the Manchester Museum from the localities given in the following list : — H.

Small" (^Oxalis) ; others although not entirel}^ new are unfamiliar, such as Cymhalaria Cyinhalarla "(L.) Wettst." and Kickxia Flatine *' (L.) Dumort." {Linaria). The material upon which the book is based was the result of various exj)editions carried out by Dr. Britton and Mr. Stewartson Brown between 190-5 and 1918, with the assistance on some occasions of Mrs. S. Britton and Dr. Seaver. A list of the " principal botanical collections made in Bermuda " and a bibliography are appended : it would appear from the former that no plants were collected there between 1699 — the latest date of John Dickinson's gatherings — and A. W. Lane's collections made prior to 1845, Dickinson — here and elsewhere misspelt Dickenson — really collected considerably earlier, for Petiver (Mus. Pet. viii, 80; Dec, 31, 1700) acknowledges "plants lately sent from Bermudas (besides 2 collections some ^^ears agoe) with assurances of larger performances." These ** assurances " do not seem to have been realised, as only thirteen species labelled as from him are in the Petiver and Plukenet collections in the Sloane Herbarium, Of these five are of special interest : atten- tion was tirst directed to these by Dr. Hemsley in this Journal for 1883, where Ei'if/eron JJarrellianus and Carex hermudiana were lirst described : the latter was only known from Dickinson's specimens until 1905, when it was rediscovered by Dr. Britton. The endemic Sist/7'inchium, long confused with S. ouf/usti folium Mill., was shown to be distinct by Dr. Hemsley in this Journal for 1884, and is still so regarded: Dr. Britton says " it doubtless originated, however, from seed of one of the Continental species bi'ought to Bermuda by a bird or on the wind, the plant becoming differentiated through isolation 46 THE JOUltNAL OF BOTAJ^Y from its parent-stock." A similar explanation is given, though some- Avhat more cautiously, of the origin of another endemic species, Chiococca hermudiana, which "probably originated from seeds of C. alba.'''' Tlie name Hermudiana, which is here retained for the Sisy- rinchiiim must, as Mr. Farwell points out in a paper reprinted in this Journal for 1918 (p. 271), be assigned to the species generally known as S. angustijolium ; the Bermuda plant must be called &. iridioides Curtis, whose beautiful figure (Bot. Mag. t. 04) contrasts favourably with that given as frontispiece to the book under notice. The plant here called Galium hermudense L. is regarded — perhaps rightly — as conspecific with the United States species included by Linnseus under the name. The matter is discussed in this Journal for 1909 (p. 41) in a paper which seems to have escaped Dr. Britton's notice ; in this the two are differentiated, and the name hermudense is restricted to the Bermudan plant, which is called Relhunium hernmdense. The fifth of Dickinson's endemic species is Adiantum helium, first dis- tinguished in 1879 by Thomas Moore, " who," as Dr. Britton informs us, " was not the same man as the celebrated poet of the same name " — it is not easy to suppose that anyone would be likely to consider the two identical ! The other Bermudan species represented in the Sloane Herbarium by specimens from Dickinson are Melilotus indica AIL, Erif/eron canadense L., E. linifolius Willd., Eupatorium macro- pliyllum L., Verbena urticifolia L., SclerocJiloa rigida Link, and Cenchrus trihuloides L. Petiver also received from him Juniperus hermudiana in fruit; of this species there is in the Sloane Herbarium labelled by Petiver: '^ This from Bermudas a D. (vol. 332, f. 81) James and Dickinson ": I have not met with the former name elsewhere. Another early collector was the Eev. William Clarke (fl. 1710-34), Avhose plants, gathered at Carolina, Bermudas, and the Caribees, are in Herb. Sloane, vol. 318. Unfortunately the localities for the speci- mens are not distinguished in any way : that some are from Bermuda is, however, shown by a specimen (f. 34) of the endemic Erigeron Earrellianus. It may be noted that Dickinson gives two local names which do not appear in the jFZor«: "Love-grass" for the Cenchrus — "I sup- pose," says Petiver, "from their prickly seeds, which may stick to j^ cloaths like our Burdock or Clivers, wh. last for y*^ reason is called Philanthropos " — and "Hog weed" ior Erigero7i Earrellianus : we note that Dr. Britton, conforming to the absurd fashion which would supply every plant with an " English " name, dubs the latter "DarreU's Fleabane," which it is safe to say no one ever has called or ever will call it. The index — evidently excellent, although the first name we looked for {lielhunium, p. 308) does not appear in it — demands a special word of praise in that there is but one : a method which, often urged in these pages, is emphasized by Sir Edward Cook in his recent delightful volume. Literary Becreations (p. 63): writing on "The Art of Indexing " he says : " I lay down as the first rule, One book. One index. . . . Multiplication of indexes is an unmitigated nuisance: it makes reference less easy. One index alphabetically arranged is the only right plan." BOOK-XOTES, NEWS, ETC. 47 BOOK-NOTES, NEWS, etc. ALTHOuaii he did not die on the field of battle, Reginald Philip Gregory may be added to the list of those for whose loss the War, in the prosecution of which he had been engaged since 1915, must be held res^Donsible. In the year named he obtained a captain's com- mission in an officer cadet battalion at Cambridge, and in July 1917 went to France with the 1st 6th battalion of the Gloucestershire Regiment. He was badly gassed in the trenches, and never com- pletely recovered ; discharged from the army in October last, he resumed his tutorial work at Cambridge, where he was University Lecturer in Botany, but succumbed on Nov. 24 to an attack of pneumonia following asthma. Born at Trowbridge, Wilts, on June 7, 1879, he early took up botanical pursuits under the guidance of his mother, whose name is familiar to British botanists in connection with the genus Viola. Going up to Cambridge, he took first-class honours in both parts of the Natural Science Tripos, and in 1904 gained the Walsingham medal for an essay embodying the results of original research in botany. Yv^'e take the following summary of his work from a memoir contributed to Nature (Nov. 28, 1918) by Prof. Seward : — " Mr. Gregory ivas one of a group of students who were stimulated by the teaching and enthusiasm of Prof. Bateson to take up different branches of genetics ; it was mainly with cytological problems that his researches were concerned. His most important contributions were those dealing with the genetics and cytology of giant races of Primula, published in the Journal of Genetics (1911) and in the Proceedings of the Royal Society (1914). His work demonstrated the striking fact that some forms of Primula exhibit the giant character not only in the plant-body as a whole, but also in the constituent cells. The results obtained constituted a definite advance in our knowledge of phenomena connected with the re- duplication of certain terms in a series of gametes. His researches also included the investigation of heterostylism, habit, leaf -form, and flower colour in Primula sinensis, seed characters of Pisum, reduc- tion-division in Ferns, forms of flowers in Valeriana, and other subjects." In Nature for Dec. 12 Prof. Bateson deals more fully with Gregory's work, paying a high tribute to its special interest ; he left a mass of material which it is hoped will be published. The Botanical Magazine for Oct. -Dec. contains a figure (t. 8783) and description of Mesemhryanthemum edule L. "from material obtained by Mr. J. Hutchinson on the face of an old quarry at the entrance to Caerthiilian Valley in Cornwall, where it is thoroughly n.aturalized in compan}?- with the Australian and Chilian species M. cequilaterale Haw." The latter is entered by Davey from several places in Cornwall (Fl. Cornw. 204), but the former is not recorded by him. Mr, H. W. Moxcktox has prepared for private distribution a nicely-printed little book on The Flora of the District of the Thames Valley Drift between 3Iaidfi7ihead and London — on lines similar to those of The Flora of the Bagshot District noticed in this Journal for 191G, p. 9."). The idea of these geological district floras is to take 48 THE JOURNAL OF BOTA>V a satisfactoiT and in a way tolerably complete area of a single geolo- gical formation and to make a complete flora for it : in a way this has been done in Brewer's Flora of Surret/ and in W. II. Linton's Flora of Derh 1/ shire, but in both of these cases the geological areas are hampered by the county boundary. An interesting introduction describes the limits and geological formations of the district dealt with : the author has noted in the list the plants which have been found fossil in the neighbourhood of London, as it is of interest to compare them with the existing flora. The number and species enumerated (including the ferns) is 1308. The author's address is Whitecairn, Wellington College Station, Berks. The Kew Bulletin (Xo. 9) published in December contains the first instalment of " Contributions to the Flora of Macedonia," by W. B. Turrill, based on collections made by the writer and by others in their spare time by men engaged in active service with the British Salonika Forces. Paliurus microcarpus and Calami iifha epilosa, described by Mr. Wilmott in this Journal for 1918, p. 115, find no place in the list, which contains a description of a new Diantlius (D. Harrisii) and some interesting notes, including one on Trifoliiim snhterraneum. No. 10 (issued in the same month) contains letters from Charles Ogilvie Farquharson, who had held the post of mycologist in Southern Nigeria since 1911, was drowned on his homeward voyage on the 'Burutu,' which was lost tlu'ough collision. Mr. W. G. Craig continues his " Contributions to the Flora of Siam," which include a new genus Damron(jia Kerr (Gesneracciii-Didymocarpea)) "named in honour of Prince Damrong, who, himself interested in scientific pursuits, has done so much for the advancement of education in the country." The Keport for 1917 of " The Botanical Society and Exchange Club of the British Islands " consists of two parts — the first by the Secretary, Mr. G. C. Druce, the second b3^the Editor and Distributor, Mr. C. E. Britton. Of the former, *• on the salient features of British Botany," the author says : " This being his own compilation in no way assumes to express other than individual opinion, but all rights in its publication are reserved." No copy of either part has reached us for notice ; our readers may, howev^er, like to know that besides the usual notes of unequal value on individual plants, there are " Notes on British Violets," by Mi's. Gregory, "Notes on British Orchids," by Mr. Druce, and a " Kevislon of the British species of Sacjina,^'' by Mr, F. N. Williams. Perhaps the most remarkable feature of the Ileport is the entire omission of any reference to the existence of this Journal, which for fifty-six years has had some claim to be regarded as one of "the salient features of British Botany." It would be affectation to pretend to regard the omission as accidental ; but, from the scientific stand|)oint it is regrettable that the "individual" action of the Secretary of a Society, who is a])parently its only official, should deprive its membei's of the knowledge of what has been published in a Journal especially devoted to the science in which they are interested. The Watson Botanical Exchange Club would seem to be also under Mr. Druce's boycott, as although its name appears its Report is not mentioned. THE GENUS MANETTIA 25 23. M. CAXESCEXS K Schum., in Mart.

Lygistum\ see historical introduction, supra). According to Alexander the flowers are " deep blue." It is essentially a West Indian species, and is distinguished from its allies by the manifestly apiculate stipules, the nearly orbicular leaves, and the narrow, rather elongated calyx-lobes, curling and more or less setaceous at the tip. K. Schumann, in the Flora Brasiliensis, treats several of these allied species as varieties of M. Lygisfum ; but theiv characters seem well worthy of the specific rank to which Sprague (Bull. Soc. Herb. Boiss. ii. v. (1905)) has assigned several of them; among these the latter author has properly recalled Willdenow's M. pi eta (JLT. alba., infra), a native of Guiana. 36. M.

Peru & Chili, i. 58. t. 90. f. a (1798). I was inclined at first to identify with this species a plant collected by Pearce, in agreement with Sprague's MS. in the Kew herbarium. But comj^arison with the descrij^tion, and with the figure quoted above, leave no doubt that this plant is distinct. According to the authors, JSL umhellata is a native of woods in the neighbourhood of Muna, in Peru, flowering in the late autumn. It has ovate, si:b- eordate leaves : the bracts form a distinct involucre to the umbellate inflorescence, which, according to the figure, has a decidedly stout ^/°f/w?2c/e and primary branches ; the cf^/ya%lobes are lanceolate; and the corolla-twhQ cylindi'ical, not widened at all toward the aj^ex.

Bot. 1918, p. 152.) Ii^ the present notes seven new species o£ Sedum are described, and three new varieties. The new species, which are all based on living material, are derived mostly from an interesting packet of seed received from the Rev. E. E. Maire in 1915, collected by him about Tong-tchouan, in Yunnan. These seeds germinated, producing nine species, and it is indicative of the great richness of the Yunnan 6Vf/««i-flora that, despite the large number of new species described from that area in recent years, four of these were new. The remaining species represented were S. Celled K. Hamet and H. Le- hlancoB H. Hamet, both described from sjDecimens in the Paris Her- barium, collected in Yunnan b}^ Delavay ; S. yunnaneuse Franchet var. valerianoides II. Hamet (section Pseitdorhodiola Diels), an interesting plant evidently common in Yunnan (see Notes from R. Bot. Gard. Edinb. viii. 139 et seq.) ; S. trijidum Wallich, a familiar Himalayan species of the Waodiola section, not reported previously from China (the plants recorded as varieties of S. trijidum in Notes R. Bot. Gard. Edinb. v. 119, vii. 7, 11, 19, 181, 293, belong to 8. linearijolium Koyle (see Notes, vii. 399)) ; and the variable S. indi- cutnR. Hamet {Crassula indica Decne) in several different forms, of which one is now described as new. Of the remaining new species, one comes from Bhutan, a plant of the well-marked Rhodiola section, which has its head-quarters in the Himalaya- Yunnan region ; another from California, where it reinforces the spathulifoliurn group of N.W. North America ; and the last is a plant from a garden source, allied to the group just mentioned, and probably collected in British Columbia. The new species will be figured later in the Journal of the Royal Horticultural Society. Section Rhodiola, Series Rhodiola sensu stricto. ^ Sedum Cooperi, sp. nov.

The description is taken from specimens which flowered at Glasnevin and in my own garden in 1918. When the leaves are pseudo-ternate the plant somewhat resembles a slender >S'. yunnanense Franchet, but the inflorescence is totally different. Section Rhodiola, Series Crassipedes. Sedum cbassipes Wall. var. nov. cholaense. A very robust and distinct variety was received, in the form of either roots or seeds, from Darjeeling and Edinburgh Botanic Gardens and from Lissadell Nursery. All appear to have had a common origin — the Chola Valley, East Sikkim, where the plant was collected hj Cooper (no. 923). The unusual dimensions of the parts of the plant, coupled with its flowers, wholly' green save for their conspicuous crimson scales, give it a ver}^ distinct appearance. Typo robustior.

I have grown a large series : apart from very large forms, botli hairy and glabrous, wliich may be placed under sub-var. macropliyllum Kouy Si Camus, the most distinct is a plant distributed by F. Siindermann, of Lindau, under the name S. rivulare (but S. rivulare Boissier = aS. melanantherum DC, a quite different plant). It was collected by Siindermann in Spain — NOTES OX SEDUM 51 I believe in the Sierra Nevada, but the locality is not stated in his Catalogue (for 1913), and the finder is not at present accessible.

Maire from Tong-Tchouan, 2900 metres, in 1915. The plants flowered, one in October, 1916, and the rest in August, 1917. They died in the autumn of 1917, but 1 think this was probably due to over-flowering rather than to a natural biennial duration of the plant. From the other species of Sedum of the large series Joponica which have also relatively broad leaves (ovate or spathulate) and yellow flowers, S. Mairei may be distinguished as follows: — *S'. Alfredi Hance has ligulate (not ovate) petals three times (not slightly) longer than the sepals, rotund-truncate (not cordate-stipitate) scales, and carpels connate half way up (not nearly free). S. Dugueyi R. Hamet is a minute plant with tiny crowded ovate- deltoid leaves. >S'. Q-iajai R. Hamet is a small hairy plant, with leaves only ^ inch long. S. Moroti R. Hamet has blunt spurred obovate sepals, oblong- hnear petals, terete scales. *S^. Schoenlandi R. Hamet is easily separated b}^ its hairy leaves, racemose inflorescence, and the presence of only five stamens. S. Someni R. Hamet has only five stamens, and is described as annual. In some respects it appears to resemble S. Mairei^ but it has sepals entire and very obtuse at the apex (not papillate-margined and apiculate), petals " subsemioblong " subactate, widest above the middle 54 THE JOUnXAL OF BOTANY (not ovate, acuminate, widest one-third way up), and scales with the limb twice as broad as long (not as broad as long).

The flowers of the batch of plants raised showed a variety of colour unusual in Sedum. The petals varied from pale straw-yellow to deep orange, and in some the stamens and inner face of the carpels were crimson, and the scales flushed with red. The plant takes its name from this circumstance. Section Semperviyotdes, Series Sempervivoides sensu stricto. Sedum indicum a. Hamet {Crassula indica Decne ; Sedum pani- culatum Wall.). A packet of seed sent in 1915 by Pere E. E. Maire produced a crop of Sempervivum-like plants which displayed great variation in all their parts — leaves, stem, inflorescence, and all portions of the flower — as regards form, texture, and colour. The range of variation was greater, for instance, than that found among the British fruticose Kubi ; but nevertheless it seems best to retain all under S. iiidicum as variants of a single polymorphic species, bestowing varietal rank on the mcst distinct undescribed departure from what may be taken as the type. The species is a biennial, producing in the first year a leaf -rosette closely resembling those of some of the European Sempervivums (and found occasionally among Sedums, as in S. sempervivoides Fisch. and its allies from the Caucasus region, and S. orichalcum W. W. Sm. from Yunnan). From the centre of the rosette is pro- duced in the second year a leafy simple or branched flower-stem bearing a large paniculate inflorescence of small whitish or reddish flowers, with five erect free petals and live stamens. 5(3 THE .TOUK>'AL OF BOTANY No diagnosis is attached to Wallich's name {List, no. 7227). Decaisne's description (in Jacquemont's Voyage dans VInde, iv. 61) is tolerably full, and most of the dried specimens which I have had an opportunity of examining agree fairly satisfactorily with it. The majority of the plants raised from Maire's seed may be referred to the same form, which may be taken as the type — plant glabrous, rosettes lax, leaves Hat, alternate, spathulate, acuminate, stem 4-10 inches. The only differences of any moment between my series of the t^^pical plant and Decaisne's description are that he describes the petals as lanceolate, subattenuate, and twice as long as the sepals, and his figure shows a campanulate flower with the tips of the petals tapering and erect ; in my series the petals were oblong or oblong- lanceolate with recurved tips, and the flowers resembled in shape those of the lil3^-of -the- valley. C. B. Clarke's description (Fl. Brit. Ind. ii. 413) is veiy short ; he describes the petals as " dull rose, scarcely twice the sepals." The tips of the petals are erect in bud, and also after flowering, and tend to assume that position in drWng ; this no doubt accounts for the absence in all the descriptions of reference to their character- istic reflexed habit. A peculiar thickening on the upper part of the face of the fleshy j^etals is likewise undescribed, doubtless because in dried specimens it is obscure. This is a marked feature of the type as represented by Maire's plants. In longitudinal section the S-shaped petal is seen to increase in thickness from the tip to half way down, when it contracts abruptly to about one-third of its maximum thic'k- ness, and continues so to the base, the scale occupying the hollow thus formed. In front view the thickened portion shows a bluntly bilobed lower edge. Two varieties have been described — var. Forresfi E. Hamet (in Notes R. Bot. Grard. Edinb. v. 115; type in Herb. Edinb.), a tall green plant with very broad ovate-suborbicular acute leaves, of which all but the uppermost are opposite; and var. yunnanense R. Hamet (in Journ. de Bot. x. 284 — Crassula yimnanensis Franchet) a densely hair}^ form with mucronate leaves. A number of Maire's seedlings are referable to this latter variety, of which I am able to amplify the description ; it is a noteworthy form, almost worthy of specific rank. Franchet separated it from Crassnia indica Decne mainly on account of its general pilosity and its mucronate leaves. In my plants the size of stem, leaf, and inflorescence was much less than in my plants of the type (Franchet says "Port et dimensions de C. indica"'). The leaves were very thick, being so convex on the under side that the breadth was only from once to twice the thickness, not thi-ee to four times the thickness as in the type. Flowers rather larger than in type, calyx narrower, petals more erect at base, so that the cor(.)lla is narrower, and less reflexed at apex, making the whole petal much sti-aighter ; the peculiar thickening of the upper half of the petal, which is so marked a feature of the type, is quite absent. The whole plant, as stated by Franchet, is shortly i)ilose, even to the backs of the petals. Another form deserving of varietal rank ap])eared in some numbers among the plants grown from Maire's seed. This was very unifoim xoTES ON sedum: 57 in character, forming dense glaucous (not lax glabrous) rosettes closely resembling those of Sempervivum calcareum Jord. and verv^ short flower-stems, and having different petals. It may be defined as follows : — Var. DENSIROSULATUM, var. nov. Bosulce densse, duplo latiores quam longiores. Folia quam in typo minora (circa 25 mm. longa, 8 mm. lata, 3'5 mm. crassa), spathulata, acuminata, valde glauca, a pice purpurea. Crt2^//s brevior (5-7'5 cm.) a basiramosus. InUores- cetitia congesta, rotundata, 5 cm. longa, 5 cm. lata. Petala rectiora, parte superiore minus incrassata. Sq^iiamoe angustiores. In this variet}^ the rosettes are formed of twice at many leaves as in the type (in which, moreover, the breadth of the rosettes is usually no greater than the length). This and the marked glaucescence of the purple- tipped leaves give the plant a veiy distinct appearance. Series Cepcea sensu stricto. '^ Sedum viscosum, sp. nov.

The plant flowered at Kew, Griasnevin, and in my own garden in 1916 and 1917, behaving often as a biennial, but very likely normally annual in duration. In its short life-period, habit, hairiness, stalked flat leaves and long-stalked flowers it agrees with a number of Chinese species — mostly white- flowered — which group themselves round the European S.

William Baxter (1787-1871), as a capable and energetic young Scotchman, was appointed head-gardener or curator at the Oxford Botanic Garden in 1813, when twenty-five years of age. He received a small emolument from the University and lived in a small cottage (since enlarged) in the Gardens. He had the assistance of three labourers, and only the barest apologies for greenhouses ; the establish- ment of the Garden at this time is figured in Mr. Giinther's Oxford Gardens, p. 152. Much can be done with enthusiasm and five acres of land, and Baxter managed to grow from 40U0-5000 species of plants, though the work was often heart-beaking, owing to the inefticiency of the equipment, and the possibility of the garden being largely submerged in flood-time. In such damp and mildewed Baxter's ' British phae;n^ogamous botany ' 59 environment Baxter took particular interest in mosses and fungus diseases ; he was made an Associate of the Linnean Society in 18 17 : his Stirpes Gryptogamce Occoniensis was issued in 1825. Oxford Botany at this time was at its lowest ebb : Dr. H. Williams, who occupied the Chair in succession to Sibthorp, was also Kadcliife Libi-arian ; nothing is known of his botanical attainments ; the only accommodation at the Gardens consisted of a building, originally built for a conservatory, in the oldest sense of the term, and still utilized as the Botanic Library. At that time it contained the herbarium and the books of Sherard, Dillenius, and Sibthorp, and also functioned as lecture-room when there were any classes. What practical instruction there was was left solely in the hands of Baxter, and given orally and informally. Access to a good collection of all the older literature was an essential factor in Baxter's success, and after twenty years of uphill labour he conceived the idea of himself publishing a work on floral types, which would serve the purpose of an elementary introduction to the systematic botany of the day ; this to be issued on the lines of the subscription works, of the "coloured plate and one sheet of text " pattern, as seen in many standard works of the period, produced — like the Botanical Magazine — for "ladies, gentle- men, and gardeners " ; the work to be carried out by local talent, and produced as cheaply as possible. A trial part was issued as a prospectus in May, 1832, soliciting subscribers ; it contained two plates {Frltillaria and Tulipa) with no text, but with some letterpress on the cover : this part is curiously reviewed as the real thing in Paxton's Hort. Reg. i. p. 6o5 (1832). The price was to be a shilling coloured and sixpence plain : and the work was designed to run to two volumes on " Elementary Types," two on Oxford genera, and two on the remaining genera of the British Flora, at an estimate of 500 or so. The labour of getting drawings in hand proceeded throughout the summer of 1832, and the first full parts were issued in September : each part was to contain four plates, with sheets of text, filled on both sides — and the work to continue steadily at the rate of a part per month. The issue was continued on these lines, and maintained with uniform output to the end of the series — ten years later; the total expenses averaged £300 each year. The cover was inscribed : — " British, Flowering Plants, drawn from Nature, and engraved under the direction of William Baxter, A.L.S.. F.H.S., etc., Curator of the Oxford Botanic Garden^ The first plate was the Fritillary, abundant and well-known as " Snakes' Heads " at Oxford, which with the second plate, the Yellow Wild Tulip, are still admirably adapted as the simplest types of floral organization for a beginner to study : the other two plates represented the Avens and the Sweet Violet. The' first plates Avere not particu- larly well-drawn, and were poorly coloured ; in fact, the plain copies of the earlier figures are more satisfactory than the coloured ones ; but essential details were figured separately, and the text was collated from the general run of contemporary floras (Smith, Curtis, Hooker, Withering, etc.) without any special originality beyond local records and stations. At a later date (1837) the covers were inscribed : — " Figures and 60 THE JOUllXAL OF BOTANV Descriptions of the Genei'a of British Flowering Plants, with the Specified English Names, Linnseaii Class and Order, Natural Order, Generic and Specific Characters, and References to the most popular Botanical Works, Localities, Time of Flowering, and Dissections showing the essential characters. William Baxter, F.H.S., A.L. and M.B.S." This applies to the extension beyond the first two volumes ; and the price (possibly increased to other than the original subscribers) is given as, coloured 1/6, plain 1/- (Loudon's Gard. Mag. iii. p. 606.) After the issue of twenty numbers, comprising eighty plates, by March 1834, these parts were issued as a completed volume, to which a preface (dated Feb. 2o, 1834) is appended, explaining the object and scope of the work, and expressing gratitude for support already experienced. The full titlepage is now headed: — "British Phaeno- gamous Botany, or Figures and Descriptions of the Genera of British Flowering Plants, by W. Baxter, A.L.S., F.H.S. , &c.. Curator of the Oxford Botanic Garden, Oxford (Parker) ; Published by jbhe Author." (The term Phaenogamous (cf, Lindle3^'s Synopsis (1828) is used in contradistinction to his previous issue of Cryptogamce Oxoniensis.) The plates in the first volume are mostly rather poor ; the majority are neither signed nor dated, and the work was distinctly an amateur production. The first plate dated is Jan. 1833 ; some of the earlier figures were touched up, revised, dated, and sometimes redrawn in later reprints, and so appear in the completed volumes, the revised ones being dated 1833. It is significant that Dr. Daubeny was appointed Professor of Botan}^ on Feb. 8th, 1834, and botanical matters began immediately to improve ; but whatever assistance Baxter may have had subsequently, he had got started and well on with the work, on his original lines, entirely on his own initiative. The financial side of the venture was in the hands of Parker, the well- known Oxford bookseller, who also attended to the disposal of the copies. The work was pnnted by King, of St. Clements, near the Gardens, and the figures were drawn by local artists. Isaac Russell, an Oxford glass-painter, drew over 200, and was entrusted with the best coloured figures ; C. Matthews drew another 200, including all the Grasses and Sedges, as also inconspicuously coloured ones (Umbel- liferaj, small Crucifene, 'AL OF BOTANY but a small affair, had not been as yet appreciated b}^ British botanists, and broad generalizations were still wanting. To cut the types down to one per order, in the manner of Daniel Oliver (Lessons in Elemen- tary Botany, 1864: Illustrations of the Principal Natural Orders of the Vegetable Ki7igdom, Oliver and Fitch, 1874 — 102 Flowering Plants, plain or coloured), was the next stage of more strictly educa- tional work ; but Baxter deserves to be credited with the first step, made under conditions of minimum equipment. Many of the figures attain a high order of merit, those by Russell being the more elegant in design ; many British weeds are beyond much decorative treatment ; as examples of the work at its best mav be noted RusselFs figures of Glaucium (131), Caltha (153), Foxglove (113), Columbine (221), Linnaea (340), Rubia (185), Inula (265), Cyclamen (505) ; or the Hop (342), Ash (382), Martagon (501) of Matthews. Much of the coloured work is an improvement on Sowerby's JEnylish Botany ; the more detailed dissections and schemes of floral pai-ts are often extremely good (cf. Lemna (424)^ Alnus (193), Carpinvs (234), Oak (371), Castanea (485) : these, though small, are preferable to the coarse work of Fitch in Oliver's types of orders, and are on a plane quite different from the current issue of The Camhridge British Flora. The text presents no special novelty beyond local records, being a compilation from existing literature ; but it undoubtedly packs far more into the regulation two pages than any other flora, and is still useful as a store-house of odd points of interest culled from ancient liteniture. Older reviews of the work state the same facts : " The plates equal in excellence to any that have been published, and the letter-press far superior to that of most British Floras" (Loudon. 1835) ; "One can hardly name a more suitable present for a young person " (Gard. Chron. 1843). Above all the work was distinctly cheap and of honest value : cf. Maund's Botanic Garden, 4 coloured plates (small) 1/G a month : Sowerby's English Botany, cheap-edition, 2/- a month : Curtis's Botanical Magazine, 8 plates, 3/6 a month : the Botanical Register, 8 plates, 4/- a month : Paxton's Magazine of Botany, 8 plates, 5/- a month. The special character of the work is its steady output, continued over a number of years on the part of quite a few people ; as the product of a small university town, it in many respects runs parallel with the sixteenth-century work of Fuchs and his men. Baxter's draughtsmen were similarly non-botanical artists to begin with, and the improvement in their work is very marked. Many of the plants are identical, and it is interesting to compare the similarity of treatment — e. g.. Strawberry, Iris, Oxalis, Coltsfoot, Dais3^ If the work does not appear more remarkable as a novelty in Botany, it is because the framework of the design was too rigorously based on the subscription -principle and the vogue of the day. The detailed description of a suitable series of types of common plants, in handy form, similarly arranged as a sequence through the families, is still a desideratum, apparently beyond the efforts of British Botany. Although not included in Prof. F. W. Oliver's The Makers of British Botany (1913), Baxter in common with many other worthy botanists (as Borrer, Dawson Turner, Greville) has a niche in its history and Baxter's ' British phaenogamous botais't ' 63 he did his share in advancing the science in a period of considerable depression.

By James Sauj^ders, A.L.S. The Mycetozoa occupy an anomalous position in the organic world, having sometimes been grouped with plants, at others with animals. This may be due to the changes of form through which tliey pass in accomplishing the metamorphoses associated with their life-history. In what may be regarded as the initial stage, they float in the atmosphere as microscopic spores. When these fall on decayed vegetation they eventually throw off their cell-walls and assume an amoeba-like condition. Those of the same species have apparently an affinity, and form masses, usually small, of motile plasmodium. This is the assimilating stage, during which formative material is accumu- lated by ingestion. The circulation of these contents is singular and probably unique. The movement is a streaming which changes its direction at intervals of about two minutes. When it has assimilated sufficient material, sporangia are formed, each of which contains a number of spores often running into thousands. These are distributed by both organic and inorganic agencies, and again pass through a series of metamorphoses.

This species is named in honour of the late Hon. H. E. Cox, owner of the estate on which it was found. Also near P. speciosiis Jacq., but has somewhat larger flowers, the anther-cells united, a larger female disc, and styles united at the Phtllanthus latifolius Sw. There has been some confusion with regard to this species. The specific name originated with Linnaeus (Mantissa 221, 1771), who gives a short diagnosis, but definitely refers to the description by Patrick Browne — " characterem generis ex hac specie Brownii." This can only refer to Phyllanthus no. 1 of Browne, which alone includes a floral description, Browne's species no. 2 containing only a specific diagnosis. From Browne's description it is evident that the disk in the female flower does not form a continuous ring or cup, but is reduced to minute glands equal in number with the sepals, which glands Browne describes as 5 very short stamens with subrotund anthers situate round the base of the ovary. A sheet in Herb. Banks (Herb. Mus. Brit.) with specimens from Jamaica from Masson and others, is written up by Swartz Xylopliylla latifolia, and is probably the plant on which Swartz's first reference to X. latifolia {Prodromus 28) is based. We regard this plant as conspecific with Browne's (i. e., X. latifolia L.). Swartz in his subsequent descriptions (Obs. Bot. 113, 1791, and Fl. Ind. Occ. 1109) evidently refers to the same species, as he describes the disk in the female flower as Browne does, and cites Browne's description. He also cites Plukenet's PhytograpJiia, t. 36. f. 7, and Sloane, Cat. 16 & Hist.- i. 80 ; there are good specimens from Sloane in Herb. Sloane which agree with the plant in Herb. Banks. In Fl. Ind. Occ. Swartz transfeiTed the species to Phyllanthus. G-risebach seems to have had a correct view of the species, as a specimen of McNab's in Herb. Edinburgh is wi'itten up by him as Phyllanthus latifolius. Mueller (DC. Prodr. xv. 2, 431) in describing P. latifolius Sw. refers to the female flower as having a deep cup-shaj^ed entire disk equal in height to the ovary. His description is based solely on a specimen from Swartz in the Stockholm Herbarium. We have not seen this specimen, but there is in Herb. Banks one collected by Swartz in Jamaica which he has named " Xylophylla latifolia var.," in which the female flowers have this cup-shaped disk. We regard this as a new species (P. Swartzii). Urban (Symb. Ant. iii. 290) has been misled by Mueller's description of the female flower, and has redescribed the original X. latifolia as a new species, P. isolepis. In the Linnean Herbarium there is a sheet with two specimens without flowers named in Solander's hand Phyllanthus Epiphyl- lanthus. Smith has written below the one on the left " Phyllanthus n. 2. Br." — this specimen is P. angustifolius Sw. : below the other he wrote "Ph. no. 1, Br."— this is P. latifolius Sw. Linnaeus 68 THE JOURNAL OF BOTx\NT probably received these specimens from Patrick Browne, but the usual indication in his handwriting is absent. PHTLLAXTHrs ULABELLUS, comb. nov. The plant described by Grisebach (Fl. Brit. W. Indies, 84<) as P. tremulus is identical with a specimen in the Linnaean Herbai-ium from Jamaica collected by Browne, named by Linnaeus Croton glahelhim^ and described by him in Amoen. v. 409. This necessitates a change of name. There are good specimens of the same species in Herb. Banks from Jamaica, collected by Wright, and from Philip Miller's Herbarium, named by Solander Croton (jlaheUum L. No fewer than three species have been included by Linnaeus under the name Croton (/laheJlum L. In order of date these are : — (1) C. (jlaheUam L. Syst. ed. 10, 1275 (May, June, 1759) based on Sloane, Jam. ii. t. 174. f. 1. The specimen is in Herb. Sloane, and is the plant generally known as Croton lucidus L., the' first description of which appears a few lines below on the same page of the Si/ste?na. C. glabellum L. Syst. is therefore a synonym of C. lucidus. (2) C. glaheJlum L. Amoen. v. 409 (1760), based on the specimen in Herb. Browne referred to above. (3) C. (jlahellum L. Sp. PI. ed. 2, 1425 (1763). LinnjBus's description is based on the plant of the Amodnitates to which a reference is given (i. e., Phyllanthus tremulus). But Linnaeus cites also Brown. Jam. 348, and Sloan. Jam. 139, Hist. ii. 30, t. 174, :ff. 3 & 4 (in error for f. 2). The Sloane specimen (in Herb. Mus. Brit.) is the plant generally known as C. glahellus, and Browne's description may refer to the same species. That Browne is not referring to the specimen in Herb. Browne subsequently named G. glahellum by Linnaeus is indicated by his reference to the plant as aromatic. Linnaeus considered Croton to be of the neuter gender and in- variably wrote glahellum. Securinega. Adelia Acidoton L. (Syst. ed. 10, 1298 (1759)) is based on Acidoton (Browne, Hist. Jam. 355), and is described in the Amodni- tates (v. 411, 383) ; there is a specimen in the Linnean Herbarium from Browne, named by Linnaeus. The plant in question is Securi- neaa Acidothamnus Muell. Arg. in DC. Prodr. xv. pt. 2,451 (1866), {Flueggea Acidothamnus Griseb. in Goett. Nachr. 164 (1865)). Grisebach (Fl. Brit. AV. Ind. 42) cites Browne's plant {Adelia Acidoton L.), which, however, he had not seen, under Acidocroton adelioides Griseb., a totally different plant. Mueller cites Acidoton Browne as a synonym of Securinega Acidothamnus^ but omits refer- ence to Adelia Acidoton L., which he refers to Acidocroton adelioides in his lists of excluded species under Ricinella (p. 732), and Bern- ardia (p. 924), but does not cite it later in his description of Acidocroton adelioides (p. 1042). The name of the species is therefore Securineoa Acidoton. SHORT NOTES 69 SHORT NOTES. Chara fragilis and C. delicatula. In Braun's account of the Characeae in Cobn's Krypt. Flor. Schles. (1876) Chara delicatula Agardli was treated as a species apart from C fragilis Desv., of which it had previously been generally regarded as a variety. In Braun and Nordstedt's Fragmente einer Monographie der Characeen (1882) it was treated as a subspecies, and this latter course was followed in the ninth edition of Babington's Manual. We have lately been examining a considerable number of specimens of the two plants, and the characters which separate them appear to us sufficiently important to warrant their being treated as distinct species. C. fragilis, using the name in the restricted sense, has only rudi- mentary stipulodes, the primary and secondary cortical-cells of equal size, and no apparent spine cells : C. delicatula has well-developed stipulodes of one or both series, the primary cortical-cells distinctly larger than, often twice the diameter of, the secondary cells, and spine-cells clearly discernible though usually only papilliform. It was not until some years after an attempt to work out the distribu- tion of the British Charophytes was begun, that the difference between the two sections of C. fragilis (sens, lat.) was appreciated; hence a number of the earlier records cannot be apportioned to either, and their separate distribution is therefore only imperfectly known. We shall be glad if British and Irish botanists will collect and examine specimens of any of these plants they may come across, wdth a view to comj^leting the record of their respective comital distri- butions.— J. Groa^es and G. R. Bullock- Webster. Impatiens glandulifera Boyle. This is not recorded in Prof. A. H. Trow's Flora of Glamorgan. It grows abundantly in the meadows on either side of the river Ely for a distance of two miles west from the village of Peterston. A specimen from that locality has been added to the National Herbarium at the Cardiff Museum. — P. Blount MOTT. JuNCUS EFEUSUS SPIRALIS (J. Bot. 1918, 358).

By Alfred J. Ewart, D.Sc, Ph.D., F.L.S., and Oliye B. Daties, M.Sc, with appendices by J. H. Maiden, F.B.S,, I.S.O., and by A. A. Hamilton and Edwin Cheel. Melbourne : McCarron, Bird & Co., 1917. Pp. viii, 287 : 24 plates. Although bearing date 1917, copies of this volume only reached England towards the end of last year. The title is in some respects a misnomer, inasmuch as some of the omitted species have hitherto been recorded onl}" from the Kimberley District or the country to the 70 THE JOURNAL OF BOTANY south and south-west comprised within the tropic. The reason for this would appear to be that Bentham in the Flora Austral iensis included all this country in the term ** North Australia," a fact some- times overlooked by the compilers. The publication may be welcomed as an incentive to further exploration of this, even now, little-known part of the island continent. Its value as a handy guide would have been increased if the help of some one having access to the London herbaria had been secured, as those herbaria contain a large number of records either not known to or not noticed by Bentham. Especially is this the case with Robert Brown's and Allan Cunningham's collections, which, in spite of more recent labours, still remain the most important and fruitful in this special field. Moreover, access to the types of those collectors would have obviated mistakes into which the compilers could scarcely have fallen had they been more fortunately circumstanced with regard to the old material in question. Although of necessity largely a compilation, the volume contains descriptions of new genera and species during the expedition by Gilruth and Spencer and the Barclay expedition, the dates of which are not stated. There are four new genera — two in Graminese (Spafha and Setosa), one in Caryophyllaceae (Bossittia), and one in CouYolvnlacesd (Carpentia) : all of Ewart's. The first two names (the former is not in the index) are in opposition to the Vienna Laws, which are unfortunateh^ ignored in other respects — e. g. the descrip- tions throughout are in English only, and are thus, by the Laws, not entitled to recognition. The novelties are illustrated hj twenty-seven plates, which, though useful, leave a good deal to be desired as to execution : the large Roman figures on some of them are unnecessarily aggressive. In its general get-up, indeed, the book is very unsatisfactory : we have seldom seen a volume in which the arrangement and typography offer so much ground for unfavourable criticism. The descriptions are given in clavis form, but the ordinary method by which the name of the species is separated from the description and brought out to the end of the line, the name itself being printed in different type from the text, is here ignored : the names are continuous with the text and the type is the same as that employed for it. Seeing that Bentham's Flora Australiensis must have been constantly in the hands of the compilers it seems almost incredible that the obvious convenience of its arrangement should have been ignored in favour of one for which nothing can be said. The resom'ces of typography have not been utilized, the important aid to clearness which is afforded b}- a judicious use of black t3'^pe — here reserved for the names of orders — has not been recognized, though almost every modern Flora illustrates its advantages. " The Flora of the Northern Territory " stands at the head of each page, which should be, as it is in all well-planned Floras, made a source of useful information. On the other hand, information is sometimes given which seems useless : of what gain can it be to those who use the book to know that for Panicum^ for example, fourteen generic names have been emploj'-ed ? The space thus occupied — which in the aggregate is considerable — would have been better employed in adding useful bibliographical references, which are conspicuously THE TLOHA OF THE NORTHERN TERRITORY 71 absent. Here, again, there is a curious absence of system : the names and authorities are usually all in roman t}^3e, but sometimes all in italics. There is no need to pursue a criticism which might be indefinitely extended, and which is undertaken in the hope that it may influence future publications from the same source ; but a word must be said as to the Appendix on the Myrtacese, contributed by Mr. Edwin Cheel, which, whether regarded from a literary or a botanical stand- point, seems to us equally remarkable. Melaleuca Leucadendron and its limitations or extensions present much room for differences of opinion, but we cannot think that Mr. Cheel's efforts will do much to elucidate the difficulties presented. Mr. Cheel's views on nomen- clature may be illustrated by a sentence which also indicates his litei-ary style : writing of Melaleuca Leucadendron var. coriacea (M. coriacea Poir.), he says : " I have not seen the original specimens named by Poiret, but have taken up his name for this variety as it seems to be appropriate, and will cause less confusion than would be the case if Cavanilles's name * quinquenervia ' was taken up as it should according to the rules of priority, owing to the fact of other varieties having five-nerves" (p. 297). Such entries as "coriacea, Poir, suppl. 3, 685 (non Salisb.), See. D.C., Prodr." and "var. angustifolia, Linn., Fil. and Pers. (1807) " are examples of citation which might easily be multiplied. BOOK-NOTES, NEWS, etc. At the meeting of the Linnean Society on Feb. 6, two papers were submitted by Mr. N. E. Brown. The first dealt with a new species of Lohostemon in the Linnean Herbarium, to which Mr. Brown's attention had been directed by Mr. Lacaita. The sheet was inscribed by Linnaeus Echium argentewrtiy but the plant could not be identified with any specimen of that species in the herbaria of the British Museum and Kew, or at the Cape: it is entirely different from E. argenteum Berg. {L. argenteus Buck), with which Linnaeus supposed it to be identical. The plant, localised by Linnaeus "montibus nigris " (Zwartberg) and collected at least 147 years ago, does not appear to have been found by any subsequent collector. In the second paper Mr. Brown described numerous old and new species of Mesemhryanthemum,^Yei2iCm^ the descriptions with a history of the genus from the time of Haworth, who published four accounts of the genus between 1794 and 1821. Haworth's descrij^tions, though mostly from plants cultivated by himself or at Kew, are often insufficient for determination : but a large number of his species are represented in the series of excellent coloured drawings by two young gardeners, George Bond and Thomas Duncannon, who were employed at Kew by Alton between 1822 and 1835 to draw plants cultivated there, and of whom some account will be found in The Garden for Jan. 24, 1880 — reprinted in the third Supplement to this Journal for 1912 (p. 14). The drawings, mostly by Bond (who was alive in 1880), number about 2000, of which about a fourth represent Mesemlry anthem U7n. 72 THE JOURNAL OF BOTANY The recently issued part of the Flora of Tropical Africa (vol. ix. part 2, " 1918 ") continues Dr. Stapf's monograph of the Andro- pogonece. The genus Andropogon is restricted on lines already laid down in the first part of the volume : a large number of the species formerly referred here are transfeiTcd to Hyparrlieiiia, here apparently first treated as a genus although it was adopted as a section by Hackel in his monograph. The name stands as '• [N. J.] Anderss. (name onh'), in Nov. Act. Soc. Scient. Upsal. Ser. 3, ii. 254 [1856] " ; it may, we think, be questioned whether it can claim recognition, as it stands only in synon3Tiiy : *^ Anthistiria Pseudo- Cymbaria Steud. = Est Hyparrhenia? sp." A new genus — Dyhowskia — is established for Andropogon Dyhowshii Franch. The species, of which a large proportion are new, are described at great length — many occujjy a page or more : it is not quite easy to see for whose benefit these minutety detailed descriptions, testifying as they do to the carefulness which characterizes Dr. Stapf's work, are intended, as the botanist will, we think, find sufficient for his purpose in the keys to the species, which are very full ; their extent must materially hinder the completion of the Flora, which was begun fifty years ago. "We presume that steps have been taken, as in the case of the Floras of Madras and Jamaica, to secure the validity of the new names by the publication of a Latin diagnosis, in accordance with Art. 3G of International Kules : we note that the adjectival form of names of persons is spelt with a small initial (see Ai*t. 26, Eec. 10). The contents of the Journal of Genetics (vol. viii. no. 1) issued January 22 are mainly botanical. They include papers "On tlie Origin of a Mutation in the Sweet Pea," by Prof. K. C. Punnett ; On Hybridization of some Species of Salix " conducted by S. Ikeno at Tokyo (with plate) ; and " Studies of Inheritance in the Japanese Convolvulus," b}' B. Miyazawa (with coloured plate). Science Progress for January contains a comprehensive summary of recent botanical research by Dr. E. J. Salisbury, the notices of plant physiology being contributed by Mr. Walter Smith. In the interests of the reader we venture again to call the attention of the editor, Sir Ronald Ross, to the singularly unhelpful and unilluminative headings of the right-hand pages, which with very little trouble might be made of great assistance to those who consult the Review. Botanical Abstracts is the title of a new botanical journal, which has been set on foot by American botanists to take the place of the Botanisches Centralblatt, which, for various reasons connected with the War, has become unsatisfactory. It will be conducted by an editorial board, the vanous sections being undertaken by specialists. We have received two numbers of the Bulletin of Scientific and Technical Societies, which is issued fortnightly at Burlington House at the cost of i5d. by the Conjoint Board of Scientific Societies. Each number contains a diary of meetings to be held in the fortnight succeeding its publication, with titles of the papers to be read at each and an indication of future meetings. Communications regarding it should be sent to Prof. R. A. Gregorv, 10 St. Martin's Street, W.C. 2. 73 MISCELLANEA BKYOLOGICA.— VI. By H. N. Dixot^, M.A., F.L.S. (Continued from Journ. Bot. 1916, p. 359.) Ch^tomiteium Deplanchei Duby, and its allies. Ghcetomitrium Geheehii was described by Brotherus in Oefv. af Finska Vet.-Soc. Foerh. xxxvii. 165 (1895), from Queensland and l^apua. It is there stated to be allied to C. torquescens Brj. Jav., C. depressum Mitt., and C. Deplancliei Duby. The di:fferentiating characters from these species are not mentioned. In the key to Ch(Btomitrium in the Miisci Brotherus makes the following distinctions : — Seta faintly papillose only near the summit; branches flattened ; leaves scarcely concave ... C. Deplancliei. Seta clearly papillose for some distance down- wards ; branches scarcely flattened ; leaves very { p j. -l-j. concave \ ri ^ z /.••' [ U. (jreheebii. C. Geheehii Broth, is recorded by Brotherus and Watts in the " Mosses of the New Hebrides " (Journ. Proc. Roy. Soc. N.S. Wales, xlix. 146), as collected by Bowie in Tongoa Santo (under the numbers 110 J and 177 in Herb. Watts), and a sterile specimen of this (No. 177) was sent me b}^ the Rev. W. W. Watts. I have also in my collection a specimen of what is clearly the same gathering (Tongoa Santo, leg. Bowie) sent me by Mr. G. Webster (No. 581) : this is in fruit, and comparison with the description of C. GeJieehii showed one or two distinct differences from that. G. Geheehii should have a seta of 1 cm., scaberulous throughout except at the base ; the capsule sub-horizontal, curved, and the leaf margin erect. The New Hebrides specimen showed setae considerably above 1 cm., reaching to 1"5 cm., scaberulous onl}^ at the apex; the capsule erect or nearly so, and practically symmetrical, not or scarcely curved ; while the leaves had the margin distinctly reflexed, especially near the apex, where the leaf is suddenly contracted in the curious way characteristic of several species of this genus. Correspondence with Rev. W. W. Watts established the fact that these differences existed in his specimens also, and it seemed clear that the New Hebrides plant represented an allied but distinct species, probably new. Mr. Watts consulted Dr. Brotherus on the matter, but communications were entirely cut off by the war, and have not yet been re-opened. Before describing it as new, I thought it necessary to compare the allied Oceanic species, especially C. tahitense (Sull.) and C De- plancliei Duby. A sterile specimen of C. tahitense at Kew showed a very similar plant, but with the leaves much shorter and more shortly acuminate and less contracted below the apex, and the margin very little reflexed. I then examined C. Deplanchei in the British Museum collection. The specimen in Herb. Hampe showed leaves almost exactly like JouENAL or BotjlNt. — Vol. 57. [Apeil, 1919.] h 74 THE JOURNAL OF BOTANT those of C. taliitensfiy and differed also from Bowie's New Hebrides plant in the pericha^tial leaves narrower, more plicate, and with the apex still more remarkably ciliate-laciniate than they are there. The seta, just 2 cm. long, is finely papillose about half-way down, though faintly only. This appeared to show a distinct difference in both species as regards the leaves, from both C. Gelieehii and the New Hebrides plant, and in O. Deplancliei at least as regards also the fruiting characters. An examination of the specimens of C. Deplancliei in Bescherelle's herbarium, however, put an entirely different complexion on the matter. There ai'e several gatherings represented, of Deplanche's and Vieillard's, from Lifou or New Caledonia (the labelling " Nouv. Caledonie " in some cases and probably in all includes the Island of Lifou) ; and these, while clearly all belonging to the same species, showed a great and unexpected degree of variation. The seta varies from 1 cm. to 1*75 cm. on the same tuft ; the capsule is usually suberect and symmetrical, but may be, on the same plant, also decidedly inclined and curved ; the seta is usually papillose onl}'- near summit, but ma}^ be (as in Hampe's specimen) more or less papillose below. The leaf-point varies much in degree of acumination, &c., one specimen showing many leaves quite identical with Bowie's plant, while others approach very nearly the form and chai-acter of Hampe's specimen and C. taliitense. The perichaetial leaves also exhibit a good deal of variation in width, degree of plication, and in extent of ciliation. I do not find any marked difference in the concavity of the leaves between the various plants. There can be no question at all that both C. Gelieehii and the New Hebrides moss come within the range of C. Deplancliei. As to the position of G. taliitense^ I am not quite so clear. As far as the vegetative characters go, it might cei'tainly be identical with C. Deplancliei as represented by the plant in Hampe's herbarium. But Sullivant describes the perichaetial bracts as ciliate-dentate, and as ** very strongly papillose at back." In C. Deplancliei the outer bracts are papillose, and are moderately ciliate-dentate above ; the inner are smooth, and have the margins very strikingly fringed and lacerate with branched and re-branched cilia, frequently ending in a bi- or tri-cuspidate tip, reminding one of the processes of certain s[iecies of Staurastrum or similar Desmids. Sullivant's figure of the perichaetial bract of C. tahitense does not indicate any structure of the sort, and the description, ciliate-dentate, is somewhat ambiguous, If, however, the bract figured were an outer one, and the description of the dorsal papillae applied to that, it would represent very nearly an outer bract of G. Deplancliei. At the most, I think, even if the bract figured represented an inner one, the difference would hardly be sufficient for a specific character, especially bearing in mind the somewhat wide range exhibited b}^ the perichajtial bracts of the New Caledonian moss, and I suggest for it a varietal rank for the present, wliile fully anticipating that further examination of the fruiting plant may finally relegate it to the synonymy of C. Deplancliei. MISCELLANEA BBTOLOOICA 75 The synonymy will then stand thus : — Ch^tomitrium Depla:^chei (Besch.) Duby MS. e Jaeg. & Sauerb. Adumbr. ii. 273 (1875-6). Svn.

The Hyinenostoma and their allies of South Africa are difficult to grasp, and will probabty not be satisfactorily elucidated without an examination of C. Mueller's types at Berlin. One misconception may as well be cleared up, however. Eehmann issued No. 19, Musci Austr.-Afr. as Gymnostomum oranicum. C. Mueller published this in Hedwig. xxxviii. 112, as Weisia {Jlymenostominii) oranica Rehm., but makes no reference in his description to the capsule orifice beyond the terms " theca . . . microstoma . . . annulo nullo." On examination of Rehmann's No. 19, however (Bloemfontein, Orange Free State), I find a peristome distinctly present. The 16 teeth are very minute, very little exserted above the capsule mouth, and sometimes not at all, very narrow and pale ; but they are regular, articulate, linear, smooth and hyaline. It is therefore a true Weisia, not Hymenostomum. The dioicous inflorescence appears to be the principal chamcter by which it can be separated from W. viridula (L.). Ancectangium scabeum Broth. Among some mosses collected by Wm. Leighton in 1917 on Mt. Meru, German East Africa, at 5-6000 ft. altitude, sent to me for determination by Mr. T. R. Sim of Maritzburg, were two gather- ings of a minute Anoectangiuyn, one shorter and much more dense and compact, but both belonging to the same species. They agreed with the description of A. scabrtim Broth, precisely, and with an original specimen of Hoist's gathering at Kew ; they also agree with the description of A. 2ms ilium Mitt., with the sole exception that Mitten (in Journ. Linn. Soc, Bot. xxii. 305) describes his species, collected by Bishop Hannington on Kilimanjaro, as ** nerve dorso laevi," and notes "a small species, which agrees very nearly with A. Mariei, Besch., from Nossibe ; but the apices of the leaves are wider and their nerve is not papillose." h2 76 THE JOUENAL OF BOTANY Feeling some doubt as to the distinctness of the two, I asked Mrs. Britton to allow me to see a specimen of A. pusillum, and she kindly sent me part of the original gathering. As I rather expected, the nerve is distinctly, though finely scaberulous at back, and the plant is exactly identical wdth A. scahrum Broth. Mitten's mis- description is, I think, easily explained, while unfortunate. He compares his species with A. Ilariei Besch. Now A. Mariei, which according to Cardot (M. de Madagascar, p. 215) is identical with Barhula indica (Schwaeg.) Brid. {Tricliostomum orientale Willd.), is a species with the back of the nerve very highly and strongly scabrous or almost tuberculate, compared with which the nerve of A. picsillu?n might not mireasonably appear smooth. Smooth, how- ever, it is not, and Mitten's description of it as such has not un- naturally led Brotherus, in the absence of specimens (which existed only in Mitten's herbarium), to re-describe the plant as A. scahrum. A. scahrum must, however, fall into the synonymy of A. pusillum Mitt. Taxithelium gottscheanum (Hampe) Broth. Hampe (in Linnsea, 1874, p. 568) described this Philippine Is. species as Hypnum Gottscheanum. Subsequently he was led to suppose it to be identical with T. capillipes Broth. {H. capillipes Bry. Jav.), and he has corrected the labelling of all the three specimens in his herbarium to " H. capillipes " and " capillipes Bry. jav." I do not know that he ever published this correction, but even if he has not done so it may be well to remark that the identification is certainly erroneous. H. capillipes has the cells scarcely visibly papillose ; the papillae are so delicate, indeed, that they at first escaped the notice of the authors of the Bryologia Javanica, and it is only in a supple- mentary note on p. 228 that they add " Folia quam subtilissime punctulata, nee Isevia." The Philippines plant, on the other hand, has the leaf cells very distinctly, not to say highly, papillose, almost to the base, and it would be quite impossible for this to be overlooked, and Hampe's species may certainly stand. Hypnum scabrellum Lac. and its allies. Lacoste in the Bryologia Javanica described Hypnum scahrellum from sterile specimens collected by Korthals in Sumatra, and a Celebes specimen in theLeyden Herbarium ; adding " Floreset fructus ignoti." The inflorescence has been considered as probably dioicous. It is the Sematophyllum scahrellum of Par. Ind., but Cardot has shown good reason for considering it identical with the Samoan S. lamprophyllum of Mitten, a name which therefore has the priority. Beccari issued No. 37 of his *' Crittogame di Borneo," a fertile plant from Sarawak, as H. scahrellum; and Hampe, in describing Beccari's plants in Nuov. Giorn. Bot. ital. iv. 284, describes the fruit of this plant under that name. An examination of Beccari's plant, however, shows that it is not identical wdth Lacoste's species, and Hampe's description of the fruit must therefore not be taken as descriptive of *S'. scahrellum^ i. e. S. lamprophyllum, Beccari's plant, to begin MISCELLANEA BRTOLOGTCA 77 ^ith, is autoicous ; the leaves are considerably wider than in. S. lam- prophyllu^n, the alar cells are quite different, not indeed showing the characteristic inflated cells of Sematophyllum^ usually consisting of a single large inflated cell and several much smaller irregular thick- walled ones. The upper cells show regularly seriate, fine, acute papillae ; the perichsetial bracts also are markedly papillose. In view of the character of the alar cells, and the seriate papillae of the upper ones, I have little doubt that the plant is not a Sematophyllum, but a Trichosteleum. The fruit of the true S. lampropJiyllum is to be seen on the plant issued by Max Fleischer as Pungentella scahrella (Lac.) C. M., No. 389, Musci Frond. Archip. Ind. Ser. viii. from West Java. This agrees in habit, leaf-form, and basal cells with the H. scahrellum. The perichsetial leaves are comparatively short, erect, rigid, finely but shortly subulate, practically entire, and smooth. Seta about 1 cm., scaberulous above. No male flowers appear, the plant is undoubtedly dioicous. No. 5417, Perak, coll. Wray, in Herb. Mus. Brit., also appears to be the correct plant. In Journ. Linn. Soc, Bot. xliii. 321, I referred to S. lampro- pTiyllum (Mitt.), a plant of Rev. C. H. Binstead's from Borneo, Avhich, however, I find must also be considered distinct, as the fruiting characters do not agree with those of Fleischer's No. 389. Especially it is autoicous, and the perichsetial bracts are sharply and rather closely denticulate. It appears to be undescribed, and may be diag- noted as follows : — Sematophyllum decipiens Dixon, sp. no v. Habitu ;S'. lampro- pJiylli Mitt., sed paullo robustius, foliis latioribus, ovato-lanceolatis, concavis, marginibus erectis, acumine breviuscule subulato, denticu- lato. Autoicum.

The autoicous inflorescence removes it from the otherwise nearly allied species ; the denticulate perichaetial bracts also from >S'. lampro- phyllum ; the wider leaves from S. suhulatum (Hampe) ; the smooth seta, scaberulous cells and larger capsule from S. microthecium Broth. & Paris.

This agrees quite well with a New Guinea specimen determined by Mitten as his species. Fleischer has, however, pointed out that this species has been con- fused with T. tahitense Besch., a closely allied species with less glossy, shorter pointed leaves and quite distinct areolation. To this latter he refers Ceylonese specimens collected by himself ; and I find 78 THE JOUR?fAL OF BOTAIN^Y that both the New Guinea plant and Binstead's No. 304 from Ceylon must be referred there also *. p, 2S9. —Fterobri/opsis Walkeri Broth.

The New Zealand species of the Erythrocarpa and allied groups are very difficult, and present some very perplexing problems. I am looking forward — with no great appetite for the task — to attempting to solve these in the near future, and I have no intention of antici- pating that task now ; but one complication may be cleared away at once. Authors in dealing with the New Zealand Brya (Brotherus, Jaeger, Bescherelle, Paris, C. Mueller) have displayed much ingenuity in differentiating two plants, B. eryihrocarpoides Hampe & C. Mueller, and B. erythrocarpoides Schimp. For the latter Jaeger, followed by Paris, &c., has altered the rame to B. Bescherellei, to avoid duplication, while C. Mueller in Hedwig. xxxvii. 90 (1898), ignoring these authors, has quite unnecessarily re-christened it B. tornlosicollum. It does not appear that any of the authors concerned have taken the trouble to compare the two plants with one another, none ot' them at any rate make any comparison between them ; they appear to have assumed that, as Schimper saw a difference, it was " theirs not to reason why." The evidence for there being two distinct plants con- cerned does not therefore appear, ^r/wrt^/rrc/i?, to be very weighty, and what is to be said of it, when the fact is, so far as I can see, that Schimper himself never saw any difference between them ! Bescherelle (Flore Nouv. Caled. in Ann. vSc. Nat. 5 Ser. xviii. p. 214 (1873) describes B. erythrocarpoides Schimp. in herb, as a new species, based on New Zealand specimens ex herb. Schimper, leg. Knight, and New Caledonian ones leg. Krieger, 1866 ; and all subsequent authors have assumed this to be a different thing from B. erythrocarpoides Hampe & C. M. (1853). Bescherelle makes no reference to the earlier B. erythrocarpoides, and all the evidence goes to show he had overlooked it. No specimens of the New Caledonian ])lant are to be found in our collections, but Knight's plant, '* N.Z. 1867," the type of the supposed B. erythrocarpoides Schimp. is labelled by Schimper himself in his herbarium " B. erythrocarpoides Hpe. & C. M." The whole trouble seems to have arisen from a lapsus calami of Schimper, as the only New Zealand specimen in Bescherelle's herbarium is labelled *' B. erythrocarpoides Sch." [in Schimper's hand] " N. Zelande, Herb. Schimp." (in Bescherelle's hand) ; and this is identical with a specimen in the British Museum * Thdriot, I find, considers this plant distinct from T. tahitense, and names it T. Fleischeri, to which therefore all the above plants must be referred (c/. Bull, de I'Acad. Internationale de G^ogr. bot. 1910, p. 100). MISCELLANEA BBYOLOGICA 79 collection labelled in Schimper's own hand *' Bryum erythrocarpoides Hpe. & C. M., 156, N. Zealand [ex herb. Hpe.]." The bottom is therefore knocked out of B. Besclierellei Jaeg. Comparison of Knight's N.Z. plant and the original (Australian) B, erythrocarpoides Hampe & C. M. at first sight, it is true, suggests a difference, as the latter has rather wider, paler capsules with a quite obtuse lid, whereas the No. 156, N. Zealand has dark purple brown capsules with acute, apiculate lids, points which might constitute a difference ; but as the latter plant is labelled B. erythrocarpoides Hpe. & C. M., and is from Hampe's own herbarium, it is clear that both plants fall under the same species according to Hampe's own thinking. And further, New Zealand plants showing an intermediate form of lid occur in Schimper's herbarium as '' B, erythrocarpoides Hpe. & C. M., Tauranga, leg. Hutton, 1866." These have exactly conical, obtuse lids, and others highly convex and distinctly apiculate, on the same gathering, and show that Hampe and Schimper were quite right in uniting them under B. erythrocarpoides Hampe & C. M. A further difference might appear to consist in the inflorescence, as Bescherelle describes his " B. erythrocarpoides Scliimp." as synoicous, while all the other plants are dioicous. The New Zealand specimens on which Bescherelle bases his species (leg. Knight) are, however, certainly not synoicous, and it appears that Bescherelle was deceived in this respect \cf. Brotherus, 3Iusci, p. 589). In that case, B. ery thro car pulum CM., which according to the author is differen- tiated from Bescherelle's New Caledonian plant principally — probably entirely — on the ground of its dioicous inflorescence, must clearly fall into the same synonj^my. The matter may be summed up thus : — {a) there is no difference between B. erythrocarpoides Hampe & C. M. and B, erythrocar- poides Schimp, ; {h) Schimper never supposed there was any. The synonymy will then stand thus — with further synonyms probably to be added later : — Brtum eetthrocaepoides Hampe & C. M. in Linn. 495 (1853), Syn.

The plant is in fruit, and it differs notably from most species of the genus Barhella in the seta, which is longer than usual, and in the peristome. In most of the species the seta is only as long as the capsule, or 2-3 times as long ; in only two or three it is considerably longer {B. comes 3-5 mm., B. Kurzii (3 mm.). Here it is fully 10 mm., and sometimes 12 mm. long, thin, rugulose-papillose in the upper part. The peristome characters are still more marked, as the outer teeth are densely trans- versely striolate for a great part of their length, a character not hitherto found in Barhella, where they are at most striolate only near base. In view of tlie vegetative structure, however, this character is not sufficient, I think, to remove the plant to any other genus. "EPIPACTIS MEDIA (Fries!)" Bab. By Colonel M. J. Godfery, F.L.S. The history of the above name is very curious. Leighton says (Fl. Shropsh. p. 434, 1841) "Mr. Babington has directed my atten- tion to a plant which we gathered in 1835 in the woods on the west side of Bomere pool, and which we supposed at the time to be E. latifolia, but which he has recently determined to be E. viridiflora Eeich.'" (Fl. Germ. Exc. p. 134, 1830). He then quotes Babington's description, as follows : — " 2. E. viridijlora Reich. Leaves ovato- oblong, the upper ones lanceolate acute ; the lower bracteas longer than the flowers ; the terminal division of the lip triangular-cordate acute, as long as the lanceolate petals and sepals. Reich. Icon. f. 1142. Belch. Fl. Excurs. n. 891. Petermann, Fl. Lips. 641. Narrower and more elongated in all its parts than E. latifolia, only the lowest leaves ovate, the intermediate ones lanceolate, and the upper ones lanceolato-attenuated and merging gradually into the linear-lanceolate bracteas. Floivers ' green tinged with purple ' ; peduncle shorter than the downy ge.rmen. Lobe of the lip longer than broad, crenate. Woods at Bomere pool, Salop, and Luton, Kent." The above is practically identical with Babington's description of E. media Fries (Man. Brit. Bot. p. 295, 1843). It is clear, therefore, that he first considered the Bomere plant to be E. viridiflora Bchb., and later published it as E. media Fries. Tlie reason for this may be gathered from Leighton, who says, further on, " Fries (Nov. Mant. alt. p. 54) considers E. viridiflora Beich. as a variety ' floribus viridibus ' of his own E. media.''"' Fries, however, does not quite say this. He wrote "E. media (b) lloribus-viridibus lieich. ic. f. 1142, sec. Koch," He does not say that from personal observation he considered them the same, l)ut that, to judge from Koch, E. viridiflora is the same as his green -flowered media. I think we are justified in concluding that Fries did not personally know E. viridiflora, as, if he had done so, he would have given it as a synonym without qualifying it with the words "according to Koch." EPIPACTIS MEDIA 81 The fact that he did so qualify it shows that he was not sure of it from his own knowledge, and transferred the responsibility to Koch. Rouy tells us that E. viridijlora is often confused with the variety of atroruhens with yellowish green or green flowers (Fl. de France, vol. xiii. p. 204), and there can be no reasonable doubt that Fries intended his " 6. ^or^^z^s ^7^^^V/^6^^s " to refer to these green-flowered forms of his own JE. media. Koch names the latter E. latifolia /3. ruhiginosa (Syn. Fl. Germ, et Helv. pp. 694-5) and adds: — "Haec quoque occurrit floribus virentibus, ad quam E. viridijlora Rchb. ic. 9, f. 1142, et Serapias latifolia viridijlora Hoffm. referendae sunt." From this it is clear that he regarded Fries's (b) floribus viridibus as referring to green-flowered forms of E. atroruhens, and that he fell into the error mentioned by Rouy of confusing the latter with viridi- jlora. Koch evidently had not arrived at a final and considered opinion as to how many species existed in the genus Epipactis, for he gives atroruhens as a variety of E. latifolia, and admits that fm-ther observations are necessary to determine whether it is a distinct species or not. It is no matter of surprise, therefore, since he was confessedly unable of his own knowledge definitely to se^SiiixtQ E. atroruhens from E. latifolia as a species, that he was also unable to distinguish green- flowered forms of atroruhens from viridiflora, for, on account of their colour, the resemblance of both these latter plants to E. latifolia is more obvious than that of typical red-purple atroruhens itself. His attitude of mind was hesitating, but it is evident that he provisionally regarded latifolia, atroruhens, and viridijlora as one and the same species, and would thus be vevy likely to consider viridijlora as identical with green-flowered forms of atroruhens. Babington was clearer sighted, for he recognized both atroruhens and viridijlora as distinct species, but he unfortunately allowed himself to be misled by Koch, and, abandoning his correct identification of viridijlora, des- cribed the Bomere plant as E. media Fries. This error led on to another, for it blinded him to the fact that the true E. media Fries really did grow in England, and he actually described it as a new species under the name E. ovalis Babington. Fries himself tells us that his E. media " (c) floribus roseo-rubris " is identical with E. atroruhens, so that this fact is beyond dispute. I am much indebted to the kindness of Mr. R. F. Burton of Longner Hall, Salop, who, at my request, was good enough to explore the woods of Bomere pool, with a view to ascertain what species of Epipactis still grow there. He says : — " To-day (Aug. 15th, 1918) 1 walked over to Bomere pool and right round it, and round Shomere (about 300 yards this side of it). The chief plants, not counting trees, are sphagnum-patches, with nettles, Digitalis, Dog Mercury, blackberries, and bracken on the sides above the sphagnum, containing, as far as I could see, very few Orchidacese. I enclose the only samples of Epipactis in sight." Unfortunately, when these specimens arrived, the flowers were withered, owing to the heat, but on dissection, the position of the anther on the summit of a distinct stalk, its projection over the upper edge of the stigma, and the presence of a V-shaped incision in the wall of the column between the anther and the stigma, were visible, and these are the distin- 82 THE .TOUENAL OF BOTANT guishing characteristics of .SJ. viridijiora. As Mr. Burton found no other kinds of Epipactis at Boniere, and as Babington originally identified his Bomere plants as viridiflora, these facts may be re- garded as fairly conclusive proof that his original identification was correct. This is confirmed by Babington's description, which, as far as it goes, exactly fits E. viridiflora var. leptophylla (Journ. Bot. 1919, p. 39), with the exception of the words " flowers green tinged with purj^le." This is a very minor point ; Mr. Stephenson mentions that in his forma vectensis (Journ. Bot. 1918, p. 1) they are some- times so tinged, and they frequently are so on the Continent. The drawing of E. media in E. B. S. 2775, was made from a specimen of E. pnrpurata (E. violacea) (E. B. ed. ix. 124) from Woburn Abbey, Bedford. We have therefore this anomalous posi- tion— a plant identified as E. viridiflora Bchb. b}^ Babington was published by him as E. media Fries, and illustrated in E. B. by a drawing of E. violacea ! When the third edition of E. Bot. was published, the plates from the Supplement were embodied therein ; the reproduction of No. 2775, however, as I noticed at Kew, instead of adhering to the subdued colours of the original, was printed with bright reds and yellow^s, and is thus very far removed in appear- ance from E. violacea (which it originally represented) and suggests a much over-coloured E. latifolia. Perhaps it was partly due to this that the idea arose that Babington's E. media was a plant nearly resembling latifolia, but differing from it by longer and narrower leaves, and rugose, instead of smooth bosses on the lip. So we find it appearing in the 14th ed. of Hayward's Botanists^ PocJtet-hook, as HeUehorine latifolia c. media Druce. The same work recognises E. violacea as a separate species under the title 11. purpurata Diiice, so that it appears to have been overlooked that the E. B. S. plate of E. media was diuwn from a specimen of E. purpurata. In 1917 Mr. Druce, at my request, very kindly sent me two or three specimens of media. I was unable to detect any difference between them and E. latifolia, the ostensible one being that the bosses of the lip were rugose in media and smooth in latifolia. In his letter accompanying the specimens, Mr. Druce said : I think, however, the plicate-rugose bosses are not sufficiently distinctive characters to be of specific value." With this I entirely agree. In a wood near Eashing, Surrey, where only E. latifolia grows, rugose hunches were more common than smooth ones. The difference is a slight one — in the one the epidermis is ^\Tinkled, in the other it is sufficiently expanded to smooth out the wrinkles. It is curious to note how, in course of time, the name E. media, given by Babington to E. viridiflora, has become transferred to ordinary E. latifolia with rugose hunches. Fries in his Mantissa says of his E. media : "carina plicato-crenata, quo certissime differt a E. latifolia in qua .... carina non plicato crenata." Probably it was from this that the idea arose that Babington's media was separable from latifolia by its rugose hunches, and this was strengthened by the E. B. S. plate 2775, as pointed out above. To sum up, the plant which Babington described as E. media EPIPACTIS MEDIA 83 Fries, was in reality JE. viridijlora Heich., and the first record as a British plant is Leighton's, on the specimens found by him and Babington in 1S35. The subsequent application of the name E. media to specimens of E. latifolia with rugose bosses appears to have been founded on a misapprehension, and the term E. media should now disappear from British botany, except as a synonym of E. atroruhens. AQUATIC ANGIOSPERMS : The Sign^ificaxce or theie Ststematic Distribftiojt. By Agnes Arber, D.Sc, F.L.S. It is generally recognized that the primaeval forms of vegetable life were probably aquatic, and that it is only in the highly evolved group of the Seed Plants that a terrestrial habit has become firmly established. It follows that any aquatics met with among the Spermo- phytes must be regarded as descendants of terrestrial ancestors, which have reverted in some degree to the aquatic habits of their remote forbears. That this view is tenable, and that the Aquatic Angio- spernis cannot trace their ancestry in an unbroken aquatic line from some far away algal progenitor, is demonstrated b}^ the fact that their floral organs, in the vast majority of cases, belong to a decidedly terrestrial type. From a study of the mode of systematic distribution of aquatic families and species among the Angiosperms, cei-tain general conclu- sions may be deduced. The most obvious and striking feature is the relative paucity of hydrophytes, in comparison with terrestrial plants. Contrasted with those that live on land, the number of aquatic families is so small as to be almost negligible, and even when all the individual hydrophytic genera and species are added, the sum total is relatively insignificant. This result is, however, hardly surprising when we consider that the Phanerogams are essentially a terrestrial stock, and are distinguished from the Cryptogams by their aerial mode of pollination, which has won for them the freedom of the land. Under these circumstances, the reversion to aquatic life could hardly be expected to occur on any great scale. It must also be remembered that the entire area of the fresh waters of the globe is very small as compared with the land surfaces, and that thus the aquatic Angio- sperms occupy a much more restricted field than their terrestrial compeers. The mode of systematic distribution of aquatics among the Angiosperms shows every possible variety. Among the Dicotyledons there are cases in which only one species of a terrestrial genus is aquatic (e. g. Polygonum amphihium^, and others in which a number of species in a genus are h^'drophytic while some are terrestrial (e.g. Banunculus with its aquatic sub-genus Batrachium). Again, an entire genus of an otherwise terrestrial family may be aquatic (e. g. Hottonia among the Primulacese) , or several genera of family may be aquatic (e.g. Jussieua, Ludwigia, etc., among the Ona- 84 THE JOURNAL OF BOTANY graceae, and Limosella, Hydrotrichey etc., among the Scrophu- lariaceae). Finally, an entire family may be aquatic and contain no terrestrial forms (S'. asperrimum L. 1, 2. A garden stray.] — Mi/o- sotis C(Bspitosa Schultz. *1. Ponds near Poynton ; E.

The mosses and hepatics below were collected during the spring, summer, and autumn of 1917, in and around Ilfracombe and on Bi-aunton Burrows, which are in North Devonshire (v.c. 4). In compiling the following list, which contains eighteen new vice-comital rjcords, the arrangement and nomenclature of the Census Catalogue' of British Mosses (1907) and the Census Catalogue of British Jfepatics (1913) have been followed, and I am verv greatly indebted for kind assistance and notes to Messrs. H. N. Dixon, W. Ingham, H. H. Knight, W. E. Nicholson, and J. A. Wheldon. On the much fre- (j nented Capstone Hill at Ilfracombe perhaps the most common ni )sses are Grimmia maritima (conspicuous in fniit during the autumn and winter months), Trichostomum mutahile var. littorale and Zygodon Stirtoni, while Weisia verticillata groAvs in a rock cleft, and the rare Tortula atrovirens var. edentula is found in some (quantity at one place on the Parade ; upon Lantern Hill, near the harbour and in the heart of the town, the rare fruit of Zygodon Stir- toni is produced and Avell-marked plants of Tortula atrovirens var. edentula occur. Noteworthy additions to North Devon are the ILFRACOMBE MOSSES AN^D HEPATICS 95 mosses Grimmia suhsqitarrosa, Coscinodoii cribi^osus, Tortula atro^ virens var. edentula, Fleicrochcete squarrosa and B^^yum Warneum and the hepatics Biccia comnmtata and 3Ioerc'kia Flofowiana. Calcareous rocks appear on the coast to the east of Ilfracombe, and this is strongly reflected in the moss flora, Weisia verticillata, Tricliostomum crispulum, Brachythecmm glareosum and other cal- cicolous species making their appearance, while the hepatic Lopliozia turhinata, always indicative of lime, grows in sheets by the roadside, c.fr. = with fruit. * = new vice-comital record. Mosses. Pleicridium axillare Lind. Very sparingly around a puddle on the top of Windcutter Hill, near Lee ; this has been found between Stoke and Hartland, N. Devon, by Mr. Frank Savery. Dichodoiitium pellucidum Schp. Wet rocks in the rivulet on coast between Ilfmcombe and Lee, just before it falls down the cliffs ; also by a road runnel in the Chambercombe Valley. Dicranella varia Schp. forma. A rather curious plant grew on wet clay on the top of Windcutter Hill near Lee, which had the tinv erect capsules of D. rufescens with the leaves of D. varia. Mr. Knight wi'ote, " I was quite prepared to find that your Bicranella was rufescens until I examined the leaves under the microscope. They were certainly those of i). varia,'' and again he wrote, " The capsules are nearly erect, but the leaves in your plant have the margins narrowly revolute and entire and the narrow cells of varia. In rufescens the margins are plane, denticulate in upper part and cells larger. Bufescens is much less common than varia, though both here (Cheltenham) and in S. Wales I have not found it very uncommon." *Campylopiis frag His B. & S. In small quantity among grass near Mortehoe. — C. brevipilus B. & S. In small quantit}^ in one place on the coast between Mortehoe and Mortehoe Point, a J'oung state ; the hair-points were difficult to find. Bicranum BonjeaniT>e Not., forma. A very curious form which has been distributed through the Moss Exchange Club grew on thj thatch of an outhouse at Cheglinch, a hamlet near the village of West Down, Ilfracombe ; about it Mr. Dixon wrote : " I have never associated var. juniper if olium with the bright green soft habit of the B. Bonjeani you send ; it is usually rigid, dark brown or blackish, with rather rigid leaves. In the gene.i'al leaf direction, however, and cliaracter of leaves, it comes very near it. I should be inclined to call it a form, in some respects very near var. juniper if oliitm.''''— B. majus Turn. This fine species grew for nearly half a mile in a hedgebank bordering a wood about half a mile west of Bratton Fleming railway station with Blagiotliecium undulatum and Hylo- comium loreum, the three species fruiting very freely for a long distance. Grimmia maritima Turn. Occurred abundantly and fruited profusely on rocks on the coast to the west of Ilfi-acombe but was scarce or absent on the coast to the east of the town where the rocks are calcareous ; it was plentiful on Capstone Hill and also grew 90 THE .TOL'EXAL OF BOTANY on Lantern Hill, close to the harbour. — G. tricJiopliylla Grev. On Hillsborough and common along the coast to the west of Ilfracombe, sometimes very dwarf. — * G. suhsquari^osa Wils. In fair plenty on siliceous rock by the roadside at Upper Warcombe Farm between Lee and Mortehoe ; plentifully on a bank on the coast between Mortehoe and Woolacombe ; plentifully on rocks on the coast between Mortehoe village and Mortehoe Point. Mr. Dixon wrote: — "I think your Grimmia must be referred to the type form of G. suhsquarrosa. Var. edinensis is a very short, dense form — a starved state probably, just as G. Stirtoni is probably a starved state of G. trichopliylla T In 1910 Mr. G. Wrey found it fruiting near Torquay, in November 1917 I noticed it bearing capsules very sparingly on the coast near Mortehoe. Mr. F. Kilstone sent me from Polperro (v.c. 2) a plant about which Mr. Dixon wrote : — " Certainly one of the transitional forms connecting G. trichophylla and G. suhsquarrosa ; in some respects nearer the former, but the basal cells show a decided tendency to be of the suhsquarrosa form." Mr. Frank Savery found G. suh- squa7'rosa at Anstey's Cove nesti* Torqua}^ ; for its strange occurrence with other aberrant species on the Wiltshire sarsen stones near Marlborough, see Journ. Bot. 1916, 19. Rliacomitrium fasciculare Brid. Rock on coast between Ilfra- combe and Lee. — R. heterostichum Brid. Large tufts occurred on rock in Freshwater Bay between Ilfracombe and Lee {teste Dixon). — B. lanuginosum Brid. Mr. F. A. Brokenshire sent me this from near Shoulsbarrow Common on the edge of Exmoor. — R. canescens Brid. Damp ground by roadside near Spreacombe. *Coscinodon crihrosus Spruce. In some quantity on the west and eist sides of Freshwater Bay halfway betrvveen Ilfracombe and Lee; the fruit is not rare in June and July. Here it grows on three stone walls, as well as in places thickly encrusting the rock crevices ; it also occurs in seams on inaccessible perpendicular faces of the cliffs. Some of the cushions were very large ; the delicate pale green colour of this moss when wet contrasts strongly with the grey velvety mouse-skin-like appearance when dry. New to the South of England, the nearest station appearing to be in the Lake District; a Welsh locality near Barmouth is well known. Ptychomitrium poIyphyJJum Fiirn. c.fr. plentiful on walls in the Sterridge Valle}" ; also c.fr. on walls by roadside between Mullacott Cross and Ilfracombe. Pottia recta Mitt. c.fr. on bare ground by the sea near Mortehoe (Knir/ht). — P. intermedia Fiirnr. Bank by roadside between Mortehoe Ivailway Station and Woolacombe. — Tortula amhigua Angst!'. Bank near Ilfracombe. — T. aloides De Not. c.fr. bank on road between Ilfracombe and Combemartin ; also c.fr. bank between Woolacombe and Mortehoe. — T. atrovirens Lindb. Rather plentiful on the coast on banks between Woolacombe and Mortehoe ; also on clay on the coast near Saunton. Mr. Dixon referred to A^ar. edentula (B. & S.) Par. (1906) plants from Saunton and also from Capstone and Lantern Hills, Ilfracombe. Of the Saunton plants he wrote : — " Some of it is var. edentula and some is not. This shows the unsatisfactory status of the var." Of the Capstone Hill plants ^ ILFEACOMSE MOSSES AKD HEPATICS 97 he wrote : — " Your T. atromrens has the peristome very variable, but for the most pai-t considerably reduced, and I should place it under Tar. edentula.^'' Of the Lantern Hill plants he wrote : — " This is the extreme form of the var., and it is interesting to know that all forms exist in that locality from the almost gymnostomous to the well developed peristome." For an account of this see Journ. Bot. 1916^ 272. — T. Icevipila var. ladvipilcBformis Limpr. Fairly plentifully on trees by a small watercourse on the road between Watermouth Castle and Berrynarbor ; also on a tree near Watermouth Castle. Mr, Dixon writes : — '* Your T. Icevipila may certainly be referred to the var. as it has a marked border to the leaves as well as the foliose gemmae. I have frequently found it associated with T. papillosa, and am inclined to think that both prefer a larger amount of moisture than the noi-mal form of T. Icevipila, I suppose the var. Icevipilceformis may have a rather southern distribution ; it seems to become much commoner in the South both within Britain and also outside, but I am inclined to think it takes very little to turn the type into the var. ! " — T. ruraliformis Dixon. Abundant on Braunton Burrows, also plentiful on the Woolacombe dunes ; Mr. W. Watson of Taunton tells me it fruits on Braunton Burrows, and I noticed young setse at Woolacombe. Mr. Wheldon writes : — " An anomaly is that although T. ruraliformis is xerj abundant on our (Lancashire) dunes, it never fruits there now, although I believe it did so formerly, but on the Welsh coast it is not at all rare with capsules," The fruit occurs in fair quantity on the Burnham-on-Sea sandhills in Somerset (v.c. 6). (To be concluded.) BIBLIOaRAPHICAL NOTES. LXXV. " Madeira Flowers." Such jwints of interest as may be connected with the two books which form the subject of the following notice are perhaps literary rather than botanical : but as both volumes were thought sufficiently connected with botany to find a place in Pritzel's Thesaurus and Dr. Daydon Jackson's Index, and the authors are, in accordance with our rule, included in our Biographical Index ^ a note u}3on them may be worth printing. It is surely somewhat remarkable that two books by membei's of the same family living in the same island should be issued in the same year (1845) from the same printing and publishing house (Reeve Brothers), each similarly bound in green cloth with a floral •device in gold on the cover and differing only in size ; and that neither should contain any reference to the other ! Moreover, the object in publishing in each case was not dissimilar : Mrs. Penfold's Madeira Flowers, Fruits, and Ferns was produced " to gratify those :visitori5 and residents who take an interest in [Madeiran] productions " ; Mvs. Augusta J. Robley's Selection of Madeira Flowers (folio), " dedicated to her mother, Mrs. Jane Wallas Penfold," was " the humble offspring of a wish to gratify some friends who have kindly flattered me by thinking my paintings worthy of publication." 98 THE JOURJs^AL OF BOTAXT "Drawn and coloured from Natui'e " appears on the titlepage of each book, and the scientific descriptions in both are from the pen of the Eev. W. L. P. Garnons (tl863), then "of Sidney College, Cam- bridge," though the " local information " in the former was written by Mrs. Penfold. The plates in both books are well drawn, although, as might be expected, botanical details are wanting ; all were lithographed by the same hand (" R. E. B."). From a literary standpoint, Mrs. Penfold's quarto volume is the more ambitious production : it contains 20 plates, of which no lisb is given — Mrs. Robley's work is also deficient in this respect. "We learn from the preface (dated February, 1845) at her request wrote for the volume, two years before its publication, some verses (to which his autograph in facsimile is appended). These appear in Knight's edition of the Poetical Works of William Wordsworth (viii, 156) vaih. the following heading : " To A Lady " in answer to a request that I would write her a poem upon some drawings that she had made of flowers in the island of Madeira." I can find no reference to Mrs. Penfold in any Wordsworth biography, nor does it appear from her preface that she was acquainted with him. She remarks in her preface that " the flowers he names do not all correspond with those subsequently selected, and this indeed is the case, as they alluded to common British plants — heart's- ease, speedwell. star-of-Bethlehem and forget-me-not. It is fair to say that the Laureate confesses his unfitness for the task imposed on him : the poem begins :— " Fair Lad}^ ! can I sing of flowers That in Madeii'a bloom and fade, I, who ne'er sate within their bowers, Nor through their sunny lawns have straj^ed ? " " Much valuable assistance " is acknowledged from the Rev. R. T. Lowe (1802-74), who was at that time English chaplain in Madeira; for " the arrangement and description " of the ferns Mr, Henry "Webb — entered as "of Clapham " in the subscription list headed by two duchesses which is prefixed to the volume — was responsible. Mr. Garnons's descriptions are in Latin and English. Amaryllis Belladonna, the subject of the first plate, is also represented in a " vignette " preceding the titlepage, showing its habit of growth in October, '" completely covering the hills and valleys with [its] bright blossoms." Notliochlcena Marantce (t. iv.) which had been thought to be confined to one locality, was " found b}^ the writer among the mountains of the Alegria district, at the Arco de Calheta, and in the neighbourhood of the pretty village of Madelina : " Mrs. Penfold had property "at the Alegria" (see text to t. xv.). The only note of interest is that on Salvia splendens (t. x.), which " was introduced into Madeira by Mrs. Penfold of the Achada, and, from a small plant from England, it has been pro- pagated all over the island, so that it now forms the principal ornamental shrub in most cottage gardens. In some places hedges are made of this beautiful plant, which blossoms nearly through- *• MADEIRA FLOWERS " 09 out the whole year in such profusion that the eye can scarcely bear to rest on its brilliant colour. The Portuguese make a bright rose-coloured dye for articles of dress from the petals, and the renowned feather- flowers made by the nuns at Santa Clara Con- vent own (sic) much of their brilliancy to colours extracted from this flower." We learn from R. T. Lowe (Bot. Mag. t. 3296) that Mrs. Penfold imported seeds from Brazil in 1828, and that Cleome dendroides, the subject of the plate, was raised from such seeds. The drawing for this plate was by Miss M. Young, who con- tributed many figures of Madeira plants to Hooker for Bot. Mag. vol. Ixi. (1834) : she was a friend of Lowe (whose initials in this volume are often wrongly given as " J! T."), who expresses warm approval of her work, which is indeed of a far higher order than that of either of the ladies now under consideration : he does not mention either book in his Ifamcal Flora of Madeira. Mrs. Rob- ley's book, which marked her "debut as an artist,*' contains eight plates, th^ text of which I think was entirely supplied Ijy Mr. Garnons ; her own shary in the volume is confined to a brief preface (dated March, 1815) of eight lines. The text contains nothing of interest; it is noted that Htrelitzia (t. i.) was introduced into Madeira by Mrs. Pen- fold, from whose plant have been propagated all that are in the island. The plates show less artistic feeling than those in Mrs. Pen- foLl's book : t. vii, representing Liliicni camlidum and two Amaryl- lises, is very badly grouped. The books, copies of which are in the library of the Department of Botan}^, are apparently somewhat rare : neither is in the British Museum Catalogue and only the latter in that of Kew. Mrs. Robley's appears to be the less known, as it does not appear in the bibliography appended to the Flora do Archii^elago da Madeira of Senor C. A. de Menezes (Funchal, 1914) in which Mrs. Penf old's is entered. James Brittet^. P.S. — Thinking that some of the foregoing information might interest a wider circle than is reached by this Journal, I communi- cated it to The Times Literary Supplement (March 6) : the note there printed elicited one or two points of interest which may be appended here. Mr. A. L. Soper, of Messrs. Lovell Reeve & Co., tells me that both books appeared in the '* List of Scientific Works published by Reeve Brothers " issued in 1846, and that the price of each was a guinea. Mr. Gordon Wordsworth of The Stepping Stones, Ambleside — a grandson of the poet — writes that he possesses a copy of Madeira Flowers inscribed : " Wm. Wordsworth Esq'"^ from the Author " ; he has no information as to Mrs. Penfold's relations with his grandfather, so does not think they can have been intimate. Mrs. May^ of Ridge Hill. Macclesfield, tells me that the Wallases were an old Cumberland family settled near Penrith ; in the latter end of the eighteenth century one of them went to Madeira and entered the firm of Cossart, Gordon, & Co., and marriages took place between the families. Mrs. Penfold's second (? maiden) name being Wallas suggests that her request to Wordsworth may have been prompted by the recollection of an early friendship between her people and his. 100 THE JOURN.VL OF BOTANr SHORT NOTES. Pl^ltexei's References to the Flora. Loxdtnensts. Dr. B. D. Jackson and the late VV. A. Clarke have between them fairly well cleared up the chronological puzzles and the sequence of plates in the Flora Londinensis of Curtis. In Dr. Jackson's first note (Journ. Bot. 1881, 310) he refers to "a MS. of Pultenej seen by Mr. Pryor, but which I have not been able to verify." Mr. Clarke (Journ. Bot. 1895, 113) says that it "is, I believe, to be found in a copy of the first edition of Hudson's Fl. Anglica in the library of the Linnean Society." But neither he nor anyone else appears to have looked up the matter to verify it. In taking down this volume for some other reference, I noticed b}^ chance the so-called " MS. of Pulteney." It consists of eight lines (four in ink, and four in pencil) on the inside of the front cover of Pulteney 's own annotated copy of Hudson's work " ex Dono Authoris," afterwards owned by " Jno. Jones, Grray's Inn." The eight lines are as follows : — "The first no. of the Flora Londinensis was published in Maj' 1775. 'Jlie Plants of the Work are all marked in this Book with a C, as far as no. 67. No. 60 Nov. 1788 — 65 June 1791 — m June 1792 ? — 67 [no month'] 1793." Apparently therefore, 402 out of the whole number of 432 plates were issued from May 1775 to the end of 1793. "No. 60" of the MS. is quoted as " no. 59, in fasc. 5 " in Dr. Jackson's note, which is probably correct, as Clarke saj^s the numbering of plates ends with fasc. V, — not being carried on through fasc. vi., though some of the plates are dated. To what extent Pulteney's MS. Fl. Anglica in the Botanical Department of the Natural History Museum is based on his annotated copy of Hudson in the Linnean Library I do not know.— Frederic N. Williams. Plants in Flower at the End or December, 1918. — Several notes on this subject have appeared in various periodicals, and it may may be of interest to give some observations made in the neighbour- hood of Taunton, Somerset. On December 20th, whilst engaged in field-work amongst the bryophytes, I was so struck by the number of plants still llovvering that I made a list of those observed. This list during the remaining part of the year reached the surprising total of 73, and could have been considerably extended if specially secluded nooks had been explored, or if grasses, sedges, and other plants with inconspicuous flowers, had been examined more carefully. No sedges and only three grasses are included in the list. The weather had been very mild even for the west of England, and accounts for this large total. The plants found flowering fall into three groups : — (1) Those usually flowering in Somerset during this period ; (2) Spring plants which have had their times of flowering accelerated; (3) Late- flowering plants. In the first group the Gorse ( Vlex europceus) was the only one SHOET JfOTES 101 having a limited flowering- time. The other plants noticed are in flower with us at almost any period and include Caj)sella Bursa- pastoris, Gardamine hirsufa, G.Jiexuosa, Stellaria media (only with three or Ave stamens, the ten-stemmed S. ner/lecta is more limited in its flowering-period with us), Cerastium violgatum, Taraxacum offi- cinale^ Bellis iierennis, Senecio vulgaris^ Lamium purpureum^ Linaria Cymbalaria, and Poa annua. The spring flowers include Ranunculus Ficaria, Viola odoraia, Potentilla sterilis, Fefasites fragrans (apparently quite a wild plant in Somerset), Daphne Laureola, Mercurialis perennis, and Corglus Avellana. The Primrose must also be included here, though stragglers are often found flowering in secluded dells right through the winter months. A locality for the Snowdrop was visited, but no flov/ers were seen. The stragglers, or third group, include the following : — Ranunculus Flammula., R. repens, Sisymbrium officinale, S. Tlialianum, Lychnis dioica, Sfellaria Holostea, S. graminea (the former is not uncommon during mild winters, but the latter Avas a surprising find), Arenaria serpyllifoUa, Sagina procumhens, Reseda Luteola, Geranium Ro- bertianum, G. columhinum, 3Ialva sylvestris. several Ruhi, Geuni tirbanum, Spircea Ulmaria, Fragaria vesca, Vicia sepium, Hedera Helix, Chcerophyllum temulum, Anthriscus sylvestris (probably better placed in the second group), Senecio Jacobcea, S. erucifoliusy S. sylvaticus, S. squalidus (naturalized in Taunton and in flower from the end of April), S. aqaaticus, Chrysanthemum Farthenium, Achillea Millefolium, Crepis capillaris, Leontodon autumnale, Lapsana communis, Ficris hieracioides, Matricaria Chamomilla, Sonchus oleraceus, S. asper, Veronica persica {Fuxbaumii^, V. ar- vensis, V. Qhamcedrys, V. didy ma, Lamium album, Frunella vulgaris, Chenopodium album, Rumex conglomeratus, Euphorbia Feplus, E. exigua, and Factylis glomerata. — W. Watsois". PoTAMOGETON ACUTiFOLius Link. On p. 17 I gave the northern limit of this species as 60^ 12' N. lat., from Hagstrom's book. On checking these limits I find I have a specimen named as F. zos- terifolius Schum., from Finland — " Karelia Onogensis. Schunga. Aug. 1888. A. 0. Kihlman." This is 62° 30' N. lat. In Hjelt's- Consp. Fl. Fenn. 3, p. 540 (in Act. Soc. Fauna et Flora Fenn. v. 1895) P. zosterifolius is recorded from Schunga by Norrlin : this- is two degrees farther north, and records the species from Finland. Aethue BE:y?^ETT. New Yaeiett of Nitella elexilis. In 1884 a Nitella was discovered in Cambridgeshire by the late Alfred Fr^'^er, which, though monoecious, much resembled N. opaca in its dense fruiting heads, its large antheridia, and the more or less mucronate ti2:)s to the secondary branchlet rays. It was so markedly protandrous in character that when first collected, early in May, it had the appearance of being the male plant of a dioecious species. It was originally observed in the Old Bedford River at Sutton Gault, but was subsequently found to> occur in a number of stations in the adjacent fenlands of Cambridge- 102 THE JOUllNAL OF BOTANY shire and West Norfolk, and in one locality in Huntingdonshire. Specimens collected by Gr. E-. B.-W. in the original station and near Mepal in 1896, were circulated in Charac. Brit. Exsicc. No. 59, as a doubtful form of iV. Jiexilis var. nidijica. A further examination has led us to regard it as a distinct variety, for which, in honour of its discoverer, who did so much for the investigation of the aquatic plants of the Fen country, we propose the name of Var. Frteri. Perspicue protandra. Antheridium multo majus quam antheridium in typo, c. 800^ diametro. Verticilli fructificantes capita densa plus minusve formantes. Radii secondarii ssepe mucro- nati. Oogonia 660-745 /w longa, 550-610 yix lata, c. 500 /u crassa. Oellulaj spirales 6-7 convolutiones exhibentes et versus apices multo tumifacientes. Oospora 500-520 \x longa, 425-450 /u lata, 875 \x crassa, fusca-rubra aut fusca-rubida aut p?ene nigra, 5-6 strias promulas crassas exhibens sa^pe alis latis et conspicuis versus apicem. Membrana crassima et semirigida. In stature and habit this variety resembles N, opaca rather than N. fiexills. It is somewhat rigid and often much incrusted. A similar plant was collected by Wahlstedt and b}^ Olsson in 1864, at Lund in Sweden, and was distributed by the former in Nordstedt & Wahlstedt's Charac. Skand. Exsicc.

Gonijeroiis Trees jor Projit and Ornament : heinfj a concise descrip- tion oj each species and variety, witli the most recently approved nomenclature, list of synonyms^ and best methods oj' cultivation. By A. D. Webster. Constable & Co., pp. xx, 298, 28 plates. Price 21s. net. This is not the whole of Mr. Webster's title, as he has seen fit, in somewhat archaic fashion, to set forth the subjects of half-a-dozen of his chapters on the title-page. Although the preface starts oif with the enormous cost of our British imports of timber, the main subject of the book is the growth of ornamental conifers in this country ; and the illustrations, excellent as they are, show onl}'' young specimen trees. At the present period of paper-famine, a book has to justif}^ its appearance : it should, one might say, *' meet a felt want"; and we ai-e not sure either that there was need for '* a cheap, handy, and concise popular guide to hardy Conifers as cultivated in this country," or that (if such a want existed) Mr. Webster's book can be said to meet it. The late Mr. Kent's Manual oj the Coniferce, published for Messrs. Veitch, was, especially in its second edition, a fairly adequate, satisfactory, and, for its size, inexpensive work, and it is to be regretted that it should have gone out of print ; but at the present time more interest certainly attaches to the possibilities of the cultivation of a small number of species on a large scale for profit than to the merel}'- aesthetic requirements of the pinetum ; nor can the present work be considered "cheap" at a guinea. CONIFEROUS TREES FOR PROFIT AND ORNAMENT 103 It would be difficult for Mr. Webster or anybody else to over- estimate the indebtedness of the arts and manufactures to the ConifercB, but it is assuredly saying a little too much to include petroleum among their products (p. xv) ; per contra, Pinus Pinaster is omitted from the enumeration of turpentine-yielding species on p. xvi, whilst Mr. Webster's knowledge of the commercial position of the j)roducts of the group appears incomplete when he says that '' it is hardly likely that pine nuts will ever find much favour in this country." With reference to our present-day needs, a mis-statement of geological results which suggests '' Ai'aucaria and members of the pine family " as occurring *' in the Devonian and Carboniferous series " (p. xix) is of small moment ; nor, perhaps, is it of much con- sequence that Mr. Webster puts Ginlcgo in the Order Taxacecd ; but his speaking (p. 2) of the "fruit " of that Order, and of the "ovary" of Grymnosperms in general (p. 1), together with his particularising certain species of Pine as having two seeds at the base of each cone- scale, suggests an insufficient knowledge of the anatomy of these plants. The description of the foliage of Taxodium on p. 171 as " pinnate leaves . . . arranged in horizontal rows on each side of the midrib," is another illustration of the same thing. It may be doubted whether the author is justified in including the species of Torreya among hardy conifers ; and in some other cases anyone acquainted with the forms in cultivation may be inclined to doubt whether the descriptions, which are obviously taken from actual specimens, are correctl}^ assigned. Arboriculturists who favour Conifers for ornamental planting may find the remarks on the culti- vation of each species, by a man of Mr. Webster's long practical experience, of value ; and there are many interesting notes on par- ticular specimens, such as those of Collinson's planting at Mill Hill, scattered through the book, though more might have been done in this direction. The book is well got up ; but it is unfortunate that the name of the genus is not put at the head of each page, since on opening the volume in the middle of the series of C's, you may be in Cedrus^ Cryptomeria, Ciinninghamia, or Cupressus ; worse still, in the longer series of P's you do not know whether you are among Piceas or Pines. Gr. S. Boulger. BOOK-NOTES, NEWS, etc. The Gardens' Bulletin Straits Settlements (ii. nos. 3-4, 1918) contains an account by Mr. I. H. Burkill of the establishment and history of the Botanic Gardens, Singapore, with notes on Henry James Murton and Nathaniel Cantley (d. 1888) (1853-81), who preceded Mr. Ridley as Curators : an account of the Herbarium was published by Mr, Ridley in the Annual Report on the Gardens for 1889. In the Journal of the Straits Branch, R.A.S. (no. 79) Mr. Burkill has a note on the murder of James Motley, which occurred at Bangkal, Labuan, on May 1, 1859. The recently issued pai-ts of the North Ameiican Flora (Dec. 30, 1918) contain the conclusion of Axel Rydberg's monogmph of the liosacece (vol. xxii. pt. 6) with additions and corrections to the 104j the JOUllNAL OF EOTANT volume, and the first part (vol. xxxii. pt. 1) of the Buhiacece, by Paul Carpenter Standley : in this numerous new species are described, including four of the hitherto monotj^pic Acrosynanthus. The issue of l^otes from the Itoyal Botanic Garden, Edinhurghy dated November 1918, contains the first instalment of a series of papers on the '* Regional Spread of Moisture in the Wood of Trees," by Mr. W. G. Craib, wherein " Deciduous-leaved Trees during the late Autumn to early Spring " are considered. Tlie pa2)er is accom- panied by five coloured plates and as many diagrams illustrating Moisture Spread in Acer Fseudoplatanus, A LEAFLET (no. 326) on "Injurious Weed Seeds " recently issued by the Department of Agriculture is noteworthy for its excellent illustrations from drawings by Miss Bertha Reid. The plants figured a,re Riimex crispus, H. Acetosella, Cuscuta Trifolii, Dauciis Carota, Geranium dissectum, G. molle, Silene inflata, and Lychnis vesper- tina : in each case the main figures are accompanied by di-awings of seeds and of seedlings in various stages. Botanists as well as gardeners will be glad to hear that the preparation of a new edition of Pritzel's Icones hotanicarum IndeXy second only to the same author's indispensable Thesaurus^ has been begun, and has made considerable progress. It is nearl}^ ten years ago since several influential Fellows of the Royal Horticultural Society urged the preparation, but after some discussion the project fell through. It was revived after the International Horticultural ShoAv held in the grounds of Chelsea Hospital in 1912, when Mr. E. A. Bowles, F.L.S., an active member of the Council of the Royal Horti- cultural Society, succeeded in getting that body to set aside £250 towards the expenses of the new edition, with a sum of £200 annually againiSit the amount, then estimated at £3000. The war prevented any serious attempt at making a start, but two couimittees were set up, one chiefly of cultivators and the other mostly of botanists, to thresh out the problems connected with the venture. Ultimately last year (1918) the plans Avere drawn up, and Dr. Otto Stapf, Keeper of the Herbarium and Library at Kew, agreed to act as Honorary Director, and, with the consent of Sir David Prain, to make use of the material available at that establishment, with its extensive library and trained amanuenses. The bulk of the new edition is estimated at twice that of the original, on practically the same lines. The Garden, which often contains matter of botanical interest, reprints in its issue of March 15 an article from The Journal of Heredity in which the supposed hybrid origin of the Loganberry is called in question. This popular fruit " came to light about 1881 in the grounds of Judge J. H. Logan, of Santa Cruz, California : it was described by him as a natural hybrid, which appeared spontaneously, and he believed that the parents Avere the Auginbaugh (a variety of Buhus vitifolius, a wild Blackberry of California) and a red Rasp- berry, probably the variety Red Antwerp, since the two were growing together in his yard." The hybrid origin, first called in question by Mr. W. 0. Backhouse, economic botanist to the Argentine Govern- ment, is now doubted by others as well as by horticulturists, whose views are set forth at length in The Garden. 105 MYCETOZOA RECORDED AS BRITISH SINCE 1909. By G. Lister, F.L.S. Teis" years have passed since the third and latest edition of the Guide to the British Species of Mycetozoa, j^ublished by the Trustees of the British Museum, appeared. In the preparation ot" a new edition, many changes had to be introduced in order to adai)t the nomenclature to modern requirements, making it agree with that used in the second edition of iYiQ Ilonograph of Mycetozoa, published in 1911, and also to incorporate much additional information that has been obtained. Owing to the cooperation of many observers, five genei-a have been added to the British list and thirty -five species, bringing the number up to 181. For convenience of reference it may be useful to give a few notes on the additional species and varieties, on where aud by whom they were found, and on some points of nomenclature. Badhamia NITER'S Berk. var. reticulata G. Lister, in Trans. Brit. Mycol. Soc. V. 71, pi. 1. figs. 2, 2 a, h, 1914. This variety differs from the t^^ical form in the plasmodiocarp habit of the sporangia and the more loosely clustered paler spores, which have a cap of minute, not coarse warts. The one British gathering was made by my father and myself in November 1888 on an old log at Uj)lyme, Devon. It has been recorded from Poland, Ceylon, and Japan. B. AFFiNis Rost. This inconspicuous species has been found repeatedly on the mossy bark of living trees ever since Nov. 1899, in East and West Aberdeenshire, by the Rev. W. Cran. For years it was put aside as a doubtful form, closely alhed to B. orliculata Rex, from which it differs chiefly in shape and of which it may be only a variety. It has been obtained from Pennsylvania and Japan. Phtsaeum globulifeeum (Bull.) Pers. The one British record consists of a gathering made by the Rev. W. Cran, at Ballogie, Aberdeenshire, October 1913. The sporangia and lime-knots are not pure white, but have a slight brownish shade, suggesting a close rela- tionship with P. murimim Lister, a species which differs in no other respect but its brown colour, and which might be regarded as simply a variety of P. glohuliferiim ; for convenience of reference, however, it would seem better to keep the brown P. murinum as a distinct species, as well as the yellow, orange-jed, purple-red, lilac, and blue forms of ihQ^'' glohuUfertim'''' group, each of which has its separate specific name. P. PULCHEEEIPES Pcck. A fine typical gathering was made by Miss M. Rea in September 1916 in the grounds of Sir John Ross at Rosstrevor, County Down, on a stump in a larch wood (see Irish Naturalist, xxvi. 58, 64) ; this is apparently the only recoi'd for the species beyond the United States. P. Li'TEO-ALEUM Listcr. This handsome species has been found repeatedly since 1910 in an alder copse at Uplyme, S.E. Devon, in early spring. It was also obtained in some abundance last January by Mr. N. G. Hadden at Porloek, Somerset, on dead leaves in a wood JorE^AL OF BoTAj,'!'.— Vol. 57. [May, 1919.] k 106 THE JOUHNAL OP BOTANY of larch and birch. It has been recorded from the south of France, Holstein, and Colorado. P. NUCLEATUM Eex. Found for the first time in Britain by Dr. A. Adams near Looe, Cornwall, July 1911, on dead wood. Mr. N. Gr. Hadden has also obtained it near Lynton, N. Devon, in August 1915 (see Journ. Bot. 1916, p. 200). P. carneuvi Gr. Lister & Sturgis. Found in abundance hj Mr. H. W. Howard in Bramble thickets, near Thorpe, Norwich, in late summer and early autumn 1916, 1917, and 1918 (see Journ. R. Microscop. Soc. 1917, p. 265, pi. xviii.). Except a gathering made near Lisbon by Dr. C. Torrend in December 1907, the only other record for P. carneum is Colorado. P. BRUNNEOLUM (PliiU.) Massco. A single growth was found by Miss M. Rea near Lisburn, County Down, Jul}^ 1917. The specimen consists of gloss}'' brown hemispherical or elongated sporangia on a dead herbaceous stem ; the spores have not matured well, but enough have developed to leave no doubt as to the identit}^ of the species. P. hrunneolum has been obtained from California, Chili, New South Wales, and Portugal. P. ATJEiscALPiUM Cooks. First found in Britain by the Rev. W. Cran in August 1912 on a mossy trunk near Skene, Aberdeen, in which district he has repeatedly obtained it since, and also at Lesmoir, W. Aberdeenshire. Members of the Mycological Society found it in the Altyre Woods, Elginshire, in September 1912. P. CBATERiFORME Pctch. Mr. Cran has obtained this repeatedly on the bark of living trees since 1904, near Skene, Aberdeen. It has also been recorded from Ceylon, Japan, Antigua, and S. Nigeria. P. coxNATUM (Peck) Lister. A single gathering of what appears to be this species was made in November 1898 by Mr. Edgar Saun- ders ; otherwise P. connatum has hardly been recorded beyond N. America. P. VERXUM Somm. var. ibidescens, nov. var. This small iri- descent form is very constant, and appears regularly on dead leaves, especiall}'- holly-leaves, in Epping Forest, Essex, in autumn and winter. It is distinguished by the sporangia being scattered and having scanty or no deposits of lime in their walls, by the lime- knots enclosing unusually large lime-granules, and by the dark brownish-purple spores having a pale patch of dehiscence. It has been found in Bedfordshire, H^ertfordshire, Norfolk, Nottinghamshire, and North Devon, and also in Holstein. FuLiGO SEPTICA Gmcl. var. rufa (Pers.) G. Lister. This dull red variety is not uncommon and has long been recognized. Mr. H. J. Howard finds from his experience that it always arises from cream- coloured Plasmodium. For convenience, it would seem well to mark it with a varietal name. F. SEPTICA var. CANDIDA (Pcrs.) G. Lister. The white variety is more abundant than the red, and arises from a white or cream- coloured Plasmodium. DiDERMA AEBORETM G. Lister & Fetch in Journ. Bot. 1913, p. 2, pl. 524. fig. 2. The first British gathering of this arboreal species was made by Mr. Cran in Oct. 1910 near Skene, Aberdeen, and on MYCETOZOA EECORBED AS BRITISH SINCE 1909 107 most succeeding years he has found it there in late summer and autumn. Dr. A. 'Adams also obtained an extensive growth, on a mossy beech-trunk, near Looe, Cornwall, in July 1917. It has been recorded from Ceylon and Japan, and recently Mr. A. R. Sanderson has found it at Petaling, Federated Malay States, on the trunks of Hevea hrasiliensis. D. DEPLANATUM Fries. In the British Museum Catalogue this is described as a subspecies of D. niveum Host. ; as, however, it is a constant form, always having a scattered plasmodiocarp habit, it seems better to retain for it the name given by Fries, and to regard D. niveum, with its crowded hemispherical sporangia, as a separate species. D, niveum is very abundant on the Alps in spring, and has not been found in Britain. D. EADIATUM (L.) Lister var. umhilicatum (Fries). The type of -D. radiatum in the Linnean Herbarium has brown sporangia dehiscing with petal-like lobes : transitional forms occur connecting it with what was described by Fries as D. umhilicatum, a form with pale drab sporangia which burst irregularly. As M. Meylan has pointed out, this pale variety deserves some distinction ; whether it is regarded as a separate species or as a variety of D. radiatum is a matter of little consequence (" Myxomycetes du Jura " in Ann. du Con- servatoire de Geneve, 1918, p. 312). D. RADIATUM var. montanum Mejdan {op. cit. p. 312). In this variety the outer layer of the sporangium-wall is white and separates easily from the membranous inner wall ; the spores are usually rather smaller than in the tvpical form, and measure 7 to 9 ju instead of 9 to 11 ^. D. ASTEROIDES Listcr was first found in Britain in October 1910 by Mr. W. H. Burrell, who gathered it on the stems of Eciuisetum palustre on marshy ground on Flordon Common, Norfolk, It has since been obtained by Mr. W. B. Allen in Shropshire and by Mr. N. Gr. Hadden in West Somerset. It was also found in abun- dance in a deep bed of holly-leaves in woods at Cawdor, Nairnshire, in September 1912, by members of the British Mycological Society. Outside Britain it has been recorded from Portugal, the South of France, Switzerland, N. Germany, and Colorado. Leptoderma iridescens G. Lister in Journ. Bot. 1913, p. 1, pi. 524. fig. 1. This was first found in March 1892 on pine bark and needles at Leighton Buzzard, Bedfordshire, and was named by my father provisionally Lamproderma physaroides Rost. var. sessile Lister. In November 1911, Miss K. Higgins discovered a fine growth of the same form in woods at Woburn Sands, Beds, in which all the characteristic features were displayed — namely the sessile habit, the granular deposits in the sporangium-wall, and the dark grey spinulose spores. It was then published as the tj^pe of a new genus. Subsequently it has been obtained at Porlock, Somerset, in Inverness-shire, in N. Germany, and several jmrts of Switzerland. Colloderma oculatum (Lippert) G. Lister. The first British gathering was made by Mr. Cran in Aberdeenshire, October 1910. It now appears to be fairly abundant in many parts. In Ej^ping Forest, Essex, it has appeared every autumn since 1911 ; it has also been, K 2 108 THE JOURNAL OF BOTANY recorded from Yorkshire, Shropshire, Worcestershire, Somerset, Devon, and from the south of Scotland ; also from the -Tyrol, Switzerland, Portngiil, New South Wales, Japan, and New Hampshire. Stemoxttis hyperopta Meylan in Bull. Soc. Vaud. Sc. Nat. lii. p. 97. 1918, syn. Comatricha typlioides Rost. var. heterospora Ilex. It has been found from many years' experience that this form is remark- ably constant. It differs from C. typlioides in the rosy-lilac colour of the sporangia, in their more clustered habit, in the smoother and more complete surface-net of the capillitium, and in the spores showing small patches of reticulation on their surface when highly magnified. It may seem a great change not only to make this form a distinct species, but to place it in another genus, but in reality it is not so, for Comatricha is only distinguished from Stemouitis by the more scattered habit of the sporangia and by the absence of a smootli surface-net to the capillitium, and it is for convenience, rather than as a natuml arrangement, that the genus is retained at all. Comatricha cornea G. Lister & Cran in Journ. Bot. 1917, p. 121, pi. »548. fig. 1. First discovered by the Rev. W. Cran near Skene in June 1913, and again in 1914 and 1916. M. Me3dan writes that he has found this minute S}>ecies in the Jura Mountains. C. FiMBRiATA G. Lister & Cran in Journ. Bot. 1917, p. 122, pi. 548. fig. 2. First found by Mr. Raymond Finlayson in Wanstead Park, Essex, in November 1913 ; since obtained by Mr. Cran near Skene, on Hind Head, Surrey, by myself, and twice by Mr. H. J. Howard in Norfolk. C. MiCROSPORA G. Lister: syn. C. typhoides var. microspora Lister. Repeated gatherings f)i'C)ve that this is a constant form worthy of specific rank ; the closely flexuose character of the surface- net of the capillitium and the very small spores distinguish it from C. typhoides. It has been found in Devon, Surrey, Essex, and Nor- folk, and be3^ond Britain in Holstein, near Berlin, and in Ohio. C. TENERRIMA (Curtis) G. Lister : syn. C. pidchella Rost. var. tenerrima Lister. It is with some hesitation that the specific rank given to this form by Curtis is once more adopted. When typically developed C. tenerrima differs strikingly from C. pulchella in having pale red narrowly ovoid sporangia on long slender stalks, instead of reddish -brown broadly ovoid sporangia on short stalks, but it must be acknowledged that forms intermediate in character sometimes occur. Lamproderma violaceum (Fr.) Rost. var. dehile G. Lister & Howard in Journ. Bot. 1919, p. 25, pi. 552. fig. 1. Found by Mr. H. J. Howard in April and May 1918. L. atrosporum Meylan var. anylicum G. Lister & Howard in Journ. Bot. 1919, p. 27, pi. 552. fig. 2. Found with the preceding on the same leaf -heaps. L. INSESSUM G. Lister in Trans. Brit. Mj^col. Soc. 1912-13, p. 41, pi. 1. fig. 2. Found only once on lichen at Forres, Elginshire, Sept. 1912. Clastoderma Deraryanum Blytt. This minute species was discovered for the first time in Britain by Mr. N. G. Hadden at Porlock, Somerset, December 1918, on old gorse stems ; when found MTCETOZOA RECORDEiy AS BEITISH SINCE 1909 109 the sporangia were immature and watery white, but soon changed to the inconspicuous brown mature stage. Amauroch^te cribrosa (Fries) Sturgis in Mycologia, ix. p. 328 (1917). This species has long been included under A. fuligiiiosa (Sow,) Macbr,, from which it differs in the sethalia being smaller, rounder, and more compact, and, when perfectly formed, being clothed with a fragile membranous cortex, which either breaks into fragments adhering to the tips of the capillitium or entirely dis- appears ; the capillitium closely resembles that of Stemonites con- Jiuen% Cooke & Ellis, to which A. crihrosa appears to be closely allied. There seems to be every probability that this is the species described by Fries as Lachnoholus crihrosus (Syst. Orb. Veg. p. 148) as long ago as 1825, the type of which is lost. In Britain it was found near Smethwick, Staffordshire, by Mr. A, Camm, August 1895, and by Mr. T. Fetch in Hull dockyard in Sept. 1903, Elsewhere it has been recorded from Sweden and Norway, and in North America from the States of Massachusetts, Pennsylvania, and Washington. Cribraria yulgaris Schrad. In the British Museum Catalogue this is named G. aurantiaca Schrad., and two varieties are dis- tinguished : — -form a, a short-stalked form with broad nodes to the sporangial net, a,nd form /3, a long-stalked form with naiTow nodes. The species is very variable, but a more natural arrangement is that proposed by Meylan (in Ann. du Conservatoire de Greneve, 1913, p. 317) ; he regards C. vulgaris as the typical form, having slate- grey Plasmodium, usually short-stalked sporangia with ochraceous spores, and either broad or narrow *' nodes " ; and var. aurantiaca Pers., having green plasmodium, usually longer stalked sporangia with golden-yellow spores, and polygonal nodes approaching in character those of C. tenella Schrad. or of G. intricata Schrad. LiCEA CASTANEA G. Lister. Discovered by Mr. Cran at Lesmoir, W. Aberdeenshire, November 1910, and found again repeatedly by him both there and near Skene. It has also been obtained by M. Meylan in the Jura Mountains. L. MiNTMA Fries. Recorded first in Britain by the late George Massee, from Bulmer, Yorks ; found since in Bedfordshire, East and West Aberdeenshire, and Inverness-shire ; recently Miss M, Rea has obtained it in County Down. HvMEXOBOLUS PARASITICUS Zukal. Fii^t found in Britain by Mr. Cran at Rhynie, West Aberdeenshire, June 1894, and since obtained repeatedly by him both there and near Skene ; also found in the Cawdor Woods, Nairnshire. Orcadella operculata Wingate, Recorded first from Britain by Mr. W. H. Burrell from Stratton Strawless, Norfolk, January 1909, on liverworts on a living beech-tree. Mr. Cran finds this inconspicuous little species in abundance, also on living trees, near Skene. It has been recorded elsewhere from Holstein, Japan, and in North America from the States of Maine and Pennsylvania. Enteridiu^c liceoides G. Lister. This has hitherto been re- tained as a variety of JE. olivaceuniy but, though nearly allied, it always exhibits the flat pkismodiocarp habit, and the pseudo-capilli- 110 THE JOURNAL OF BOTANY tium is represented by columnar props instead of a network of broad strands. It has been obtained in Devon, Somerset, Wiltshire, Hamp- shire, Surrey, Bedfordshire, Norfolk, and Argyllshire ; also from France, Brandenburg, and New Hampshire. Triciiia floriforme (Schweinitz) Gr. Lister, syn. T. Bofryfis Pers. var. lateritia Lister. The constancy of this handsome form fully entitles it to specific rank. It dilfers from all varieties of T. Botrytis in having dark red translucent stalks entirely free from refuse-matter, as well as in the orange-coloured spores. It seems unfortunate that the familiar name lateritia^ published by Leveille in 18-1(5, cannot be retained ; but Dr. Sturgis found, when examining the Schweinitzian herbarium, that the specimen described as (7r«- terium iioriforme^(i\\\\idm\t7. in 1S82 is plainly the species in question, and, by the rule of priority, tlie older name must be adoj^ted. Although widely distributed, T. jioriforme is not common in Britain; it has been recorded from Somerset, Wilts, Middlesex, Leicestershire, and Shropshire. T. Botrytis Pers. var. cerifera G. Lister in Journ. Bot. 1915, p. 211. Recorded in Britain from Derbyshire, Bedfordshire, Essex, Somerset, and Dorset ; also from New South Wales. Hemitrichia leiotricha Lister. Recorded in Britain from Dorset, Devon, Surrey, Essex, Hertfordshire, Bedfordshire, Shro])- shire, Northumberland, and Aberdeenshire; also from Norway, Sweden, North Germany, Switzerland, and Ceylon. H. ABIETINA (Wigand) Lister. Found for the first time in Britain in the Woodhouse Pinetum, Uplyme, Devon, in February 1905 ; also obtained near Swarraton, Hants, and Hind Head, Surrey. H. MINOR G. Lister. The typical form was first found in Britain by the Rev. W. Cran, near Skene, February 1912 ; and he has met with it again repeatedly there and also at Lesmoir, West Aberdeen- shire. Mr. N. G. Hadden obtained it on the mossy bark of living trees at West Porlock, Somerset, November 1916. Here he also found the handsome little dark-spotted var. pardina Minakata, growing on hedge-clippings, in January 1919. In this gathering the spirals on the capillitium are unusually well developed and are dextral in arrange- ment, whereas in all specimens of typical H. minor hitherto obtained the direction of the s^Dirals is sinistral, as is usual in the Trichiacecd. In the type of var. pardina from Japan, the capillitium has faint and variable spirals, some being dextral, others sinistral. Guided by this character of the spirals, I examined a number of our old mountings, with the result that I came across the record of two gatherings of what I doubt not should be called H. minor var. pardina, made at Lyme Regis in the years 1891, 1899. They came from the same leaf-heap, and each consisted of a single sporangium. In appearance they are shortly stalked and glossy yellow spotted with prominent dark brown warts ; the capillitium shows dextral spirals ; one had been called " H. Karstenii F," the other ** T. erecta Rex," and afforded the only evidence for the occurrence of that species in Britain. T. erecta is a much more sturdy species and has rich orange- yellow capillitium with spinulose sinistral spirals ; it is widely dis- ilYCETOZOA EECORDED AS BRITISH SINCE 1909 IH tributed, having been recorded from the Eastern United States, from Victoria and New South Wales, and from New Zealand ; it is to be hoped that eventually it may be reinstated as a British species. H. LEiocAEPA Cooke. The single British record is a specimen found on Sphagnum in an orchid house in the Eoyal Botanic Gardens, Edinburgh, in 1878. In this gathering, as well as in the type from Harps well, Maine, and in a specimen found by Mr. Hugo Bilgram near Philadelphia in 1914, the spirals of the capillitium are all dextral; on the other hand, the type of H. Varneyi Rex from Kansas, which is included under K. leiocarpa in the British Museum Catalogue, had sinistral spirals. How far the direction of the spirals is a reliable diagnostic character is uncertain in the present state of our knowledge. H. leiocarpa is closely alhed to R. clavata Rost. CoRis^iiviA Serpfla (Wigand) Rost. Found in abundance on heaps of spent tan, at Grampound, near St. Austell, Cornwall, in April and May 1906, by Mr. J. M. Coon. This is the only British record. Arctbia ii«"8iGias Kalchbr. & Cooke. The only British gathering known was made by Miss K. Higgins in woods near Luton, Beds, in August 1916. Perich^j^a corticalis (Batch) Rost. var. liceoides Lister. Found on hedge-clippings, January 1919, by Mr. N. G. Hadden, near Porlock, Somerset. The minute shining yellow sporangia are both clustered and scattered about the dead herbage, and closely resemble those of an Oligonema, but the translucent walls are" in some sporangia mottled with deposits of dark refuse-matter ; the capillitium consists of a close network of nearly smooth irregular threads ; the spores are minutely warted and measure 12 /it in diameter. This specimen is similar in all respects to one kindly sent by Dr. Jahn from Denmark ; it had developed on the dung of fallow-deer. Other gatherings of this variety have been obtained on the dung of hares and rabbits in Germany, on old willow-bark in Carinthia, and on old cow-dung in Florida. P. YERMicuLARis Rost. var. pedata Lister (see Mycetozoa, ed. ^, p. 253). It has been found that the specimens with stalked sporangia and smooth capillitium, published under this name from Lyme Regis and from Philadelphia, have far less affinity with P. vermicularis than with P. chrysosperma (Currey) Lister. An extensive series of gatherings of the latter species from Japan shows that the usual characteristic spines on the capillitium are sometimes absent in weak developments; the very faintly papillose sporangium -wall and the dark stalks are not unusual features in P. chrysosperma. The variety pedata of P. vermicularis should therefore be suppressed. In conclusion, I wish to express my sincere thanks to the friendly correspondents who have given me permission to make free use of their observations. 112 THE JOURNAL OF BOTANY ALABASTRA DIVERSA.— Part XXX * Br Spencer Le M. Moore, B.Sc, F.L.S. (Concluded from p. 91.) 2. TuTMELEACEiE AFRICAXiE XOY^ YEL NOTARI DIGN^, In writing the following descriptions, the view held by recent authors that the organs found, when they do occur, usually at the throat of the calyx of ThymeleacecB are petals, has not been followed. That view was not without support among older writers ; thus Lindley calls the organs in question " scale-like petals," and Eichler alludes to them as ** Kronblatter (Schlundschiippchen)," which ma}^ be re- garded as a sort of " sitting upon the fence " ; but Meisner, whose work upon the group is of great importance, always speaks of " squamulse," while Endlicher boldly names them sterile stamens. Baillon, while adopting the " scale " view, says of Dicranolepis that the scales resemble a corolla. In spite of this extreme case and of a certain analogy with Dichapetalum, it seems not improbable that these organs are really not petals at all, but either transformed parts of the andrcpcium or new structures arising independentlj^ and functioning in the pollination of the respective species bearing them. In any event, it would seem better at the present stage to use a non-committal term rather than the definite one now coming into fashion. Struthiola epacridioides C. H.

ILFRACOMBE MOSSES AND HEPATICS. By Cecil P. Hukst. (Concluded from p. 97.) Sarhtila cordata Dixon. First noticed on a wall-top at Sauntoii by Mr. Holmes in April 1903, and was only known until quite recently from Central Europe (Austria, Germany and Switzerland) ; in 1902 it was gathered in Pyrenees by Messrs. Dixon and Nicholson the latter of whom writes : — " I found B. cordata on the Saunton cliffs in North Devon in October, 1916. It grew in a scattered way practically all along the cliffs, but I think that it was most plentiful at the end nearest to Baggy Point." — B. topliacea Mitt. Fruiting freely on the cliffs to the east of Ilfracombe ; I think I have also 120 THE JOUENAL OF BOTANY seen the capsules on Braunton Burrows. Mr. Knight writes :^ '* I fancy that some mosses which seem to be confined to a calcareous element inland are not so particular when growing near the sea. — J5. topliacea seems to be always common near the sea whatever is the nature of the soil." — B. rigidula Mitt. c.fr. on the coast at Lee and near the Watermouth Caves on a wall, apparently not uncommon on rock in the Ilfracombe neighbourhood. — B. Hornschucliiana Schultz. Small roadside quarry near Iron Letters Cross, Ilfracombe, in small quantity; very fine on a golfing green on the Lee Golf Links ; in extremely small quantity on Braunton Bun-ows. Weisia viridula Hedw, c.fr. in sandy places near Ilfiucombe, I did not see much of this but it is no doubt not uncommon on sandy banks in the district. — W. verticillata. Wet rocky bank near Berrj'-narbor ; rock-crevice on Capstone Parade, Ilfracombe ; cliffs near Haggington Beach, where I found capsules in fair quantity ; the fruit is very rare. T7Hcliostomu7n crispulum Bruch. Rather common on banks, rock-faces, etc. especially on the calcareous eastern side of Ilfracombe, fruiting on stony banks on the south side of the road from Water- mouth Castle to Combemartin ; the fruit is particularly fine and plentiful in a small limestone quarry in a field a little to the south of this road. Capsules are rare in this plant, but Mr. Dixon tells me he finds that, when produced, they generally occur in some quantity. — T. mutahiU Bruch. Bather common and often very fine around Ilfracombe on rocks and banks ; the fruit, Avhich is rare, occurs sparingly on a rocky bank on the south side of the road from Water- mouth Castle to Combemartin. — T. mutahile var. littorale Dixon. Common and very variable all round Ilfracombe, growing plentifully on the rock-faces on Capstone "Parade and also on Lantern Hill ; a very small-leaved form occurs which Mr. Knight says he has seen elsewhere. — T. Jlavovirens Bruch. Fairly plentiful on sand at Braunton Burrows ; a curious form occurred on rock in some quantity in a small cove near Bull Point Lighthouse, about it Mr. Dixon wrote : — " It is an unusual form with leaves acute and nerve longly excurrent ; not, I think, at all common, but I have gathered it in Hants, and one or two other localities." The only record for the fruit of this moss appears to be near Falmouth in 1898 by the Bev. W. H. Painter. — T. nitidum Schp. Rather common in and around Ilfracombe ; I noticed it on the churchyard wall of the parish church and on a wall close to Wildersmouth beach, near Marine Place. *Bleurochcete squarrosa Lindb. On sand at Braunton Burrows in two localities near where Ammophila arundinacea has been planted ; also very sparingly near the lighthouse on Braunton Burrows. Mr. Dixon wrote : — " The leaves of the Bleurochcete you send from Bi-aunton Burrows are unusually entire or subentire at times, but scarcely constantly enough to form a var. or form." Zugodon viridissimus R. Brown. A form occurred rather plentifully and fruited freely at the roots of trees by the small stream near Watermouth Castle. Mr. Dixon wrote : — " The Zygodon must be referred to Z. viridissimus. The leaves are sometimes longly apiculate, but even then it is not the nerve that is excurrent ILFRACOMBE MOSSES AND IIEPATICS 121 or very rarely ; and it is not the stout mucro of Z. Stlrtoniy — Z. Stirtoni Schp. Kather common on rock-faces in and around llfracombe, growing on Lantern Hill (where I found capsules) and on Capstone Parade ; it also fruits on a rocky roadside near Hele, close to llfracombe, the capsules are i*arely produced. I noticed a form with markedly recurved leaves near Score ; of a plant that occurred on a rock-face near Torrs Park Poad Mr. Dixon wrote: — '*I should refer your Zygodoii to Z. Stirtoni-, the better developed leaves have distinctly that apex ; but there are a great many with quite the normal apex of viridissimiis. It is a good illustration of the poor title Z. Stirtoni has to specific I'ank." JJlota crispa Brid. Not uncommon on trees around llfracombe, producing capsules freely. Mr. Knight writes : — " I have always had considerable difficulty in distinguishing between TI. crispa and Z7. Briichii, unless one finds them in good conditions, with capsules just ripe and immediately after the fall of the lid. In Grloucester- shire, where they are scarce, it is difficult to find Tllota in good condition, and you never know when to get ripe fruit in a dry climate like we have here. I have found plants with full-grown but unripe capsules as late as January. In JJ .

Schistostega osmundacea Mohr.* In rabbit-holes near North Moulton ; Mr. Hiern writes : — " >S^. osmundacea grows in the S.W. bank of the road, in the parish of Arlington, about a furlong (say, 200 metres) from the guide-post at White Cawsey, towards Arlington, at altitude about 260 metres. Another station is just in the parish of Morte-hoe on the confines of Georgeham parish, in the old disused Spreacombe iron mine, about 120 metres altitude, about 4 miles from Bmunton and rather more than 2 miles from Morte-hoe railway station." The moss was accidentally discovered in this locality by Mr. E. Vidal in 1906 while geologizing ; it grows plentifully with the hepatics Calypogeia arguta and Diplopliyllum albicans on the sides and floor of a cave in Devonian Sandstone, which the highly refractive protonema illumines with an exquisitely lovely soft golden green light. In the summer the fruit is produced freely in this station. Mr. Hiern mentions that it occurs in five (1 Barnstaple, 5 Honiton, 6 Torquay, 7 Plymouth, 8 Tavistock) out of the eight botanical districts into which Devonshire is divided. Bartramia pomiformis Hedw. Wall-crevices on the east side of the road north and south of MuUacott Cross near llfracombe. Ptilonotis fontana Brid.

Through the kindness of Dr. Rendle I have had the opportunity of examining from time to time a charophji:e which has for some years past been in cultivation in a glass jar in the Botanical Depart- ment of the British Museum. The circumstances in which the plant was obtained are somewhat unusual. Mr. T. V. Hodgson, of the Plymouth Museum, being interested in the Entomosti-aca, and hearing of Professor Sars's experiments in raising those creatures from dried mud, asked his brother, Mr. E. Eoscoe Hodgson, who was residing at Port Ehzabeth, Cape Colony, to send him some mud from any local dried-up pond. The latter accordingly in about the year 1896, forwarded some nine or ten pounds of nearly dry mud from a dried-up " vlei " near the town. Mr. T. V. Hodgson sent some of this mud to Professor Sars, and both of these gentlemen raised from it a number of Entomostraca ; the result of Prof. Sars's investigation was published in 1898. The mud also contained vegetable matter, and from some of this, which had been sent to Dr. Caiman and placed in water, the charophyte grew u]) together with a species of Riella. The charo- phyte produces oogonia and antheridia in abundance, but I have seen no ripe oospores. I feel, however, veiy little doubt in referring it to a weak form of Lyohuothamnus macropogon Braun, a characteristic Australasian species, which had not I think hitherto been known from Africa. In all the fertile whorls of the South African plant which I have examined, oogonia are produced in the axils of the branchlets, as in L. macropogon^ but not also at any of the free branchlet-nodes ; and this added to the absence of ripe fruit militates against an entirely satisfactory determination. It is to be hoped that further material from Cape Colony will be forthcoming to settle the matter. The extremely long stipulodes, of which there is often a second W'horl above the branchlets and which gave rise to the specific name macropogon, are but feebly represented in the South African plant, and, indeed, at some nodes are quite wanting. It is possible that this, as well as the defective development of the fruit, may be due to impaired vitalit}^ owing to the plant growing under unnatm-al con- ditions. The pronounced development of the stipulodes is, moreover, by no means constant in L. macropogon. A large number of speci- mens of that species were collected at Hawkes Bay, New Zealand, by the late Augustus Hamilton, for many years Director of the Dominion Museum at Wellington, who, through the kind offices of Mr. Walter Barratt was good enough to present them to my late brother and myself. An examination of these disclosed a great variation in the development of the stipulodes, which range from tiny conical pro- cesses about 150 /x in length to the characteristic long slender ones attaining to about 1600 /u, but never reaching to the extraordinary length of those of the typical Australian plant, so well shown in Kiitzing's beautiful drawing, Tab. Phvc. vii. t. 46. In the Hawkes Bay plant I have not observed any whorls destitute of stipulodes, but in some of them the circle is imperfect. The entire absence of these organs from some whorls of the cultivated South African plant has 12G THE .TOritXAL OF BOTAXY not therefore the importance which it would have appeared to possess if we had only the typical Australian plant with which to compare it. I take this opportunity to refer to the generic position of this plant, and of the other species which have been placed under Lyclino- thamnus. That genus was first established as such by Leonhardi, in Lotos, xiii. p. 72 (1863), having previously been differentiated in 1845 by Ruprecht (Symb. ad hist, et geogr. pi. Eoss. pp. 79, 80, and Distr. Crypt. Vase. Imp. Ross. p. 11) as a subgenus, to include the species in Braun's section *' Charte pleurogynae," viz. O. harhata, C. impulosa (under two of its synonyms C. Wallrothii and C. Poii- zohii), and C. macropogon. In Braun's papers from 1849 onwards the name Lychnofhammis was adopted as a subgenus. In the con- spectus to Die Characeen Afrilio's, hoAvever, Braun, though still keeping it as a subgenus, preceded the specific names with an " X." instead of a *' C." In Braun and Nordstedt's Fragmente einer Monoqrapliie der Characeen (1882) the genus was recognised as distinct, but important changes were made in its constitution. Char a jiapalosa (under another of its s^-nonyras, C. alopecuroides) was removed into a new genus, Lamiirothamniis^ and Chara stelligera ( = C. ohfusa, De^viiwx) was added to Lychnothamnus, so that the latter genus consisted of three curiously unlike j^lants, L. stelligery L. macropogon, and X. harhatns. The distinctive character of Lychnothamnus is that the antheridia are produced by the side of the oogonia, and as shown in the dia- grammatic figures of X. harhatns, nos. 191-4, t. vi. of the Fragmente, they proceed from separate peripheral cells of the branchlet node, whereas in Lamprotliamnium { = Lamprothamnns Braun, non Hiern) and Chara both sexual organs arise from the same peripheral cell, in the former genus the antheridium being situated above (or occasionally beside the oogonium, and in the latter below it. Now it happens that of the three species placed under Lychnothamnus in the Frag- mente, it is only in the one, L. harhatus, that the relative position of the sexual organs can be satisfactorily ascertained, since L. stelliger is di(ecious, and in L. macropogon, while the antheridia are normally produced at the free nodes of the branchlets and occasionally some- wliat irregularly at their base, the oogonia are usually produced only at the basal-nodes in the axils of the branchlets, and when occasionally also at a free branchlet-node scarcely ever at one where there is an antheridimn. I will refer later to instances in which to ni}^ knowledge they have been found together. *In 1889 Professor Hy (in Bull. Soc. Bot. France, xxxvi. p. 398 (1889) constituted a separate genus, Nitell apsis f or X. stelliger, and this separation was concurred in by Dr. Migula, who, however, gave it a fresh generic name, Tolypellopsis. Though the distinctive characters relied upon by these authors are purely vegetative ones, the genus appears to me to be a natural one. It is, however, perha]is a case where " knowledge falls short of conviction " ! The simple structure of the plant as compared with other Charece, seems to mark it out as belonging to an archiac type, and the fruits more than those of any other living species approximate in shaj^e and size to the big NOTES ON LTCHNOTHAMXUS 127 globular fruits so characteristic of the Oligocene beds, the original " gjrogonites " of the earlj^ geologists. The generic name Mtelhjjsis Hj, antedating that of Tolypellopsis must be retained, and as the oldest specific name for the single species is Cliara ohtusa Desvaux (1810), to complj with the International Rules, the name must stand as Nitellopsis obtusa, the synonymy being as follows : — NiTELLOPSIS OBTUSA, COmb.

This species has, I believe, so far been recorded from European localities only. There is, however, a specimen in the herbarium of the Calcutta Botanic Gardens, collected in 1892 by Abdul Huk, at Fort Stedman, Upper Burma, which, in my late brother's opinion and my own, can only belong to N. ohtusa, or some very nearly allied species. The specimen is unfortmiately an extremely poor one and is ' sterile, so that conclusive determination was not possible. It would be satisfactory if perfect specimens of the plant could be collected, as if it should prove to be N. ohtusa it would represent an important extension of its known distribution and, if a new allied species, of immense interest. In examining L. macropogon the next species of Lychnothamnvs in the Fragmente, one is struck by the great similarity in its vegeta- tive parts to our European Lamprotharmiium papulosum {^Lampro- thamnus alopecuroides Braun). In the Fragmente (p. 100) is the fol- lowing remark: — '' LyclinotJiamniis macropogon macht Schweirigkeit, ist nach Habitus ein Lamprotliamnus, nach der Stellung der Sporan- gien eher ein Lychnothavimis.'''' Braun does not however mention having found an antheridium and an oogonium at the same free node 128 THE JOURNAL OF BOTANT of a branchlet, and his remarks rather infer the contrary. In a specimen collected in 1898 b}^ Mr. F. M. Reader at Polkemmet, in the Wimmera River Valley, Victoria, my late brother found an instance of an antheridium and an oogonium at the same free node, and although produced side-by-side proceeding from the same peri- pheral cell, corresponding therefore with LamprotJiamnium rather than with Lychnothammts. The coronula of L. macroj^ogon more- over closely resembles that of L. j)api(losum, and is quite unlike the diminutive coronulas of L. barbafus and Nitellopsis obfitsa, which in size approach more nearly to those of the Nitellece. If the evidence ended here I should feel little hesitation in proposing the transfer of L. macro-poqon to LamprotJiamnium. but in a specimen collected by Mr. S. T. i)unn in a freshwater lagoon, at Shebo, Hong Kong in ibO'j (No. 178-i), which in other respects closely resembled L. macro- poqon, and which we came to the conclusion must be referred to that species, we found two instances where an oogonium and an antheri- dium were produced at the same free branchlet-node, both organs in each case proceeding from the same peripheral cell, but the antheri- dium being below the oogonium. This position would, according to the recognized characters, necessitate the plant being placed under Char a. In view of these facts it is difficult to decide where the species is best located. Four alternatives j^resent themselves, to all of which there are objections. To take first that of allowing it to remain in Lychnothamnus, this must, I think, be rejected, considering the pohit of origin of the antheridium when produced in compan}^ with an oogonium at a free node in Reader's and Dunn's specimens. This character, as well as the size of the connula, appears to me conclusively to separate it from L. barbatns, which must be regarded as the type of the genus. The second alternative, that of placing it under Lamprotliamnium on accoimt of its great resemblance to L. papu- losnm, would, if our determination of Dunn's plant is correct, mean setting aside the one distinguishing character of that genus. A third alternative is that proposed by Dr. Migula, who placed L. macropogon in a separate genus and named it Macropogon aus- iralicum {Die Characeen, 1. c. p. 273, 1891). He did not, however, diagnose his genus, and I am at a loss to discover any character or set of characters upon which such a genus could be based. The pro- duction of oogonia in the axils of the branchlets, evidently their normal position in L. macropogon, is not peculiar to that species, several of the Charce, sect, liaplostepliance producing them in the same position, and the presence of a single stipulode opposite the base of each branchlet is also common to more than one Cliara of the same section, while the great length of the stipulodes, apart from its not being a satisfactory generic character, is as already stated, by no means constant. For the present — at any rate until more evidence is forthcoming — the most satisfactory course seems to be to adopt the fourth alternative of reinstating the species in the genus Cliara, placing it next to C. succinct a, with which it has much in common, the main differences NOTES OX LrCHNOTHAMNUS 129 being that in the latter species oogonia are produced on the outer side of the branchlets as well as in their axils, and that the stipulodes are of a diiferent shape. The separation of Nifellopsis and the removal from the genus- of L. macropogon would leave the one well-marked species, Z. har- hatus, in Lychnothainnus. The plants from which Miss McNicol obtained the facts for her admirable paper " The Bulbils and Pro-embrvo of Lamprofhamnvs alopecuroides A, Braun " {Annals of Botany, xxi. p. 61, 1907), were also raised from mud derived from the neighbourhood of Port Elizabeth, but I do not know whether or not from Mr. Hodgson's gathering. The possibility of cultivating charoph3'tes in this way from dried mud opens up opportunities of becoming acquainted Avith the life-history of little-known species, and the success which has. attended these experiments points to the desirability of samples of mud being obtained where possible from districts the aquatic vegeta- tion of which has not been worked up. The preservation of specimens in formalin has been of great assistance and is an immense advance- on the dried specimens which formerly represented one's only material, but living plants would, of course, be far better. In examining one specimen of the South African L. macropogon I came across a rather remarkable abnormality, there being no fewer than three oogonia in which the number of spiral enveloping-cells numbered four instead of five. Abnormalities in charophytes are by no means uncommon, but a deviation in the number of spiral cells is of special interest on account of the extraordinary constancy of the number (five), dating back as it does to the earliest undoubtedly characeous fruits which we possess, those from the Oolite. Braun, in referring to the constancy of this character in his paper '* Uber die RichtungsverhaltnissederSaftstrome in den Zellen der Characeen ^ pt. 2 (1858), mentions that he had himself met with only one' exception, that of a four-celled coronula in Chora galioides, which implies also four spiral cells. The only others I have noticed, among- the many thousand fruits which have passed under my observation,, were a single oogonium of Nitella opaca, and a fossil '* fruit " froii*. the Lower Headon beds, each of which had six spiral cells.

A brilliant if iconoclastic writer, Mr. L^^tton Strachey, in the Preface to his Fminent Victorians, has lately con- demned with characteristic exaggeration the " two fat volumes with which it is our custom to commemorate our dead — with their ill- digested masses of material, their slipshod style, their tone of tedious panegyric, their lamentable lack of selection, of detachment, and design " : Mr. Huxley's volumes, although " fat," present the exact antithesis of Mr. Strachey's censure, and are in every respect admirably done : the only possible improvement in arrangemerut would be the placing at the head of each page the date of the events recorded LIFE ATNT' t.ETTERS OF STK JOSEPH nOOKER 131 below, in accordance with the helpful practice adopted in many biog-raphies. It must however be admitted that Mr. Huxley was exceptionall}^ favourably placed as to material : Hooker himself was " an indefatigable letter writer .... add to this his journals of travel, his various books, his scientific essays— the first written at nineteen, the last at ninet\^-four — the material to draw upon has been super- abundant," especially when added to these are the Life and Letters of Darwin and of the author's father. It would be impossible in the space at our disposal to give anything like an adequate sketch of the contents of the volumes : so far as a general sketch of Hooker's life is concerned, this indeed is scarcely necessary, in view of the full notice by Mr, JBoulger which appeared in this Journal for 1912 (pp. 1-9, 31-43). The chapters Avhich tell of Hooker's relations with his family, especiallj^ that devoted to his "early days," which contains an "autobiographical fragment set down late in his life," are of much interest. His father and his maternal grandfather (Dawson Turner) both began their botanical studies with the mosses, and " at the age of five or six" Joseph showed .a love of these plants: "my mother used to tell an anecdote of me that, while I was still in petticoats, I was found grubbing in a wall in the dirty suburbs of the dirty city of Glasgow, and that when she asked me what I was about, I cried out that I had found Bryum argenteum (which it was not), a very pretty little moss I had seen in my father's collection, and to which I had taken a great fancy." The paternal Hooker was not slow to encourage the incipient taste ; at the age of seven Joseph was attending his lectures on botany and he had from an early period expressed a hope that his son would succeed him in the Glasgow professorship. As a result of this poor Joseph's nose was alwa3^s kept very close to the botanical grindstone ; even when he was twenty-three his father's letters " urge to stick to botanical work exclusively— to avoid wasting his time in unnecessary entertainments ; counsel indeed scarcely needed for one who cared so little for the ordinary attractions of Societ}-." Nor did the father hesitate to express his dissatisfaction with the plants sent — this at one time made the son fear that he " was physically incapaci- tated for the high trust reposed in " him. " If ever, on my return," ho wrote from St. Helena in 1840, " I am enabled to follow up botany on shore, I shall live the life of a hermit, as far as society is concerned; like Brown, perhaps, without his genius." The reply throws a somewhat new light on the generally accepted character of ]h-own : " If you are no more than a hermit than Brown, I shall not complain ; whether you know it or not, he is really fond of society and calculated to shine in it ; and to my certain knowledge, never so ha2:)py as when he is in it." Joseph Hooker was not only a voluminous but an excellent letter- writer, and it is not too much to say that the value of the volumes rests largely on the very extensive use that has been made of his letters, which abound in interest chiefly though by no means exclusively botanical. His descriptive powers were considerable — the Himalayan Journals, first published in 1854 and twice reissued in cheap form, illustrates this, and the letters written home during the 132 THE JOURNAL OF BOTANY Antarctic Expedition are only some among the many which might be selected for spacial nuntion. His communications to Darwin, Haxley, Bentham, Asa Grray, Harvey, Henslow and others, especially those relating to the growth and development of the theory of evolution, are particularly note worth}' ; that to Darwin with reference to his (Hooker's) attack on Wilberforce at the memorable meeting of the British Association at Oxford in 1860 is very lively reading. Throughout his career he was in constant contact with leading botanists at home and abroad, in connection with whom items of interest are incidentally mentioned. In almost all such cases Mr. Huxley has added a footnote containing a brief biography ; this could hardly be better done. The Biographical Index of British Botanists has, quite rightly, been laid under contribution : in some instances — e. g. Edward Madden (i. 468) the notice is little more than an expansion of that in the Index. The value of the information given is perhaps best appreciated when it is withheld, as in the case of one "Grerard," whose views on the validity of species are combated (i. 440) ; the context suggests that Grodron is intended, but Hooker could hardly have spoken of him as ** evidently no botanist." More- over, the work criticized — L' Espece — can hardly have been Godron's book so-called, as Mr. Huxley says, inasmuch as Hooker's letter in which it is referred to is dated 184-5 and Godron's volume was not published until 1859. In some cases — e. g. that of William Ander- son, of whom a full account was given in Journ. Bot. 1916, 345- 51 — the biographies in this Journal might have been consulted with advantage. The early wish of Sir William Hooker that his son should succeed him was fulfilled not at Glasgow but at Kew ; Joseph was appointed assistant to the Director in 1856, after various disappointments which threatened his botanical career, and on his father's death in 1865 became Director. Here he set to work to reorganize the establish- ment, which he at once raised to a higher state of scientific and horticultural efficiency, carrying out, often in the face of much official discouragement, developments which he had long seen to be necessary. Five years later Hooker's work was interrupted by a long and bitter personal conflict with A. S. Ayrton, First Commissioner of Works, under whose administration Kew then came. A chapter is occupied with a recital of the main facts of the controversy, which occupied "the attention of both Houses of Parliament and was embittered by the publication of an official report written by Owen, " who," says Mr. Huxley, ** was notoriously hostile to Kew and to its Director for his evidence before the Science Commissioners, and Owen had emplo3^ed all his great dexterity to belittle Kew and its applications of systematic botany, to urge the transfer of its collections to the British Museum, where they would come under his own government, and to insinuate a bitter personal attack on both the Hookers." This sentence, which is not written with Mr. Huxley's usual care and lucidity, hardly explains Owen's grounds for '' hostility" : the Science Commission alluded to is apparently that of 1871, at which the "transfer" of the Museum collections to Kew had been LIFE AND LETTERS OF SIR JOSEPH HOOKER 183 advocated by Bentham and Hooker ; thus Owen's proposition was rather of the nature of a defence. A similar transference to Kew had been advised by Joseph Hooker in 1858 (see Life, i. 881) in " the interests of botanical science " and a like proposal had been made through the Board of Works, apparently at the instigation of Kew, in 18(38 (see Journ. Bot. 1876, 108). Those (of whom the writer is one) who can recall the period will remember that although sj^mpathy was generally extended to Hooker for the treatment he had received at the hands of an otficial who, as The Times put it, had an *' unfortunate tendency to carry out what he thinks right in as un- pleasant a manner as possible," it was felt by some that Hooker's attitude had not always been marked by discretion. Mr. Huxley says that Ayrton's " apparent aim was to drive Hooker to resign, and then convert Kew into an ordinary park, and send science to the right about." That Ayrton had little understanding of the requirements of science I am able to testify : it once fell to my lot to receive him when he visited the Depai-tment of Botany, when I failed to convince him that a single specimen of each plant was not sufficient for all scientific purposes. The controversy which elicited so much warmth, and appro^Driately originated over a heating apparatus, came to an end in July 1872 ; the Treasury Minute on the basis of which it was settled will be found in this Journal for that year, p. 349. From this time until his resignation of the Directorate in 18S5, Hooker's life was occupied by botanical activities, official, literary, and other, of which some account will be found in Mr. Boulger's sketch ah'eady mentioned, although for anything like a complete summary of them the volumes before us must be consulted. "Full of vigour, and indeed continuing an ordinary man's share of labour for another quarter of a century," Hooker in his retirement from office in no way abandoned the interests to which he had devoted his life. A picture of him in his study at Sunningdale shows him sur- rounded by the Wedgwood plaques in which he delighted — the only form of art to which he seems to have had a special attraction. In 1901 he writes : " Kew still claims about one day of the week, devoted to the Botanical Magazine, and I occupy my days here chiefly in dissecting plants for the good of Kew Herbarium, and drawing the analyses on the sheets for the use of those coming after me. This work, dissecting flowers, fruits and seeds, has been a lifelong passion with me ; I often think of my dear father working on his Ferns with unabated energy up to the very week of his death." He writes a graphic account of the coronation of Edward Vll in 1902, at which he was present in " gorgeous sky-blue satin mantle of a G.C.S.I. with a gold star on it as big as a soup plate, and a heavy gold collar no my shoulders." He took part in the Cambridge celebrations of the Darwin Centenary in 1909, when an interesting photograph (here reproduced) was taken of himself and Lady Hooker, with Mrs. T. H. Huxley, the last holding in her arms Ursula Darwin, Darwin's great-grandchild. Up to the last his letters were full of interest and reminiscence; thus in July 1911, writing of Banks, he says : " I well remember first seeing him, when as a bov I was at 134! THE JOURNAL OF BOTANY Kinnordy [probably in 1836], and looking out of the window saw liini wlieeling a barrow of marl up to the house from the pit [to search for shells].'"' The volumes contain several portraits, including the weak study by Richmond, who "has turned me out a very lackadaisical young gentleman," and the excellent one by Herkomer (1889) at the Linnean Society. The appendixes contain a full bibliography, ex- tending from 1837 to 1911, thus'including the posthumous papers on Impatieiis, and a long " list of Degrees, Appointments, Societies, and Honours," which was hardly worth printing — it contains such entries as " Two Jasper Cups from the liussian Emperor : Gift" and '* Con- gratulations from the Linnean Society (on completion of Genera Flantarum) " : a sketch is also given of the extraordinary career of Jorgen Jorgensen, "the Convict King" (1770-1844), whom Hooker met in Tasmania in 1840. An admirable index is provided, in which the summary of the principal events of Hooker's life is particularly well done. Only one detail affords ground for unfavourable criticism : it is to be regretted that the proofs urere not submitted to a botanist for revision, as there are far too many misprints ; in vol. ii. p. 447, we have in one line, consecutively " Alpina, Lygodon Moiigeoltu " and, five lines later, " Minum " ; "the genus Maddenia Rosacece " (i. 468); "• Gymnostonum'''' (L 38); "• Sahularia'''' (i. 76) are in- stances which might easily be multiplied. But this imperfect appre- ciation of Mr.- Huxley's work must not end upon a note of even slight censure upon a biography which will take permanent rank among the best of the class to which it belongs. James Bkitten. BOOK-NOTES, NEWS, etc. At the meeting of the Linnean Society on 20th March, a paper by Mr. Frederick Lewis, F.L.S., " Notes on a Visit to Kunadiya- parawitta Mountain, with a List of the Plants obtained, and their Altitudinal Distribution," was read by the Botanical Secretary. This curious mountain is nearl}^ due west of the sacred " Adam's Peak," and rises abruptly to an altitude of 5186 feet above the sea, and is surrounded by forest. The sunlmit is small in extent, surrounded by precipices, in the path of the S.W. monsoon, which strikes on this isolated peak and by its force dwarfs the vegetation on it. The rainfall on the eastern base is about 230 inches per annum, on the western side about 330 inches yearly. The llora appears to be largely endemic, animal life is practically absent, and wind transport of seeds of those plants which are on the summit seems unlikely. Forty-nine plants were collected on the mountain top in one day's visit, and were determined at Peradeniya ; of the 49, ten only are found outside Ceylon, the remainder being endemic. The President, Sir David Prain, gave an account of his visits to two islands oif the Indian coast. On one of these. Barren Island in the Andaman group, he found that Terminalia Cata^jya, which usually grows close to tlie BOOK-IiOTES, TS^EWS, ETC. 135 sea, extending to the top of the outer cone, apparently due to the rats feeding on the fruit (the " Country Almonds " of Anglo-Indian speech), which, when disturbed, they carried in their mouths up the slopes. At the same meeting Miss M. Rathbone exhibited a series of specimens preserved by submitting them to the action of formalin vapour, as shown in the following statement : — Some years ago it occurred to me to try to find some method of preserving plants which would not destroy either their form or colour. I began by trying liquid paraffin, and this at first gave very promising results; but after a time the specimens became mouldy, and, if antiseptics such as salicj^lic acid were added, the colour disappeared. It then occurred to me to try formalin vapour, hoping that in this way the tissues of the plants might be hardened, and at the same time that the colour might be preserved. Unfortunately, as these specimens show, the results have fallen far short of my ideal ! The colour fades after a time, and the stalks and jDetals often become limp. However, in spite of these drawbacks, I think the method may have its uses, as, in plants preserved in this way, the microscopic characters of the tissues and the form of the flower and relationship of its parts are less altered than in dried specimens, whilst for travellers specimens preserved in this way are lighter and more convenient to carry than plants preserved in spirit. I found that it was best to dilute the formalin with water, and the strength I used was one part formalin to one or two parts of water, and possibly an even weaker solution might answer. Cotton-wool soaked in this solution is put at the bottom of the bottle, or it may be tied round the stalks of the plants, enough being used to ensure a damp atmosphere. Of course the bottles or boxes in which the plants are kept ought to be air-tight, and I found that candle-grease dropped over the cork answered very well. These plants were bottled in 1917, as last summer I was moving about and was not able to make any further ex]3eriments. I have also brought a bottle of African Mari- gold in salicj'lic acid and liquid paraffin, bottled in 1912. It was quite the best of my paraffin specimens, most of which are deplorable objects, and I do not think there is much to be said for this method, as it has all the drawbacks of alcohol and none of its advantages. As regards formalin, I might add I have found that a 1/10 solution in water is quite good for freshwater Algse. I have some bottled in 1911, in which the chlorophyll body in Spirogyra, which shrivels up so easily with most reagents, still shows quite distinctly. At the meeting of the same Society on AjDril 3, a paper, on "An Albino Mutant of Botrytis cinerea, Pers.," illustrated with preparations and lantern-slides, was read by Mr. William Brierley. He stated that the fungus possesses" characteristic black sclerotia, the colouring matter being deposited in the walls of the outer two or three layers of cells. Among the black sclerotia in a pedigree culture a single colourless sclerotium was formed, and on isolation this gave rise to a strain characterized hj colourless sclerotia. Mor- phologically and physiologically the parent and mutant strains are identical, and the only difierence is the lack of colouring matter in 13G BOOK-XOTES, XEWS, ETC. the latter. A generation of the fungus may be obtained in three days, and the two strains tested over very many generations under the most diverse conditions have proved absolutely constant. As the colourless form arose in a " single-spore " culture, it cannot represent ^ strain selected out from an original population ; and as Botrytis cinerea is asexual, the possibility of the new form being a segregant from a heterozygous parent is eliminated. Furthermore, the occur- rence of colourless sclerotia in this fungus is unknown heretofore either in Nature or when the fungus is grown on culture media. There would, therefore, seem no reason to doubt that the colour- less form described is an instance of true mutation in Botrytis cinerea. At the same meeting, a paper on "Variation in Flowers of Jasminuni malaharicuni Wight," by Dr. H. H. Mann, F.L.S., was explained by Dr. Kendle. He pointed out that in the forests of the Western Ghats of Bombay, during the month of April, the jungle is covered with Howers of this fragrant and attractive climber. Between April 13th and 20th, 1916, the author had examined 2789 flowers for the corolla, and found from 5 lobes in 0"33 per cent, to a maximum of 8 lobes in 40 per cent., declining to a percentage of O'O-l for those with 12 lobes. Similarly, the teeth of the calyx were examined in 3560 flowers at the same time, and showed with 4 teeth, 2"56 per cent., with 5 and 6 lobes the maximum with respective per- centages of 46*26 and 47'81, the last being of 8 teeth with 0*22 per cent. He failed to associate any peculiarity with the position of the flowers on the stem or in the inflorescence. A GOOD example of manufactured " flower lore " is supplied by the following paragraph published by the Manchester Guardian. So far as we are aware, its only foundation in popular legend is the name " Calvary Clover," which is bestowed upon the Spotted Medick in common with other plants with spotted leaves from a tradition that they grew beneath the Cross. The botanical information con- veyed in the paragraph is as remarkable as the symbolical : — " Some curious flower lore is associated with the spotted medick (^Medicago maculata). The seeds of the plant are very well protected, enclosed as they are in a prickly ball, and some perseverance is needed to unroll them from this rough covering. The first shoots should appear on Low Sunday, if the seed has been sown on Good Friday — a day with which the plant is connected, as it is known in some places under the name of Calvary clover. The first two leaves which appear resemble those of a sunflower, and symbolise the Incarnation — The Godhood (s/c) and manhood of Christ. At sunset the two outer leaves come together, and the centre one droops over them, suggesting a prayerful attitude of bowed head and folded hands. The leaflets are charac- terised by a heart-shaped purple spot, rather like a drop of freshly spilt blood, which fades as the leaves grow older. The prickly pod encasing the seed may be twisted into a crown of thorns if care be taken. When the fibre is uncovered the form of a scourge is said to be found beneath it. Eleven, the number of the faithful Apostles, is the number of seeds which a perfect pod should contain." 137 . : THE PEOBLEM OF THE BRITISH MARSH OKCHIDS. Bx Colonel M. J. Godfery, F.L.S. As the season is with us when the marsh orchids are in flower, it may be of interest to point out the problems requiring solution. Orchis prcetermissa is used in this paj)er to indicate the marsh orchid with unspotted leaves, other than O. incarnata, and O. lati- folia the one with ringed spots on the leaves. This is not to be taken as an acknowledgement of 'prcBtermissa as a valid name for the plant in question, or as impljnng dissent from Mr. Rolfe's suggestion that the ring- spotted plant is a hybrid. The names are solely used as convenient terms of reference. O. viaculata is em- ployed in the aggregate sense, and includes O. ericetorum Linton. Orchis prj:terj^iissa Druce (Rep. Bot. Soc. & E. C. 340 (1913) 1914, also J. Bot. 1915, 176). On returning to England in August 1914, I was much interested to hear that a new species had been described under this name. I first found it in Surrey in 1916, and was much struck by its beauty, especially by the delicate lavender- mauve of its flowers, which was quite different from anything I had seen on the Continent, except perhaps O. ^palustris at Pisa. I found later it was not alwaj^s of this beautiful tint. Near Godalming I found it in plenty, but here the flowers were red-purple or pinkish rose. Instead, however, of being the rare and local plant I expected, it was reported to be widely spread and plentiful where it occurred. (Its new name implied that it had hitherto been overlooked, and it was diflicult to understand how so striking and abundant a plant could have eluded the keen eyes of field-botanists.) Finally, I read in Mr. Druce's " Notes on the British Orchids " (Rep. 1917, Bot. Soc. & Exch. Club) that Smith's latifolia (Engl. Flora) and the O. in- carnata of the Engl. Bot. were both " mainly yrceiermissa,^'' and that the latifolia of other British authors was either mainly frcGter- missa or included it. It is not therefore a new species in the Sense that it had not been many times seen and recorded before, but only in the sense that it had not been previously differentiated from latifolia. Mr. Rolfe says (Orch. Rev. xxvi. p. 186) that it is quite clear that the name latifolia primarily belongs to the marsh orchid with broad unspotted leaves — in other words, to the one recently described as O. jiraetermissa. He is no doubt right, in so far as it is true that the O. latifolia of British authors was in the main lyrcdter- inissa, as Mr. Druce himself admits, though it also included the ring-spotted plants, and of course hybrids of prcetermissa, for in those days the occurrence of natural h^^brids was hardly yet fully recognized, and they were naturally looked upon as mere varieties of the species. Whether 0. latifolia, as thus restricted by Mr. Rolfe, is the plant understood on the Continent to be O. latifolia L. is another question. Incidentally it may be remarked that if such is the case, tliere is nothing new about O. i^rcBtermissa except the name, which would then automatically fall to the scrap-heap as invalid. In 1918, in a field near Broadstoiie, Dorset, to my surprise, for JouENAL OF Botany. — Vol. 57. [June, 1919,] sr 138 THE JOURNAL OF BOTANY the field though damp was hardly marshy, I came across O. latifolia with ringed spots on the leaves. Presently I found another speci- men, but the leaves were unspotted, and I said to myself " And here is prcetermissa too." On comparison the plants appeared to be identical, except as to the spots on the leaves. I was puzzled at the time, but on maturer reflection I am strongly inclined to think that the plant with unspotted leaves was not 'prcetermissa at all, but simply a form of the ring-spotted latifolia with unspotted leaves. I have, I believe, seen similar plants in Somerset and Hants, and I think it is a question worth studying whether Mr. Druce has not drawn his net too wide in the matter of prcBtermissa, whether he has not in fact included in it plants identical with the ring-spotted latifolia except as to the absence of spots on the leaves. To clear up this matter it is suggested that the following investi- gations should be made : — 1. Is there in Britain a form of O. latifolia with unspotted leaves distinct from O. prcete^'missa ? 2. Is there a form of prwtermissa only distinguishable from the type by having spotted leaves ? To the best of my belief I have seen the former, but never the latter. Oechis latifolia. Mr. Rolfe, as we have seen, considers O. prcetermissa to be the true O. latijolia L., and even goes so far as to suggest that the figures of O. latifolia L. in Schulze's Orch. Deutschl. (t. 21) and Barla's Icon, des Orchidees represent the hybrid X O. Braunii (latifolia X maculata). These figures, however, are intended to depict the plant understood on the Continent to be O. latifolia L. Schulze knew O. Braunii, and gives a sketch of the lip of this hybrid on the same plate, and also a description, pointing out the characters in which it differs from latifolia. I think we must guard against taking an insular view of our flora ; after all it is only a branch of the larger and much more extensive flora of the Continent. All our orchids are found there with the exception of Spiranthes Bomanzoffiana. It is much safer to interpret our flora in the light of the continental one, than to argue from the smaller to the greater. It should be noted that according to Schulze hotJi the parents of 0. Braunii have spotted leaves. Mr. St. Quintin tells me in a letter that on July 15th, 1914, he and Canon Tmvis visited a marsh of some twenty acres not far from Champery, which was a marvellous garden of marsh plants, thick with O. latifolia, which grew in thousands. Primula far inosa^ Trollius, Bartsia alpina, a few Gymnadenia alhida, an Alliu7n, etc., but O. latifolia predominated. Canon Travis, to whom he has recently spoken on the subject, agrees with him that all the O. lati- folia they saw there were alike, with purple flowers and spotted leaves. They did not see O. maculata that day, though Mr. St. Quintin noted in his journal every species of orchid they found. These alpine latifolia seemed to him wonderfully similar, with little or no variation, and with no suggestion of hybridism. He also says that on June 8th in the Western Pyrenees he found many specimens of 0. latifolia with spotted leaves, and further that, with the excep- THE PROBLEM OP THE BKITISH MARSH ORCHIDS 139 tion of O. incarnata, he has never found any marsh orchid on the Continent with hollow stem and unspotted leaves (except O. paUistris, which is otherwise unmistakable). He is confident that he has never seen, amongst the common spotted forms of O. latifolia, plants with similar flowers and unspotted leaves. These spotted latifolia, then, could not possibly be hybrids — there was no plain-leaved parent and no maculata to be found in the neighbourhood. He also says that *' on the Continent you ma}^ find undoubted latifolia growing in quantity with no other marsh orchis." Personally I have always found latifolia on the Continent with spotted leaves, but I have never seen anything approaching prcetermissa. My ex- perience, however, only extends to a few scattered localities in Southern France, Switzerland, and Italy — I know nothing of Northern France or Central Europe. Ascherson and Graebner (Syn. Mitt. eur. Fl. iii. p. 732) say of the Central European plant that the leaves are usually all marked with black-brown spots, often confluent, oftener faint, more rarely absent. I do not think any serious doubt can be entertained that the plant known on the Continent as O. lati- folia L. usually has spotted leaves. The spots, however, are not always ringed. Mr. St. Quintin says that from recollection he would say that the alpine plants referred to above did not always have ringed spots ; in some, if not in many cases, the spots were solid. Mr. Kaine tells me that at Hyeres latifolia grows with unspotted leaves, and Brebisson in his Flore de Normandie says the leaves are " rarement tachees de brun." These onay he prcetermissay but the fact remains that ring-leaved and spotted-leaved latifolia grow abundantly where p^^cBtermissa does not exist. The Eev. E. S. Marshall tells me {in lit.) that he found at Wexford a plant with short blotched leaves which seemed to agree exactly with one in Herb. Brit. Mus. gathered by Messrs. Britten and Nicholson in June 1882 in Co. Waterford, and named by H. G. Keichenbach as O. latifolia var. brevifolia, and that he obtained other plants in W. Mayo and Caithness, which he referred to this same variety, and noted at the time as having the leaves faintly ring-spotted. He adds " I do not think that these three gatherings come under 0. prcetermissa ; nor are they likely to be hybrids, for which I have kept a good look out." He also mentions that a plant with spotted leaves sent to him from Winchester agrees very well indeed with Schulze's figure of O. latifolia L. (plate 21). I was present at the gathering of this specimen, which was our ordinary ring-spotted plant. I sent a water-colour drawing of O. prcetermissa to Dr. Keller, of Aarau, who has a very wide experience of European Orchids. He did not say, as one might have expected, " This is O. latifolia L.," which he assuredly would have done had he considered it to be that species, but suggested that it might be O. Traunsteineri A. II. Hus- sowii Asch. & Graebn. Syn. iii. 730 (1907) ; their description, howover, does not seem to fit prcetermissa very well. For the above reasons it would seem that while O. j)rcetermissa is no doubt the O. latifolia of most English authors, it is open to question whether it is 0. latifolia L. as understood on the Continent. m2 14u tkr jouexal of botany The Ahgument as to Spots ox the Leayes. Most, if not all, P]aropean orchids with spotted leaves are some- times found without spots. Even O. maculatciy which is perhaps more persistently spotted than any other European orchid, occurs Occasionally with unspotted leaves. Spots on the leaves are. not therefore of specific value, and nothing seems to be known of their cause or object. Our native mascula is sometimes spotted, sometimes not. In 1918, I saw specimens with spotted leaves growing in the midst of a colony of unspotted plants. As both kinds liourished within the same square yard of ground, it was evident that soil and surroundings had nothing to do with the spotting. Mr. H. McKechnie suggested in the Keport of the Winchester College Nat. Hist. Soc. (reprinted in Hep. B. E. C. (1917, p. 187) that ring-spotted latifolia was originally a hybrid between maculata and prcetermissa, and Mr. Druce (I. c. p. 167) regards it as proved that a plant with clear green leaves crossed with one with spots of solid colour will produce ringed spots in the offspring. This theory is so plausible that it is apt to be too readily accepted. Is there any reason wh}'" the circumference of the spot should retain its depth of colour, and the centre revert to the original green of the leaf? Fewer or fainter spots of solid colour would appear to be more truly intermediate. Let us see what happens in the case of other orchids. On June 27th, 1916, I found Oymnadenia conopsea X 0. maculata near Winchester, the leaves were not spotted; another specimen found June 28th, 1917, near Guildford, had spotted leaves, but the spots were solid. I also found Coeloglossum viride X C. maculata near Winchester, the leaves were spotted, the spots not ringed. Plate 15 {I. c), said to be a form of the same hybrid, has unspotted leaves. O. incarnata is unspotted, and so closely related to O. 'prceterinissa that nearly'' all British botanists down to Hooker (and Mr. Druce himself in the 14th ed. of Hayward's Botanist's Focket-hook (1914)), considered it only a variet}^ of O. latifolia. We might therefore expect that in its hybrids it would behave similarly to prcetermissa^ O. incarnata X maculata, however, does not present ringed spots ; according to Asch. & Graebner, and also to Schulze, it is either quite unspotted or weakly spotted with faint spots. A specimen found at Winchester in 1917 had all the leaves unspotted (plate 17, /. c). All this evidence goes to show that when spotted maculata is crossed with an unspotted sj^ecies, whether the latter be O. conopseay Codloglossum viride, or O. incarnata, the offspring is not ring-spotted ; in all these cases the spots either disappear altogether or become fewer and smaller, diminishing in intensity as a whole, not in the centre ox\\y. Lastly, I have found several hybrids between O. prcBt-er- missa itself and O. maculata. One from Godalming had the leaves rather plentifully spotted; one from Winchester (I.e. plate 13) had spotted leaves ; one from the Hog's Back had the lowest leaf unspotted, the upper ones very clearly spotted with small irregular spots. None of these had ring-spotted leaves. On the other hand, a hybrid between Conloglossum viride and O. latifolia (ring-spotted), found at Winchester in June 1917,. had THE PROBLEM OF THE BRITISH MARSH ORCHIDS 141 ringed spots. Dr. Keller, to whom I sent a water-colour drawin"" of this pl.uit, was extremely interested in it, as it had never been found on the Continent, and at once confirmed the identification of O. lati- folia as one of the parents. It is quite evident that by latifolia he did not mean prcBtermissa — first, because two plain-leaved parent^ could not endow their offspring with ringed spots, and, secondl3% because a drawing of prcetermlssa was also sent to him, but he did not suggest that as one of the parents. The hypothesis that a plain-leaved crossed with a spotted-leaved plant will give rise to a ring-spotted hybrid may possibly eventually prove correct, but at present it appears to rest purely on conjecture. I have been so far unable to trace a single instance in which a known hybrid between parents of these classes has presented ringed spots, and of all hybrids between unspotted ^9r<^ferw«/ss« and spotted maculata whioh I havy come across not one was ring-spotted. There are thus two hypotheses to be investigated, i. e.^ (1) That there are only two British marsh orchids, O. incarnafa .and O. prcdtf^rmissa; all other forms are hybrids between one or other of these and O. maculata. Mr. Druee and Mr. liolfe both appear to favour this viSw. (2) That there are three, O. incarnata, O. prcetermissa, and ring- spotted O. latifolia. There are therefore six possible hybrids, viz. (1) incarnata X maculata, (2) prcBteTmissaXmaculatay (3) lati- folia X maculata, (4) incarnataxlatifolia, (5) incarnata.xprcBter- missa, (6) latifolia xprteter miss a. If 0. ericetorum Linton bo regarded as a species, the number i§ increased to nine. It would seem that the bewildering variety of intermediate forms found growing wild is more likely to result from the combinations of a number of different factors, than from the crossing of only two species (when incarnata is absent) or at the most thi-ee. It is suggested that the following points should be investigated, in addition to the two named above : — (3) Are there any localities in which ring-spotted latifolia grows, from yNhioh. ijrcBtermissa or maculata, or both, are absent? (4) Do prcetermissa and maculata grow together in any placp where the ring-spotted plant is absent ? (5) If so, are hybrids present without ringed spots, and are they jiumerous ? (6) Is there any locality in which ring-spotted plants and un- spotted prcetermissa grow together, but where there is no maculata in the neighbourhood ? (7) If so, are the ring-spotted plants identical in every other way with those without spots on the leaves P If any or all of these questions' can be definitely answered, it would probably throw much needed light on a difiicult problem. The most satisfactory thing would be for some of our younsfer botanists to grow unspotted frcdtermissa and maculata, fertilize the flowers of the former with pollinia from the latter (or vice versa), and raise plants from the resultant seeds. It could then be definitely ascertained whether such hybrids ever have ring-spotted leaves. The experiment would take a few years to carry out, but it 142 THE JOURNAL OF BOTANY would solve a problem which has so far baffled all attempts at solu- tion, and also throw a flood of light on the mnge of variation in the offspring of such crosses. It should be borne in mind that the seeds must be sown in pots containing the soil in which the parents originally grew, as the}?" will not germinate unless the microscopic fungus (rhizoctoiiia) which infects the roots of orchids is present (see Prof. F. E. Weiss's paper on Seeds and Seedlings of Orchids in Proc. Manchester Microsc. Soc. 1917). The simplest way is to grow prcetermissa and macidafa in pots, taking up with them the ball of earth in which they grow, and to sow the seeds on the surface of the pots. I should be glad to hear from any readers the results of their investigations, addressed to me c/o Messrs. Cox & Co., 16 Charing Cross, London, S.W. 1. No specimens, however, should be sent till my actual address at the time has been ascertained by a postcard to me at the above address. NOTES ON BRAITHWAITE'S SPHAGNACE^ EXSICCATE.. By J. A. WiiELDON. Dr. Braithwaite published his great work on The Sphagnacece or Pent Mosses of Europe and America in 1880 : his SpliagnacecE BritanniccB ExsiccafcB appears to have been issued whilst preparing this work. Through the kindness of Mr. H. Beesley of Preston, I have been allowed to examine a copy of the latter which belonged to the late M. B. Slater of Malton. This, on the dedicatory page, is dated in the Doctor's handwriting April 1877, just a month prior to the issue of the circular announcing the publication of his work on the Sphac/nacecB. I am unacquainted with the whereabouts of the other copies, nor do I know whether the specimens in them are from identical gatherings ; but I suspect this is not always so, as in a few instances I find my determinations do not accord with other published ones. A very small proportion of the specimens aj^pears to have been collected by Braithwaite himself, the principal contributors being Messrs. J. M. Barnes, S. Anderson, W. Curnow, Gr. Stabler, J. Sim, and J. E. Bagnall. Some of the examples are too scanty, and, being gummed down, could not be examined with the completeness that is so desirable with these difficult subjects. In some cases, however, loose material in envelopes accompanied the mounted plants. It was interesting to find in the collection a confirmation of Mr. Bellerby's record of Sphagnum havaricnm Warnst. His plant was named by Warnstorf, but the specimen was not returned, and therefore no example was existent in our collections. The plant of Anderson, which I refer to this species, was collected in the same locality as Mr. Bellerby's, viz. Goathlands, Yorkshire. Some of the pages of the volume are blank, having been reserved for varieties which were apparently unobtainable. These, and a few foreign species, or others which do not call for comment, account for the missing numbers in the following list, in which the specimens have been named in accordance with my Synopsis of the European Sphagna published by the Moss Exchange Club.

Prior to the publica- tion of Warnstorf's Sphagnologia Universalis, we had referred many 146 THE JOURNAL OF BOTANY specimens of var. valiilius Cardot to Braithwaite's variety. The records for vice-counties 60 and 61 (and probably that for 48) refer to var. validius Card, and should be so amended. Mr. Horrell in The European SphagnacecB quotes No. 44 of the Exsiccata under both S.Ji mhriafum iind S. squarrosum. There are two specimens from the same locality (Eskdale, Yorkshire, Aiiderson) in Mr. Slater's copy ; I refer both to S. Jimhriatum. In this copy there are also several loose packets collected by Anderson in the same vicinity at different times. Some of these belong to S. Jimhriatum var. laxi- folium Warnst., others — labelled b}^ Anderson ^S*. Jimhriatum var. squarrosulum Anderson, Eskdaleside Moor, 2 Oct., 1875, and S. Jim- hriatum var. rohustior Anderson ?, 18 June, 1875 — belong to S, Jimhriatum var. rohustum Br. On the latter packet Anderson has written *' To say the least of this, it is a good variety ; I have never collected Jimhriatum like it in an}^ other locality." With it is a letter from Anderson to Slater, written from Whitby, June 1875, from which I extract the following: "I send herewith the plant alluded to in my list — I have sent it to Braithwaite and he says, ' I shall send this to Lindberg when I \mte again.' You will see that it is coming into fruit, so that in the course of a month I shall be able to send you plenty of it in that state. I collected it last 3^ear in the same locality, nay from the same identical 9 feet tuft, but not then in fruit. Notice the ascending branches at the apex of the ])lant, and the naiTow border on the stem leaves — altogether different to the ordinary form of S. Jimhriatum. I sent it to Braithwaite as under * No. 1. S. Jimhriatum vsiV. rohustior? Anderson (a sad piece of presumption this).' Look at it well tomorrow and write me fully on it by that day's post." There is no doubt Anderson first detected and even named this variet}^ but did not describe or publish it. Warnstorf's description is excellent, but does not cover all the forms, which are as follows : — («) forma laxum Wheldon. Pale yellowish-green deep tufts 15-25 cm. high. Fascicles distant. Branches elongate, spreading, longly and gradually acuminate, 2-3 cm. long. St. 1. broadly spatu- late, i"14-l'3 long, and usually nearly and sometimes quite as wide. L. lax, broadly ovate-lanceolate 2 X 1"14, erect arcuate with spreading points, sometimes distinctly squarrose. Braithw. Exsicc. No. 44. liight-hand specimen. Eskdale, Yorks, S. Anderson. This plant rivals S. squarrosum in stature ; someone, probably Slater, has crossed out the title S. Jimhriatum., and written in S. squarrosum var. laxum Braithw. I have, however, examined the chlorophyll cells in section and they are situated on the inner surface of the leaf. {h) forma jpycnocladum Wheldon. Shorter (10-15 cm.). Fas- cicles denser. Branches much stouter, more densely leaved, shorter (l;t-2 cm.), suddenly acute, the upper ones erect-patent. The lowest branches are more laxly leaved. Leaves of upper branches imbricate, of the lower erect patent to subsquarrose. Braithw. Exsicc. No. 44. Left-hand specimen. Eskdale, Yorks, Oct. 1875, Anderson. (c) forma comjyactum Wheldon. Grey-green, short (5-8 cm.). Bi-anches cumvilate, arcuate-spreading to dellexed (l|-2 cm., occa- sionally longer). Leaves densely imbricate or with the points only NOTES OS BEAITHWAITE's SPHAGNACE.E EXSICCATiE 147 spreading, sqnarrose in the large capitulum (2-2-3 xO"8-l mm.).

The genus Allophylus was founded by Linnaeus in 1747 in the Flora Zeylanica (p. 58) on the species now known as A. zey I aniens and of which the types are in Hermann's herbarium in the National Herbarium. This is the only species mentioned in the Species I^lantarum in 1753. The genus Schmidelia was also described by Linnaeus, in 1767, in the Mantissa, and as the two are now almost universally considered synonymous, the former must take precedence. In 1859-60 Sender (in Harvey and Sonder's Fl. Capensis, 238) gave under Schmidelia descriptions of five species, and in 1868 my father, in the ^lora of Tropical Africa (i. 420), described twelve species. In 1895 Dr. Radlkofer, in Engler & Prantl. Naturl. Pflanzenfamilien, V. 3. 311, mentions eighteen species from Africa and Madagascar. He relies for purposes of classification and an-angement primarily on whether the leaves are unifoliolate or trifoliolate, and on the chai-acter THE AFRICA1«^ SPECIES OF ALLOPHTLUS 155 of the thvrse. Students of the genus are much indebted to Dr. Radl- kofer for his most careful work, and especially for his paper in Sitz. Bayer. Akad. Wiss. xxxviii. 221-237 (1909) " Uber die Gattung Allopliylus und die Ordnung ihrer Arten." The division into unifoliolate leaves and trifoliolate leaves is not entirely satisfactory : in certain special instances such as A. congolanus Gilg., in vv^hich, although usually trifoliolate, the lateral leaflets are occasionally entirely absent. The division also of trifoliolate-leaved s])ecies into those with a simple thyrse, and those with a branched thyrse, is also occasiorally difficult of application, as in some species — such as, for instance, A. repandus Engl. — a simple and branched thyrse is often found on the same specimen. I note that Dr. Kadlkofer doubts whether this latter species is really specifically distinct from A. alnifolius Radlk., the former being founded on Schmidelia rcpanda Ijaker, the latter on 8. alnifolia Baker. I have careful!}^ examined the types ; in the latter the leaves are cuneate-obovate and blunt, whilst in 8. repanda they are broadest about half way down and acute, and as far as one can judge the species are quite distinct. Dr. Gilg has also made important contributions to our knowledge of the African species ; his papers are in Englers Jalirhnch, xxiv. 286 (1897), where he published 17 novelties, xxx. 348, where are three, and in 1914 in the Botany of the Deutschen Zentral- Africa Exjjedition^ 474 (1911) he published three species. In Journ. Linn. Soc. xxxvii. 136 (1905) I described A. pseudopaniciilatus, A. suhcoriacfus, and A. lat&foliolatus from material collected by Dr. Bagshawe in Uganda, and in xl. 48 (1911) A. chirindensis, from specimens collected by Mr. C. F. M. Swynnerton in the Chirinda Forest. For the discrimination of the trifoliolate species special attention must be paid to the character, consistence, absence or presence of indumentum, and toothing of the leaflets, the absence or presence of ])etiolules, the character of the thyrse, the size of the flowers, and the size and shape of the fruit. The structure of the flower does not seem to be of primary importance for taxonomic purposes. In the following enumeration of the African species known to me, either from herbarium material or description, 1 have thought it advisable to retain as far as possible Dr. Radlkofer's sequence, interpo- lating the more recently described novelties and those here described in their correct positions.

SOME BRITISH RUST FUXGI IGl SOME BRITISH RUST FUNGI. Br Malcolm Wilson, D.Sc, F.L.S., Lecturer in Mycology, University of Edinburgh. In this Journal for 1915 (pp. 43-49) an account was given of the occurrence of several alpine species of the Uredinese ; the follow- ing notes supply additional information on some of these and record tlie occurrence of several others. The British Bust Bungi by W. B. Grove has been of great help in the determination. Melampsora alpina Juel. The uredo- and teleutospore stages of this species on Salix her- hacea have already been recorded (Ber. d. schweiz. bot. Ges. ix. 49) from Ben Lui. A further search was made on Ben Lui on July Ist^ 1915, and the secidial stage was discovered on Saxifraga oj^ijositi- folia, growing at an altitude of about 2500 ft., in close proximity to Salix herhacea, which was bearing young uredospore sori. Only a singh' secidium was discovered, and no spermagonia were found on the leaf, although these were probably present at an earlier date. The aicidial stage, which has been knoAvn as Cceoma SaxifragcB Wint., has been found in Switzerland by Jacky (Ber. d. schweiz. bot. Ges. ix. 49), who proved the connection between the tw^o stages by carrying out infection experiments with both secidiospores and teleu- tosix)res. The Scottish specimen agrees closely with his description. The complete description of the species is as follows : — Spermagonia. Several, epiphyllous. uEcidia, Solitary, epiphyllous, orange-red, at first covered by the epidermis ; spore layer flat ; spores spherical or polygonal, 17-25 x 16-24 ^, wall colourless up to 3 ^ in thickness ; paraphyses colourless, filled with yellow granular contents, ending in a swollen head which is always smaller than the secidiospoi-es. Uredosjjores. Sori small, scattered, rounded, amphigenous, orange- yellow ; spores ellipsoidal or spherical, 19-22 x 14-17 fx, finely echinu- late, contents orange-yellow ; paraphyses abundant, capitate, thick- walled, up to 88 fjL long, head about the same size as uredospores, wall up to 5 ^t in thickness. Teleiitospores. Sori amphigenous, mostly epiphyllous, rounded, up to '8 mm. in diameter, brownish black, covered by the epidermis ; spores flattened or rounded at the apex, rounded and usually diminishing in size towards the base, 2(3-50x9-14/7, wall thin, smootli yellowish brown. ^cidia on Saxifrago oppositifolia L., Switzerland and on Ben Lui, Scotland. July and August. Uredo- and teleutospores on Salix herhacea L., Norway, Sweden, Switzerland and on Ben Lui, Scotland. J uly-October. The discovery of the secidial stage clears up any doubt as to the distinctness of this fungus from M. arctica Rost., a species also growing on Salix herhacea and closely resembling M. alpina in its uredo- and teleutospore stages, but apparently autcecious. 102 TITE JOL^RXAL OF BOTAXT Pltccinia borealis Juel. The secidial stage of this fungus was discovered by Greville on Ben Voirlich (Loch Lomond) in 1821, and this appears to be the only record of this species in Britain. It has recently been found in considerable quantity on Ben Lui (Perthshire) occurring on Thalic- frivn alpinum at an altitude of about 2500 ft. The aecidia are found on the petioles, peduncles, and on the under surface of the leaves on unthickened spots which are pale or reddish yellow on the upper surface. About 8-12 secidia are found in each group. The spores are rather larger than those described by Juel (K. Vet. Akad. Forh. no. 8, 411, 1898), being 20-23 x 17-20 ^. Juel showed by infection-experiments that the uredospore and teleutospore stages occurred on Agj'ostis horealis. He considered that Anthoxantliuin odoratum also acted as a second host, but was unable to infect this species with the aecidiospores from Tlialictrum alpinum. Athough A. odoratum occurs commonly on Ben Lui, no plants were present in close proximity to the diseased Tlialictrum alpinum. It is proposed to carry out infection-experiments to deter- mine whether this species really acts as a second host in this cointry. Pltccinia Polygoni-tiyipari Karst. This was found on 'Polygonum viviporum near Ballinling, Perth- shire, in August 1915. In this neighbourhood P. viviparum is found almost down to the level of the river Tay, and the fungus occurs in abundance on the underside of the leaves, producing pale spots on the upper surface. This rust has been recorded by Greville in 1822 from Mar Lodge and by Trail in 1882 from Braemar, both localities in Aberdeen. The present specimens agree with the descrip- tion given by Grove, except that the uredospores are slightly larger, being 22-28x20-24^. The uredospore and teleutospore stages of Puccinia septentrio- 7ialis are also found on Polygonum viviparum, but this species appears to be confined to higher altitudes where its alternative host, Thalictrum alpinum^ is abundant. The sori of the two species closely resemble each other, but P. septentrionalis is distinguished by the presence of an apical papilla on the teleutospore, while the teleutospore wall of P. Polygoni-vivipari is unthickened. P. Polygoni-vivipari appears to be autcecious and secidia are unknown. The infected plants were growing amongst grass, and an examination of the withered leaves of the previous year showed evidence of their infection by the fungus. No aecidia were found on other species of plants in the close vicinity. Uromyces Oxobrychidis Lev. This was found on Oct. 1914 near Faversham, Kent, growing on cultivated sainfoin. It has not been previously recorded for Britain, and in this case was possibly introduced with seed. The uredospore sori are easily seen on the leaflets, but televitospore sori were only found on the lower pait of the petioles. SOME BRITLSH BUST FrXGI 1G3 Tlie characters of the species are as follows : — ■ Vredospores. Sori ainphigenous and on the petioles, scattered, small, soon naked, pulverulent, rounded on leaf, oblong or linear on petiole, cinnamon- brown ; spores subglobose to ellipsoid, echinulate, cinnamon-brown, 22-24 X 15-22 /L/, epispore 2*8 yu thick with 3 germ pores. Tel euioap ores, Sori similar but darker; spores ellipsoidal to pyriform, hardly constricted, 21-25 X 14-18 ^, minutely warted with a minute papilla at the tip, pedicels short deciduous. On cultivated Oiiobrychis safiva, Faversham, Kent. PucciNTA Hypochceridis Oud. Teleutospores have apparently not been discovered in British specimens of this species up to the present. They were found, however, along with uredospores, on a plant of Hypochoeris radicata^ gathered in 191G near Epsom. They agree closely with the description of the foreign specimens given by Grove, and the minute punctations on the spore wall are clearly visible. P. Crepidis Schrot. has been found on Crepis virens near Ballin- ling, Perthshire, in July 1915. Only uredospores were present on the specimen. This rare species has been previously recorded from Moray, Noi*th Devon, and from Ireland. P. uligi)iOsa Juel. The secidial stage was found on Fctr/ia.'^.sia pahtstris in Glen Sloy, Argyllshire, in June 1915. Up to the present this has only been recorded from Glasgow and Aberdeen. The uredospore and teleutospore stages on Carex Goodenovli have not yet been discovered in Britain. P. major Dietel was found on the lower slopes of Ben Voirlich (Loch Lomond) in June 1915. Only the iecidial stage was present. This autcecious species on Crepis pxiludosa has only been previously recorded in Scotland from Braemar. Erratum. — In Journ.

Manchester University Press & Longmans, Green & Co. 1919. Price 15*. We must confess that so far we have been in no way impressed with the value of the application of mathematical methods to bio- logical problems, nor has a study of this volume in any way caused us to alter our opinion. The book is the result of labours which can only be described as prodigious, but the results do not seem to be in any way commensurate. Ko doubt it would be useful to have "constants" instead of "terms" in botany — if we could cite a certain figure instead of talking of a Itaf as broad or narrow. But is it possible ? we greatly doubt it. The systematic botanist will lind many points of interest scattered through these pages which we should regret to be suspected of undervaluing. Far from it : there are many careful and valuable observations to be discovered by the 164 THE JOURNAL OF BOTANY patient seeker. Let us take as examples the discussion on Plasticity, with numerous instances, nutably that of the *' crimson rambler " of which " when an inflorescence (corymb) is evolved before the buds have reached their full size, the flowers of this branch, when exj^anded, are quite healthy but white : the crimson rambler is, as it were, transformed into a white rambler " : and again, the discussion on the interesting topic of "convergence." As the writer points out, the facts which we try to explain by the theory of " convergent adapta- tion" require two sets of assumptions in accordance with our acceptance of the neo- Darwinian or neo-Lamarckian standpoint ; that all these hypotheses require verification, and until such is forthcoming, " the term convergent adaptation is a delusive screen behind which we conceal the problems which ought to he solved " (author's italics). None of the hypotheses yet brought forward explain the similarity between the fore-legs of Talpa and Gryllotalpa, nor the resemblance between the fruits of certain Myxomycetes and certain G-astero- m3^cetes. We mention these two discussions with the object of sending philosophically minded botanists to the pages of the book itself. B. C. A. W. Botany : a Texthooh for Seiiior Students. By D. Thodat, M.A. Second edition. 8vo. Pp. xix, 524, tt. 230. Cambridge Uni- versity Press, 1919. Price 7s. Qd. It is not surprising that a new edition of Mr. Thoday's textbook has been called for within four years of the publication of the original work. The book was intended primarily for use in connexion with preparation for the Senior Cambridge Local Examinations, and special attention has been given to a clear exposition of certain matters which experience as an examiner had convinced the author were widely mis- conceived or imperfectly grasped. But the book should appeal to a wider circle than is embraced b}'' the candidates for a particular ex- amination. It forms a well- written and well-arranged introduction to the study of botany, and a student who, under a capable teacher, has worked through the matter of its chapters will have a good ground- work in the science. After a short introductory chapter on the general conformation of a plant, the student is led through a series of experiments (forming the chapters of Section I.) in which the plant is demonstrated as a living organism, feeding, breathing, and growing ; Section II. deals with internal structure in reference to the life-processes which have already been described ; Section III., " Ileproduction," describes the flower, its pollination, production of fruit and seed, the dispersal of the seed, its germination, and the growth of the seedling. In Sec- tion IV., " The Classification of Plants." the species, genus, and family are explained and the principles of classification illustrated by a study of members of the llanunculaceae ; and the types of flower and fruit are further studied in a selection of common British families. Sec- tion V. '* Plants in relation to their Environment," begins with a chapter on " fitness," or adaptation, and successive chaj^ters deal with TEXTBOOK FOE SENIOR STUDENTS 165 trees, climbing plants, and water-plants, as common biological types. A concluding chapter forms an introduction to the study of plant- associations. A new feature of this edition is the addition of a supplement on seedless plants, a series of short chapters in which the structure and life-history of Algae, Fungi, Mosses and Liverworts, and Ferns are illustrated by a few selected types. The illustrations are clear and adequate, but the book has been somewhat carelessly produced ; there is no reference on the title-page to the fact that this is a second edition — on the contrary, the back of this page bears the legend " First edition 1915. Keprinted 1919 " ; the pages are not uniform in size and the volume is badly bound. A. B. R.

Those of us who have watched with admiring eyes the progress of State and National forestry in America since Dr. F. B. Hough's memorable European tour of inspection, rather more than forty years ago, can appreciate Dr. Boerker's fully justified pride in his country- men's achievement. The forest statistics of half a continent neces- sarilv deal with large figures. When we read that the United States use annually "90,000,000 cords of firewood, nearly 40,000,000,000 feet of lumber, ] 50,000,000 railroad ties, nearly 1,700,000,000 barrel staves, 445,000,000 board feet of veneer, over 135,000,000 sets of barrel headings over 3,300,000 cords of native pulpwood, 170,000,000 cubic feet of round mine timbers, .... and nearly 3,500,000 telephone and telegraph poles," we are not surprised to learn " that out of 5200 billion feet of merchantable timber once present, only 2000 billion feet are left." Whilst in Germany, where scientific management has brought about the largest annual increment of the national forests per acre, the annual consumption of wood for all purposes — before the recent dehdcle — was only 40 cubic feet per head of the population, in the United States it was nearly 250 cubic feet ! Naturally, since the destruction of the Apj^alachian forests ** the surrounding country has suffered from alternate floods and droughts ; great manufacturing centres have lost their steady supply of water ; harbours are filled with silt from the mountain sides; and fields, once fertile, are covered with sand, gravel, and debris." Thus America, like other lands, has learnt by bitter experience, and has realised " that forest conservation can be assured only through the public ownership of forest resources." The bulk of the mixed hardwood forests of the Eastern States has gone beyond recall, and the reserves of which Dr. Boerker tells the story are coniferous forests at high altitudes in the mountain ranges of the 166 THE JOUKNAL OF BOTANY Western States. They cover, however, 155 million acres — an area one- fifth larger than the whole of France. To place such an area, scattered through eighteen States, under scientific management, to protect it from forest fires and to get from it a revenue of some £700,000 — although that bj no means yet equals the cost of the administration — is no mean achievement ; and this the United States Forest Service have accomplished within the last twenty years. Dr. Boerker's book is a song of triumph ; but it is also a most inter- esting and thoroughly documented exposition of the organization that has reached this result. Although he is no longer himself in the Service, he has had some eight years' experience in it, and has been able to furnish the latest particulars and to make use of many excellent official pictures. His stor^"" is pleasant reading : what he has to tell of protection from fire and from tree diseases is full of lessons particularly important to the Government and people of our own North American Dominion, and also to some extent to us here in our relatively wood-less England. The whole history of forest administration in the United States is one of thoroughness of organization and of liberal far-sighted expen- diture— to some extent upon purely scientific investigations — -which is evidence of true commercial imagination. Such thoroughness necessarily implies an attention to detail, and Dr. Kankin's Manual of Tree Diseases, which we have received at the same time as Dr. Boerker's book, is a fair specimen of the scientific works on economic topics which American workers are now giving us. The author does not deal with injurious insects ; but, whilst the bulk of his work deals with fungal disease, he does treat briefly of sun- scorch, frost, drought, smoke, gas, and mistletoe as causes of disease. The book is an eminently practical one, adapted to the needs of the forester. After four preliminary chapters dealing with those diseases which are general on seedlings, leaves, and roots, the author describes the diseases of twenty-eight leading American trees in the alphabetical order of their common names, ending with chapters on tree surgery and spraying. Bibliographical references — mainly American — are added to each chapter, and a useful list of common names of trees, based upon that of Sudworth, with their scientific equivalents, is also given. The use of text-figures has led to the use of a very heavy paper ; but in spite of this, we cannot help suggesting that something is distinctly wanting, which would add somewhat to the size of the work. The author has relied almost entirely on external or naked-eye characters, so that we doubt whether the amateur will be able to identify the diseases, even though those of each species are brought together in one chapter. A very brief glossary is given in which we note what we consider the vmnecessar}^ substitution of aiciospore, epiphytotic, teliospore and urediniospore for ajcidiospore, ejndemic, teleutospore and uredospore. There is, however, no general outline of the structure of the main groups of parasitic fungi. Curative treatment is described wherever possible ; and if it is depressing to read (p. 138) of "the passing of the chestnut" as a forest tree, owing to the irresistible ravages of Endothia parasitica. MANUAL OF TREE DISEASES 167 the usefulness of the book may be gauged from the fact that a know- ledge of what it contains as to the prevalence of " peckiness," due to Fomes geotropus Cooke, in from 33 to 100 per cent, of the trees of Taxodium in Florida, Louisiana and other States might — not many months ago — have saved our Government many thousands of pounds. Both volumes are well got up ; but publishers should submit the ** jackets," in which it is now the fashion to send out books, to the authors for correction, as two misprints in one brief descriptive paragraph is not a good advertisement of the contents of a volume. G. S. BOULGER. BOOK-NOTES, NEWS, etc. At the meeting of the Linnean Society on May 1, Mr. James Smith gave a demonstration of the various forms assumed by the pappus in Compositce, of which the following is his abstract : — Stating the case for the trichome nature of the pappus in this family as briefly as possible, we have six points. 1. The development of the members of the pappus is either that of a typical trichome (from one epidermal cell) or that of an emergence, such as the spines of a thistle, 2. The structure of the mature pappus is that of a series of hairs which have become fused throughout all or a part of their length, either side by side to give a scale or in a mass to give an awn. 3. The similarity of the setae to the achenial hairs is very marked. 4. The primitiveness of the scabrid seta is in conformity with the evolution of the family as deduced from other data. 5. The predominant type of pappus in the fossil forms is the setose type : no fossil paleaceous pappus is known. 6. The preseDce of a pappus is coiTelated or linked with the presence of achenial hairs, deduction of both characters is also linked, e. g. reduction of the elater hairs of the achene in the Anfhemidere to special epidermal cells is accompanied by reduction of the pappus to the coroniform type. The same applies to some cases in the Gichoriece.. As all the facts adduced in support of the phyllome theory can be easily and adequately explained by assuming that the pappus in certain cases is parti}'' a development of the hairs which Avere inserted on the now aborted but once free calyx-segments, the evidence in favour of the trichome or emergence nature of the organ a Imits of no other conclusion than that which takes the pappus to be hairs, free or fixed, derived in their evolution from the hairs of the ajhene, or sometimes also from the hairs of the now aborted calyx- limb. The subject of tropical plant-diseases is extremely important, seeing that we rely on the warmer regions of the earth for so many r.iw products. Fungi seems to flourish there with great luxuiiance, the warmth and moisture providing most favourable conditions for their development. In his Pliilipjyine Economic-Plant Diseases (Phil. Journ. Sci. xiii. 1918, nos. 4 & 5) Dr. Otto Keinking says : " There are as many destructive plant diseases in the Philippine Islands as there are in the United States, if there are not more." In this work, the author has followed on the 168 THE JOURNAL OF BOTAWY lines of Thurston Cooke's Tropical Diseases ; he has arranged them in alphabetical order under a list — also alphabetical — of the host-plants. The method evidently has commended itself to the practical grower as a ready means of ascertaining what is already known as to the diseases to which any plant is liable ; but it involves a good deal of repetition as the same or nearly related fungi occur on various hosts, and gives little assistance in recognizing the nature of any disease not previously known. Special attention is given to curative methods. Several diseases due to Bacteria are carefully described, such as the bud-rot of Coconut and the Citrus canker, but the large bulk of those tabulated are caused by microfungi. Very little attention has been paid to the larger fungi which do serious damage in the tropical woods as elsewhere ; insects too are left out of account. So far as it goes, however, the record is very complete and provides a useful guide for a much wider field than the Philippine Islands.— A. L. S. The Kew Bulletin issued in March (1919, nos. 1, 2) is mainly occupied by a List of " Food and Fodder Plants " by Mr. J. H. Holland, in which are given the chief countries of production with details as to uses and other notes of interest and full references to Avorks quoted. " The natural families first in importance for plants of this nature are placed first in order " — an arrangement the possible advantage of which hardly compensates for its obvious inconvenience to those who are accustomed to follow a certain sequence of orders. The latest issue (vol. viii. n. 2 ; 24 April) of the Journal of Oenetics is entirely devoted to botanical matters. E. S. Salmon continues his account of experiments made at Wye College '* On Forms of the Hop {Humulus Lupiilus L.) resistant to Mildew {Sphcerofheca Humuli (DC.) Burr." ; Bateson gives the first of a series of '* Studies in Variegation " in which he deals with '* Reversal in Periclinal Chimseras " as exemplified in Euonymus japonicus lati- foliusy Coprosma Baueri var. variegata, and three Pelargoniums — the paper is accompaniod by two of the admirable coloured plates w^iich have always been a feature of the Journal : S. C. Harland treats of the " Inheritance of certain Characters in the Cow-pea ( Vigna sinensis) " ; and 0. Winge, of the Carlsberg Laboratory, Copenhagen, whites " On the Relation between number of Chromo- somes and number of Types in Lathyrus especially." The Essex Field Club has issued a neat volume, the sixth of its ** special memou's " (price not stated) on the Mycetozoa, containing *' a short history of their study in Britain, an account of their habitats generally, and a list of species recorded from Essex." The matter in the little volume was delivered by the author, Miss Lister, as two presidential addresses, at the annual meetings of the Club in 1917 and 1918 ; to these she has added a Hst, with descriptive notes, of the species found in Essex and tables of those for certain other counties. A plate contains three species found first in Essex — Badhamia folii- cola, B. pojmlina, and Comatricha fimhriata — for a description of which we are referred to p. 50 ; it will however be found on the back of the table of contents. 109 NOTES ON BRITISH EUFHKASIAS.— I. Br H. W. PuGSLET, B.A. About twenty years ago I began to pay attention to the genus Ewphrasia and collected a number of forms, most of which were sent to the late Mr. F. Townsend for determination. In later years I have continued to augment my collection of these plants, both British and Continental, with the intention of working them out in detail, when opportunity offered, with Wettstein's Monograph and the original descriptions. The fortunate occasion has not yet arrived, but as Mr. W. C. Barton was desirous that I should add my criticisms to the rather numerous contributions sent this year to the Botanical Exchange Club, I have lately made a partial survey of my gatherings in conjunction with the plants sent to the Club, and the succeeding notes embody some of the results that seem of special interest. In reviewing the European forms of the true Eiq^hrasicB, it must be borne in mind that the points of distinction between the alleged species are relatively trivial, and that one species only, E. officinalis L., was commonly recognized by British botanists j^rior to the advent of Townsend's account in this Journal in 1897. This work accurately applied to the forms then known in Britain the views of Wettstein, and marked a great advance on the treatment hitherto accorded here to the genus. But it is perhaps regrettable that Townsend always followed so closely in Wettstein's steps, for a peiaisal of the Mono- graph suggests that more has yet to be done in the grouping of the forms recognized as species and in establishing their natural affinities. The bases of segregation of Wettstein's three series, ParviflorcSy GrandiJiorcB, and Angustifoli(S, seem open to serious criticism as primary group-characters, although possibly no better means of dis- tinction can be found among plants whose differences are so slight. The validity of the elongation of the corolla-tube after anthesis, or the reverse, seems especially doubtful, and at best, is rarely an obvious and unmistakeable feature. My observations lead me to doubt its constancy even in the single species, JE. Rostlwviana, as represented in Britain ; and I notice that Mr. Bucknall tacitl}^ ignores it in British Eiiphrasice, published as Supplement I. to vol. Iv. of this Journal (1917), by referring to E. campesfris, an undisputed member of the Grand i^orce, the plant that he names var. neglect a, which he admits has the corolla-characters of the Earvijlorce, A paper that deserves consideration in connection with the British Eyebrights is that by M. Chabert, " Les Euphrasia ^q la France," in the Bulletin de VHerhier Boissier for 1902. This author recognizes about a dozen species as French, with a number of varieties, and reduces the rank of some plants that Wettstein and Townsend treated as species. Euphrasia minima Jacquin. This species was first brought to notice as a British plant by Miss Helen Saunders in a short note in this Journal for 1909 (p. 30), JoUK^AL f)F BuTANY. VOL. 57. [JULi, 1919.] O 170 THE JOURNAL OF BOTANY in which its discovery on Exmoor is reported and its name published on the authority of Wett stein. A month later a further note was contributed (Z. c. p. 74) by Mr. C. E. Salmon, who stated that he had found the same plant near Porlock in 1898, and that it had been referred by Townsend to E. nemorosa. These notes were followed in the succeeding May (/. c. p. 165) by a lengthy paper by Mr. Hiern, wherein an interesting account of E. minima is given, with a full synonymy and a detailed description of the plant as seen on Exmoor. A figure, with dissections, is also furnished. E. minima has subse- quently appeared in thi British list in Mr. F. N. Williams's Pro- dromits, where E. horeaUs Towns, is united with it, and in Mr. Buck- nail's British EuphrasicB. In the last-named work fresh forms from the Lake District, North Wales, and Monmouth are described as varieties nana Rouy and arhuscula Bucknall. It may readily be concluded from the pre-Linnean citations in Mr. Hiern's paper, which show that E. minima was one of the earliest forms of the genus to be distinguished, that it is a plant of a relatively distinct facies and one characteristic of the Alps. Its usual form is well depicted by Boccone — "E. lutea, minima, alpina, sub- rotundo folio nigricante " ; and as such it is often common in Switzer- land at an altitude of 5-7000 ft. I first met with it in 1896 on the Erohnalp, in Canton Schwyz, where it grew in myriads, completely covering large stretches of mountain slope. Since that date I have collected it in various localities both in the calcareous and the granitic Alps, the last occasion being in the Blumenthal above Miirren in 1911. The Pennine Alps produce forms somewhat different from that prevalent in Central Switzerland, the very compact form described by Townsend as E. capitulata, and the form pallida of Gremli, with larger, whitish flowers, both occurring in the Saas Valley. The Swiss forms of this species, however, all show the same essential characters, which they possess in common with the varying forms of the adjacent regions, extending to the P3T:'enees and to the Balkans, which have been united under E. minima by Wettstein and other authors. E. minima seems to be one of the " aestival" species of Wettstein, which are scarcely represented in Britain, except by E. foulaensis and E. scotica. Its stem is erect and normall}'' simple, and never more than sparingly branched, its leaves, which are rarely numerous, are t3q:)ically subrotund and very obtuse, or at least always distinctly broad, its spike is relatively dense, its small, yellow corolla has subequal lips, the loAver but little deflexed, and its capsule is emarginate and fairly broad. This may be seen from a perusal of the varied exsiccata in Herb. Mus. Brit, and Herb. Kew, but it is worthy of note that the sheet of plants in the National Herbarium at South Kensington from Jacquin's Herbarium, referred to by Mr. Hiern, consists of seven specimens, none of which is E. minima : one is Bartsia OdontiteSy one Euphrasia salishurgensis var. ciipreay and the remainder apparently E. Bostlcoviana ! The Exmoor plant, as compared with the Continental species, is slenderer and, when well grown, very much branched, with flexuous, ascending rather than erect stems, numerous small, narrow leaves, which are never strongl}'' pubescent, laxer spikes, and the lower lip NOTES ON BRITISH EUPHRASIAS 171 of the corolla distinctly longer than the upper one. On seeino- Mr. Salmon's original siDecimen several years ago, and those placed by Mr. Hiern in Herb. Mus. Brit., I at once dissented from the identifi- cation, quite failing to recognize in them the Swiss plant with which 1 was familiar, or to understand Wettstein's reasons for such a deter- mination if he was furnished with adequate specimens. A recent examination of the abundant and well-dried material contributed by the Rev. E. S. Marshall to the Exchange Club has confirmed me in this view, and I find that a similar opinion is held by Mr. H. Stuart Thompson, who is familiar with the Alpine E. minima and remarked in 1912 in Suhalpine Plants (p. 233) that Exmoor was an unlikely spot for E. minima and that the British Museum specimen was not very typical. I indeed fail to see any real resemblance to E. minima in a well-grown individual of our British plant, excepting its small yellow corollas and emarginate capsules ; and the opinion of Townsend and that of the unnamed authority referred to by Miss Saunders, who suggested the name ** E. curta var. glahrescens^'''' seem to be more in accord with the plant's affinities than the determination of Wettstein. If it be admitted that this Exmoor plant cannot be regarded as conspecific with E. minima Jacq., as seems impossible if a standard of species approaching that of Wettstein and Townsend is followed, it becomes necessary to reconsider its position in the genus. It is evidentl}" a well-defined form, growing over a considerable area, and is remarkable as the only yellow-flowered Euphrasia found in Britain. The features that differentiate it from E. minima do so almost equally from E. scotica Wettst., which has lately been suggested with some show of reason to be inseparable specifically from E. minima. The slender stems and narrow leaves of the Exmoor plant recall E. gracilis Er., but this differs widel}^ in its strict habit, with suberect, central branching, and also in its differently coloured corolla and narrow, subtruncate fruit. E. nemorosa Mart, and E. curta Wettst., especially the latter, show somewhat similar branching, but both of them are much robuster plants, with stout stems, larger and broader leaves, white or bluish flowers, and narrower and less emarginate fruits. The only remaining British Euphrasias -with which a comparison is necessary are E. horealis Towns, and E. occidentalis Wettst. Both of these are robust forms, the former with large, broad leaves, and white or more rarely blue flowers in a dense spike, and the latter a dwarf plant, much branched, with short stems, broader and partly glandular foliage, and small, white corollas. The Exmoor plant thus seems separable from all other known British forms. Furthermore, none of the foreign species described in Wettstein's Monograph or elsewhere, so far as is traceable, can be considered identical with our plant. The closest resemblance is seen in E. varia- hilis Freyn (Sched. Fl. Austro-Hungaricse, iv. p. 55 (1886)), w^hich, when dry, is not readily separable from small individuals, with simple stems, of the Exmoor plant. But E. variabilis does not become much branched when well developed, and the lips of its yellow corolla are subequal as in E. mini7na. in which it is merged by Wettstein. E. exigua Renter and E. pumila Kerner are also somewhat similar, o2 172 THE JOURNAL OF BOTAJfT but both of them are at most only sparinglj^ branched. Of the remaining two species of Euphrasia bearing yellow flowers, the Andalusian E. WiUkommii Freyn is easily distinguished by its robust, compact habit and broad, deeply cut leaves, and the alpine E. Christ it Favrat by its very large, show}^ flowers. The Exmoor plant therefore appears to be an unnamed form, and as there seems no evidence that it is especially connected with either of its apparently nearest allies, E. gracilis, E. nemorosa, and-E". curta^ it can hardly be treated as a variety of one of these, and it becomes necessary to regard it as a new endemic species, intermediate in general features between E. gracilis on the one hand, and jE/. nemorosa and E. curta on the other, but peculiar for its 3^ellow corollas and broad, emarginate capsules. It is proposed to name the plant E. confusa, and it may be diagnosed as follows : — Euphrasia confusa, sp. nov. E. minima Hiern in Journ. Bot. 1909, 165, non Jacquin nee aliorum. Icon. Journ. Bot. /. c. tab. 497 a, \\.i E. minima. Exsicc. E. S. Marshall, nos. 4440 et 4443, ut E. minima \ Caulis suberectus vel adscendens, gracilis, 2-20 cm.

In collibus regionis Exmoor dicta (alt. circa 400 m.) in comitatu Somerset et forsan in Devon Angliae invenitur. In view of the very full description of this jDlant furnished by Mr. Hiern (/. c.) a further diagnosis in English seems superfluous. It may be mentioned, however, that the cauline leaves of well-grown plants are scarcely ovate, though this term may perhaps be used in respect of weak examples such as those originally gathered by Mr. Hiern at Great Cornham. And it is apparently chiefly in luxuriant specimens that the teeth of the floral leaves become dis- NOTES OX BRITISH EUPHRASIAS 173 tinctly aristate. It may Be added that Mr. Hiern's figure is drawn from weak plants and does not portray the intricate branching that is prevalent in well-grown examples of the species. Of the variety nana mentioned by Mr. Bucknall (Brit. Euphr. p. 23) I have seen no material; of var. arhuscula (l. c. p. 24) authentic specimens in Mr. Barton's herbarium from Patterdale and Moel Siabod seem to me unconnected with the Exmoor plant and referable for the most part to £J. curta var. piccola Towns. Mr. Pearsall's plant from Bigland, similarly named, shows dis- tinctly larger flowers, and I think is probably a stunted form, such as is occasionally seen in hilly districts, either of E. Kerneri or eglandular E. brevipila. I may add that I collected a EupTirasia near Keswick in 1903, with simple stem, broad, obtuse leaves, and very small, whitish flowers, which I referred at the time to E. scotica, but which in the dry state is not readily distinguishable from true E. minima. Euphrasia hirtella Jordan. It is a curious coincidence that this paper, which has been largely devoted to contesting the identification of the yellow-flowered Eye- bright of Exmoor with the Swiss E. minima, should be concluded by an introduction to the British Flora of E. hirtella, which often grows in the Alps with E. minima and occasionally forms hybrids with it. The basis of this new introduction is a set of specimens which I collected on a rocky pasture near Llanberis, in North Wales, in September, 1917. The plants attracted my attention owing to their robust, erect, unbranchecl habit, and their shaggj^ grey-green foliage ; and at the time of gathering them I omitted to notice the glandular character of the hair-clothing and sujDposed that, as they bore quite small flowers, they were referable either to E. curta or E. latifolia. On recently examining the specimens, I immediately saw that the hairs were glandular as in E. JRostkoviana, and that the habit and small flowers, in conjunction with this feature, brought them to E. hirtella Jordan, a species that I have collected at Arolla and else- where in Ihe Pennine Alps. The National Herbarium contains an authentic French example of E. hirtella, received from Jordan himself, as well as other good exsiccata that are clearly conspecific, and a comparison of these and the Kew collection with my Llanberis material reveals no essential differences. The chief divergence is that the British specimens, the tallest of which is but 12*5 cm. high, do not show the distant lower leaves referred to in Jordan's original descrijjtion (Renter, Comptes rendus des travaux de la Societe Hallerienne, iv. p. 120 (1854-6)) — a feature readily seen in most of the foreign exsiccata. But this does not appear to be a constant character, for it is omitted from Wettstein's diagnosis, and in undoubted examples that I collected at Arolla in 1906 the lower internodes are scarcely longer than those of the Llanberis form, as seen in 1917. The nature of the Llanberis habitat — a barren, cool and wind-swept situation — may be conducive to the plant's dwarf growth there, or it may prove that it constantly differs in this respect from the Continental type and is varietally 174 THK JOFEXAL OF BOTANY separaLle. It is also probable that in the British form the lower leaves are relativel}'^ narrower. The occurrence of M. hirtella in North Wales might not mi- reasonably be expected from its Continental distribution. It is found in Central and Northern Spain, in the Pyrenees, in the French, Italian, and South-Western Swiss Alps; and eastwards, it is said to extend from the T^'rol through the Balkan Peninsula, Transcaucasia and Siberia to Chinese Mongolia. In France it reaches the depart- ment of Haute-Loire and the mountains of Auvergne. In connection with E. hirtella it seems desirable to allude to IE. fennica Kihlman, included as British in Mr. Bucknall's British J^uphrasicB (p. 27). Of this plant there is an authentic sheet in Herb. Kew from Kihlman himself (PL Finlandise Exsicc. no. 354, as E. hirtella Jord. var. fennica Lind. fil. (£!. fennica Kihl.)), and I possess other good Finnish material. It is a form somewhat inter- mediate between U. hirtella, to a variety of which it is apparently reduced by Kihlman, and E. Bosthoviana, to which it has been likened by Wettstein. Of the former it possesses the strict, erect habit, but it is taller and more slender, with long lower internodes and a tendency to branch about the middle of the stem. Its lowest leaves are easily caducous as in E. hirtella, but its corolla is much Lii'ger, 7-8 mm. long, with the lower lip distinctly longer than the upper one and with broader segments, and hence approaching the iiower of E. Rostkoviana. On the whole, however, there seems good ground for placing it under E. hirtella, to the type of which it seems nearer than some Asiatic examples that have been so named. I have had no opportunity of seeing Mr. Druce's original Exmoor specimen determined by Dr. Lindman, but those collected in that district io 1917 and 1918 by Mr. Barton and the Pev. E. S. Marshall do not a])pear to me to be identical with the Finnish form but rather modifi- cations of E. Mosthoviana. E. hirtella may be described as follows : — Euphrasia hirtella Jordan ex Renter in Comptes Rendus Soc Haller. iv. 120 (1854-6) ; Wettstein, Mon. der Gattung Euphrasia, 175 (1896) ; E. tatarica race E. hirtella Rouy, Fl.

Stem strict and erect, of variable size but usually robust, 3-25 cm. high, simple or occasionally with one or few erect branches towards the base, more or less purplish, pilose (especially above) with long, whitish, flexuous and partly glandular hairs. Leaves svibopposite, dull green, up to 8 mm. long or larger in vigorous plants, clothed M'ith whitish bristles and abundant long, flexuous, unequal glandular hairs ; the lowest leaves obovate, or in the British form narrower and cuneate below, obtuse, with few obtuse teeth ; upper cauline leaves ovate or broadly ovate, obtuse or subacute, with 3-6 more or less acute teeth on each side ; floral leaves broadly ovate or triangular- orbicular, acute, with 4-8 acute or acuminate but not awned teeth on each side ; nerves prominent below when dry ; lower leaves often NOTES ON BRITISH EUPHRASIAS 175 readily caducous. Spike very dense above and never much elongated, with the imbricated floral leaves more or less covering the fruiting calyces. Calyx clothed like the foliage, with lanceolate teeth, scarcely accrescent in fruit. Corolla small, 5-7 mm. long (5 mm. in British form) along the back, white, streaked with violet and with a yellow spot in the throat ; lower lip but little exceeding the upper, with narrow, emarginate lobes. Capsule oblong-ovate, truncate or slightly retuse, nearly equalling the calyx or slightly exceeding it, usually shorter than its floral leaf, margin long-ciliate. E. Mrtella is readily distinguishable from all other British Eye- brights, except H. Bostkoviana Hayne and E. Vigursii F. H. Davey, by the long, flexuous glandular hairs that usually abound on its stem, leaves and calyx. E. Bostkoviana, which is furnished with similar but sometimes less abundant hau*-clothing, is generally a widely different plant. Considering its usually larger size, it is of slenderer habit. Its stem is ascending rather than erect, flexuous rather than strict, and though not much branched, yet clearly more so than in E. hirtella. Its corolla is very much larger, commonly 9-11 mm. in length, with the lower lip conspicuously longer and broader than the upper one and the tube eventually elongating. Its capsule, also, differs in being broader, more elliptical in form, and generally dis- tinctly emarginate. E. Vigursii is normally still slenderer than most of the forms of E. Bostkoviana, with smaller foliage clothed with proportionately shorter and less unequal glandular hairs, and the corolla and capsule as in E. Bostkoviana, except that the former is commonly violet in colour instead of white. E. campestris Jordan can hardly be confounded with E. Tiirtellay being a slender, much branched plant, with small, narrow leaves clothed with shorter glandular hairs, and very large corollas with elongating tube. I have placed Llanberis examples of E. Mrtella in the National Herbarium. NOTES ON SOMERSET PLANTS FOE 1918. By the Eey. E. S. Marshall, M.A., F.L.S. (Concluded from p. 154.) Solanum nigrum L. 3.

White and I spent the last week in June and the first in July botanizing in East Norfolk, dividing our time bc?t\veen the coast village of Hemsby and the delightful liamlet of Ran worth. Owing to the War and consequent military activity upon the eastern coasts, it was not easy to allay suspicions whilst botanizing, and upon one occasion near Winterton we were closely questioned and the contents of our vasculums were examined. Fortunately these showed that we were not in the habit of fraternising with aliens ! It was a happy coincidence, too, that our maps had just been stowed away safely in inner pockets and that the awkward bulge in my venturesome companion's coat — denoting a camera — did not attract attention. I'lants that appear to be additions to Norfolk are distinguished by an asterisk. Flora=^W. A. Nicholson, Flora of Norfolk, 1914. Fumaria Borcei Jord.

This we found in one or two fresh stations some miles away from its well-known Caister locality, occurring south of Hemsby north of Winterton as well as between these two places. It grows intermingled with A. arenaria, as it does at Caister, but it may be recognised, even at a distance, by its long tapering panicle invariably tinged with purple. At a closer view the more lanceolate glumes also readily distinguish it. The former more obvious character, which was borne out in some hundreds of examples examined, I do not see mentioned in Babing- ton, Hooker. Hayward, etc. It is suggf^sted that A. halt lea is the result of the crossing of A. arenaria with Galamagrostis epigeios^ but the latter plant does not grow anywhere in the immediate neighbourhood and, as far- as the Norfolk stations are concerned, there is nothing to support this theoi'y. Mr. A. Craig-Christie has an interesting note upon A. haltica in this Journal for 190S, p. 800, his observations bearing upon the Ross Links (Northumberland) plant, and I thoroughly agree with his view that it is a good species allied to, but well separated from, A. arenaria and not a hj'-brid. On the Continent, however, where the plant is no doubt more widely distributed than in Britain, the consensus of o]nnion is seemingly in favour of its hybrid origin, Lange (Danske Fl. 68, 1886) being one of the few who treat it as a good species. Marsson (Fl. Neu-Yorpomm. 563, 1869) goes so far as to divide the " hybrid " into a. suharenaria ( = ^1. haltica Link etc.) and /3. suhepigeios, an arrangement followed by Aseherson and Graebner (Syn. Mittel.

To judge by the meagre list of hepatics recorded for Radnor YI. 43 in the Census Catalogue of British Hepatics compiled bv Mr. William Ingham (1913), few counties have been less explored for hepatics, so I was glad to examine a collection made last April at Aberedw by Mr. Harry Bendorf of Manchester, whom I have inter- ested in the study of these plants. In the Census Catalogue only 19 species are recorded ; I have been able to identify -13 in Mr. Bendorf's collection, which he informs me was made withm a radius of two miles from Aberedw. I have no doubt a further exploration of other parts of the county would very much increase the number enumerated, especially if the more alpine parts of the county were searched — Radnor Forest attains the height of about 2000 ft. Amongst the most interesting of the discoveries is Lejeunea cavi- folia (Ehrh.) var. heterophylla Carr. As Macvicar remarks (Handb. Brit. Hep. p. 419) this is a distinct-looking plant ; the somewhat distant leaves, with lobule minute or obsolete distinguish it at once from the type ; although there were plenty of perianths on the plants I was not able to find a single stem with the short male branches which are to be found on the monoicous type. Should this prove to be dioicous I should have no hesitation in considering it a distinct species, Lejeunea heterophylla (Carr.) Pears. MS. This name may perhaps be criticized by Prof. Stephani. In Journ. Bot. 1894 (p. 328) I described a species, Frullania microphylla, which had up to then been considered a variety of F. Tamarisci {F. Tamarisci yar. onicr ophy I la Goitsche). Stephani (Sp. Hopat. 568) lists it as Frullania micropJiylla Gottsche, and adds a footnote, " The plant is correctly published by Gottsche, since it was distributed in G. k R. Hep. Ex., tlie name Pear.son as author (who first described the plant) is therefore not admissible." In my Hep. Brit. Isles I described it as F. microphylla (Gottsche) Pearson, which I think is correct. Lopliocolea spicata Tayl. is another interesting record for the county. I am sorry this characteristic name has been supplanted by that of L. fragrans Moris & De Not., on the authority. of Schiffner & Mueller ; Stephani, who draws up his description of L. fragruTis from the actual plant, holds that they are distinct, and I agree with him. L. spicata has not the fragrant smell which distinguishes the genus. It is one of our rarest species, having a very limited distribu- tion. For a long time it was only known from the south of Ireland, afterwards it was found in Cornwall and Wales very sparingly, and later by Mr. Macvicar in Scotland ; it has been recorded from the Channel Islands and north of France. Many years ago, when the only known stations for this rare hepatic were the south of Ireland and Cornwall, the late George Stabler sent me a specimen from Wilson, labelled ** near Conway." I made several visits to Conway and searched the likely glens about there in vain : later I found that Wilson had collected plants at Trefriw, a matter of 10 miles away 194 THE JUL'lt:NAL OF BOTANV from Conway. I took the first opportunity I had of visiting that delightful spot, and to my joy I met with the plant in quantity on the rocks near the Falls. Wilson had the reputation of being very reticent as to the definite locality of the mre plants he collected, and when he noted on his specimen '* near Conway " — a station ten miles awa}^ — I felt he had left open a wide field for search. Marchesinia Mackaii (Hook) Gray, is also a good find and would indicate that other species usually peculiar to the limestone would be found, if looked for.

Bentham stated in his Handbook of the British Flora that this plant grows " In stony heaths, pastures and bogs, fields and waste places " — a comprehensive group ; Hooker, in The Studenfs Flora, said '* Roadsides, commons, etc. ; ascends to 1100 ft. in Yorkshire "; Babington, often more accurate than either of these greater botanists in his first-hand knowdedge of British plants, gave " Gravelly and heathy places." Mr. J. W. White, whose notes on habitats and similar matters in the Flora of Bristol are the most carefully com- piled of an}^ " Flora " known to me, gives " Native ; on commons and in open woodland. Frequent, but very thinly distributed. There are seldom more than one or two plants at a place." Until last year, wdien my work took me daily into the woods of N. Somerset, I had been much struck, especially about Blackdown, Mendip, by the truth of Mr. White's remarks on this pretty little St. John's Wort in the large area treated. But last summer and autumn I found the plant in Somerset on various occasions in con- siderable quantity on " rides " in woodlands, and especially on "rides" and green paths in larch and mixed woods, such as at Wrington Warren (larch 30 years old), Court Hill (Clevedon), King Wood above Cleeve, T^^ntesfield Plantation, and to a less extent in Leigh Woods. Just as the recently discovered and rapidly extending Juncus tenuis keeps rigidly and uniformly to the rides and paths in Leigh Woods, so does H. humifusum, as far as my observation goes, rarely stray far from the paths in any of the above woodlands. In like manner Erodium maritimiim, when growing inland in N, Somerset, frequents either the bare limestone rock, as at Goblin Combe, or the shoi't grassy paths on hills, as above Axbridge, Rowberrow and Wrington, and much used " rides " in limestone woods such as those above Clevedon Court and Tyntesfield. It actually grows on the modern brick paving outside the engine-house and saw-mill at Tyntesfield. It is interesting to note that whereas all the above-mentioned woods are upon Carboniferous Limestone *, Coste says of H. humi- fusum in France " Champs et coteaux sablonneux des terrains siliceux dans presque toute la France ; rare dans le Midi." Joseph Woods in his Tourisfs Flora also gives merely " Gravel and sand." Taking * Though not always of the same Carboniferous Limesftoaie Series ; and parts of certain of these woodlands are on other formations. 19G THE JOURNAL OF BOTANY Britain as a whole, I believe this species is more often seen on sandy or red gravelly soil than on limestone, but evidently it likes the close turf though sometimes sandy soil of the rides in woods on limestone. On the Continent, e.g. in Switzerland and the Jura, it appears that this plant is sometimes found in damper and more cultivated places e. q. in arable ground. Two modern authors mention " Fields after the crops, clearings in woods " ; and another botanist speaks of " Damp fields, clay soils, cultivated and cleared, clearings in woods, unequally spread" (Grodet, Flore du Jura, an excellent work). In conclusion, it seems that a plant one has usually associated with dry hill-sides, sandy commons, and open woods, or road-sides near them, may have its erratic and sparse distribution markedly effected by the agency of man ; and JBentham's habitats probably referred to the plant throughout its known geographical range, and not only to that in the British Isles. Such, indeed, was apparently the case in regard to all the plants in the HandhoGh, a point worth drawing attention to, and not hitherto properly appreciated by myself. SHORT NOTES. Female Flowers iiy Plaistago lanceolata. Some interest- ing observations have been made this spring on plants growing wild in Kew Oardens, and the following seem worth recording : — Plants of Plantago lanceolata are common in the grounds round the Her- barium ; and amongst grass which has not j^et (Maj- 28) been cut, several have been observed with the stamens in all the flowers reduced in size, the filaments very short, and the anthers producing no fertile pollen. All the spikes on each plant have their flowers in a similar state of functional unisexuality through reduction of the stamens. The flowers, like those of a normal Plantago, are protogynous, the styles and stigmas of the lower flowers being the first to appear. When these have become brown and shrivelled the j^ello wish- green (not cream-coloured or very pale yellow) sterile anthers appear, but since they have extremely short filaments the stamens are not nearly so conspicuous as in normal spikes. The ovaries are fully fonned and the ovules are developing into seeds. Growing near the abnormal plants, and subjected to the same external conditions, are some with quite normal flowers and inflorescences. The abnormal unisexual state must be due to inherent causes affecting the entire plant indepen- dently of external conditions, and may be compared with the reduc- tion of the stamens in the small-flowared form of Glechoma hederacea. In the Botanical Bulletin (afterwards the Botanical Gazette), i. 45 (1876), is recorded a plant of P. lanceolata which had flowers without a trace of stamens or anthers. The styles and stigmas developed normally at first, but '* soon began to bend down so that the stigma entered the tube of the corolla and soon the whole style was coiled up in the corolla tube, remaining there for a day or more in some instances, when it resumed its erect position." Nothing like this has been observed in the Kew specimens, in which the styles drop off when the seeds^are partly formed. — W. B. Turrill. SHORT >'OTES 197 Yew ox Oak. On May 31st, I saw in Leigh Woods, near Clif- ton (N. Somerset), a small shrubby Yew-bush about a foot high growing upon a rather young Oak tree : I do not remember having noticed before a Grymnosperm epiphytic upon an Angiosperm. In Leigh Woods the Yew is doubtless native, as it is in most of the woods on the Carboniferous Limestone of North Somerset, and also on the hmestone cliffs and screes at Cheddar, Burrington Combe, Bourton and other combes. The plant now reported grows by a path within half a mile of the rocky ridge where PolygonaUim officinale and Lilies-of-the-valley grow together — fortunately by no means extinct, as was feared by Syme (Engl. Bot. ed. 3, ix. 180). This year many of the Solomon's-Seal are no taller than the Lilies-of- the-valley, and some are shorter. — H. S. TnoMPSOJf. The Beodeick Heebaeitjm (see Journ. Bot. 1904, 295). Through the kindness of Lord Midleton I have recently examined the above at Peper Harow. The collection is bound in the form of a volume with the inscription " Tho. Brodrick 1672 " upon the title- page. There are 138 leaves (c. 17"xlO") with several plants upon each, British, exotic and garden species being mingled ; unfortunately many have been damaged by insects, and not a single plant is either localized or dated. The Latin name of the period — and in these changeful days it is comforting to note that Mentha cardiaca of to-day was the identical Mint prescribed for heart affections in Elizabeth's time — and the quaintly expressed English name is appended to each specimen, and there is a full index at the end of the volumes with page references. — C.

Botaniqne Generale, revue et corrigee par J. CosTANTiN, pp. XV, 619, tt. 260. Tome II. Botanique Speciale remaniee et augmentee par J. Costantin, pp. xx, 743, tt. 326. Masson : Paris, 1918. Price 30 fr. The present edition of the late Prof. Van Tieghem's well-known smaller textbook of Botany follows closely the plan of earlier editions. The editor. Prof. Costantin, does not supply any prefatory note or introduction indicating the changes or additions for which he is responsible, but these do not appear to be extensive and the book remains the expression of Van Tieghem's views as to the pre- sentation of the science and especially on methods of classification. The first volume deals with morphology, including structure, and physiology. In the first chapter a general account is given of the plant-body in two sections, the first entitled morphology, the second physiology, and a similar plan is adopted in the following chapters 198 THE JOURNAL OF BOTANY* dealing in succession with the root, stem, leaf, and flower. While this method has the advantage of correlating structure and function, it leads to a somewhat disjointed study of plant-physiology and involves some repetition. The chapter on the flower is followed by one on " the development of the Phanerogams," in which the deve- lopment of the ovule, the seed, and the fruit, germination, and the growth of the adult plant from the seedling are considered. The formation of the egg and the life-history of the plant in the Vascular Cryptogams, the Muscinese and the Thallophytes are studied in the next tliree chapters. To emphasize the diiferences in the origin of the " spores " in the several great groups, the term spore is restricted to those which develop to form an individual like that from which they were produced. The spores of Ferns and Mosses are designated respectively, diodes, or spores of passage from the asexual to the sexual stage, and tomies, as the life-history of the plant is cut into two very unequal parts at the stage of their production. The relation between the Gymnosperms and Vascular Cryptogams is recognised, the pollen -grain being in reality a microdiode and the mother-cell of the female prothallium a macrodiode. The second volume is a systematic study of .the plant-kingdom. Two subkingdoms are recognised, Arhizophj^tes, including Thallo- ph^^tes and Muscinese, and Khizophytes, including Vascular Cr}'3)togams (Exoprothallees) and Phanerogams (Endoprothallees). The Thallo- ph^^tes contain two classes, Fungi and Algae ; the Myxomycetes form the first order of the Fungi and the Bacteria are regarded as a famil}^ of the Blue-green Algaf. Phanerogams comprise two classes, Astigmatees or Gymnosperms and Stigmatees or Angio- sperms. The former has four classes, Pteridosperms, Natrices with motile male cells, including C^^cads and Ginkgo, Vectrices (Coniferie\ and Saccovulees (ovule enclosed in an ovary which forms a sac with no style) — including Welwitschia, Eijlicdra, and Gnetiim. The Angiosperms have three classes. Monocotyledons, Liorhizal Dicot}^- ledons, and Dicotyledons. The second is a very unnatural group, comprising two orders. Grasses and Nympha^aceje ; the Grasses are regarded as having two cotyledons and the water-lilies are classed with them owing to the similarit}^ of the mode of development of the piliferous layer of the root. The method of the grouping of the families of Dicotyledons is widely different from that of other well-known systems. Special stress is laid on the details of the structure and development of the ovule, wdiich Van Tieghem had studied exhaustively. The resulting system may interest the student as an exercise in taxonomy, but cannot be regarded as an advance towards a natural system or a contribution to the study of phylogeny. A. B. 11. Standard Cyclopedia of Horticulture, Vol. VI. S-Z. with Supple- ment, pp. 3013-3639, figs. 3516-1056. Edited bv L. H. Bailey, 1917. The present volume is the last of the imposing work edited by L. H. Bailev, the dovcn of American scientific horticidturists, who is STANDARD CYCLOPEDIA OF HOKTICULTrEE 199 much to be congratulated on its completion. In the Supplement he makes a characteristic statement : — " To spend five years in a review of the vegetable kingdom, with all its marvels and its unsolved problems, is in itself a great privilege. If in addition one may see the applications to the desire of man, may hold associations with several hundred enthusiastic and competent correspondents, may have relations with the commercial and financial questions involved, and may at the same time catch some glimpse of the reaches of evolution and feel a new contact with the earth, the making of a Cyclopedia of of this kind becomes not a task, but an experience in life .... The Editor is well aware of the shortcomings of the volumes and he would like to do the work all over again for the delight of it." With such a spirit as driving-force, the rapidity with which the volumes have followed one another ma}^ be understood. The articles in the present volume and the general and specific descriptions are of the same high quality which has throughout characterized the work. Besides being of a more scientifically exact type than is common in horticultural books, they abound in points which, though referring principally to American horticulture, are ver^'^ suggestive to British growers. In the six volumes over 3000 genera and 12,000 species have been fully described : more than four hundred collaborators have been employed on the work. There is a " Cultivators' Guide " to the articles, and a very complete index to synonyms, vernacular names and miscellaneous references not in alphabetical order in the body of the work. In the Supplement is a section with the American-sounding title of " Finding List " ; this contains the names in common use in North America with their equivalent in the Cyclopedia. Herein is to be found a statement of the American Joint Committee on Horticultural Nomenclature, whose aim has been " so far as is practicable to secure the standardizing of a single botanical name, together with a single ver- nacular or common name for every tree, shrub, and herbaceous plant in the American Horticultural trade." Such a committee is much needed in this country, where we suffer from the confusion and inconvenience resulting from the abuse of different names for the same plant or the same name for different plants. We gather from the article on Welwitschia that Dr. Bailey is in favour of long- accepted usage rather than priority as making for stability. A page is devoted to new combinations made during the progress of the work. These refer principally to varietal names, but the following specific combinations occur : — Cissus oligocarpa (Lev. & Van) Bailey; Selenium aromaticum (Hook.) Bailey; Hosta Fortunei (Baker) Bailey; H. longipes (Franch. & Sav.) Bailey; Lactuca Bourgcei (Boiss.) N. Taylor ; LWiocarpus densiflora (Hook. & Arn.) Rehder ; L. cornea (Lour.) Eehder ; L. glabra (Thunb.) Rehder ; L. thalassica (Hance) Eehder; Maurandia Lojihospermiim Bailey; Hhododendron candidum (Small) Rehder; R. IcBtevirens 'RehCiQY ; R. aiisfrinum (Small) Rehder. Many new combinations in Ryrus, Friintis, Statice were published in JRhodora, 200 THE JOUllNAL OF BOTANY xviii. (1916). No new species are described and very few new varieties. The whole work is a model of its kind — printing, figures, plates, and get up being worthy of the valuable horticultural and botanical matter contained in the volumes. J. K. 11. BOOK-NOTES, NEWS, etc. At the meeting of the Linnean Society on June 5, Mr. H. N. Dixon gave the following abstract of his paper on Mosses collected on Decep- tion Island, South Shetlands, by Mr. James C. Robins. Deception Island is in lat. 63° S., long. 60° 30' W., closely adjoining the Ant- arctic continent (Graham Land). It has been very little visited, and until the present century only two plants — an unnamed moss and a lichen — had been observed. Two mosses were collected there in the second French Antarctic Expedition (1908-10) by MM. Gain and Gourdon. The present collection consists of eight species, one known from most of the colder regions of the world, one hitherto only recorded from the South Orkneys, three of general Antarctic distribution, two hitherto known only from the Antarctic continent, and one new species. The- interior of the island is a vast crater, into which the sea has irrupted, and is about 5 miles across. Connected with this is a small lagoon, some 500 yards in diameter ; Mr. Robins describes it as giving no bottom at 200 fathoms, and as fed by warm or hot springs from the volcano. The whole crater would seem, in the middle of extreme glacial surroundings, to afford an almost unique example of an isolated biological area, and would appear to deserve a careful survey as regards its fauna and Hora, especially in so far as concerns that of the warm springs and the lagoon fed by these. Sir Frank Crisp, who was born at Bungay, Oct. 25, 1843, died at his residence, Friar Park, Henley-on-Thames, on April 29, where his gardens, and especially his rock garden, were among the most remarkable in the country. From 1881 to 1906 he was Vice-Presi- dent and Treasurer of the Linnean Society, at whose Annual Meetings his financial statements were looked forward to with interest, on account of the amusing comments with which his figures were inter- spersed. He was also Hon. Secretary of the Royal Microscoj^ical Society from 1878 to 1889, to whose Journal he contributed papers dealing with practical microscopy. The Irish Naturalist for March contains an interesting paper (with plates) by Dr. George H. Pethy bridge on heterocarpy in Ficris hieracioides. A Correction. — Mr. Moore calls our attention to a curious error in our review of The Life and Letters of Sir Joseph Hooker, where (p. 132, 1. 2 from bottom) " Lyell " should be substituted for " Banks." The phrasing of the letter quoted is somewhat obscure, but as Banks died in 1820 he obviously could not have been seen by Hooker in 1836. We may take the opportunity of correcting a mistake in the book itself (ii. 275), where it is stated that "a fourth edition of the Studenfs Flora " appeared in 1897 ; the last (third) edition appeared in 188'i. 201 THE GENUS FAGARA AS BEPKESENTED IN THE SoUTH AfRICA:N HeEBARIA. Br Ikez C. Verdooen, Division of Botany, Pretoria, The genera Fagara (Syst. ed. 10, 897 ; 1759) and Zanthoxylum (Hort. Cliff. 487 ; 1737) were founded by Linnaeus, who appears to have used the number of parts in the perianth for separating them : in Fagara the flowers are 4-merous, in Zanthoxylum 5-merous. Thunberg (Fl. Cap. 141 ; 1823) followed Linnaeus, and when describ- ing the South African species placed them under Fagara, DeCandolle (Prodr. i. 725 ; 1824) sunk Fagara under ZanthoxylMrn, which genus he placed in Miitacece, and in this he was followed by Oliver (Fl. Trop. Afr. i. 304; 1868). Harvey (FI. Cap. i. 445; 1860) adopted the same view, but placed the genus in Xanthoxylew, although later (Gen. S. Afr. PL ed. 2, 45 ; 1868) he put it under Butacece as a separate tribe. Bentham and Hooker (Gen. PL i. 297 ; 1862) also combined the genera under Zanthoxylum in Hutacecd : Engler, however (Engl. & Prantl, Pflanzenfam. iii. 4, 115 ; 1897), reverted to the two Linnean genera, and this arrangement has been adopted by all subsequent authors. All the Soutli African species which Wight and Amott included under the genus Rhetsa were placed by Engler (/. c.) in the genus Fagara under the section Macqueria, which is characterized by having 4-merous flowers. Engler (Bot. Jahrb. xxiii. 149 ; 1896) describes two species from Pondoland, F. Bachmannii and F. multifoliolata, I have not seen these, but none of the material which has passed through my hands agrees with the descriptions. The specific name capensis will have to stand for the plants called Xanthoxylon capense and Thunhergii in the Flora Gapensis as it was the first name used by Thunberg. In the Flora Capensis Harvey divides the South African speci- mens into two species with a possible third. Xanthoxylon capense Harv. is separated from X. Thunhergii DC. on the fact that the petioles are unarmed ; I have found that this character is not constant. Through the kindness of the Director of the South African Museum, Cape Town, I have had the opportunity of examining Ecklon and Zeyher's specimens quoted by Harvey, which are mounted on sheets written up by Harvey. On the leaves of one of the specimens (^E- Sf Z. 921) quoted as X. capense there are decided spines. I have noticed on specimens growing in the garden of the Division of Botany, Pretoria, and on many herbarium specimens, that while some of the leaves are armed, others on the same tree are devoid of thorns. Sim points this out on a label attached to one of his specimens ; the coppice shoot is armed with numerous spines, of which there is no trace on the older foliage. Mr. T. E.. Sim (^Forests and Flora of Cape Golonyy 155) is of opinion that the species in Fl. Capensis can all be reduced to one variable species, and my examination of the material in the South African herbaria supports this view. Specimens collected from different localities differ in general appearance, but I have not been Journal of Botany. — Vol. 57.

Two specimens (not in flower) collected by Galpin on the mountain -tops at Queenstown at an altitude of 4700 ft. (Galpin 2560 & 2561) differ from the other specimens examined in the leaves being more or less membranous. This however, as pointed out by Mr. Galpin himself, is probably due to the altitude and the fact that the specimens were growing in the shade of rocks and almost pros- trate on them. The material of the specimen (^. 'r MYCOLOGICAL NOTES.— lY. By W. B. Grove, M.A. I. Phi'llosticta and Phleospora. The species assigned to tlie form-genus of the Coelomyeetes named Plileospora have long afforded a curious ground of controversy, the point in dispute being whether there is a true pycnidium or not. Both sides of the dispute have been hotly maintained : Klebahn says that Phleo^pora TJlmi has no pycnidium, and therefore he places it in Scptogloeum. As in most controversies both sides are right : the shield is golden on one side, silvern on the other. The fact is that the answer at which one arrives in considering this question depends upon the state of development of the fungus under examination. In the early stages of growth, some at least of the species of Plileospora have a pjxnidium, in the latter stages it ma}^ be nearly or completely wanting. But this is not all ; the spores produced by the same h}Tnenium may change in character also in a remarkable way. The same little black dot on a leaf, obiter visuni, would be placed, accord- ing to its age at the moment of observation, in Phyllosticta, or in I^hleospora, or in Seplogloeum, or even in Leptothiirium or Septoria. The differences between the first two form-genera appear very considerable. In JPhyllosticta there is a complete, thin, all-round pycnidium, formed of delicate closely interwoven (plectenchymatous) hyphse, at the summit furnished with a small round pore about which the cells are often darker in colour, while the spores are unicellular, oval-oblong, usually small, and most often provided with two polar oil-guttules : in Plileospora the spores are elongated and vermiform, often pluriguttulate, occasionally 1- or 3-septate, and the pycnidium in its finished state is merely a shallow cup with a wide opening, edged by a narrow margin. Yet the former can change by degrees into the latter, and finally, if all tmce of the pycnidium had vanished, it would undoubtedl}' be considered a Septogloeum. Specimens oiPhleospora 0^y«c«wM^Wallr. when closely examined show, intimatelj'^ mixed among pycnidia which accoi-d Avith the description of that species, others belonging to Phyllosticta, and in fact indistinguishable from Fhyllosticta monogyna Allesch. except in having slightly smaller spores. The appearances are exactly what would be seen if the same p^^cnidium, which at first when small produced the Phyllosticfa-spores, afterwards from the same pro- liferous stratum (enlarged) began to produce the Phleospora-spores, which then by their size and abundance burst tlie pycnidium open and finally left it cup-shaped. Tlie loose cellular structure of the wall is of identically the same character in both ; two pycnidia, one of each kind, can be found in close contact, and all the stei:>s between can be traced in the sections. Moreover, the spores of the PJiyllosticfa-sisige vary continuously in size. Allescher gives the size of the spores in his P. monogyna as 6-8x2|yu; in my specimens most of the spores measured 4-6 X 1-1^ /^. It may therefore easih^ be surmised that Pliyllosticta crutceqicola Sacc. (Syll. iii. G) is nothing but a still earlier state, in MYCOLOGICAL NOTES 207 which the spores are smaller (2|-3 x 1-1| /u). A great deal of the confusion which exists in the synonymy of the Coelomycetes is due to the failm*e to recognize the fact (easily demonstrated on hundreds of species) that the spores may gradually increase in size, as well as alter in colour and complexity, as the fungus advances in age. Thus all Di-plodia-sipores pass through the states of being (1) hyaline and continuous, (2) pale-brown and continuous, and (3) darker brown and septate, sometimes also increasing in size j^ar I passu SiS they change in form and colour. In the first state they have been called Macro- phomtty in the second SphcBvopsis, and in the third Diplodia, the choice of genus being merely the accident of the occasion, the matm'ity of the fungus, or the amount of time bestowed by the observer on its investigation. Thus the actual specimens of Dr. Ellis which are recorded in British Journals as MacropJioma Fraxini yield, when more deeply probed, both Spliceropsis and Diplodia spores m the same pycnidia ; and similarly I have proved by the examination of a long and fine series of examples that Phoma Pinastri Lev. and SpJicBvopsis Ellisii Sacc. are merely growth-states of Diplodia Pinastri Grove. The same remark applies, with the necessary limitations, to the three spore-sizes of the Pliyllosticta mentioned above, and one may be forgiven for suggesting that there is no reason why Pliyllosticta Crattegi Sa,CQ.= Cheilaria Gratcegi Cooke (in Grevill. xii. 25) should not be considered to be the same species just before passing into the Phleospbra-?,\j3L^e, when the upper part of the pycnidium is bursting into lacinise. The Phleospora-stage would then be a later one, when the elongated spores are being produced, but this is mere surmise. There is little, if any, diiference between the way in which these two kinds of spores appear successively on the same mycelial bed, and the way in which, in the Rusts, the same spore-bed will produce in succession uredospores and teleutospores, and equally in both cases each kind of spore may appear alone on its spore-bed, unaccompanied by the other. The necessity then arises, when only a few specimens are available, of describing each spore-form as if it were an indepen- dent species, as was done on such a large scale in the Uredinales, but also in both cases alike a wider knowledge, based on more numerous examples, enables the evil to be remedied. If then, in studying this injurious disease of Hawthorn hedges *, •we take the indications given above as proving that Phyllosticta monogyna is the fore-runner of Phleospora Oxyacanthce, we should expect to find a similar state of things in connection with other Phleosporas, and that is exactly what we do find. For Phleospora Aceris Sacc, is accompanied by Phyllosticta Platanoidis Sacc, which at one of the intermediate stages looks like a Lepto- thyrium, and has been called L. Platanoidis. In the same way Phleospora JJlmi Wallr. is accompanied by a species of Phyllo- sticta which apparently has not received a name, and a similar but * To help in the investigation of the fungi which grow upon the common Hawthorn, the author will be grateful if mycologists will send to him, at the University, Birmingham, any species of Cytospora which they may find upon that host, with notes of the locality and mode of occurrence. 208 titp: .touhnal of i?otaxt stranger case is seen in what has usually been called Septoria Poda- grarice Lasch. This latter common fungus is frequently accom- panied on the same spot by Phyllosticta j^gopodii Allesch. The *' Septoria" really has a thin pycnidium, but this soon disappears, so that some mycologists have wished to place it in Cylindrosporium, a genus which should not have the slightest trace of a pycnidial wall. To do so would be a serious error, confusing together two unlike things ; it is really a Fhleospora, since the genus Septoria should be confined to those species with elongated spores in which the thin pycnidium pei-sists in its complete form up to and after the dispei-sal of the spores. All these fungi appear to develop at a later stage into species of Mi/cosplicercdla. Klebahn proved that PJiJeospora TTlmi is the pyc- nidial stage of his Mycosphcerella TJlmi (Jahr. Wiss. Bot. 1905, p. 492), Jaap did the same for P. Oxyacanthw and M. OxyacanthcB (Bot. Ver. Brand. 1907, p. 15), while P. Acer is is often accompanied bv an immature Pyrenomycete, which has the external characters of a Mycosptlicsrella, but contains only an oily mass of globules — this is presumaljly J\I. sep>torioides (Desm.). There are other similar cases, 6. g. Phyllosficfa JEyopodii and Phleospora Podagrarice are almost certainly the early stages of M. u3Egopodii. The consideration of the var^dng forms of these pycnidial stages, like those of Phomopsis (Keiv Bulletin, 1917, p. 49), shows how closely the various groups of Fungi enumerated in the third volume of Saccardo's Sylloge are connected together ; how necessary it is, therefore, to have a term (Ccelomycetes) which shall include them all, and, finally, how gi-oundless is the attempt made to distinguish between them by calling the spores *' sporulae " in one group, and ** conidia " in the other. It is, of course, desirable that some mycologist with the requisite facilities should cany out a series of cultures to verify these state- ments, but it must be admitted by all that, when a parasitic fungus occupies a definite "spot" (caused by the mycelium) on a leaf, the sj)ore-forms seated thereon may usually be taken as the equivalent of a pure culture, whenever the sequence of events occurs over and over again without variation in the same order, saprophytics and other intruders being then naturally out of the question. II. Sph^eultna inteemixta (B. & Br.) A^"D its Allies. In 1852 Berkeley and Broome described, in the Annals and 3Iagazine of Natural History^ a fungus with scattered perithecia on dead twigs of Kose to which (because it grew mixed with Sphceria fuscella) they gave the name Sphceria intermixta. In 1866 Cooke recorded, in one of the early volumes of this Journal, a similar fungus on dead stems of Puhus to which he gave the name Sphceria ahhre- viata. The name was derived from the habit of the fungus, which has its perithecia mostly not scattered, but arranged in short stmight black rows of three or four, placed longitudinally on the stem. Saccardo, in his Sylloge, vol. ii. p. 187, assigned the former species to the genus Splicer ulina, and recorded it on living bark of Euhiis. He ascribed to it, what neither Berkeley and Broome nor Cooke had MYCOLOOICAL NOTES 209 mentioned, " ascos diu in globum fasciculatim junctos," adding that he suspected S. ahhreviata Cooke to be a very closely allied species. Against this was to be set Cooke's statement that his ahhreviata had brown spores ("pale brown when mature"), whereas the spores of S. intermixta are always perfectly hyaline. Now it happens that round Birmingham there occurs, on small dead shoots of Ruhus^ in considerable quantity, a fungus which accords exactly in external appearance with Cooke's species, and has its asci cohering at the base into a persistent globose fascicle, but its spores always entirely free from colour. Both the species mentioned above were described by their authors as having triseptate spores, Saccardo says of S. intermixta '* spores 3-4-septate." One concludes that Cooke's description of the colour of his spores was merely a slip of the pen, and that the two forms are alike in the asci and spores, but differ in the arrangement of the perithecia. This is not all. On further examination of these specimens on Muhus it will be found that, while the younger perithecia contain triseptate spores, showing here and there also a fourth transverse septum, yet some older ones will disclose (mixed with those just mentioned) many larger spores having five or even six septa. There is every reason to believe that the former of these states is Meta- sphceria sepincola (Fckl.) Sacc, on dead stems of Rosa and Riihiis ; whether it is the Sphceria sepincola of Fries is doubtful. The later 5-6-septate stage may be considered with equal probability to be the same as MetasphcBria hracJiyttieca (B. & C.) Sacc, on Bosa, the details being exactly as described so far as the short diagnosis goes, and especially the description of the spores as like those of Patellaria (Lecanidion) atrata (see in Grevill. 1876. iv. 146), But there is still another development to be considered. Recently I found at the Botanic Gardens, Birmingham, on dead twigs of Rosa damascena, a fungus which externally was very like S. intermixta, having somewhat scattered perithecia, oblong sessile asci collected into a persistent globose fascicle, and all the other points of that species, except that it had larger spores with 5 to 7 septa and one or two of the loculi occasionally divided by a thin but unmistakably longitudinal septum. This can evidently be nothing but a later and more evolved form of S. intermixta. Cooke records his >S^. ahhreviata as accompanied by Hendersonia Rosce. Most mycologists would now call this H. Ruhi, altliough an examination of many specimens on both Rosa and Ruhus has furnished me with absolutely no morphological criterion by which they can be distinguished. Exactly in the same way the fungus on Rosa damascena was accompanied by what is usually called Hendersonia Rosce, though in this case the triseptate spores characteristic of this species occasion- ally become 4-septate and, moreover, showed frequently one or even two plain longitudinal septa, so that it became technically a Camaro- sporium, as many Hendersonias do. In fact this increase of septation as the spores of Coelomycetes and Ascomycetes become older and longer is a very common phenomenon, though its occurrence and its fundamental influence on future taxonomy is only just beginning to be recognised. 210 THK JOUKXAL OF I30TANT The conclusion at which one must arrive is tliat *S'. ahhreviata (Cooke) and S. inter mixta (B. & Br.) are distinguished solely by the arrangement of their perithecia (a difference which future obser- vations may entirely remove), and that they probablv constitute one species (^S. interinixta), occurring indiscriminately on Rosa and Rubus, and having in addition, on Rubus, a var. abbreviata (Cooke). The fungus on Rosa damascena may then also be described as a variety or form of S. intermixta. It w^ould be a negation of all the rides of common sense to place it, where it technically belongs, in Pleospora, ^CatJia?nfiia, for it does not resemble the species of that section at all, while it does in every waj' recall to mind S. intermixta. Saccardo's method of arrangement, though wonderfully useful and in fact indispensable (without it chaos would have reigned in the Sphairiaceie), must not be forced upon us in disregard of obvious affinities.

BARBABEA BltTXARlS IX ENGLAND 211 BARBAREA RIYULARIS IN ENGLAND. By the Ret. E. S. Marshall, M.A., F.L.S. About the middle of June Mr. W. D. Miller brought me fresh specimens of a Cruoifer which he had found gi'owing plentifully in a ditch on the west side of a bj^-road dividing the parishes of Cossino-- ton and Chilton Polden (dis. 8), v.c. 6 N. Somerset. The very small pale yellow flowers and crowded pods (erect when full-grown) at once suggested B. stricta ; and a comparison with my only two herbarium- sheets so named showed a complete agreement. One, from Thirsk, Yorks (Herb. Syme), was gathered by Mr. J. G. Baker in June, 1854 ; the other, from a ditch side, Upton-on-Severn, Worcs., was collected by Mr. S. H. Bickham on May 29th, 1905, in good flower and young fruit. On June 26th Mr. Miller (who had also observed one plant on a peat-moor " drove," near Edington) took me to the Cossington locality, where it is unquestionably native. On July 8th I found sevei-al hundred plants, apparently the type, in good finiit, on a broad, peaty " drove," about | mile S.E. of Edington Junction. The Thirsk plant was confirmed by Svante Murbeck and A. B. Jackson as B. stricta Andrz., and the Upton one by A. B. J., who wrote : — " Yes ; a most distinct species ; and obviously nothing to do with B. vulgaris, under which Bentham placed it as a variety! " I fully agree as to its specific rank ; but, happening to refer to Rouy & Eoucaud (Fl. de France, i. 198-9), I was much surprised to find that our British plants have apparently been misnamed ; some translations from their account of the two species concerned may be helpful.

Suec. ed. 2, p. 207, which we have not seen from Fi-ance, though it has .been rejwrted from several stations, through confusion with the form B. rivularis, and especially with the var. longisiliquosa, can be separated by the following characters : — Plant biennial ; stem solitary. Radical and lower leaves with small pairs of lateral lobes, evidently shorter — even, as a rule, the uppermost — than the breadth of tlie terminal lobe, sometimes with lateral lobes none, or much reduced. Flowers small, in long, dense racemes. Pods 212 THE .TOURTfAL OF HOTAXT longer and thicker than in the form rivularis, crowded, appressed to the axis or convergent, mucronate by the thick, blunt, ver}^ shoi-t (| to 1 millim.) style. Seeds oval-oblong, blackish. Plant has a harsh, sharp, non-nauseous taste." Syme's figure (Engl. Bot. ed 3, Plate 122) fairh^ well represents the type of £. rivularis. Babington describes the pods as short, and the pods as adpressed, with a subulate point. I have not seen any Thames-side plants ; but probably the}^ are, as a rule, the type. With the exception of one or two specimens brought home, the Cossington gatherings, having pods up to a full inch in length, evidently belong to var. longisiliquosa, as do both my herbarium- sheets. The young pods are often arcuate-ascending, and resemble those of B. arcuata (which seems to me a fairly good subspecies of B. vul- garis') ; their slender, subulate points are quite as long as in vulgaris. The petals (as Syme says) exceed the sepals by about a quarter; their claw is long and slender, and their limb, which starts from the tips of the sepals, is squarish. I only observed solitary stems in the ver}^ numerous individuals seen. In his Novitise Fl. Suec. ed. 2, p. 207 (1828) Fries gave only one station — in wet s|x)ngy places near Skarby, in Scania — and describes his plant, for which he preferred the name B. i^a^'viflora, as there was another *' jB. vulgaris, sfricfa''^ (apparently var. sylvestris Fr.) ; but of course this cannot stand. The expression " petalis linearibus," if correct, should help to distinguish B. sfricta Andrz. from B. rivu- laris, in which the linear claw abruptly terminates in a short, squarish limb. In Mantissa, iii. p. 77 (1842) Fries reluctantly gave up the name B. parviflora, and observed : — " B. stricta est certe biennis. Majo floret B. vulgari praecocior; saj'for cruclus, sed non acri- acerhus"'' [i.e. as in B. vulgaris']. Having no suspicion that oui plant was wrongly named, I did not apply this test. It is, of course, possible that the real B. stricta Andrz. may occur in Britain, as it grows in Scandinavia, &c. ; but, on present evidence, this seems rather unlikel3^ B. 7'ivularis appears to be a Avestern species. I could see no hairs on the few unopened buds ; but they were probably too far advanced. ALABASTRA DIVERSA.— Paet XXXI.* By Spencer Le M. Moore, B.Sc, F.L.S. 1. Miscellanea Africana. ERICACEiE.

As the rule for spelling these very essential botanical terms is still somewhat vague and casual, while writers using the above orthography are frequently snubbed by would- be purists, it may be of interest to place on record the history and various modes of writing these terms ; they have undoubtedly come to stay as convenient conventions in Floral Terminology, and it is time that some ruling was accepted in ths matter by English writers. For example, in a recent publication (^Botany of the Living Plant, 1919, p. 221), Professor Bower retains the present spelling as distinctive and suitable, for the sake of uni- formity, though acknowledging that the etymology may be faulty. In support of Prof. Bower's usage, continued from his well-known Practical Botany (in several editions, 1894, 1902), it may be stated at once that there is much more to be said for this method etymo- logically than for the popular variant gynaeceum ; though it is again possible that to others both methods of spelling may be equally o^^en to criticism. It may be also admitted that it is ridiculous to spell two such homologized expressions on a different plan ; while to have to explain such subtle distinctions to a class of students with ordinary common sense is a])t to make a teacher of elementary botany both look and feel a fool ; there can be no doubt that the retention of such complexities of terminology in a science already over-burdened with vestigial and traditional phraseology encourages a disrespect for the pedantries of pseudo-science. Grood terms are necessary, and there should be no difficulty about their correct presentation. The first appearance of the two words now considered dates from an essay written in Latin {Linnaea, i. 433) by J. Poeper, so far a classicist, and the words are given quite clearly and definitely with their proposed etymology (p. 437), as androeceum^ ex a.vr\p et dt/w-os (without accents), and (p. 438) gynaeceum^ ex yvvr\ et o\i:o% : "Hie verticillus foliis foemineis efformatus baud inepte forsan gynoecei nomine designari posset." To the apostle of priority the terms ar^ thus established once for all on a reasonable basis, and there is no more to be said ; the expressions are good words, fairly euphonious, conceived in correlated form, i. :d GY^oKCI^^r 223 by Lang (1912) returns to t\\Q gynaeceum (diphthong) with androe- cium (p. 483). In the Glossary of Botanical Terms (B. D. Jack- son, 1916) gynaeceum is recorded as derived from ywaiKelov, ignoring Roeper, though the Latin gynecium and the English (Gen. Plant.) form gynoeciiim are included as variants. The Oxford Dictionary, unfortunately restricted to books published in this country, with characteristic ineptitude in botanical matters gives gynoecium (diph- thong) as "the usual but incorrect form oi gynaeceum'''' (diphthong), "having been supposed to be from ohloi', house, and under the influence of this notion androecium has been formed as its correla- tive " — an interesting example of literary stupidity, all the points being incorrect ; since, as already indicated, androecium is so far the elder twin of the pair, the Avord is legitimately formed from okos, and it was the usual form in this country only up to 1875 or so. Apart from the question of the oe and ae, it would also appear that continental writers and modern botanists have largely followed Sachs, retaining the -eum of Roeper (1826), while English writers tend to the -iumoi Bentham (1832), The difference between e and i is quite optional, and both may be found in latinized terms, though the presumable association with -olKthn- might lead to -iU7n as nearest in intention (Bentham). Apart from any philological bias, it may be noted that while -eum as a suffix is rare in botany (except in adjectives) ; -imn, whatever may be its etymological origin, is a commonplace ending of many words in general use, of the type : — archegonium, antheridium, archesponmn, ainphitkecium, sporan- gium, gonidium, sporidium, &c., and it may be taken as a convenient and generalized termination. From such a standpoint of mere litemry convenience the emended spelling androecium and gynoecium, as established by Bentham and Hooker (Gen. Plant.), omitting the unnecessary diphthong t^^pe, may be established as sufficiently legi- timate to satisfy all claims, and the words as written in the heading of this note are entitled to stand permanently. To return to the -sum of Roeper may be satisfying to the more pedantic ; the atti- tude of Bentham is good enough for any English botanist ; but the use of ae instead of oe, is not only distinctly wrong but extremely foolish. BIBLIOGRAPHICAL NOTES. LXXVI. Henry W. Bubgess's ' Eidodendeox.* This work, described on its singularly ugly title-page as " Eido- DENDHON : Views of the general Character and Appearance of Trees, foreign and indigenous, connected with Picturesque Scenery, by H. W. Burgess : London, 1827," is, so far as the plates are concerned, of no botanical importance and hence rarely finds a place in botanical libraries. There is, however, a copy in the Department of Botany, and the book presents a few points of bibliographical interest which may as well be put on record. 224 TIIK JOUHXAL OF liOIANV The work is a folio volume containing 54 plates, of which a list is given, and a portrait of the author ; it was published in numbers, each apparently containing six plates. Both title-pages — there is one preceding the plates — are dated 1827, but this for the whole work is manifestly incorrect : there are tAvo dedications, one to George IV., the other to William IV. — from the latter it would appear that Burgess held some official position, as he speaks of having ** trusted to show that the office of landscape painter has not been idly bestowed upon [his] Majesty's faithful and obedient servant." A notice by James Main in Loudon's Mag. Nat. Hist. (ii. 52 ; March, 1829) shows that 12 plates (two numbers) were then published ; Loudon {A?'boretum, i, cxci) says that nos. 5 and 6 were published in 1833. It is in connection with these numbers that such botanical interest as the work possesses will be found. Prefixed to the volume is an essay extending over 26 folios, headed in very small capitals ** Botani- cal Diversions I," followed by a large title " Amoenitates Querneae." It includes a comprehensive account of the Oak in literature, history, poetry, and commerce : there is however no indication as to its author- ship, although it was evident that it was written by a competent person and that Burgess had nothing to do with it beyond issuing it with his book. Dr. Daydon Jackson in his useful Guide to the Literature of Botany (1881) attributes it to Gilbert Burnett (1800- 35), but at this distance of time does not remember w^hence he obtained this information ; this will however be found in the Arhorettim, as already quoted, where it is stated to be " by the late Professor Burnet " {sic). It is, as has been said, a very complete account : Loudon (ojp. cit. iii. 1722) refers to it as "a very curious and elaborate production — not so well known as it deserves to be ; the history of the more celebrated Oaks is elaborated with much care, and the work as a whole should be consulted by anyone who may be interested in the subject.'' It may be noted tliat Burnett indicates various names not taken up in the Index Kewensis and proposes (fol. 3) three new ones for species alread}^ characterized : — " Q. navalis [vel pedunculata]. The Ship or Naval Oak ** Q. regalis [vel sessiliflora]. The Royal or Bay Oak " Q. Homer [vel pubescens]. The red- wooded, durmast, or downy Oak, James Britten. SHORT NOTES. New Variety of Tolypella glomerata. In examining a large number of specimens of Tolypella glomerata, we have come across some plants which, in the more rounded shape and the red colour of the oospore, exhibit a variation in the direction of T. nidi- Jica. The decoration of the membrane is also somewhat intermediate in character between the two species, frequently showing smooth intervals between the granular lines. The points of diiference from typical T. (jloinerata seem sufficient to justify the separation of the plants referred to as a distinct variety for which we propose the SHORT XOTES 2*2o name ERYTHEOCAiiPA : — Oospora late-ellipsoidalis c. 850-400 /a Ion ga, coronula exclusa, 300-850 ^ lata ; evythra, aut rubro-fulva aut rubida. Membrana lineariter-granulata, saepe intervallas leves inter lineas granulatas exhibens. The localities from which we have identified the variety are :— - Anglesey, I^lyn Coron (J". E. Griffith); Leitrim, Lough Melvin (i?. Ll.Praeger) ; E. Donegal, L. Magheradrmnman {G. E. B.-W). In typical T. nidijica the oospore is much larger than in any form of T. glomerata, and the membrane is wine-red in colour and quite destitute of decoration. — J. Geotes and G. K. Blllock- Webstee. Htpeeicum humifusum (p. 195). I possess a long analysis of the soils and habitats of this plant in Lincolnshire, and the}^ practi- cally agree with Mr. H. Stuart Thompson's notes and Bentham's, but methods of ecological research have been carried further. It is truh^ a woodland species, but not of the young thrusting growths, rather of the decaying stage, passing into Calluna moorland. The decay of our Pine- woods between a.d. 800-1400 — i. e., during the vine-growing period for wine — and later of our sandy Beech-woods, has practicalh' ended this species with us generally, for it is only 4 to 6 : 1 = very coimnon, 2 = common, 3 = fairly common, 4 = rather rare, 5 = rare, 6 = very rare. It should always be most care- fully noted ecologically when not on mooilands, if it is in the open ; and even on them when with other species as Pyrola minor, Equi- setiim sylvaticum, and E. hyemale, as a proof of woodlands. Dr. F. A. Lees once told me that the plant was specially a bank species in West Yorkshire, I suppose on account of the heavy rainfall. It is not so in this dry county — at least I have not a smgle record in over 600 notes. It may be fairly classed as a lime hater, though it is often not so geologically, only ecologically ; for the limey rocks where it is found are acid sandy above, or the upper-root soil is neutral from endless rain-wash and plant-decay in weathering — a sj^ecies of moory humid soils in both cases. Here is a fifty years' soil list for Licoln- shire — all the soils more or less sandy or peaty-decay moory : Lower- Lias-Clay 6 ; Lincolnshire-Limestone 6 ; Corn Brash 6 ; Spilsby- Sandstone 3-5; Chalky-Boulder- Clay 5-6; Sandy-Glacial-Gravel 6 ; Purple-Boulder-Clay 6^ Plateau- Gravel 5-6 ; Old-Piver-li ravel 3-4; Modern -River- Gravel 6 ; Fresh- Water- Alluvium 6 ; Blown-Sand 4-6, rarely 1-2 : quite fifty per cent, of the records are from this soil. Its habitats are : Calluna moors (85 per cent.) 1-4; Commons 2-4; Open-woodlands, rides, paths, scrubs and falls, 2-6 ; Pine woods 1-4 ; Oak-birch 3-4 ; Kough-pasture and golf-links, 5-i5 ; Durmast oak- woods 6. In every known locality the plant occurs in open woods or as a residual of past ones. During the dry series of summers (1893- 1910) the plant failed and departed, as did Drosera anglica, Erio- phorum angustifolium, and many other species. — E. A. Woodeuefe- Peacock. Having spent a week among the hills north of Liskeard, E. Cornwall, and another in theYelverton and Tavistock district of Dart- moor, S. Devon, it may be interesting to add to ray note published in 22G THE .TouExvL OF p.or.vyT July that in bothtliose hilly districts this plant seems chiefly confined to the moss}^ crevices of stone walls and dry hedge-banks by road-sides on the granite and slate. Above Pensilva it reaches 800 ft. at least. Only twice did I observe it on heaths or commons (other than on the characteristic dividing walls of both districts) ; and though of rather frequent occurrence, it is, as ever^^where, very thinly distributed, and there are rarely more than one or two plants at a place. That point was most noticeable. One plant was growing among a small quantity of Sphagnum at the edge of a diverted watercourse on the moor by Dousland, Yelverton. These ol)servations tend to substantiate my belief that the distribution of Hypericum humifusmn has been much affected b}" the agency of man. — H. S. Thompson. TERATOLoaT IN Papater orientale. Noticing on June llth one flower, out of many, in a large clump of the above-named Poppy to be of a peculiar erect and funnel-shaped- appearance, 1 examined it more closely, and found it was indeed " corolliflorous," the petal showing no sign of seam or point of conjunction of any kind, being of perfect circular form, nor did there seem any sign of the basal " claws." Colour, the usual brilliant scarlet. So far as is discernible, the capsule seemed normal. I should be glad to know w^hether such an abnormality is of frequent occurrence. I have never myself observed anything like it previously. Measurement of petal 4| inches long. — J. Cosmo Meltill. [The abnormality is referred to by AVorsdell {Principles of Plant Teratology, ii. 250; t. 51. fig. 10) as "one of the best known and most remarkable instances of sympetaly " ; Penzig however {PJian- zen Teratologie) does not record it. — Ed. Journ. Bot.] MiMUSOPS PARTIFOLIA R. Br. In the recent number of his " Contributions to the Queensland Flora " (Botany Bulletin Queens- land Dept. of Agriculture, xxi.) Mr. C. T. White points out that the plate and description assigned to M. Kauki in the Illustratiojis to the Botany of Cook's Voyage, " vol. 2, p. 59, pi. ]94 " should be referred to the species named above. The correction had already been made in the index to the volume, which Mr. "White has overlooked. His citation of *' vol. 2 " is likely to mislead, as the work consists of only one volume, although it originally appeared in parts. Diospyros longipes Hiern in Journ. Bot. 1914, 338, is referred by Mr. White (/. c.) to this species. — James Britten. REVIEWS. Botany of the Living Plant. By F. O. Bower, F.K.S., etc. 580 pp. : Macmillan & Co. 8vo. 25s. net. Professor Bower's new volume appears most opportunely at a time when the veneration of the more modern school of British botanists for everything German has received a fatal set back ; and few things are more desirable than a definite presentation of the BOTA>i OF TirE LITIXG PLAXT 227 subject in an entirely English dress. To the rising generation, the works of continental writers will never acquire the hall-mark of super-scientific value with which they have been regarded ; and as the Oxford University Press has apparently exhausted its supply of inferior translations, and the Cambridge Press has not yet found a satisfactory method of subsidizing really good work, Messrs. Mac- millan are to be congratulated on filKng the gap with an eminently readable and abundantly-illustrated volume of convenient size, though at an inconveniently high war-price. Seven shillings and sixpence should be about the limit for this class of work ; the first edition of the Bonn text-book, of very much the same size and scope was issued at six-and-sixj)ence. The volmne comprises a series of 32 chapters, arranged as a sequence of lectures or pleasantly-written essays on plant-organization, beginning with the more familiar types of higher Land-Flora and extending in a cursory manner to some algal and fungus types, as generally introduced in an elementary course at all British Universities. The book in fact covers the general ground of all such class-work, and may be utilized for all elementary university examinations ; though on the whole it is perhaps more particularly dedicated to the general scientific reader who wants a rapid review of a wide field, while the price will place it beyond the range of most students. After the experience of the Bonn text-book, in which four writers collaborate, it is a bold venture for one man to attempt an adequate presentation of the subject as a whole ; but as this commonly falls to the lot of teachers in British institutions, it is interesting to see how Prof. Bower has covered the ground. Emphasis as to the " Living Plant " is apparently intended to indicate that formal anatomy is cut down to the minimum ; physio- logy possibly even beyond the margin of safety; while increasing attention is paid to the ** biological " problems of the plant, as expressed in chapters on the " Water-Eelation," " Mechanical Con- struction," " Vegetative Propagation," " Fruit and Seed-Dispersal " ; the Angiosperm being covered in some 300 pages, few openings being without an illustration. As special features may be noted, a final chapter on ** Sex and Heredity," while an Appendix in smaller type solves the difficulty of bringing in some sort of traditional account of Floral Families without trespassing on the main trend of the text. The main chapters are written with the breezy directness one associates with the work of Prof. Bowser, though one misses the dog- matic enthusiasm which led to the demonstration of JLycopodium Selago as the most archaic of Land-forms ; and one's greatest admira- ration is exercised for the ingenious manner in which the writer so often evades the point rather than insist on any particular attitude or conclusion. Hence though the volume fulfils its mission of adding one more view of the subject to many existing works of much the same scope, it does not add any particularly new outlook on plant- life in general. One still finds little suggestion of answ^ers to such fundamental questions as where a land-plant really came from, or why plants are made of cells at all. or why they reproduce in such an extraordinarily complex manner? While covering the 2'2S THE JOURNAL OP I?OTAXV conventional range ot the subject very well, the writer does not break any new ground ; and things have not apparently' changed very much in the last thirty years of this teaching. While acknowledging tlve care and multitudinous interests de- manded in the ])roduction of such a volume, a botanical journal may be permitted to pick a few holes. As a detailed exposition of scien- titic botany the book does not compare in any wRy with the familiar Strasburger, though it ma}^ prove more attractive to the general reader. To the serious student the greatest demerit is the practically entire want of references to wider literature. The skimpiest account of an}^ phenomenon may suffice in a text-book, provided one can be given reasonable references ; such cases may be illustrated by the doubtful remarks on the vitality of seeds (p. 298) ; the speculations on the origin of Wheat (p. 54S) which omit any reference to Triiicum Mermoms ; the case of Cytisus Adami without mention of Chimaera-forms, and the account of Mendelian segregation stopping short of the " sixteen square " which alone renders the subject of any practical value : even the account of Protococcus on the bark of a tree, on the very first j^age, may come as a shock to many algolo- gists ; Huxley's Profococcus had at least the merit of being fiagellated. As examples of skating over thin ice may be compared the account of " falling starch " (p. 126), and the recognition of a Fucus plant as a " diploid sporoph^^te " (p. 387). The continual use of " germ" for embrj^o has an irritating effect, when the word is used in many senses from Bacteria to Germ-plasma, and much the same applies to the use of '* e^g " for oosphere ; " Transpiration-Stream " is no imjjrovement on the old Transpiration- Current, while " cohesion " and *' adhesion " in floral organization seem somewhat archaic. Much of the text will bear steady revision, and many of the conclusions are loosely wn-itten : — " The w^hole vegetative system may be regarded as a physiological scaffold, w^hile the mechanism of propagation is the substantive building which is erected by means of it" (p. 210), whatever it may be intended to imply, omits all reference to the fact that it is reproduction as devoted to the improvement of the race which is the main issue ; similarly, "The Central Question of Evolu- tion comes finally to the origin of the Heritable Mutations " begs the question as to why anything to begin with should be at all accurately heritable. The publication of the volume also raises a wider issue ; it un- doubtedly epitomizes the class of work taught, not only at Glasgow by Professor Bower but also in many other botanical centres in this country, as the routine of " Elementary Botany " ; and the point arises as to what extent this class of modern Avork, largely plausible and made *' interesting," really does afford a foundation for accurate reasoning in terms of experiment, or deduction of genemlizations from accurately observed facts, compai-able with the general presen- tation of elementarj^ chemistry or physics, with which botanj^ as the scientific analysis of the problems of plant-life, is expected to hold its own. Is " Elementary Botany " to deteriorate in *' Nature Study," or is it to be an exact science in which facts are stated, and BOTAM' OF THE LIVING PLAXT 229 definite conclusions drawn, while the word " probably " is not so insistent at every point of difficulty. Students only too readily pick ■up the habit of vagueness and indefiniteness where precision is the more needed as the subject becomes the more complex. Professor Bowers volume may be thus welcomed as an admirable first draft of a useful text-book, and one may look for emendations in many details in later editions. A Dictionary of the Flowering Plants and Ferns. By J. C. Willis, M.A., Sc.D. Fom-th edition revised and rewritten. Cr. 8vo, cloth, pp. xii, 712, liv. Price £1 net. Cambridge University Press. This work made its first apjDearance in 1897, when it formed the second part of the Manual and Dictionary which was noticed by Dr. Kendle in this Journal for that year (p. 109). The reviewer, while praising the Dictionary, criticized the Manual portion some- what severely, and not without effect, as the notice of the second edition showed (Journ. Bot. 1904, 158). A third edition appeared in 1908 and w^as reprinted six years later: we now have it "completelv revised and as far as possible brought up to date." The most note- worthy featm-e of this new edition is " the incorporation of all the parts into one general dictionary and the omission of Part I. of previous editions." The result is a volmne which it would be impossible to commend too warmly. By an ingenious method of compression fully described in the introduction, an astonishing amount of information is conveyed. " All the genera of Bentham, Hooker, Engler, Prantl, and Linnaeus are now^ included, as w^ell as all given in the Index Kewensis and Supplements (except many synonyms) together with a large number published since the last Suj^plement, and which {sic) by the kindness of the Director at Kew, the compiler has been able to obtain from the MS. lists kej^t at Kew." Each name is follow^ed by that of its author ; then comes that of the family to which it belono-s, with a statement of the number of species contained therein and its geographical distribution ; " the histological peculiarities of the most important genera are dealt with pretty fully : in deahng with the pollination-methods of fiow^ers a selection of important genera, illus- trating the various methods, has been made ; so too with epiphytes, xerophytes, the morphology of parts, and so on. Economic botany has been more fully treated, only comparatively few genera being omitted." English and colonial names are well represented, as are also botanical terms, with explanations. There are also general articles of considerable length, of which an index is given : the very full and practical instructions on collecting occupy more than four pages— the pamphlet on the subject issued by the Department of Botany should have been included in the literature indicated, than w^hich it is more readily accessible. In an appendix is a key to the families of floAvering plants, based on Engler's classification. In typography and arrange- ment the volume leaves nothing to be desired : it is a book which should find a place in every botanical library, however small. We note that Dr. Willis invites additions and corrections, and 230 THE .TOL'JtNAL OF BOTAINY even provides a " slip " on which these may be entered. The pages of this Journal will provide him with some : thus Miers's genus Micrcea^ entered as " Inc. sed.," was identified as long ago as 1880 (p. 20) with Ruellia dulcis Cav. ; Decadla Lour. " inc. sed." is in the same Journal for 1914 (p. 146) shown by Mr. Moore {op. cit. 148) to be identical with Si/mplocos,SiS is also Dicalyx oi the same author, which Dr. Willis omits ; we miss Mr. Moore's Capitajiopsis {op. cit. 1916, 249) ; his identification of Fhocea Seem. {op. cit. 1918, 204) perhaps came too late for inclusion : but enough has been said to suggest a more careful search than appears to have been made. The Living Cycads. By Charles Joseph Chamberlain, xiv-f 172 pp., small 12mo cl., price $1.50. University of Chicago Press. Mr. C. J. Chamberlain has been engaged in the study of Cycads for over fifteen years, and his paper on the reproduction of Dioon (1906) will be regarded as a classic. The present handy little volume contains a general account of the living types of this remarkable group, and is preliminary to a more detailed monograph. The text comprises a useful summary of the more important factors of somatic and reproductive organization of the leading types, in the simplest terms possible ; and in the theoretical discussion evolutionary dogma is not pressed beyond its legitimate bounds. The numerous clear illustrations aid in affording a very definite idea of the botanical interest and value of the living survivors of a once mighty race. Perhaps the part that will be found of greatest interest to British readers will be the account of the plants as found growing in their natural surroundings in the West Indies, Mexico, South Africa, and Australia. For such information, at first hand, the author holds a unique authority. It is also a somewhat curious reflection that the types least known in essential details are those of our own colonies — as the great Macrozamia of Queensland, in process of extirpation, Bowenia and Encephalartos. In a book intended to be semi-popular, exception may be possibly taken to one point — the prominence afforded to sexual terms as " female plant," ** female " sporophyll, eggs and sperms. One might perhaps put up with " ova," but there are certainly no " eggs " in plants, and '* fruiting " individual is quite as effective, and much more accurate, than " female " as apphed to a tree. There is nothing in the way of sex-ditt'erentiation in a plant which may not be covered quite concisely and intelligently by " micro-" and " mega- " (whether in reference to *♦ spore" or "gamete-" mechanism); and where all the customary terms are employed, it would be a matter of congratulation to find a botanist capable of choosing definite and accurate expressions, and scrapping all others. ^ A.H.C. B00K-2S0TES, ^"£WS, ETC. 231 BOOK-NOTES, NEWS, etc. At the meeting of the Linnean Society on June 19, Mr. T. A. Dymes read a paper entitled *' Notes on the Life-history of the Yellow Elag (Iris Pseudacorus Linn.), with special reference to the seeds and seedlings during their first year," of which the following is an abstract: — The xerophytic adaptations and contractile roots of the plant are a protection from some of the dangers of the physical world. Its acridity and astringency protect it from being readily eaten, but the larvae of some insects feed upon it, those of a sawfly do considerable damage ; a few molluscs resort to it for food. It appears that wild- fowl eat the seeds and the very young seedlings ; it is also attacked by a parasitic fungus. Its height and strong growth protect it from practically all its associates. The plant hibernates and the normal minimum for the seeds is about seven months, the maximum being not less than twenty. It flowers in its fourth year ; the capsules begin to dehisce in September. There are two kinds of seed, flat and round, and the difference between them has some significance both in dispersal and in germination. Uninjured seeds float for two years or more. The most important of the agents are diving wild-fowl and the least the wind ; running water plays a very considerable part. The flat seeds are adapted to long-distance dispersal by wild-fowl and to being blown short distances by the wind. The round seeds, with the exception of those afloat on running water, serve to fill up the death gaps at home. There are two phases of germination : — (1) Internal plumular growth followed by (2) the extension of the radicle, the latter requiring the higher temperature. Seeds that have sunk automatically possess an internal water supply and germinate more freely than the floaters. The essentials are continuous moisture coupled with a high temperature. Floaters, seeds at the bottom of shallow water, and those in saturated mud, succeed best : under the most favourable conditions a full 40 per cent, germinate in their first year. In nature the general average is probably 20 per cent. The round seeds appear to germinate in the first year more slowly and to yield a lower average than the flat ones. For seeds in their second year the general average in nature seems to be about the same as for those in their first, 20 per cent., but a good deal more evidence is required. Burial of the seeds is effected by dead leaves and debris, and they are also trodden into soft mud by water-birds. The chief difficulty of the seedling from an unburied seed is to secure anchorage. Frost and air-bubbles lift or uproot the young seedlings. The floaters, which when borne afloat can be distinguished from the mud seedlings by the root sj'stem, are exposed to great dangers ; when together or in debris the}' erect themselves, but unless they drift on to mud or into the shallows either before or after erection they are doomed to death. The height to which seedlings attain during their first year varies from two inches for the flat-floater to thirteen for those in mud from first-year seeds and 19| inches from seeds in their second year. The seedlings perish in inconceivably great multitudes, and probably the vast majority of the floaters are a dead loss to the species. 232 THE JOUR>"AL OF BOTA>'Y At the same meeting Mr. S. L. Moore followed with "A Contri- hution to the Flora of Australia," which contains notices of rare and descriptions of new Australian plants preserved in the British Museum. Robert Brown's Trihulus Systrix and T. occidentalis are shown to have been misunderstood by Bentham and succeeding writers, Bentham's T. Jft/atrLv heing really T. oc cide?i talis, v,'heresis T. Hystrix. unknown except in the type specimen, has much larger fruit with long subulate appendages quite unlike the short conical ones of occideiitalis. Two recent West Australian collections, one by Dr. Stoward, the other by Mr. Marvon, have yielded many novelties, the most interesting being a second species of the Goodeniaceous genus Symjyhyohasis. This genus is peculiar in having an inferior calyx, but a corolla united to the ovary all the way up, together with epigynous stamens. A third 2)art of the memoir relates to plants collected in various parts of the island-continent during the nineteenth century. Among the col- lectors of these special mention was made of Allan Cunningham, Rev. T. S. Lea, George Maxwell, and lastly of John Gilbert, among whose plants have been identified specimens of the recently described Psammomoya clioretroides Diels. & Loesn., remarkable among Celas- traceiB for its leafless habit. Gilbert explored in Queensland and West Australia for Gould, the ornithologist, but also did good botanical collecting ; he was killed by natives in 1845 near the Gulf of Carpentaria. One new genus, Leptospermopsis, is proposed, differing remarkably from Leptospermum, which it much resembles, in the androecium. Science Progress for July contains a long *• article " by Mr. T. G. Hill on "The Water-Economy of Maritime Plants,"" dealing especially with the absorption and transpiration of water by halo- philous plants, particularly by Salicor?iia and Siiceda. Dr. Winifred Brenchley has an " essay " — the reason for the distinction between articles and essays is not obvious — on " The Uses of Weeds and Wild Plants," in which a great deal of information is brought together : the writer's acquaintance with recent British botanical literature does not seem to be extensive, as the authors chietl}^ referred to are Hogg and Johnson (1863), C. P. Johnson (1861-2), Anne Pratt, Wood- ville (1790-92), and Wilson (1847). Under "Recent Advances in Science," Dr. E. J. Salisbury summarizes papers published in various departments of Botany — the paragraphing might be improved — with the exception of Plant Physiology, which is undertaken by Mr. Ingvar Jorgensen. The singularly useless page-headings, to which M'e have already called attention, are continued, so we must assume they have some justification not obvious to the ordinary reader. The Journal of Genetics for June contains two botanical papers : one, by E. J. Collins, on " Sex Segregation in the Brj^ophyta," based upon the ]wpers of El. and Em. Marchal, but with nmch additional evidence, and a plate : the other on " Double P'lowers and Sex- Linkage in Bryonia,'''' by Mr. Bateson and Ida Sutton, containing a series of observations and exi)eriments on M. Davisii, of which a coloured jjlate is given. 233 BKUNFELS AND FUCIIS. By a. H. Chubch. The projected issue of a second volume of the Camh ridge British Flo7'a, with a prospect of the continuation of this much- needed work, spaced over many years to come, as also the criticism it invites — that somehow it is not the sort of thing the ordinary British Botanist would put forward as his ideal of what a future work on indigenous vegetation should be (especially in the matter of figures, or even price), — suggests a comparison Avith the production of similar works in the past. Though the ordinary botanist may not be con- versant A\T.th the complications of a modern University Press, he can comprehend the methods of meeting similar jH'oblems on the part of ancient craftsmen, who worked more or less single-handed ; and it is legitimate to compare the results. The original standard for all subsequent volumes of illustrations of plants was set up by the genius of one man, Leonard Fuchs *(1501- 1566), a leading physician and professor of his time, a wealthy man of considerable influence and with great insight into the scientific needs of his day. His volume ' De Histoeia Stiepium,' published at Basle (1542), is generally recognized as the starting-point of floristic work, in addition to its significance as a compendium of the 'Virtues of Herbs.' This volume comprises over 500 (519) folio drawings, with asso- ciated text, of plants growing in South Germany, drawn directly from nature, where possible of life size, on a page 14 in. by 9 f. Portraits of the men responsible for the figures, Heinrich Fiillmaurer and Albrecht Meyer, are shown on the last page, with the methods by which they Avorked :J:, and also, as a special chef cVceucre of his own Avood-cutting, that of the engraver Yitus Rudolph Speckle. Bearing in mind the fact that Fuchs AA-as at the time in his forty-second 3'ear, that Speckle as ' the best engraver in Strasburg ' apparently cut all the blocks, and that the material had to be collected and dravA^n mainly in the summer months, it is evident that at the rate of a block a Aveek, the work aa^ouM have taken ten years to complete §, and that Fuchs must have conceived the idea Avhen a comparatively * C/.

This conception of Fuchs, the first in botanical history, of de- liberately devising a covirse of work and study on an indigenous flora, in addition to the medical standpoint of illustrating the herbs of the national pharmacopa?ia, was a great and original one, and it was carried out on broad and generous lines. He selected a page, folio size, as adapted to the dimensions of the general range of herbs which can be handled readily ; the work was beautifully printed on good paper, which in an undamaged copy is as clean and good to-day as it was in 1542. T^'pography and make-up were perfect, and far superior to much of the work of subsequent herbals a hundred years later *. His illustrators were evidently well-trained and capable draughtsmen, brought up in the best school of the art and technique of the day, while Speckle the engraver, as shown in the cutting of his own portrait was an equally superior craftsman in his own line. The special interest of the work of these men lies in the fact that they were not botanists, nor even naturalists in any sense as we sliould say to-day ; there is no evidence that they had any taste for Botany or any sesthetic perception of the beauty of flowers : they drew the plants given them, and drew w^hat they saw in very correct proportions and detail, as good draughtsmen, and greatly improAed as the work proceeded — it is as remarkable to note how^ much detail they reallv did see, as to note what they left out. The technique of the work, using a line 250 /i wide, scarcely admitted of the representation of any really fine detail, as hairs, stamens, or parts of small florets less than 1-2 mm. diameter. But as draughtsmen, retaining a sense of propoi-tion and balance, as in the form and arrangement of foliage- leaves, they had ultimately little to learn ; while as designers, they iehowed a sound instinct for placing a type on paper and displaying it, even to the extent of more than a slight conventionalization in the design. They were more at home with fine large hei'baceous plants suitable for decorative treatment, than in the strict natural study of the minutiie of an organism, and even the name and number of the plant are conspicuousl}' well placed f. Perhaps the most striking feature of these plates is the recog- nition of the fact that these earh^ draughtsmen did not pick and choose bits for illustration ; they dre\v the wdiole plant, roots and all, as a scientific and dignified presentation of the organism as a wdiole. To give a man, for example, a cabbage, root and all, a quill pen or a fine brush, and to tell him to make a finished artistic presentation of it, in line only, on a sheet of foolscap, is no mean test of craftmanship. The solution of such a problem by the draughtsmen of Fuchs (F. 416 : Ar. 59 j may Avell be studied by any who propose to illustrate a British Flora %• * Cf. in this country Gerard, ed. 2 (1633), Parkinson (1640). t Ar. 149, 147, 126 : F.

BKLNFELS AND FL'CHS 235 In these days when cheap methods of photographic reproduction have destroyed the future of wood-engraving, and cheap illustration implies the plainest line-work with no "shading' to conceal deficiencies of workmanship, rapidity of work and (output being considered more desirable than careful drawing, which takes time as well as skill — the tendency of botanical illusti-ation will be to return to pen-work of the kind done by these old masters : line- work as represented by copj^ei'- plate engraving of the last century being also extinct, though un- doubtedly in its capacity for delicate detail the ideal method for plant-representation *. For this reason the work of such draughtsmen as those of Fuchs, who set the standard for the sixteenth century herbalists of the Low Countries, from which all subsequent herbals deteriorated t for a hundred years (Parkinson, 1640), deserve to be more thoroughly studied by botanical draughtsmen of the present da}'. These general remarks serve to draw attention to the probability that Fuchs did not originate the w^hole of this conception entirely de novo, but that there must have been some earlier work on which to build. Every botanist has to learn his science from a preceding generation ; the very efficiency of Fuchs' work, '* the culminating point of plant-drawing as an art " :j:, implies a something behind it, of which it may be the glorification, but on similar lines. This work is seen in the more unpretentious volume of Otto Brunfels (1530-31), which stands out as the first recognized work of scientific botany of the new era §. Brunfels' work suffers from many deficiencies to our eyes, it is true ; so does that of Fuchs : these do not require to be emphasized ; the point is to distinguish its great advance beyond anything previously attempted or thought of ; and to value it as giving the clue to the work of Fuchs which tends to overshadow it. From the little that is known of Brunfels, it may be gathered that he was not in inordinately good circumstances ; he had been educated from a plain youth in a monastery, and he followed the ]3rofession of a schoolmaster at Strasburg, and ultimately that of a doctor in private practice. His book a23peared in 1530, when he was apparently 66 years old, and thus beyond any youthful enthusiasm ; while he died in 1531, not long after its partial completion (1531). The * Sibthorp, Flora Grseca (1806): Sowerby, English Botavy (1770): Curtis, Flora Londinensis (1777) : Baxter (1834) : Sargent, Silva of North America (18&2). t Fuchs' noble volume de luxe was copied in many countries*, and rapidly passed through translations and cheaper editions ; the figures being first reduced to 44 by 2-k in., the standard block affected by the Antwerp Herbals; and even to 2| by l| in. (1550). Many of these illustrations lasted long in ' waistcoat- pocket herbals ' (Du Pinet, 1561 ; Linocier, 1620). Such figures attempting to represent entire plants in quite a few lines are interesting examples of reduction, and are on a fair way to imitate Sumerian pictograms. The only work which really set out to improve on Fuchs is Besler's Hortus Eystetfevsis (1613) with copper-plate figures on a page 21 in. by 16, large enough to take a full-size Sun- flower head. The book requires a wheel-barrow to take it about, but the figiu-es are merely large and do not express increased detail. : Ar.^175. § Sachs. Hist. Botany, p. 14 : Arber, p. 47. s 2 236 THE JOURNAL OF BOTA>'^T engraver of his blocks is known (Ar. p. 50), but the di-aughtsman is not otherwise recorded *. From internal evidence it may be sufficiently assumed that Brunfels drew the figures himself ; he had little money to pay for them being done, and in the absence of any other claimant he should certainly be credited with them. No one but the man w^ho had spent hours over them could have so insisted on the value and trath of his " viva? eicones " f- The figures are relatively few, inserted without special plan, and consist of individual stnclies, clearly done without premeditation, and not o-iven for every plant, as they might have been if commissioned. The first volume contains 83 ; the second, published in the following vear, 49 : it is thus probable that the latter gives the time of engraving, at about one a week ; and there seems every possibility that the figures were drawn by Brunfels in his younger days (a man does not do such fine work when over sixty), and that the existence of these figures determined him to publish the accompanying text, which is a compilation of no great value. It is interesting to note even at this early date the list of 47 authorities consulted ; many of these are little known as botanists, the work being of a medical nature rather than scientifically botanical, except for the figures. The inclusion of these was evidently a special idea of Brunfels on his own initiative. He thus appears as the earliest Nature Student, of the type idealized by Euskin, with a capacity for observing small points far beyond his time, and in fact beyond many who came after him. Even Fuchs' men attached no importance to the smaller details of a flower, and rarely drew them ; they became great at * stem and leaf,' but floral foi-m and mechanism was beyond them, as also such minor points as bracts, stipules and adventitious roots. The first part (1530) shows Brunfels rather in the hands of the publisher, who inserted the title-page of the period (including a doubtful Venus, more definite Silenus, Dioscorides, and a melancholy Apollo Avith a 'cello) ; a flamboyant red and black escutcheon spoils a whole page, and large Biblical initials are used (the P of Plantago records Lot's daughters and the Pillar of Salt). In the second part (1531) such meciiieval excrescences are removed ; the title-page is sensible as a plain design, one ornamental border is retained for contents-page, and the initials are taken from a good fount. The make-up of the volume thus passes from one epoch to another. His page-block is 9^ in. by 5| (or 10 by 6 ; again a good ratio) ; but only half the figures are ])rmted on a whole page ; the others are incorporated with the text. There is no attempt to design the page ; a big plant may be doubled up to make it go in. (Ai*. 48) ; small ones are put in corners ; but are well arranged (vol. ii.) with the text balancing the design. {Alche- milla, ii. 53.) As plant-studies, these figures are still admirable in every respect. It is diflicult to realize that the man who did them knew no botan}^ * Arber naively suggests that the engi-aver drew them — so used are we to the inferiority of the artistic profession ; but there is no reason why they should have been so dcjne. any more than modern work is left to the printer or process- engraver. t " Sumnia cum diligentia et artificio effigatac/' : and truly so. BRUXFELS AXD FUCHS 237 as we should say nowadays, and did not know the names of tlie parts or their functions ; but merely copied them faithfully. He even copied the broken leaves and drooping damaged shoots *. He is also great on roots, fibrous, adventitious and borne at the nodes, or pulled up and stripped clean. Fuchs' men inclined to treat roots as deco- rative fibrous growths (F. 52, 88, 192, 317, 4-33, 623, 715). Brunfels had not evolved the idea of putting flowers and fruits on the same inflorescence, so common with his successors. The figures of both Brunfels and Fuchs are often criticised, and, what is just as bad, admired, by people who have not the slightest idea of what they were intended for, or how they were done. These men did not set out to make pretty pictures or artistic sketches. In the absence of modern botanical superiority all parts were equally valuable. The whole plant was considered as an organism, roots and all : they were not biassed in favour of roots because tliese were used in medicine ; roots do not form a predominant feature of the Materia Medica, any more than in Horticulture and Agriculture. Pharma- ceutical material is restricted to the parts which may be more readily handled and stored without damage t. To dig up a plant and wash it clean, with as little damage as possible to radical leaves, etc., and then draw it, presents an aspect of the type very different from the same form growing in the ground. Anyone can try this for a Crocus or Daisy, Primrose or a White Dead Nettle (Br. i. 152) J, without attempting the more difficult case of a sacculent Comfrey or draggled Water-lily. It is our own ignorance of the plant as a whole, and a preference for pretty floral shoots, which makes the rooted plants of the herbalists appear strange. It may be noted that neither Brunfels nor Fuchs, even at their best, went out of their way to find foliage- shoots with insect-eaten leaves as increasing the artistic effect. It is not to be supposed that all these figures are equally good ; if they were they Avould be better known ; but the marvel grows that they were apparently the first studies of the small and trivial plants of North Europe to be put on record in a scientific work §. Among the finest examples of Brunfels' work, which thus appear * Arber (p. 172) alludes to this as a failing, in the evolution of the 'ideal' figure ; but this was before the days of the Cambridge British Flora : cf. Hunny- bun, 74, 84,91, 105. f Dried stems, leaves, bark, roots, rhizomes: British Pharmacopoeia, 10 "/g roots, 10 "'o rhizomes. J One can see in Brunfels' figure the clinging of the wet root-fibres. § Nor need it be supposed that people in the sixteenth century could not draw. A charming study by Albert Diirer, 1526, (Ar. 168) of a Columbine and some grass, shows the perfect delicacy of possible presentation ; the flower is poor, and if cut as a line-block would be no better than that of Fuchs (102) : but making sketches, and figures for reproduction that can be cut in recognizable form by the engraver, are two very different propositions. The engraver and the printer are the sttimbling-blocks, as admirably exemplified by Arber's valuable work, in which Herharius and the Ortus Saaitatis seem quite at home. The same may be noted for example on comparing original drawings by Doyle with the early cuts in Punch : even Du Maurier has left on record his ' weekly pang.' The emulation of fifteenth century printing is not restricted to the Cambridge Press : translations of PfefPer, Jost, and especially Knuth, by the Oxford Press, are similarly defaced by crude block printing. 238 THE JOURNAL OF BOTANY as samples and specimens of technique, ratlier than a definite set course of illustration, may be mentioned the Anemo7ie Puhatilla (Br. i. 217), a beautiful study both in drawing and engraving of a softly hairy type (much spoilt in Arber, 171) ; a study of a Colts- foot shoot, pulled up and flagging (Br. i. 41) is good enough for a modern drawing-copy, and will be referred to later ; the first drawing of a fern, Scolopendrium (Br. ii. 40: Ar, pirated reduction, 174). Examples showing the method of work, with flagging leaves or damaged basal portions, may be found in Twaj^-blade (i. 282), Wood- Anemone (ii. 80), Burdock (ii. 61), Saxifrage (i. 185)— the care taken in doing the figures shows the exact condition of the specimen. Further details may be noted in : — the Herb-Kobert (ii. 37), from a dry situation : a small cut, yet showing flowers and fruits ; the former with 5 petals and 5 stamens ; even the sepal-fringes are indicated ; tlie Wild Strawberry (ii. 35) shows runners and an offset, flowers and fruit ; the fruits pendulous and the dichasial construction properly drawn ; the Tway-blade (i. 182) is correct in the scale-leaves on the axis, the details of the flowers and buds, and the drooj^ing of the wilting inflorescence ; the Lamiums (i. 152) have quite well-drawn corollas with hoods; Salvia (ii. 26) shows the extended bilobed stigma ; in Helleborus (i. 30 ; Ar. 49) the prefloration of the sepals is correct, and nectaries are indicated as well as stamens— the fine scale- leaf at the base is particularly well figured ; the Yellow Flag (Br. ii. 47) is arranged to show two tunnels of the flower, with stigmatic flaps, the third being foreshortened, in the neatest way possible, though not clear at first sight. Knowing what the details of the flowers really are, one of course expects to see them in a botanical figure nowadays : but such details are not found in other herbalists ; and modern floras may be conspicuously poor in representing detail which is there, but not seen. The sets of Plantains (i. 23-25), Malvas (ii. 70-72), and Orchids (i. 103-106) are particularly good : one of the last indicates the spiral twist of the ovary : the Bee Orchis and the SpirantJies are quite characteristic — the small flowers on the spiral of tlie latter show up with a lens. Most remarkable of all pei'haps are the figures of Niipliar (i. 36) and Nymplicea (i. 37), drawn the full size of the page (10 in. b}" 6^); these are the boldest types of the work, printed to face each other ; the NijinplicBa blossom is arranged to show the 4 crossed sepals, stamens, stigmatic disk, and apical papilla ; the dead submerged blossom and the sizes of the coming buds, as also the rhizome with its phyllotaxis scars and a lateral vegetative bud (Ar. 141, details lost in reproduo tion) *. The Nupliar again shows the pattern on the stigmatic disk, the leaf-scars of the rhizome with their peculiar adventitious roots, as also the broken submerged leaves, some completely worn away. The idea of getting a complete specimen of such a plant at all at this date expresses the initial difliculty of the problem, and is a lesson to * According to Arber (p. 172) this figure exactly expresses a Water Lily plant ' buoyed up by the water.' This misses the point of Brimfels' method. Really it is an entire plant dug up, washed and arranged on a table, and dra^vn as it was with the leaves spaced out flat. A water-lily does not grow like this at all, the leaves are arranged in a quincuncial rosette ; the flower is erected. BRUXFELS AND FUCHS 239 modern illustrators who collect bits of plants or one flower, and are ignorant of the whole. These two figures are of the greater interest in that being so completelj satisfactory they were copied by Fuchs' men, and very badly copied at that. The appearance of adaptations of these figures in Fuchs (oBo, 53(5) is sufficient evidence that the former had Brunfels' work as a guide : while their mode of dealing witl\ them sufficiently displays their weakness as copyists and scientific observers (proof of copying is always given by the reversal of the figure in cutting and printing a second time : cf. Ar. 14?1). The adaptation of Nymphcea is badly done ; the central detail of the flower is ignored, and made a decorative muddle ; the aspect of the plant is wholly changed by the thickening of the petioles, and by losing the sense of the long straight stalk of the flower: the detail of the rhizome is left out. On the other hand, JSfiiphar is deliberately faked till it is almost unrecognizable ; the curves are lost, the petioles thickened and all the damaged submerged leaves repaired by ti-ansf erring those of Hy niphce a -^'Atiei'n : a second flower, a failure, is added to complete the picture, though Nuphar shoots do not produce two blossoms at the same time. Uncomprehended details of the rhizome and roots are equally scamped : it is obviously" more difficult to repeat a mis- understood abstract drawing than to copy concrete examples of the living plant *. The fine effect of these two bold figures, filling 02)posite sides of the same opening, shows at once the origin of the idea of Fuchs in taking a still larger page, and so fixing the size of the future herbal. While in Brunfels the figures are mainly "illustrations" to illuminate and decorate the text, which does not explain them — only half of them being printed as whole-page figures, and the others incorporated with the text, often so neatly that the text balances the design, — Fuchs definitely inaugurated the " page-plate " as we term it ; and each figure stands as an individual design without reference to an3"thing else f. That subsequent herbalists (Ma tthiolus, Lobelius, Dodontfius) all descended again to text-figures, must not obscure the fact that Fuchs first clearly saw the advantage of the best drawings of Brunfels, and gave increased significance to his illustrations as distinct from the text. The fact that the production of these plates must have taken some years after the death of Bi-unfels, and that it is evident that the work of Brunfels was in the hands of Fuchs' men, suggests more definitely that they used this work as a basis on which to learn their botanical methods ; and that the curious difference in merit of some of their designs indicates their gradual improvement as * It is interesting to trace the further decadence of these figures in the successive reduction of Fuchs' blocks in translations ; cf. French Trans. (1549) cciii,, 4i by 2j in. and (1550) Lyon, p. 374, to 2^ by \\. In the smaller texts (Du Pinet, Leyden, 1561, p. 404 ; Linocier, Paris, 1620, p. 412) they are replaced by still inferior copies of a picture-block from Matthiolus (Ar. 144). The 4^-in. copies may be seen in Turner (1551), ii. p. 65 ; but being poor they are replaced in other herbals (Gerard, etc.). t Only a couple of small figures of Mosses are printed in Fuchs as text- illustrations — Polytrichum with gracefully- curved setae (p. 629). 24:0 THE JOL'UNAL OF BOTANY time went on *. In tliis way the evolution of the botanical plate at its best may be traced in the pages of Fuchs ; this explains the remarkable inequality of the work ; a fine drawing being often closely associated in the more or less alphabetical arrangement of the text with an inferior ' mediaeval ' one. It is, for example, difficult to believe that the same men drew 747 and 751, 463 and 467, 883 and 886, 286 and 289, if we did not know by personal experience how a few years will improve a system of technique. The drawings of Fuchs may be classed as good, indifferent, and very bad ; the bad ones of some of the commonest and often least effective forms being their tirst rather crude attempts at floral work ; while in their best efforts, after some years of training, the possibilities of their craft- manship become apparent. Nothing brings out the value of Brunfels' figures more clearly than their later imitations. Brunfels' plants were mostly small and quite common weeds, in which the greater care was necessary to preserve a resemblance to an easily recognized growth-form ; and these would be just the t^^pes non-botanical designers would find most difficult to tackle. [Who can mistake the liower Brunfels figures as one he didn't know the name of (ii. 80 ' Herha si/lvestris ignoti nomhiis' ?) — and what was the point of putting it in the book if he hadn't drawn it himself ?] Thus Brunfels' Viola shoots (i. 135) are delightfully natural ; Fuchs (311) is ver}' feeble in comparison. The Pansy of Brunfels (i. 69) is a good figure of the Corn-field form, with vivid details; Fuchs' (803) is hardly recognizable as a Pansy at all. Brunfels' Hart's Tongue is the earliest line-study of a Fern (a reduced pirated copy Ar. 174). but that of Fuchs is childish beside it. Brunfels' Yellow Flag (ii. 47) is very good for a large plant with a complex flower, and the flower is correctly drawn ; that of Fuchs is distinctly poor. Similarlv, it is only necessary to compare the Plantains (B. i. 5, F. 39, Ar. 149 j ; Malvas (B. ii. 72, F. 508) ; ^cilla hifolia (B. i. 184, F. 838) ; Ficaria (B.i. 215, F. 867) ; Belpluninm (B. i. 83, F. 27); Aiiaram (B. i. 71, F. 9, Ar., spoilt, 169 : and Camhrichfe Flora, i. 113) to see that Brunfels is well ahead in scientific perception as well as in draughtmanship. Others are equally interesting as showing, even with the help of fresh specimens, the effort of Fuchs' men to copy Brunfels rather than to copy the plant. Cf. the Alchemilla of Brunfels. ii, 53, F. 612 ; Saxifrage (B. i. 185, F. 747); Groundsel (B. i. 120. F. 612); Sanicle (B. i. 80, F. 671). The Ivy (B. ii. 3 and 4) is obviously the inspiration of Fuchs, 421 ; yet how much superior is the shaping of the umbel seen from below, in Brunfels. The IleUehorus (B. i. 30J is a beautiful study, that of Fuchs (274) is very poor, but it shows it is a flagging specimen, and so one of the older figures, before it occurred to them that the plants looked better if kept in water. The * The same thing ia very strikingly noticed in Baxter's amateur production : the first plates (1833 and undated) are extremely poor, only after 2-3 years was tlie possibility of the simple method worked out: there is thus some hope for the further improvement of the Candiridge British Flora. BRUXFELS AND FUCHS O-tl Strawberry of Brimfels (ii. 35 ) is again botanically admirable within its limitations, with regard to the diehasial inflorescence, runners, and flowers ; but in Fuchs (853) it is ^particularly badly done ; fruits are added to the flowering inflorescence, there are blossoms of two sizes on the same axis ; the leaf-arrangement and shoot-construction, recognizably correct in Brunfels, are hopelessh^ bungled, and the biggest fruit is erected. The case of the Coltsfoot is of special interest, because it is again illuminative with regard to the original mode of work. The block of Brunfels (i, ttl) is a distinctly fine study of a pulled up summer leafy shoot, with broken rhizome and wilting lower leaves. The same shoot cooked appears in Fuchs (F. 140, Ar. 147), reversed, the drooping leaves touched up, and two inflorescence axes added. Everybody knows how straight these axes stand, and the drooping of the older capitula. The graceful curves, and the insertion of the new shoots out of sight behind the petioles, shows the ingenuitv of the fake, as well as its definite disregard of the facts of the case. The intention, however, was undoubtedly good, that of giving dilferent aspects of the plant in a composite figure ; and the same applies in a cruder manner to the Strawberry ; but Brunfels was tKe more scientific. These presumably earlier figures based on Brunfels, and ahvavs much inferior, present an earlier aspect of the work. It was succeeded by a long period of indifferent studies representing the slow improve- ment of the draughtsmen, and probabl}' also of the engraver of this particular class of work. The cutting of the eailier figures is as poor as the draughtmanship, witli a thick coarse line (Asarum, F. 10) ; and perliaps half the plates may be included within this epoch. But once beyond this stage, and beginning to acquire facilitv in handling leaf -form and spatial arrangement, improvement is verv marked ; if the illustrations had not got beyond the preceding stage the}'- would have never attracted any attention beyond those of Bock, Matthiolus, or Tabernaemontanus. The new departures undoubtedly express the result of several ^^ears" experience on the part of men, originally formal draughtsmen and designers, who had now been put through a course of natm-e-study, direct from the plant, in the manner of Brunfels ; and though still ignorant of scientific " botany," the results were wholly beyond expectation. Many of the older"^ blocks are quite fine designs, and might be done by artists of no botanical knowledge ; like many nowadays, in the ordinary course of conventional art-instruction. Thus the Vine (F. 84) may be a good drawing, but it is not a botanist's idea of Vitis ; nor is the beautiful conventional figure of the Oak Tree (F. 229), which miglit be used for a book cover : cf. also the Hop (164), Plum (403), Pumpkin (701). The first advance is noted in the improvement of the aspect of the leaves in shape, insertion, angular divergence, and perspective — quite a large number of plants afford fine studies of foliage ; the decussate types begin to be well done ; in the case of the Teasel, a bijugate system is well-expressed (224), Ar. 176 ; spiral forms take some doing, and there may be at first a tendency to leave out the leaves on the off-side of the stem : but some of the finest plates show a realiv remarkable sense of 3-dimensional space-form : cf. 5Q, 57, 72, 129, 242 THE .TOUBNAL OF BOTAyT 142, 190. 218, 289, 299, 381 Isatis, 468 Good King Henry, 469, 674, 751, 792, 829, 828. Other figures are especially characterized by the breadth and dignity of th« design as a whole ; and these naturally attract the most attention, even if the botanical details be a little vague : but such types are the joy of the book, and give it its value as a work of art. Cf. Paris 87, Clematis 77, (xentian, with one blossom centred, 200, Lactiica 299, Melon 868 (design better than the botany). Cabbage 416, Pea 627 (with a centred pod opened, good enough for a work on Mendel), Fetasites 644, Ar. 126; Radish 660, Comfrey 695, Echallium 705, Millet 771, Mullein 848, Cowslip 850 (for once beyond Brunfels' i. 96, washed-out plant). Finally, there remains the new departure of the more definitely scientific diagram, in which a composite structure is built up to express facts drawn from the life of the plant at diiferent seasons — whether of flower and fruit, or summer and winter habit ; the whole being fitted into a conventional growth-form, planned to fill the plate-space. The idea lacks the perfect scientific accuracy of Brunfels, and is obviously open to abuse, may be readily misunderstood by the ignorant, and may serv^e as an excuse for malrepresentation of the facts ; but it is a distinctly legitiLuate method to attempt, and appeals to the designers, though the verdict of succeeding generations has been against it. These figures are clearly due to the direction of Fuchs himself ; they give the botanical value of the work, and the method grows from small beginnings — -^). has a fruiting specimen added, and an interior of the bottle- cavity, with remarkably correct detail of ovaries and stigmas, etc. The figures are kept separate ; a more crude effort in Dracuiiculus (284) fits the fruits and the spathe on the same stem ; and must be so far regarded as a definite failure. The same applies to the Columbine (102) and Paeonia (202) ; though the practice lasted for a long time, and may be noted in the Pa?ony of Besler (1618), Hort. Eyst. p. vi, 10. Two figures again are given for Crocus vernus (441), one with a second dimerous flower, and another of a later stage with the leaves shooting, the dead flowers, and fine contractile roots pushing — an admirable set of botanical facts. Colchicum (356) is also shown separately in flowers and fruit. The method is clearly more satisfactory as adapted to conven- tionalized fruit-trees, in which different branches are set apart for the different effects and the whole grouped as a tree-form : it is question- able whether the shreds and patches of the Cambridge British Flora are really any better as affording an adequate presentation to the ignorant of the growth-form of a tree-type. Many examples are par- ticularly neat. Gf. especially the Gooseberry, 187 ; Blackthorn, 404 — a beautiful study, with bare branch, flowering branch, and fruiting branch, — only requiring colour to make it vividly accui'ute. The Hazel (898), with a catkin-bearing twig, Cherry (415), also with three types of branch-system : Juglans (379) with catkins added, and BRrXFELS AXD FUCKS 243 nuts; Peach (601), Rihes (663), very well-done for inconspicuous flowers, as also Erviom (571) with procession of flowers and fruits, and the Isatis (415) with flowering and fruiting branches. It is difficult to beheve that the men who produced jthese figures began with the feeble Herb Robert (206), ConvaUaria (240), Corn Pansy (803), Scolopendrium (294), or faked the Nupliar, Yellow Iris, and Coltsfoot as plants particularly adapted for bold decorative treat- ment, yet made such beautiful studies from most insignificant flower- types as Lettuce (229), Isatis (331), and Grood King Henry (463). On the other hand, with all their acquired skill in plant-presenta- tion, Fuchs' men do not show any corresponding advance in the observation and reproduction of the more minute botanical details which we look for nowadays, and were present in the original specimens ; Brunf els' figures with a wealth of accurate detail, expressed ' summa cum diligentia,' rather reveal the true germ of scientific enquiry. The draughtsmen of Fuchs are to be credited with their steadfast labour and great output, on a rising scale of excellence, along the lines on which they had been originally trained. Again, the engraving of Wieditz for Brunfels is far superior to anything in the earlier figures of Fuchs ; one has an uncomfortable feeling that Speckle would have made a mess of Brunfels' Pulsatilla (i. 217) or the Asarum (i. 71, P. 10). There is nothing in all Fuchs to compare with the flower of the Pulsatilla or that of Hellehorus (B. i. 30). Brunfels' figures are apparently drawn with a pen, giving fine and deep strokes, with turns and movements intentiona% broken, as well as in fine clean lines {cf. ii. 52, 53) : the earlier figures of Fuchs have a poor thick line ; only in some of the early more decorative designs (Cabbage, 416 ; Oak, 229 ; Melon, 368) is a heavy line used locally with great effect. The special method evolved iii later work tends to the use of a uniformh^ clear smooth line, in the manner admired b}' modern process-engravers, and a limiting expression of this type of work in the Comfrey (F. 695) may be at last fairly placed by the side of Weiditz's 75 of Brunfels (A. 48). The significance of these records is sufficiently obvious ; the work of Brunfels and Fuchs covers the whole province of the fundamentals of botanical illusti-ation. To the construction of type-figures and plate-filling with the dignity and restraint attained by the remarkable draughtsmen of Fuchs — and the art of leaving out details too fine to be repeated, as giving a breadth of design to the whole — requires to be added the more faithful scientific observation of Brunfels, and his recognition of the importance of pourtraying the distinct individuality of every plant-organism, hi its natural mode of growth, and the consideration of the plant as a whole. The addition of special botanical details, as accurate drawings, or neat combinations in a diagram of established convention, is again exemplified by Fuchs ; while the clearness of line-reproduction exjDressed in the work of Speckle puts to shame modern methods of line process-work, and on a scale quite comparable with that of modern work. The admiration and respect of posterity is earned only by those who utilize to the utm(jst the resoui-ces of their age : and nothing is worth doing which is not of the verv best. If the British Flora of the future, passing 2-44 THE .rOLM^XAL OF BOl'ANY' beyond the horizon of hand-coloured copper-plates, as in Curtis and Sowerby of a hundred years ago, is to come back to cheap process line-blocks, these should be entrusted to those who not only have received an adequate art-training of their generation, and really know something of floral botany, but who have an instinctive appreciation of the bewildering manifestations of plant-life, and can utilize an artistic training without falling into absurd mannerisms or slip-shod ways. It is a pity that copies of Brunfels and Fuchs are not more readily available for the study of those whose ideas of Herbals are foundied on the poor borrowed illustrations of Grerard and Parkinson.

By Horace W. Moncktox, V.P.L.S. 1 HATE for a good many years made a practice of noting the plants which I saw growing on various geological formations, and I have attempted to make complete lists of the Flora of certain selected geological areas. The district of the Bagshot Sands on and around Bagsiiot Heath affords an unusually suitable area for this purpose. It is fairly extensive, being 24 miles from east to west and 11 miles from north to south ; its boundary is tolerably regular and there are T 2 252 THE JOUllNAL OF B0TA5fY neither inliers nor outliers of other geological formations. It is tme that a considerable portion of the surface is formed of various gravels but the gravel is much the same from the point of view of plant-life as the Bagshot Sand itself ; the surface is, in fact, mainly sand and o-ravel with subordinate beds of clay or sandy clay, and there is an absence of lime in the area. In 1916 I had a few copies of my list of plants from this district printed for the use of those interested, and a note on the Flora was read to the Linnean Society and published in their Proceedings for 1915-16, p. 5 (see Journ. Bot. 1916, 94). I have since added some- what to my list and, taking the 16th edition of the London Catalogue, I have now marked 705 species, 43 varieties, and 8 hybrids as growing on the Bagshot Sand ; 15 other species on Alluvium in the district, and 83 species as recorded, but not, I think, established. This makes a total of 854 entries. As I have said, the Bagshot of this area is mainly a sand formation, and we should expect to find a i*esemblance in its Flora to that of other similar formations in the south of England, and, in 'fact, most of our plants do occur on the Eocene of the south coast as well as on the Lower Greensand and Hastings Beds. The resemblance to the Flora of the Lower Greensand is especially marked, but as that formation contains beds of limestone, such as the Bargate Stone, we find some species on it w^hich are absent from our area. The con- ditions of plant-life are, however, so similar to those in other places that I cannot name any species which is confined to the Bagshot District ; still there are some plants which are distinctly characteristic of our area. Ranunculus Lenormandi F. Schultz is described in Fl. Berks, p. 14, as occurring only on th^ Bagshot Beds in that county, and I have found it at several places on the Middle Bagshot Beds in both the Berks and Surrey part of our District. It occurs on the Lower Bagshot in a damp field by a small brook about a mile and a half south of Wokingham and Mr. C. E. Britton tells me that it is found on Esher Common, also Lower Bagshot. In Hampshire I found it on the Yalle}" Gravel of the Black water at Yately ; this gravel is . underlain by Bagshot Beds and is in the Bagshot District. The Kev. E. F. Linton describes the species from the Dorset Bagshot Beds (Fl. Bournemouth, p. 27), and it has been recorded from the * Hastings Beds and Lower Greensand. In Brewer's Flora of Surrey^ it is marked for the London Clay, pp. 4, 319, but I believe that to be an exceptional occurrence. Hypericum JElodes L. is found in abundance in many of the lakes and ponds of the district : I may mention Wellington College and Chobham Common as examples for the Middle Bagshot and Ockham •Common for the Lower Bagshot (see also Fl. Berks, pp. xli, 116; Fl. Surrey, p. 47 ; Fl. Hamps. p. 70). It is common on the Bagshot Beds of Dorset, and has been recorded from the Lower Greensand and Hastings Beds, but is wanting on many geological formations. Hieracium is more abundant on the Bagshot Sand than on the adjoining fonnations, and the species have not yet been fully worked out. This applies more especially to the group Vulgata. My THE FLOEA OF THE BAGSHOT DISTEICT 253 specimens have been kindly looked over by the Eevs. E. F. Linton and E. S. Marshall. Some from Wellington College are placed near H. grandidens Dahlst. or H. serrati^rons var. lepistoides Johan. ; one from the same place and one from Finchampstead Eidges are near H. surrejanum F. J. Hanb. ; one from St. Sebastian near Wokingham is named H. pinnatijidum var. vivarium Lonnr. ; two from Wellington College are described as H. scanicum or a form near it ; one fi-om AVellington College and one from Broadmoor are assigned to H. sciapliiliiin Uechtr. ; and one from Finchampstead to H. sciapliilum var. fransiens. Mr. Linton considere that a number of my specimens from Wellington College belong to an midescribed species, for which he proposes the name H. euryphyllum. There is less difficulty as to the species in the other groups (see Fl. Berks, pp. 312-315), but I may mention that I have found H. tridentafum var. setigerum Ley at Wellington College and var. acrifolium Dahlst. at Gracious Pond Farm, Woking, and on Wey- bridge Common, Surrey. From the Valley Gravel of the Bagshot District I have H. rigidum Hartm. from Sandhurst, Berks, and Walton Common, Surrey, and H. umhellafum var. coronopifoliiuii Fr. from Sandhm-st. Vaccinium My rt ill us L. is a plant of the Bagshot Sand, Lower Greensand, Hastings Beds, and other sandy formations. In the Bagshot District there are many patches of this plant in what were woods of JPinns sylvestn's, both on the Bagshot Sand and the Plateau Gravel. Many of these woods have now been cut down, and I am curious to see how the Vaccinium will thrive. Gentiana Pneumonanthe L. is given by Brewer (Fl. Surrey, pp. 150, 332) as occurring only on the Bagshot Sand in that county, and the two localities given in FL Berks (p. 342) are probably on the same Formation. It is frequent on the corresponding series in Dorset (Fl. Bournemouth, p. 150). In Townsend's Fl. Hamps. (p. 258) it is recorded from Hook Common ; this is near Odiham, and is an interesting example of the transgression of the Bagshot Sand plant on to Plateau Gravel, which rests on London Clay. It is about half a mile S.E. of the nearest Bagshot outlier at Newnham and a mile and a half from the main mass of the Bagshot Sand. Specimens from this locality Avere given me by the late Miss Cole a few years ago. Euphrasia is characteristic of the Bagshot Sand ; Mr. Dunnis Lumb has been good enough to look over m}^ specimens and. deter- mines them as follows : — E. Rosfkoviana, Hayne is the most frequent species ; I have exam])les from Wellington College, the East Berks golf links, Birchen Inhams farm near Wokingham, and from East- hampstead Moor, all in Berks. I also found it on the Valley Gravel at Yately, Hants. E. hrevipila Burnat & Gremli occurred at Wellington College some ^^ears ago. E. nemorosa var. ciliaia is frequent at the same place, and E. gracilis Fr. I have from Wellington College and from the Valley Gravel at Cox Hill Green near Chobham, Surrey ; Mr. C. E. Britton tells me that it occurs on Ockham Common. Myrica Gale L. is abundant in many parts of the Bagshot District, and Mr. Hautneville Cope showed me a valley near Bramshill 254 THE ,TOURNAL OF BOTANY where it was growing in luxuriance. It is frequent on the Bagshot Beds of Dorset and is recorded from Sussex, apparently on Lower Greensand and Hastings Beds (Arnold, Fl. Sussex, p. 101). Illecehrum verticillatum L. is one of the curiosities of the district. Its occurrence is described by Mr. Druce (Fl. Berks, 416), and it has for a long time appeared in two places ; one has now been enclosed in a fowl-yard and the plant will probably vanish thence, but last year it had spread a good deal in the other locality. Certain ])iants common on the chalk have transgressed on to the Bao-shot Sand ; thus I have found Polyfjala vulgaris L. at Welling- ton College ; Campanula glomerata L. has flowered at the same place near Crowthorne for several ^^ears in succession, and I believe originated through the ground being treated with a chalk dressing. Legousia hyhrida Delarbr. grows on Birchen Inhams Farm, AVoking- ham, and in Dorset it is recorded from the Bagshot Beds of Creech clay-pits (Fl. Bournemouth, p. 142). In the case of some of the plants which occur everywhere interest attaches to some varieties, thus Taraxacum officinale var, erythro- spermum Andrz. is frequent on the football grounds at Wellington College, and occurs at other places in the district. It is recorded from the con-esponding formation of Dorset. Ar noser is piisilla Gaertn., a colonist, is recorded from several places on the Bagshot Sand in Fl. Surrey (p. 124) and the only locality given in Fl. Berks (p. 308) is in the Bagshot district. In Fl. Hamps. it is given from the Bagshot Beds of both North and South Hants. I found it in a field near Brimshot, Surrey, in 1915 and have seen it for several successive 3'ears near Yately, Hants. It is recorded from the Lower Greensand and the Blackheath Pebble Beds. Claytonia perfoliata Don, a native of North America, was recorded as established on Bagshot Sand at Yately, Hants, by the late Rev. C. W. Penny (Journ. Bot. 1873, 206) ; it "is still there in more than one place, but it is around Horsell Birch in Surrey that it flourishes in the greatest abundance on the Bagshot Sand, and near Chobham I have seen it on Valley Gravel. It has been recorded from both Eocene and Purbeck Beds in South Hants and Dorset (Fl. Bournem. p. 55). Anchusa officinalis L., a native of Central and Southern Europe, was found by Mr. Druce near Finchampstead in 1891 (Fl. Berks, p. 349) ; I saw it, possibly at the same place, in 1918. Though well within the Bagshot district it was not on the Bagshot Sand, but on an overlying patch of Plateau Gi*avel. Juncus tennis Willd., also a native of the Continent, was found by myself near Wellington College in 1915 ; it seems to be spreading, for it was growing in more than one place last season. Sedges are abundant in the Bagshot District. Mr. Druce gives a few characteristic species (Fl. Berks, p. xh) and 29 species are recorded from the Bagshot Sand in the Flora of Surrey. I make the number of species 38, and four others are recorded, but I think only occur on the Alluvium. I myself have found 22 species, most of them on the Middle Bagshot, but I have seen a good many on both Cpper and Lower Bagshot and tliey often extend on to the gravels. THE FLORA OF THE BAGSHOT DISTRICT 255 Rhynchosjpora alha Valil is found on Chobham Common and near Wellington College, and other localities will be found in the County Floras. It is recorded as common in the Bournemouth District (Headon Beds, Bagshot Series, Gravel) and as occurring on Lower Ureensand and Hastings Beds. Schyusfluitaiis L. is found near Wellington College and at other places in our district, and is recorded from Bagshot Beds, Headon Beds, and Grravel of the south coast and also from Blackheath Beds, Lower G-reensand, and Hastings Beds. Carex canesceiis is recorded from the Surrey, Berks, and Hants parts of the Bagshot district, and I have specimens from Sandhurst. It also is found on the Bagshot Sei'ies of the Bournemouth District and on the Lower Grreensand at Beigate. I have specimens of a pretty Sedge from Chobham Common and boggy ground near Broad- moor very like C.Jlava var. Icpidocarpa Syme (E. Bot. t. 1673), which is made a variety of C.Jlavu in the London Catalogue, Berks (p. 550) gives C.Jlava var. minor from Bagshot Sand localities; this is made a variet}'' of C. Oederi Betz. in the London Catalogue. In Fl. Hamps. (p. 475) two species are given for the Bagshot District — C.Jlava var. minor Towns, and C. Oederi Retz. Whatever the correct nomenclature may be, I think that I may safely count two species for the district. I may mention that King John's Bog, Odiham, where ^oo({Jlava gemiina was found (Fl. Hamps.) is off the Bagshot Sand, and is on wet Valley Gravel or Alluvium underlain by London Clay. C.Jlava var. minor is recorded from the Bagshot Series of the south coast, the Lower Greensand, Hastings Beds, and also from Andover (Chalk), Keston (Blackheath Beds), below Cray- ford (Valley Deposits), and Dungeness (Gravel). Carex binervis Sm. is abundant on our commons, more especially on Middle Bagshot Beds. It is recorded from the corresponding Series of Bournemouth, from the Headon Beds, Lower Greensand, Hastings Beds, and from the Blackheath Beds of Keston, &c. Carex Pseudo-Ggperus L. is given amongst the plants of the Bagshot Sand in Fl. Berks (p. xli). I have specimens from Ockham Common and the Basingstoke Canal, but though it grows freely enough where it occurs, I should call it a plant of the Alluvium and Valley Gravel which has strayed into our district. It is described as rather rare in Hants, but is more common in marshy places in Kent. SPHAGNACEiE. Sphagnum is found in some abundance in a great number of streams and bogs in the district ; the patches are not as a rule large, but there is a considerable variety of species. Some of them are given in Mr. Horrell's paper on the European SphagnacecB, published in this Journal for 1900, with the localities Brookwood, Pirbright, North Camp, and probably Aldershot, which are situated on Bagshot Sand. I myself have chiefly collected from the Berkshire part of the district ; my specimens have been kindly determined by Mr. W. R. Sherrin, and I have added in the following list a few species from Chobham Common, Surrey, communicated by him. ^.'G tup: .lOUltXAL OF liOTA^V There are many beds of Sphagnum by the streams Avhieh rise on the Plateau Gravel of Easthampsteacl Plain and flow .across the moors in Easthampstead parish, which I consequently describe as Easthampstead Moor. The Sphagnum is particularly well developed near the place where these streams pass from the Upper to the Middle Bagshot Beds. In a few places Sphagnum is found on the Lower Bagshot Beds and occasionall}^ on the Valley Gravel, and even on the Plateau Gravel. The following localities given in my list are in Berkshire : — Broadmoor in Crowthorne ; Easthampstead Park and Moor in Easthampstead ; Finchampstead Wood in Finchampstead ; Grebe Pond in Wokingham; Heath Pool in Finchampstead; Long Moor in Barkham ; Queensmere in Wokingham ; Spout Pond in Finchampstead ; Swinle}^ Park in Sunninghill ; Wellington College in Crowthorne.

Miller and I spent an hour or two near Holford, v.c. 5 S. Somerset, which is a very rich neighbourhood botanically, and produces a good many scarce Huhi. In the lower part of one of the combes we noticed a large -flowered Mullein, which at once struck me as being very like V. phlomoides L., a species which I gathered thirty-nine years ago near Marburg, Hessen-Nassau, growing under very similar conditions. I have since traced it for nearly half a mile ; it occurs sparingly both in the open and in bushy places, sometimes extending, among bracken, for twenty yards or more up the wooded hillside, facing east. A casual observer might easily pass it by as fine V. Thapsiis, from which it mainly dift'ers by the larger, flatter corollas, of a brighter vellow, the lono-er 258 THE JOURXAL OP BOTANY pair of naked filaments, the large, vivid orange anthers, longly de- current on their filaments, and the stigmas being decurrent, less decidedl}^ capitate. On consulting text-books, our plants were found to agree in foliage with thapsiforme rather than with phlomoides ; and an examination of the European sets in the National Herbarium proved this to be the case. In Mr. S. T. Dunn's Alien Flora, p. 147, he says : — *' Occasionally noticed as a garden escape in England." Whether it has really so occurred I do not know, though I have much doubt. In the present station it has ever}^ appearance of a true native, growing in similar situations to those which produce V. Thnpsus, and often as solitary, considerably isolated individuals. A friend at Bridgwater, who has grown sundry exotic Mulleins, assures me that he did not introduce it; and, personally, I am convinced that it is indigenous. The average height is two to three feet ; but one plant was met with — in stony, exposed soil, with smaller flowers — little more than a foot high, whereas the strongest specimen obsei-vei reached a height of about six feet (Mr. Edgar Lovett recently saw V. Thapsus eight feet high ; and I have seen it, naturalised, at least as tall, if not taller, on the Canadian side, below Niagara Falls). Now arises a question as to its specific rank. Most authorities, such as Bentham, Koch, Rouy, and Nyman, keep it up, rightly regarding V. cuspidatum Schiud. as only a variety. In DC. Fro- dromus (x. 226) Bentham aptly remarks : — *' Folia V. Thapsi^ flores V. phlomoides.'''' Coste, however, reduces it to a variety of the latter ; and Lloj^d was of the same opinion. Though by no means a " lumper," I am strongly in favour of this view. The big plant referred to above had an exceptionally large, thick inflorescence, with three branches from near the base, and one or two of the middle leaves were only decurrent halfwa}^ down to the leaf below : so it would do just as well for V. phlomoides, sensu stricto. I suggest therefore that we should write it " V. phlomoides L., var. (or subsp.) thapsiforme Coste." Flowers dried separately are seen to be softly adpressed-pubescent externally. In the Student's Handbook (1870 to 1884), under " Excluded Species," Sir J. D. Hooker wrote : — " Verhascum thapsiforme Schrad. Keported by Hudson ; not confirmed." This was careless : Hudson (ed. ii. p. 90, 1778) cited V. thapsoides L., which Linnaeus himself queried as a probable hybrid. V. Thapsvs was not observed in or near the Holford station. Schrader's original description is as follows : — " Verhascum Thapsiforme, foliis decurrentibus crenulatis tomentosis : superioribus acuminatis, racemo spieato denso, corollie rotatae laciniis obovatis rotundatis, antheris duabus oblongis . . . *' Facies Thapsi. Caulis sesquipedalis, bipedalis et quandoque altior, erectus, teretiusculus, simplex . . . Calices Thapsi, Corollae magni- tudine, forma et colore Phlomoidis.'" H. A. Schrader, Monographia Generis Verbasci, p. 21 (1813). TACCTXIUM IXTERMEDTUM 259 VACCINIUM INTERMEDIUM IIutiie. Br W. Balfour Gourlat, M.B., and G. M. Veters, M.R.C.S. This natural hybrid between Vaccinium Myrtilhis and V. Vitis- idcea was discovered in Britain by Robert Garner in Maer Woods, Staffordshire, and was exhibited by him at the meeting of the Linnean Society on March 7, 1872, when " the general opinion elicited hj their examination was that they were a luxuriant state of V. Vitis-icl(Ba, due to situation, rather than a hybrid " (see Journ. Bot. 1872, 122). It was fully described by Mr. N. E. Brown in Journ. Linn. Soc. xxiv. 125 (1887) as V. intermedium Ruthe, from specimens collected by T. G. Bonney in August 1886 on Cannock Chase ; in a postscript to the paper, which is accompanied by an excellent plate, these are identified with Garner's specimens exhilDited at the Linnean Society. Since then little notice seems to have been taken of the plant, but several rather interesting points and questions arise when one examines its habit and distribution. In the first place it is locally very abundant in the Cannock Chase area of Staffordshire — we have found it in a score of distinct and widely-separate locaHties. Slight variations in plants from the different localities and their wide separation suggest different acts of hybridization for each locality. The onl}^ other place in Britain from which it has been recorded is Caithness. This is rather remark- able, for one would think that there must be many other localities where the parent species grow together and hybridization might take place ; none, however, have been recorded, and it seems unlikely that the jjlant occurs and has been overlooked in such areas, as the upland regions of Britain have been carefull}^ botanized. The question arises, Can any circumstance at Cannock Chase be specially favourable for the production or spread of the h^^brid ? The answer to this seems to be : Human interference. In all but three localities in which the plant was found there was indisputable evidence of man's handiwork. Cannock Chase during the last five years, and for many years before to a lesser degree, has been a military ti-aining-area, and many roads, trenches, gun-pits, and drains have been constructed ; and it was in such localities that the hybrid was found. Moreover, where the work of man is recent the patch is small and vice versa, e. g., patches one yard square were found in conjunction with work obviously done since the beginning of the War, whereas one large patch of an acre in extent had its focus in an artificial bank on which birch-trees of considerable size were growing, proving it to be some twenty years old. Each patch spreads vegetatively by creeping rootstock.s. In unmolested areas Bilberry and Cowberry grow intermingled, but in such areas the hybrid is conspicuous by its absence. It would be interesting to know if the Caithness locality gives similar evidence of human interference. It may be noted that V. Myrtillus flowers earlier than V. Vitis- idcea, though some overlapping usually occurs. The hybrid resembles the latter in the cylindrical stem and evergreen and rather coriaceous leaf, but favours the former in having awned anthers and in the shape 200 THE JOURNAL OF BOT.O'Y and colour o£ the ripe berry, which, however, is plum-violet rather than dark blue. The hybrid fruits much less freely than either parent, and its flowers ai-e roughly intermediate in size and shape ; it would be of interest to know which is the male and which the female parent. In the paper mentioned above, Mr. Brown states that the discoverer of the plant sent specimens to Darwin, who suggested that the seeds would show infertility. So far as we are aware, no one has since investigated this point : we have collected and distributed a considerable amount of seed for experimental sowing, and hope to make a definite statement at some future date. SHORT NOTES, Uthicularia. The size of the species of this genus as given in our books is far too small. Syme (Eng. Bot. ed. 3, vii. 126, 1867) gives for U. vulgaris " 6-18 inches long," and for Z7. intermedia *' 6 inches." Messrs. Burrell & Clarke (Trans. Norf. & Nor. Nat. Soc. ix. 266, 1911) give U. vulgaris as occm-ring on East Buston Common " 6 feet long " and on Foulden Common Avith flower-stalks *' 15 inches long." I have Z7. major 24 Inches long gathered by the late George Nicholson at Staines, Middlesex. XT. minor often occurs in Norfolk 9-10 inches and U. intet^media 12-15 inches long. — A. Bennett.

Price 6s. net. The enormously enhanced cost of book-production is only too evident when a leading firm of publishers has to charge six shillings net for little more than 180 small pages — less than 70,000 words — COMMEECIAL FOKESTET IN BllITAIN 261 printed on inferior paper and somewhat roughly bound. As to the matter of this latest essay by Mr. Stebbing we have no fault to find. It strikes us as being- a remarkabl^^ sane, temperate, and opportune statement. The writer first states briefly the direct and indirect utility of forests to a nation — how new industries demanding wood, such as paper-pulp and aeroplanes, have arisen, so that, in spite of all substitutes, wood is at least as indispensable as ever ; and how forests tend to regulate the water-supply, arrest shifting sand, and so preserve the agricultural value of land. He, then, in 63 pages traces the his- tory of Bi-itish Forestry from Koman times to 1914, sketching in a most interesting summarj^ the conversion of primeval forest into agricultural land, the demand for oak for the Nav}^ Evelyn's stimulus to planting and the cessation of this demand with the coming in of teak and steel, and the cheap import of the soft woods from the forests of the Continent and of North America. The nadir of British Forestry Avas reached between 1866, when the duties on imported timber were removed, and 1885, when the first Parliamentar}' Committee on Forestry was appointed. At that period the owners of woodlands " neither knew, nor pretended to know, an}i:hing about forestry" — "the estate agent was usually equally ignorant " ; the woods " were chiefly regarded from their usefulness in affording sport or amenity " : British-grown pit- wood was so badly grown that colliery-owners preferred imported material. Government specifications commonly stipulated for foreign wood, and timber- merchants learnt that they could not obtain any continuous supply of home-grown wood. Mr. Stebbing then narrates with a surprising patience and absence of bitterness the history of seven successive Committees and Commissions, Avhich " resolves itself, if we omit Ireland, into some small encouragement of education, but a total absence of all planting-up of the waste lands of the country." It may fairly be said, moreover, that, until the difficulty of obtaining matches, fire-wood, and paper forced it on public attention, little or no general interest in the matter was evinced. The second half of the book, dealing with our immediate timber- requirements after the devastation caused by the War and our possible future resources, is, of course, of a more immediate practical interest. A concise summary is given of the available timber- supplies in various countries, with the conclusion, now familiar to us from the author's previous publications, that we must look mainly to Russia. In this, perhaps, he somewhat overlooks the inevitable enhancement of the price of timber that will render possible the exj)loitation of the less accessible British Columbian supply as readily, perhaps, as that of any from Siberia. Home afforesta- tion, it is cogently argued, "should, in combination with agricul- ture, greatly ameliorate the sociah conditions of tlie people resident in the areas of . . . the poorer classes of soil . . . should lead to the resettlement on these areas ... of a larger hardy population . . . and . . . result in placing the nation in a position of secuiity in the matter of its timber supplies in the event of war." Incidentally, Mr. Stebbing argues that if we are to have successful coniferous forests in Britain we must get rid of rabbits, bhick-cock and roe-deer ; 262 THE JOURNAL OF BOTANY and his administrative conclusion is that "by far the greater pro- portion of land required for aiforestation should be acquired by either ordinary leasing or leases on a profit-sharing basis— the State only purchasing areas sufficient to enable it to demonstrate in different parts of the country that commercial forestry could be made to pay." G. S. BOULGER. BOOK-NOTES, NEWS, etc. Mr. T. F, Cheeseman sends us a copy of the account of the Vascular Floi*a of Macquarie Island which he has contributed to the ScientiHc Reports (vol. vii. pt. 3) of the Australian Antarctic Expedition of 1911-14. The island, which "lies rather more than 600 miles to the south-west of New Zealand and is approximately 920 miles from Tasmania," was discovered in 1810 by Captain Hassel- borough of the ship ' Perseverance,' which had been despatched from Sydney for the purpose of searching for islands inhabited b}^ fur- seals. "These were found to be extremely numerous ; it is said that one vessel alone, during the first year of its operations, took away more than 35,000 skins " ; as a natural consequence " the species was nearly exterminated : it is now a rare occurrence to see a fur-seal on Macquarie Island." The island, however, was visited for many successive years for the purpose of procuring sea-elephant oil and penguin oil," and the communication which thus existed between New Zealand and the island led to visits from Dr. Scott in 1880 and Mr. A. Hamilton in 1894, both of whom paid attention to its fauna and flora. A subsidiary base in connection with the Australian An- tarctic Expedition was established, and large collections were made in all branches of biological science ; the botany was investigated by Mr. Harold Hamilton, and this paper is mainly based on his collec- tions. Mr. Cheeseman, however, gives a full account of the work of previous collections, the first of which, consisting of eight species, enumerated in the Flora Antarctica, was sent to W. J. Hooker by Charles Eraser about 1810. The number of native species of flower- ing plants enumerated is 30, of which three — Deschampsia penicil- lata T. Kirk, Foa Hamiltoni T. Kirk, and Triodia macquariensis, now first described — are endemic ; three ferns and a lycopod make up the vascular flora — the other cryptogamy will be described in future volumes of the Reports. The memoir abounds in notes, descriptive and other, upon the species and concludes with an exceedingly interesting and valuable chapter on the "affinities, history, and origin of the flora " — it is in fact in ever}^ way a scholarly piece of work. In the index the specific names precede those of the genera — " acaulis Ranunculus" — a somewhat novel arrangement; the genera, how- ever, are also indexed. We have received the first number (July) of The Journal of the Arnold Arboretum, edited by Prof. C. S. Sargent, which is designed to take fche place of Garden and Forest, the last volume of which appeared in 1897. The new Journal, which is to appear quarterly, will contain "notes on trees and shrubs or descriptions of new species and their relationships, letters from correspondents, and notes on the vegetation of countries visited by officers and agents of the BOOK->'OTES, NEWS, ETC. 263 Arboretum." The number before us contains Notes on American Willows of the Pleonandrw Group, by Camillo Schneider ; a Phyto- geographical Sketch of the Ligneous Flora on Korea, by E. H. Wilson ; Notes on North American Trees by the editor, in the course of which reasons are shown for the retention of Popuhis tacamaliacca Mill, in place of P. candicans Ait., and Catesby's specimen in the British Museum Herbarium is accepted as the type of P. lalsami- fera L. ; and a paper on " New Species, Varieties and Combinations for the Herbarium and Collections of the Arnold Arboretum " by Alfred Rehder, which is prefaced by some interesting remarks on nomen- clatm-e, especially as this relates to horticulture. The paper contains a large number of new combinations, based as these always should be, on a careful study both of plants and synonjany ; Ave note that '' Ahies alha Mill. Diet. ed. 8, no. 1 (1768) ""^ for the adoption of which for Piniis Picea L. sufficient reasons seem to be given. We note that Mr. E. H. Wilson, who has returned after an absence of more than two A^ears in Japan, has been appointed Assistant Director of the Arboretum. The Journal of the New York JBofanical Garden for June contains an article on " Brackenridge and his Book on Ferns " by Dr. J. H. Barnhart. Although he died in 1893, William D. Brackexeidge does not aj^pear in the Third Supplement to the Biographical Index, though he had every claim to inclusion, as he was born at Ayr, June 10, 1810, and was in charge of Patrick Neill's grounds at Canonmills, Edinburgh : after this he spent several 3'ears on the Continent, part of the time in Poland and the rest under Friedi'ich Otto at Berlin. He went to America about 1837, and in 1838 was attached as assistant botanist to the U.S. Pacific Exploring Expedition. Dr. Barnhart gives a detailed account of the expedition and of Brackenridge's connection with it. On its return, in 1842, the preparation of the report on the ferns collected was placed in his hands, and, after many dela3^s and difficulties, was issued in 1854-55 as vol. xvi. of the Expedition Series ; owinjsr to destmction by fire, copies of the volumes are rare. In 1855 Brackenridge settled near Baltimore, where he became a nurseryman and landscape architect ; "he was for some years horticultural editor of the American Farmer, but his one book was his only contribution of importance to botanical literature " ; he died at Baltimore on Feb. 3, 1893. He is com- memorated in the genus Brackenridge a A. Gray (Ochnacese). The Kew Bulletin (1919, no. 4, published in June) contains a paper by Mr. W. B. Grove on '* Species placed by Saccardo in the Genus Blwma " ; of these a large number are transferred to other geneiu ; there are numerous illustrntions and some new species are described. Mr. Rolf e has what is evidently a careful historical account of " The True Mahoganies," of which three species are recog- nized— Sivietenia Mahagoni Jacq., S. humilis Zucc. and S. macro- p)hylla King. The number also contains a paper on the cultivation of New Zealand Flax {Phormium tenax) in Co. Kerry, and a note on a collection of about 600 drawings of Indian plants which "appear to have been at one time the property of Claude Martin, who was born at Lyons on Jan. 4, 1731, went to India in 1751, and, as an officer of 264 THE JOUKXAL OF BOTATfT the English East India Company, served in the Carnatic wars " : he died at Lucknow, Sept. 13, 1800. Most of the drawings have been named by William Koxbm-gh, who, in his Flora Iiidica, described some new species from material sent by Martin, whom he com- memorated in Andropogon Martini. The Journal of tJie Linnean Society (Botan}^ : xliv. no. 299 ; July 31), contains "A Kevision of some Critical Species of Echinm,'''' by C. C. Lacaita. Under this heading five papers are brought together : 1. Five Critical Species — E. judceum, sp. n., E. austrule Lam. ; E. Coincyanum, nom, nov., E. pycnanthum Pomel, E. salman- ticum Lag. ; 2. The genus in the herbaria of Tournefort, Jussieu, and Lamarck ; 3. The Echia of Sibthorp's herbarium ; 4. The Linnean Species ; 5. The Echia of Miller's Gardener s Dictionary. Mr. Lacaita has made an exhaustive study of the old material, not only in the herbaria mentioned, but in the Sloane Collections and others in the National Herbarium, and his paper is well described by him "as a quarry from which any monographer of the genus may dig material." The other papers in the number are " Plant-Distribution from the Standpoints of an Idealist," by H. B. Guppy, and " On a Malay Form of Ghlorococcum humicoW (with tw^o plates) by B. Muriel Bristol. The Essex Naturalist (xix. pt. 1 ; April 1918-June 1919) contains an exhaustive account by Mr. Miller Christy of " Samuel Dale (1659 P-1739) and the Dak Family " ; a note by Miss Lister on Haheriaria chlorantlia var. tricalcarata ; a supplementary report on the Lichens of Epping Forest by Robert Paulson and Percy G. Thompson : and a description by W. G. Clarke of three Essex her-' baria, one formed by John Freeman (1784-1864), and two by Joseph Freeman (1813-1907) : the herbaria have been presented by Mr. W. H. Freeman (grandson and son) to the Essex Field Club Museum. The last issue of the Becords of the Botanical Survey of India (vol. vi. no. 8 ; Jan. 1919) contains an interesting paper by Mr. C. C. Calder on "The Species of Occalis now wild in India." These are nine in number — O. Acetosella, O. Griffith ii, O. variabilis v-dLX. rubra, O. Pes-caprce, O. corniculata, O.puhescens, 0. tetraphyllay O. latifolia, and O. corymhosa, of which the third, fourth, sixth, seventh, eighth, and ninth are completely naturalized introductions ; the naturalization of O. Bes-caprce is now reported for the tirst time. Mr. Calder gives interesting details of the distribution of the species, of each of which a plate is given. In The Ohio Journal of Science for April is continued the series of papers dealing with the effect of the great eruption on Mount Katmai in Alaska on plant-life and the remarkable recovery of vege- tation around Kodiak "where the new plant covering consisted almost entirely of old perennials which had survived and come up through the ash." In the present instalment Mr. \l. F. Griggs records the first stages of the process in the valley of Katmai liiver : here one of the most notable survivals was Equisetum arvense, which " was able to penetrate deposits so thick that nothing else could come through." A series of illustrations from photographs add to the interest of the paper. 265 HISTORICAL REVIEW OF THE PH^OPHYCE^E. Br A. H. Church. The following notes have been put together as summarizing the progressive discovery of this remarkable race of Marine Algae in the general history of botany, as also illustrating the gradualh^ increas- ing interest in what must ever remain one of the most central groups of the vegetable kingdom, in that it alone, in the present world, affords a view of the rise and development, in the sea, of a massive race of autotrophic benthic organism, from the phase of the plankton- flagellate to the culminating expression of plant-forms, which in point of size may bear comparison Avith the vegetation of the land. These types, again, are undoubtedly the nearest in general organi- zation to the races of marine algae which left the sea to pass through the vicissitudes of the subaerial transmigration, to emerge as the higher Flora of the Land. In this respect, it is interesting to note the part played by British algologists, at a time when little interest was attached to the vege- tation of the sea ; as also to emphasize the essential importance of continued research on this isolated group of plants, rendered pecu- liarly appropriate to the botanists of this country by the geographical position of the British Isles. The subject falls naturally into several epochs, as following the general progression of Botanical Science. I. Theophrastus to the Herbalists (300 b.c.-1623 a.d.). To the first naturalists of ancient Grreece, the common objects of the sea-shore were just the same as they are now, in the same localities, and Theophrastus (300 b.c.) records the plants he saw, and the ones he had heard about from fishermen and sailors. The word (pvicos (* Phycos ') was originally used to cover all marine plants, including such submerged Angiosperms as Posidonia a.nd Zoster a, the litmus-lichen {Roccella) growing on the rocks of Crete, and employed from time immemorial as a cosmetic, as also examples of Red, Brown, and Green Sea-weeds proper — e.g., a red * Sea-Palm,' the 'Oyster-Green' like a crumpled lettuce ( JJIva), and more particularly the C^^stoseiras (' Sea-Oak ' and the ' Sea-Fir') ard the ' Sea- Vine ' {Sargassum) ; the former as miniature trees with thick trunks and branches, the latter with berries like those of the currant- vine. Also he had heard from sailors that at the Pillars of Hercules (Gibraltar) the ocean-tide brought in sea-weeds of marvellous size, ' about a palm-breadth ' (drifted Laminaria saccJiainna) and the ' sea-leek,' growing as high as a man's waist {L. digit ata forms) i. Dioscorides (a.d. 77) and Plint (a.d. 79) have little more to say than record the popular 1 Theophrastus (circa 300 B.C.), Be Historia Plnntarum, Lib. 4, cap. 7.

Journal of Botant, — Vol. 37. rQcTOUKR, 1019.1 u 266 THE JOURNAL OF BOTANY knowledge of the time ; they were only dealing with the same vege- tation i. B}"- the Komans, in fact, the term Fucus wsui used in its primary sense for the Boccella-lichen, as shown by the numerous derivatives in the sense of dyeing, painting, and rouging; further references to sea- vegetation remained dormant for many centuries, until the Renaissance had brought a veneration for the old Greek texts of Theoplirastus and Dioscorides. The first new references are those of Imperato (Naples, 1599), who in his general 'Natural History' mentions many Mediterranean Sea-weeds, as well as the Fucus marinns {Roccella^, Tamarisk- and Myrica-Wkfd Cystoseiras. Fio-ures are given for the ' Palma Marina ' (Floridean) of Theo- phrastus, 'Abies Marina' (a Oystoseira), and even the ' Fuco giganfeo,'' a mythical figure of an oceanic Laminaria digitata, too good to be lost, from, sailors' tales 2. First among the Botanical Herbalists, Lobelttjs^ (Antwerp, 1576) correctly interpreted Theophrastus : The ' Quercus Marinus ' is figured recognizably as a Cgstoseira (an Ahrofanum maris), and his woodcuts include Sargassums {Lenticula) of the Adriatic and Tyrrhenian Seas ! as well as the Fucus Fliiiianus, identified as Vraick of the sea-coast, and the Lichen (Hocella) of Crete. (The use of the word Fucus for the Boccella-lichen persisted until the time of Ray, 1686.) The first really new step was made by Dodon^us in his Stirpmm Hisforice, published after his death (Antwerp, 1616*). In recording Viva, Fosiclonia, and the Fucus of Theophrastus, he mentions that there were some other species as well, and figures very creditably four forms from the Dutch coast : (1) Fucus vesiculosus, (2) Himan- thalia, (3) Ascophyllum, (4) Halidrys. The first of these is rather ingeniously read into Theophrastus' account of the Sea-Oak (cf. Cystoseira ericoides), and other types are referred to the genus Fucus, since had not Theophrastus said that there were others beyond the Pillars of Hercules ! and from this time Fucus primus (F. vesi- culosus) holds its own as No. I. Fucus, or the ' Quercus marina,' as the type for all sea-weeds ; and the systematist's custom of begin- ning the list of sea- weeds with the Fucaceae may be said to sm'vive until the Sylloge Algarum of De Toni (1895). II. Early Systematists (Bauhin, 1620, to Dillexitjs, 1724). Advance beyond this stage was but slow. A few types of plants were isolated, and rather casually named, as by Caspar Bauhin '' (Basle, 1620) who received plants from the beach at Aberdeen ; and 1 Dioscorides (circa 77 a.d.), Lib. 4, cap. 99.

HISTORICAL HEVIEW OF THE PII.EOPHYCILi: 2{57 a few rough blocks were added; cf. JoHNSo:y's Gemrd (1683 j i, and Pahkinson's Theatrum^ (1640). A more imposing technical display was made \>j Morisox^ the first Professor of Botany at Oxford (in the posthumous vol. iii. 1699), in which copper-plate illustrations are given for the first time, though of varying value, and the text comprises a miscellaneous collection of about 60 plants, including with the sea-weeds Zostera and polyzoans. Eat (1686) ^ repeats much the same miscellaneous collection of plants, but without figures, and remarks of little real scientific value. The number of species of Ficcus grew considerably, the name being extended to all shrubby kinds, as opposed to smaller more mossy forms {Micscus marina). Thus Bauhin in his classical JBinax (1623) collects together references to 20 forms of shrubby Fuci. Parkinson (1640) knew 12 English plants (including JJlva and Padina). Tournefort ^ (1700) gives a list of 76 species. In the thii'd edition of Pay's ^Si/nopsis (1724) Dillenjus includes 57 species as Fucus, and these are arranged in artificial classes as they are (1) Branched, (2) Dichotomous, (3) Bilateral, or the converse ^. Dillenius, Sherardian Professor of Botany at Oxford (1734-1747), also amassed a collection of all the common objects of the sea-shore that looked anything like a i:)lant, including sponges, hydroids, polyzoans, and red and brown algae. He collected every- thing he saw on the beach, just as one might do to-day, including about 20 Phseophycea? out of a total of 60 forms 7. The value of this work can be indicated by saying that the same sort of thing could be done by any intelligent and uninstructed boy, as a holiday task, in a few days at the sea-side. As an example of shore-observations, the text is chiefly remarkable for the common plants left out. This is no reflection on the industry of Dillenius, whose province Avas a survey of the whole of the vegetable kingdom, single-handed, but it serves to indicate the highest scientific hoiizon of the time — at any rate, much had been done since the time of Dodonseus. III. Influe>^ce of the LiNN^AJf SrsTEM (1735-1813). From the very chaotic medley of bad descriptions, Lii^?s-j:its (1753), in the first edition of the Species JPlantarum^, reduced the species of Fucus to 27 * shrubby ' forms ; any other sea-weeds being included as Llva (9) and Conferva (21); e.g., Pylaiella littoralis 1 Gerard's Herhall, enlarged and amended by Thomas Johnson (London, 1633), pp. 1567, 1670. - The Theatre of Plants, John Parkinson (London, 1640), pp. 1281, 1292. ^ Plantarum Historiae Universalis Oxonieyisis, pars tertia, by Jacobus Bobar- tius, Oxford, 1699.

Linnaeus' practical knowledge of even the commoner Atlantic sea-weeds was of the most meagre description, and the mistakes he made are excusable. Thus ' Laminaria digitata ' is left out, and the whole of the Laminarians included under L. saccharina, the latter name being borrowed from an allusion to Aleukia ^. Fucus was again included as the first genus of the group Algce, a sub- division of the Cryptogams {Sysfema Naturce, 1785). It is true that his ' Cryptogams ' also included the tree Ficvs, and the Algae, Lemna ; but these minor slips were soon corrected. The essential point is that the 27 species of the genus Fucus were subdivided into 5 sections, much as suggested by Dillenius : — I. Dichotomi frondescentes, II. Dichotomi caulescentes, • III. Ramosi foliis distinctis, IV. Ramosi fronde unita, Y. Fructificationibus non vesicariis, as 4 groups of Fucoids, and the rest. Characteristic representatives of these groups are : — (1) Fucus serratus^ (2) Himanthaliay (3) Sargassum, (4) Hcdidrys, (5) Laminaria, Fadina, and Chorda. Out of the 27 forms, 4 in group V were Floridese. But the old arrange- ment, retaining the commoner Fucoid plants in the premier position was maintained ; and this sequence becomes the guide to subsequent writers, who added new species to the 5 groups. Thus Hudson (1762) ~ increased English forms to Fucus 45, Ulra 10, Conferva 36 ; Lightfoot^ (1777) describes Fucus 43, ZJlva 12, Conferva 26. Under the stimulus of the Linnsean System, and the cult of the Herbarium, Avith greater care in observation and collection, the addi- tion of forms and descriptions proceeded steadily. Increasing interest is shown in sea-weed collecting, apart from the study of flowering plants, and many excellent tigm-es (Lightfoot) enabled the plants to be readily identified ; the few^ drawings of Yellet (1795) "*, and a good set by Stackhouse (1795) °, introducing the use of colour for the first time, and stimulating enquiry as to the nature of the reproductive organs (Yelley). A review of British Algae (WoOD- WAED and GooDENOUGH, 1797) ^ comprises accounts of 72 species of sea-weed, all classed as Fucus, now becoming a jumble of brown and red forms ; and an attempt at a slightly new arrangement is interest- ing, as affording the general plan subsequently emended and followed by Greville and Harvey. Meanwhile, considerable progress had been made on the continent. The honour of writing the first book on Marine Algfe alone is due to Gmelix (St. Petersburg, 176S), though the illustrations were rather crude ^ ; and a finer volume of coloured plates of 96 sp. was pub- ^ Sibbald, Edinburgh (1684), Scotia illust rat a, -part ii. p. 26. 2 Hudson, FLo7'a Anglica (London, 1762), p. 466 : no figures. ^ Lightfoot, Flora Scotica (London, 1777), vol. ii. p. 902. ^ Velley (Bath, 1795), Coloured fiyures of Marine Plants. •-• Stackhouse (Bath, 1795-1801), Nereis Britaymica.

The latter has no special arrangement, but Gmelin distmguished 7 subgenera (ordo) or 7 orders, as well as TJlva and Trefnell a -forms. The issue of the latter may be said to have stimulated Dawson TuR^s^ER in this country to prepare the 4 great quarto volumes of coloured figures -, which mark the culmination of the epoch of collec- tors and naturahsts pure and simple. All the forms are called Fucus, the figures were chiefly drawn by Hooker, and there is no attempt at any arrangement ; but the text is a. monument of general information, and still indispensable to British naturalists, as also for the figures of many foreign species collected by Banks, Mexzies, and Robert Brow^n, from Austraha, the Cape, and Cali- fornia, which are often the most readily available figures and descrip- tions of still little-known plants. Reference to the older literature shows how much had been done under the influence of the Linnsean Sj^stem between 178o and 1819 ; scientific method had been introduced into the subject, and natura- lists and collectors were stimulated for the first time to increasingly careful and detailed observations. But though attention was paid to such details of spore-arrangement as could be seen with a simple lens of low power, little further advance was possible until better microscopic methods had been invented. The fine hand-colom-ed plates of Dawson Turner and Hooker set a standard for future work of this kind ; but the general attitude of the botanist of the period is perhaps summed up by Martyn (1807), — " Many of them {Ficctis sp.) make very beautiful specimens for the herbarium, and are often seen disposed on paper so as to form a sort of picture " ^\ IV. Influence of the Natural System (1789-1851). Contemporaneous with the work of Turner, new ideas were making their way as a consequence of the increasing acceptance of the Natural System of Classification of Flowering Plants, published by A. L. de Jussieu (Paris, 1789), which was to finally supersede the Linnsean System. Plants being successfully grouped for the first time in Subdivisions and ' Natural Orders ' which attempted to map out the more fundamental ' natural affinities ' of the plants in ques- tion. The application of these ideas to sea-weeds was indicated by Lamouroux (1813), who in a striking essaj^ ^ marked out a new scheme, which not only segregated numerous genera, but arranged them in distinct Natural Orders. The fiii'st feature of primary importance was the separation of the Floridese (II.) from the Fucaceae (I.) and the Dictyotacese (III.) ; while such admirable names as JLaminaria^ Desmarestia, Chorda, Dictyota, Padina, Asperococcus were proposed for the new genera. As minor imper- fections of this first attempt, it may be noted that the Floridean ^ Icones Fiicorum, Espsr, Niimberg- (1797), 2 vols., text & plates. - Fuci, Dawson Turner (London, 1808-1809, 1811, 1819), 4 vols. : coloured plates and descriptions of 2.58 species of Fucus, both British and foreign. ^ Martyn (1807) in Miller's Gardener s Dictionary. ■* Lamouroux (Paris, 1813), " Essai sur les Genres dela famille des Thalassio- phytes non articulees." 270 TITE JOUnXAL OF BOTANY FurcpUaria was placed with the Fucaeete, and Amansia with the Dictvotaoeee, while A.tperococciis was relegated to the Ulvaceae. The four orders of Algae included 25 genera, 24 being new, and 9 named after friends of Laniouroux. The creation of new genera thus initiated proceeded rapidly, and Ltngbye (1819) had 49 genera fathered by Stackhouse, Agardh, as well as b}^ Laniouroux and him- self, arranged in 6 ' orders ' ^ ; though unfortunately ' brown ' and 'red' are still mingled, Delesseria coming next to Fucks, and Viva to Lamhiaria. Of these 49 genera Lyngbye was responsible for 11. Similarly, further advance was shown in Sweden by C. Agaedh (1824). The whole of the AlgjB are now comprised in 6 orders, with a total of 70 genera 2, with singular prevision, in series from the simplest (Diatoms) to the ones most like land-plants {Sargassiim). The main series of Green, Red, and Brown Algse begm to emerge as Ulvaceae (13 gen.), Floridese (16 gen.), and Fucoideae (15 gen.). But the Fucoideae still retain Lichina, Lemanea, and Furcellaina, and the Ulvaceae, Forpliyra ; while an order Confervoideae includes a general mixture of filamentous forms, Ectocarpus, Sphacelaria, Mesogloia, with Protonema^ JSatrachospermu?n, Tkorea, Oscillatoria, Chara, Ceramium, Griffithsia, &c. The larger Algae are thus be- ginning to be sorted out ; but great confusion still exists in those requiring more microscopic observation, and little appears to be known about them beyond giving them a name. A short step to the elegant little volume of Geeyille^ (1830) ■ shows a slight advance. A preliminary'- synopsis of Algae includes 14 orders and 89 genera ; but the older arrangement, commencing with Sargasso m and Avorking down, is followed. Lichina is still put among the Fucoids ; Furcellaria and Polyides are again outside the true ' Florideae ' ; so that there can be little insight into either the structure or details of reproduction of these types, although they are figured in a colour one would have thought unmistakable. A more remarkable omission is the whole of the 'Confervoid' forms, including Ectocarpoid types, Sphacelarias, &c. ; these being still kept separate as in D ill wyn\ 1809), following the Linnaean System*. This class of work culminates in the four volumes of the Fhgco- Joqia Britannica of Haryey (1846-1851). About 360 coloui-ed plates of British Marine Algae alone still constitute the standard work of reference on the subject for these shores, and will not be readily superseded. Though these volumes are restricted to British species, the classification expresses the more natui-al relationships, and all the more obvious errors of the past are put right. Brown Sea- weeds (Melanophyceae) are clearly delimited both from the Rhodo- phyceae and the Chlorophyceae ; the first series Melanoi)liycea? (=MelanospermeiB) alone is subdivided into 6 orders, 35 genera, and 97 species. The system is that of Greville, much emended, and is traced from Sargassum down to Ectocarpus and Myriotrichia ; the text is also similar to that of Greville. 1 Lyng-bye (Hafnia, 1819), Tentamen Hydrophytologix Danicae. • C.

HISTORICAL BEYIEW OF THE PHJ20PHTCEJJ 271 The first half of the Nineteenth Century (1800-1850) may be termed the golden age of the collector and systematist. Enthusiastic amateurs who specialized^ in alga-collecting were numerous, and the cult of the Herbarium was accumulating the material utilized by systematists, and building the framework of the science. Nowaday*s one can hardly spare the time and labour for such practices, with a quiet conscience, since ideals of what is most worthy to be done have been considerably raised, and the horizon broadened ; but at that time such efforts were still the expression of the highest outlook of the science — at any rate, in this country. The names of many who helped to erect this monumental work are enshrined in generic or specific names : — e.g. Kalfs of Penzance (1807-90 : Ralfsia), Clous- ton of Orkney (1800-84 : Laminaria Gloustoni), Landsborough of the Sea-Oak fame (1779-1854 : Land slur (jia). Miss Cutler of Sid- mouth (tl866: Gutleria), Miss Gifford of Minehead (1823 ?-91: Glffordia) : others are commemorated in genera of Florideae, as Mrs. Griffiths of Torquay (1768-1858 : Griffithsia, the accepted doyenne of British lady algologists), Mrs. Gatty (1809-73 : Gattya), Mrs. Gulson (fl. 1855 : Gulsonia), Miss Ball (tl872 : Ballia), Miss Hutchins of Bantry (1785-1815: Hutchinsia, now sunk in Polysiphonia), and PoUexsen of Orkney (1813-99; Pollexfenia). It is also interesting to include Mrs. Wyatt of Torquay (fl. 1833 : Wyattia), who with the assistance of Mrs. Griffiths compiled the AlgcB Damnoniensis (4 vols, exsiccata, 234 specimens) to which Harvey's Manual (1841) was largely indebted i. This algological branch of Botan}'- has been now seen, as it were, to grow up : passing through the stage of 'general information,' characteristic of the more or less educated classes of Greek, Renaissance, or modern times, to the Nature- Study phase of the school-boy and the age of Dillenius, on to the adult naturalist and collector, with refined methods for collecting, naming, and determining species and varieties, but not seeming capable of getting much further. The genemtion which produced the Phycologia Britannica and allied works ^ left few successors ; and this work so far again marks the close of an epoch. Henceforward the study of Algse requires a more special botanical training than Avas possible for the collector and amateur, though the function of these is still by no means exhausted, and there is room for many at the present day. A more complete system was drawn up by the younger Agaedh (1848), inclusive of all known algae 3; the Phseophycese alone extend to 7 families and a total of 70 genera, arranged in series from Ecto- carpus to Sargasstim ; and this arrangement constitutes the basis of modern classifications, to be emended with improved outlook, as expressed by further knowledge of reproductive processes and life- histories.

Though the Phycologia General is of Kuetztng (Leip- zig, 184:3) shows no advance as systematic work, since Kuetzing had peculiar ideas of his own with regard to classification, and a great turn for making new genera out of old ones, which did not convince Schleiden i, it is always interesting to turn to this remarkable pioneer volume, which may be said to introduce the atmosphere of the elementary laboratory practice of the present day into the subject, based on the methods of section-cutting and the use of reagents. The Florideae are termed Keterocarpece, and other algse IsocarpecB ; the latter being curiously divided as Gymnospermous and Angio- spermous : the lower Phaeosporeae are still mixed up, Mesogloia being near Bafrachospermum, and Ectocarpus next to Drapariialdia. But the volume gives special attention to anatomical and physiological considerations, while a large number of careful anatomical drawings and figures of the reproductive organs put the available material in quite a new light. Many of these illustrations have done duty in text-books to recent times 2. Though not perfect to modern ej^es, they are quite different from anything attempted previousl}^ — at a time too when cell-theory was still vague, and even ' protoplasm ' had not been established by Von Mohl. Kuetzing also seems to have been the first to introduce the objectionable practice of print- ing the details of ' brown,' * green,' or ' red ' algje in respectively coloured inks ^. V. Mdderx Botaxy. " In the years immediately before and after 1840, a new life began to stir in all parts of botanical research, in anatomy, physiology and morphology " (Sachs) ^. The important additions to the botanical outlook associated with the names of Schleiden, Yon Mohl, Naegeli, Hofmeister, and many others constitute the stimulus which prepared tlie way for conceptions of phylogen}"" and descent implied by the observations of Darwin and his associates ; and the aggregation of these standpoints has made modern botany a subject altogether beyond the dreams of the older school of naturalists. The application of these views to Sea-weeds again came from the other side of the English Channel, and the reseai'ches of Bobis^et and Thueet on Antherozoids and sexual fertilization in Brown and Bed Algae mark the starting-point of new lines of progress. The actual fertilization of Fuciis was observed by Thuret at Cherbourg (1854), though the significance of the sexual organs had been fairW known since 184-3, and the theory of sexuality was rendered clear in both Brown and Bed Algae •^.

HISTORICAL REVIEW OF THE PHiEOPHYCE.E 273 and Sautageau (Gulf of Gascony), while the establishment of the Marine Station at Naples by Anton Dohrn (1878) has enabled inland continental observers to work under favourable circumstances on the shores of the Mediterranean (Berthold, Reinke, Falkenberg, Oltmanns). The writings of these and many such observers are still the working literature of the subject. The latest official review of the group Phseophycea3 is that of Kjellman i (1891), the most complete systematic text (in Latin) that of De Toni (1895) ^, and the most complete text-book that of Oltmani^s ^ (1904-5). General morphological and structural problems have been most successfully dealt with from a modern standpoint by Keinke^ and Oltmanns ^, while Kuckuck ^ (Helgoland) has set the highest standard of draughtmanship for cells and tissue-details ; Sauvageau '^ (Guethary) has shown what can be done with simple line-work. Good figures of weeds in a natural condition, free from the conven- tions of herbarium material are given by Okamura (Tokyo) ^. The opening years of the present century have seen advance in new directions ; as on the ecological side, — the account of the Algal Flora of the Faeroes by Borgesex ^ constituting a model for floristic work, which has been followed by Cottois^i^ for Clare Island in British seas ; while on a more restricted formation Miss Baker i^ has stated the algal problems of the Salt-marsh. A distinctly new standpoint has been introduced in the discussion of cytological problems of the organization of the nucleus in karyogamy and meiosis ( Strasburger, 1897 ; Farmer and Williams, 1898 ; Williams, 1904). In this department Yamanouchi ^^ has set a standard of technique and comprehensive detailed observation for application to all life- cycles, which may be equalled but scarcely surpassed, as expressing the limit of modern microscopic methods. The footnote references are only intended to afford a guide to the best methods of work in the group at the present time — the first desideratum for British seas being undoubtedly a comprehensive account of the British plants, with figures and full structural and ecological details, to replace the Phycologia Britannica of Harvey. ^ Kjellman (1891), Phfeophyceas, in Engler & Prantl's Pflanzenfamilien. - De Toni (1895), Sylloge Fncoidearnm. ^ Oltmanns (Jena, 1904), Morphologie und Biologie der Algen. ■* Reinke (Kiel), cf.

On August 10th I cycled to Charterhouse-on-Mendlp, partly to explore an interesting seventy-acre plot of rough pasture and heather recently bought by a friend interested in botanj^ and geology. This enclosure is primarily a rabbit-warren, with a remarkable chasm or miniature canyon of curious irregularity, and bedecked Avith ferns, running some 200 yards through the carboniferous limestone on the side nearest the Mendip Sanatorium. As noticed in 1915, when I began mapping the distribution of Carex moniana on the Mendip plateau, this sedge is ver}' abundant in this and neighbouring walled enclosures, and on the roadside between Charterhouse and the head of Cheddar Gorge. In May and June the pale green of its narrow grass-like leaves can be seen from iifar ; but in a tine August the colour is a rich yellow-green, so that it forms a distinct feature in the landscape and can be seen a quarter of a mile off, especially when against a belt of heather. The object of this note is to draw the attention of field-botanists to the colour of the foliage of the sedge, because it ma}^ possibl}" be found not only elsewhere on the Mendip Hills but in other English counties, e. g. Wilts and Dorset, from which I believe it is not yet reported. In Somerset C. montana was unknown until the late E. F. Linton found it, when botanizing in July 1»90 with the late K. P. Murray, on a roadside bank close to Charterhouse Church ( Journ. Bot. xxviii. p. 350). In 190S it was seen by Mr. F. Samson in another place in the neighbourhood ; and in 1916 and 1917 I observed that it was " abundant over scores of acres and appeared in spots sev^eral miles apart" (Report of Watson Bot. Exch. Club for 1917, p. 79). This year, on August 10th, I saw it in several patches much nearer Priddy, nearly three miles from where Mr. Pugsley had seen it by the Roman road west of Charterhouse. Two years ago I noticed it in small quantity on approaching from the tableland the extreme head of Cheddar Gorge. All these localities are at an altitude of from 700 to 800 ft., and roughly within the old mining area. When once known in the field C. montana can easily be detected in July or August hundreds of yards off, when riding on a bicycle, so brilliant is the yellow-green of its foliage. The leaves of Brachy- podium sylvaticum are of a very similar colour when growing in the open moorland or rough pasture, as that grass sometimes does on Mendip and elsewhere, but they are much broader. It was the leaves only (of the sedge) which Mr. Linton first detected in July 1890, but' " careful search led to the discovery of a few withering spikes .... and on one of these a single fruit remained." That ■discovery was of a plant new to Watson's Peninsular Province (no. 1) ; for in his Compendium of the Cyhele Britannica (1870) it was recorded from Provinces 2-5 only, and in " Lat. 51-52 or 53 : Sussex, Gloucester, Monmouth, Hereford, Worcestershire." Its present census number in Lond. Cat. ed. 10 (1908) is eleven, for it has also been found in Devon, Hants, and other counties. CAREX MOXTAXA 275 Those unacquainted with this sedge, who may look for it after the seeds have fallen at Midsummer, may detect it by its bright, narrow, very slender, and pointed leaves, 4-8 inches long, or rarely longer ; and make sure of the species by its thick shaggy branched I'hizome to which the fibrous roots are attached. The basal sheaths of the leaves are often reddish purple, as in C. depawperaia^ a very rare and quite di:fferent species, which holds its ground in one spot a few miles from Charterhouse, N. Somerset. In early spring before the flowers are out and when the young leaves of C. moiitana are quite short, and surrounded by last year's dead ones, botanists should search for the erect flowering spikes, which are black before the anthers appear at the end of April. The stems soon elongate and Anally droop in crraceful curves, so that the flowers are often hidden in the mass of leaves. At the end of April 1917 I saw at Charterhouse on Mendip hundreds of these little black spikes, two or three inches high, appearing immediately after the snow melted after that bitter Avinter. I am of the opinion that Carex montana had been overlooked on Mendip until 1890 chiefl}" because its flowers and fruits disappear soon after Midsummer, and because many plants have no flowers. Perhaps for similar reasons I actually do not remember having collected it on the Continent, where so widely spread ; though imtil I went to Chai'terhouse in 1915 my knowledge of the j)lant was limited to having seen it growing only on shady banks in Wyre Forest and in a Sussex woodland. Since the above was w^-itten, I find the following interesting note on this plant by that careful observer the late T, R. Archei- Briggs in his Flora of Plymouth (1880) p. 351 : — " One of the earliest Car ices to flower. By the third week in June I have found the seeds all shed and the spikes withered ; but the large j^tches foi-med by its tufts of light green leaves and its thick shaggy rhizome serve, when flowers and seeds are gone, to distinguish it from its associates, C. pihtlifera dir\(\.

Ik this Journal for 1916 (pp. 226-231) I published descriptions of several new Gamopetalse collected by Mr. G. L. Bates in the Yaunde district of Southern Cameroons. most of them from the neighbourhood of Bitye, Ebolowa. Mr. Bates, who has ah-eady obtained a deserved reputation for the excellence and interest of his collections, has recently sent to the National Herbarium about 250 specimens from the same district ; over 16 per cent, of these are lluhiacecB^ among which are so many novelties as to claim a separate record ; the interest of the remainder, from the rarity and excellence of the material, is hardly less than that of the new^ species. Nott'S by Mr. Bates, which I quote in inverted commas, accom])any 276 THE JomtXAL of botani' most of the specimens : the following is an extract fi*om his letter of Jan. 30, announcing their despatch : *'.... Xearh^ all plants here [Bitye] are woody, and fully half of them, I should think, haye weak climbing stems. These latter I haye called, all, ' yines ' . . . . I use still the Bulu word ekotok \ and if you want to substitute English you ^vill haye to say * mixed growth on abandoned ground ' . . . . The natives here never keep the land under cultivation long — or properly, never under cultivation at all — and after clearing, and planting for a few seasons, they leave the wild growth to spring up again. This new growth is partly from roots and stumps left in the ground and large trees left standing at the time of clearing, and partly from seeds of certain quick-growing trees, vines and weeds characteristic of such land, and never found in the forest .... EkotoJc goes gradually back to the forest ; these quick-growing plants disappear, and true forest-growth takes their place ; * old ekotok ' is that which is turning to forest again .... Here, where there is no winter, there is no regular time of Howering of each species ; still, I am sure that a long and careful course of observation would show some kind of regularity in seasons, but it would be hard to work out." I proceed to enumerate the Rubiacese in systematic order, describing such as appear to be new. The consideration of certain critical forms is reserved for a subsequent paper.

GEORGE STEPHEN WEST, M.A., D.Sc, F.L.S. (1876-1919.) George West was born at Bradford on April 20th, 1876. The father, William West (1848-1914), of whom a notice appears in this Journal for the latter year (p. 161), had first-hand knowledge of British flowering plants and cryptogams, and his two sons helped him much : the elder, William, died in 1901 at the early age of twenty-six (see Journ. Bot. 1901, 353). George began early to specialize in the Algse, especially the Desmids. After passing through the Bradford Technical College and the Roj^al College of Science, London, he completed his education at St. John's College, Cambridge, where he was elected Hutchinson Research Student, and apjDointed demonstrator in biology to the Uniyersity. Afterwards for several j-ears he filled the post of lecturer in natural history at the Royal Agricultural College, Cirencester, and was then appointed (1906) lecturer in botany at the University of Birmingham, under the late Prof. Hillhouse, whom he commemoi'ated in that gigantic sulphur-bacterium Hillhoiisia mira- hilis. On the retirement of Hillhouse in 1909 he succeeded to his chair, and in 1916 became Mason Professor. West was an excellent teacher and lecturer, much liked by his pupils, and extremely success- ful in training them in the habit of scientific research. He greatly enlarged and improved his department ; the herbarium is almost entirely his creation. Among his post-graduate students may be mentioned Dr. Muriel Bristol and Dr. Nellie Carter, whose respective researches have thrown much light on the algse of the soil and on the forms of the chloroplasts of Desmids. West was the leading expert of this country on Freshwater Algse : he could recognise at sight almost every British Desmid. His four beautifully illustrated volumes on British Desmidiacese in the Ray Society's publications are well known ; it is hoped to publish a fifth volume based u^jon his notes. The investigations of father and son in the Desmids of the whole world made it clear that that group is peculiarly fitted to throw light on the problems of plant distribution and the evolution of species, owing to the fact that they can seldom survive desiccation even for a few hours. George West's chief publications on Algse generally were his Treatise on British Freshwater Alga? (1904, long out of print) and the volume (1916) upon the Myxoph^'cese, Peridiniea', Bacillariea?, and Chlorophycese — the first of the series of Cambridge Botanical Handbooks. — of which some account will be found in this Journal X 2 284 THE JOURNAL OF BOTANY for 1917 (p. 88). Besides these and numerous articles in this and other botanical journals, etc., on Algse from all parts of the world — the series of '' Algological Notes," begun in this Jo.urnal for 1911 and continued at intervals, mav be mentioned— West was contemplating the prej-taration of a new work on British Freshwater Algai (excluding ])iatoms and Desmids), in which he intended to describe and figure every known species : the value of such a volume can be appreciated by all who are acquainted with his skill and accuracy in drawing, and it is hoped that some part of it may be in a condition fit for publi- cation. The whole of his di-a wings of Algae are bequeathed to the British Museum ; his algological library and specimens are left to the University of Birmingham. There still remains to be mentioned his projected Algal Flora of the Midlands ; of this only a comparatively few preliminary lists are prepared, but it is hoped to publish these shortly. It is scarcely possible to imagine, apart from calcareous districts, a more unpromising area in this country for algse than that round Birmingham, yet West and his zealous helpers showed that even this could yield riches, inchiding such a rarit}^ as a new Boya in conjugation, probably the first that has ever been found in Britain in that condition. He proved again that, when a competent botanist settles down in a new Lcality, it begins at once to yield a previously unsusj^ected wealth of material. West died at Edgbaston on August 7th after a brief ilhiess. The cause was a seve]-e attack of double pneumonia, aggravated b}^ the weakness due to his indifferent health during the last few years, for he never recovered completely from the influenza trouble of four years ago. He leaves a widow and two young sons, and his premature decease at the early age of forty-three deprives British natural science of one of its most promising adherents. The loss of his kindly encouragement and help to the eager band which he had gathered round him leaves a gap which will be difiicult to fill. W. B. G. SHOKT NOTES. YACCTNirM INTERMEDIUM Ruthc (p. 259). One locality for this plant in Caithness is a gorge of the Achorn Burn, a tributary of the Dunbeath Water on the east coast: this is locally a deep shadj^ chasm in the rocks, but the higher parts of the walls are exposed to sunlight "' (C. B. Crampton, Vegefafion of Cff/fJmess etc., p. 94: 1911). One plant only was found, with the parents and Arctostaphylos Vva-iirsi. Here there can hardly have been human interference. The other locality, whence I have a specimen collected by Mr. Sutherland, is Scarmclett Braes near Watten near a large lake ; the only evidence of human interference in the neighbourhood is the existence of two ■**picts' houses." The North Lancashire locality (Coniston Old Man, 2000 ft.), communicated to me by Mr. Pearsall (whose son, in company with Mr. Adamson, found it there in 1914), and the Stafford- shire habitat, Norton Bog, 1898 (Bagnall, Fl. Staff, p. 40), seem equally I'emote from human influence. Mr. Garner informed me that SHORT XOTES 28o the first finder of the plant in Staffordshire was a surgeon, Mr. D. Ball. In Science Gossip for 1872 (p. 248) Mr. G-arner figured and described it as "a Curious British Plant " ; he there says "The Maer and Camp Hills were planted by Mr. Wedge wood, the eminent potter."

He adds : "I had the opportunity of going to Maer Wood where the plant was originally discovered ; we found four patches of the hybrid, including one rery extensive and old patch which might well be the original one discovered in 1870.

A small quantity of the ' Branksome Lily ' still exists in the old locality ; but I saw no more than four or five plants, when at Bournemoatli in June of this year. Mr. Rogers tells me that it crops up every now and then in grassy waste by the side of roads ; so that, though building and dumping operations have sadly restricted the area of its occurrence, there is a good hope of its not entirely disappearing from the neighbourliood. H. J. ElDDELSDELL. Mtmflus moschatus L. Reference has been made from time to time in the horticultural journals and in our ovv'n pages to the general scentlessness of this plant. A note in The Garden for Sept. 6 states that a fine plant was seen at Feltham, Middlesex, which was very strongly scented ; it came from a small nurseryman in the neighbour- hood, who at the time said it was not scented, but it certainly became so. From this it would seem that the scent appears and disappears in the same plant. — Ed. Journ. Bot. X Potamogetox dtjallts Hagstrom (P. panormitanus Biv. x pusillus L.). Dr. Hagstrom in his Critical Researches in Potamo- geion (p. 103) describes the above hybrid, and mentions specimens from "Ponds near York (1881) Bennett, and Shropshire (1886) Beekwith." These I have looked up; both specimens were sent by me and are now in the Stockholm herbarium. I also find specimens of P. panormitanus Biv., from Ireland as "P. pusillus L. var. tenuissinms Koch. Off Harbour Island, Lough ISTeagh, Co. Antrim. 10 Aug. 1909, C. H. Waddell." It is probably fairly distributed in this count}', but all specimens need examination as to whether they are this or pusillus. — Arthur Benxett. Sex-terms eor Plants. I was much surprised to read Mr. Church's criticism of the use by 'Mr. Chamberlain of the term "female " in relation to a tree (p. 230), and still more at his sugges- tion to substitute for it the word "fruiting." It seems to me that "female" is quite a satisfactory term: it is a good plain strong English word, and, pace Mr. Church, an unambiguous one having but a single meaning, therefore surely an ideal scientific term. The term " fruiting," on the other hand, is open to grave objection. It 286 THE JOURNAL OF BOTANY can of course be correctly used to denote the stage of development of a plant to contrast, say, with " dowering," and it can also be correctly used in contrast to " sterile " ; but as an antonym of " male/' for which I gather Mr. Church proposes to use it, I should have thought it impossible. Just now long words with Greek roots are, one realizes, much in fashion, ; but really Mr. Church's suggestion of the use of two prefixes, which merely mean " large " and " small," for purposes of sex-differentiation seems ])reposterous, and to my thinking the sooner such misleading terms are " scrapped," to use Mr. Church's expression, the better in the interests of accuracy. Your contributor would appear to have some objection to the recognition of sex in plants, but I may be pardoned for suggesting that the use of am- bisruous verbiau'e will not do awaA^ with the fact. — James Geo yes. Pollination of Vtscum album. Following some experiments on the fertilization of Mistletoe by Dom Ethelbert Home, as recorded by him at length in this Journal for 1916 (p. -92), and again in a shorter note in the volume for 1918 (p. 331), and guided by some advice from him about protecting the blooms for trial, four flowering twigs of a female plant were enclosed in fine hexagonal cotton net with a 1 mm. mesh. The net was kept clear of the blooms by a framework of thin split cane ; two little hoops of this wei'e tied across each other at the top, the ends being then brought down to the .stem, where they and the net covering, now of balloon shape, were securely tied. There is no male plant in the garden, but twigs of pollen bloom were obtained from a distance and hung up in the female l)ush. The uncovered part of the bush, especially on the sunny side, became loaded with berries. Of the four enclosed twigs, two have one berry each, the other two none. It may be surmised that some of the pollen may have been caught and retained by the fine net, or all of it in the case of the flowers where no fertilisation was effected. In any case, this experiment, agreeing with former trials b}^ Dom Ethelbert, would support his view that fertilisation is not necessarily due to the agency of insects, for none of the bees and flies, claimed b}^ the natumlists Koelreuter, Kirschner, and Loew to be conveyors of the jioUen, could possibly pass through the small meshed net. Gertrude Jekyll. Galium erectum in Somerset. When Murray's Flora of Somerset was published in 1896 there was only one undoubted record for this plant in the county of Somerset, and that was from a wall near Templecombe — a strange habitat. Since then it has been found in several localities in X. and S. Somerset (see Marshall's Siipplemen/). On June 7th this year, in walking up to Sidcot School from Winscombe Station, by the old and much frequented foot-path through the fields, I noticed in the top enclosure, close to the main road to Bristol, numerous patches of Galium erect um in the short mowing grass. The plant was vaiiable in form, colour, and stature. Some were very short, and others somewhat like the upland Mendip form of G. Mollugo, the type of which grows in a lane adjoining and on the main road. Further search showed that G. erectum was disli'ihuted in patches over the greater part of the field. On enquiry SHORT NOTES 287 I learned that this pasture had been browsed by sheep for " at least 40 years " since it had been ploughed ; and it was never mown until this year. This doubtless explains why the plant had never been noticed, or at least recorded, from a place within 200 yards of the Sidcot School premises and through which generations of young naturalists and not a few older botanists must have passed. Already by June loth the flowers had largely disappeared \^\t is well known to blossom at least three weeks earlier than Mollur/o) ; and on August 1st I could not find a trace of even the leaves. The short grass had been mown a fortnight earlier, and a horse was now in possession. Such plants as Cniciis acaulis, however, threw a further liglit on the cultural history of that pasture. Apparently certain Bedstraws are appreciated by stock, especially in dry weather. The day after my discovery I was surprised to find patches of good G. erectum in grass left to be mown on both sides of the private drive to Newcomb, Sidcot, a quarter of a mile on the other side of the School. This drive was made some 12 years ago, and was cut out of a pasture grazed by cows. 1 regard the Sidcot locality and that on a Lias pasture near Washford in the west of the county as the most satisfactory stations for Galium, ei^ectum in the whole of the Bristol and Somerset area.— H. S. Thompson. Hypericum humietjsum (pp. 195, 225). The notes on the distribution of this plant lead me to record that on 9th Sept. I saw it in great quantity in a gravelly field on a hillside in the neighbour- hood of Newton Abbot, S. Devon. The abundant flowers gave quite a tinge of colour to the upper part of this field, which was at the edge of a dense wood, and bracken -bordered. The form was a somewhat diminutive one, which might be accounted for by the position, ex- posed to strong sunlight, and by the very dry season. — C E. Larteh. EEVIEWS. Lectures on Sex and Heredity, delivered in Glasgow, 1917-18, by F. 0. Bower, J. Graham Kerr, and W. E. Agar. Macmillan & Co., London, 1919; 16mo, pp. vi4-119. Price 5s. A CLEAR understanding of the mechanism of reproduction is admittedly of primary necessity to biologists and economists of every grade, and this pleasant little production epitomizes much of modern views. The word ' ' sex " is still commonly used to cover two distinct sets of phenomena : (1) syngamy, the fusion of two gamete nuclei to give a new individual — a phenomenon of fundamental importance as leading to consequent meiosis with its differentiation of inheritance and new possibilities of racial variation, with nothing " male " or " female " about it, the latter terms being merely human conventions, as applied to phenomena of (2) heterogamy and the differentiation of sexual characters — as a set of factors concerned solely with the secondary, post-syngamic, nutrition of the zygote, and its further consequences as expressed in " maleness " and "femaleness." Such phenomena in the botanical kingdom range from the simplest isogamy, and even complete absence of nucleogamy, to advanced heterogamy with manifold secondary diiferentiations, as also the 28$ THE .TOUR^'AL OF BOTANY ultimate complete supersession of heterogamy in the fusing units ; though the complexities of somatic di^erentiation may continue eifective. Among animals a very uniform and almost monotonous scheme of heterogamy obtains, from the lowest Metazoa to the higliest, and the subject is hence considered from a broader standpoint in Botany. Professor Bower gives a simple account, stripped of all unnecessary technicalities, of the general facts of plant-reproduction, tracing the progress of sexual differentiation through the vegetable kingdom, from the water to the land, including the elaborated mechanism for post-sexual nutrition Avithin the seeds of higher land-plants. It is edifying to note that Professor Bower in this connection (p. 50) tilts against Tennyson for writing " How [sic] careless of the single life," because the poet was not thinking of something entirely different which had appealed to the botanist, in reference to the infinite care taken by the organism (not " Nature ") to protect what he calls the "germ" ; ignoring the fact to which Tenn^^son was alluding — ?'. e. that, notwith- standing every such precaution, the seed is ulthnately exposed to the caprices of " Nature," and it is in the stage of the resting seed, rather than in germination, that the most appalling wastage of the race has to be endured. The account of sexual reproduction from the animal side is put so very' briefly and concisely, that one does it the compHment of wanting more. The comparison of the human ovum with the gametes of a seaweed (p. 5) affords an interesting reminder that the highest organisms, having passed through the Reptilian epoch, have come back to a state practically identical with that of an alga ; the com- parison would have been more effective if the oosphereof Himanthalia or Sargassum had been figured instead of Fiicus. Hence zoology passes on to more intimate phenomena of nuclear S3nigamy, and t]ie possible mechanism of heredity. The Weismannic conception of germ-plasm, so foreign to a botanist, is utilized to bar out the inheritance of acquired characters, to the discomfiture of many educationalists and sociologists who hope for immediate results. Mendelism is introduced in the person of the Blue Andalusian fowl, and pleasing facts are recorded as to the inheritance of insanit}^ and brachydactyly. An implied delicate compliment to the presumed intellectuality of the teaching profession is expressed by its position at the head of the table of falling birth-rates ; though it might be argued that a man who expects to make a living by teaching others is ipso facto " unfit." One cannot expect much more in only about a hundred small pages, but a short list of references to the more reliable literature of the subject might have been added. A. H. C. The Building of an Autotrophic Flagellate. By A. H. C'ui'rch. Botanical Memoirs No. 1. Oxford University Press. 1919. 27 pp. Price 2s. Ix a score of crisply written chapters, closely packed with facts and deductions, Dr. A. H. Church gives us a reasoned argument descriptive of the origin and development of the simple self-supporting THE BUILDIXa OF AX AUTOTROPHIC FLAGELLATE 289 plankton-cell in sea-water. He insists that it is in the vast, constant^ ionized ocean that the first hazy rudiments of life began to be (problems for the phj^sicist and chemist to unravel) ; that carbo- h\^drates were formed and increased in complexity, thanks to the peculiar linking properties of the carbon-atom, and led on to colloid- formation ; that nitrogen was pressed into service and was added to the mobile composition of the plasma; and that, when means had' been evolved for utilising solar energy, an autotrophic organisation had come into existence capable of producing an ever increasing out- put of carbohydrate and proteid, and of carrying on life indefinitely. The subject thus became a botanical problem. Owing to the scarcity of nitrogen compounds in the sea, the manufacture of carbohydrates was necessarily far in excess of the proteid synthesis, and consequently tbere were great quantities of carbohydrate waste to be got rid of, either in a soluble form, or by storage, or preferably as an insoluble polysaccharide deposit on the periphery of the plant — thereby origin- ating a mucilaginous or cellulose wall. Thus " chemical linkage " and '* physical growth by adsorption " progressed. The plasma prospered in the daylight, but by night it had to live upon its own reserves ; in this wa_y katabolism was initiated and a certain indepen- dence attained — an independence which conduced to the possibility of animal life. The delicate plasma necessarily assumed a spherical form by reason of surface tension. Surface tension and metabolic activity would be associated with contractility. Further, a " differ- entiation " of the plasma '• into at least three regions may be postu- lated " : (1) the surface or plasmatic film ; (2) an illuminated metaboHc zone — the chloroplasm ; (3) a central region — the nucleo- plasm— living at the expense of the outer zones and free to assume the control of the organism. As the spherical plankton-cell tends to sink vertically, which would be fatal, a tremendous advantage would be gained if the organism could contrive to rise up by growth towards the lessening light. Thus polarity is assumed to have be- come established — with the subsequent development of a flagellum, however rudimentary, which served primarilj^ as an "anterior tractor- mechanism " and subsequently became exploited in many cases as a food-gatherer. A great advance was achieved when binarj^ fission superseded the mere fragmentation due to sea-action, such fission being presumed to originate in the deep-seated nucleoplasm where starvation would first be felt. The author, in discussing failure and death, argues that " under pressure of approaching dissolution new departures . . . new racial improvements . . . ma}^ be . . . expected to occur," namely, the evolution of sexuality, of the holozoic animal, of benthic plants and animals. The later chapters treat of holozoie nutrition, the origin of sexual fusion, the differentiation of flagella, the formation of the cell-wall. Step by step the author works out his case, showing how in- evitably phase has followed phase in the scheme of evolution — a scheme which was " settled once for all time in the initiation of minute forms of ultra-microscopic life, as the necessary outcome of the physical and chemical organization of the aqueous phase of the sea itself."

G. A 3Io7iograj)h of the Gemis Alaria. By Professor K. Yexdo (Journal of the College of Science, Imperial University of Tokyo, vol. xliii. 1919 : 145 pages, 19 plates). Thts is a valuable addition to our knowledge of the Brown Algae. In addition to submitting the species to a critical revision and reducing them to 15 — some 32 have been described since Greville established the genus in 1830, — the author discusses in his introduction several matters of great interest in relation to the anatomy, morphology, habit, and life-history of Alaria and its allies among the Laminariaceae. The shape of the lamina is untrustworthy as a systematic character for its width varies with the environment ; so also does its thickness and toughness ; and the rapidity of growth pf the frond is astound- ing ; in three or four months the frond of such a colossal plant as the N. Pacific A. Jistulosa may attain a length of as much as 60-80 feet or even more. This species is remarkable for its hollow midrib septated at irregular intervals, which serves as a float for the lamina. A close study of the development of the sporophylls has led the author to divide the species into two groups, Holosoria and Metasoria. In the former the sporophylls are thick and coria- ceous from the first and become covered with sori. In the latter, to which our one British species belongs, the sporophylls are membranaceous at first ; and this part remains sterile and more or less gets worn away, while a new and thicker growth ai'ises below it and becomes soriferous. The meaning of the cryptostomata has been much discussed. Prof. Yendo sums up our knowledge of these structures in the different families of Brown Alga? and concludes that in the Laminariaceae the hair- tufts can safely be regarded as a sort of al)sorptive organ. The presence of mucilage glands in the various species of Alaria is described ; but mucilage canals are absent. Occasionally monstrosities occur such as duplication of the lamina or ramification of the stipes, "AL OF BOTANY The Presidentml Address of Sir Daniel Morris to the Botanical Section of the British Association at its recent meeting at Bournemouth included a useful summary of recent botanical research in this country, but was mainly devoted to a very interesting and comprehensive review of " the many efforts that have been made, and are still being made, to 'promote the interests not only of the home land but of the Empire as a whole." The work of the Imperial Department of Agriculture in the West Indies in connection with the sugar-cane is summarized ; there is an account of the investigations into wheat- breeding on Mendel ian lines carried on by BiSen at Cambridge and in India by the Howards, which " clearly demonstrates the value of thorough acquaintance with pure botany as a qualification for grappling with questions of economic importance " ; cotton and its diseases come under consideration, as does rubber and its diseases. The account of the development of the cacao industr}^ on the Gold Coast, which Sir Daniel regards as " probably the most remarkable instance on record of the successful combination of science and enterprise in the Tropics," ma}^ be quoted: "Thirty years ago no cacao of any kind was produced on the Coast. Owing, however, to the foresight of the then Governor (Sir William Brandford Griffith), who sought the powerful aid of Kew, cacao growing was started in a small way among the negro peasantr}^ with eventually extraordinary results. After selecting the locality for the experiments, seeds and plants were obtained through Kew, and a trained man was placed in charge. The first exports in 1891 amounted to a value of £4 only. So rapid was the development of the industry that ten years later the exjDorts reached a value of £43,000. By this time both the people and the Government had begun to realise the possibilities of the situation, and s^^stematic steps were taken to organise under scientific control a sta:ff of travelling agricultm-al instructors to advise and assist the cultivators in dealing with fungoid and insect pests and improve the qualit}" of the produce. In 1911 the exports had increased nearly fourfold, and reached a total value of £1,613,000, while in 1916, what may possibly be regarded as the maxinuun exports, were of the value of £3,847,720."

To the algologists of the last century, as soon as the vegetation of the tide-range began to be familiar, and Red Algaj were differen- tiated from the larger Fuci, the Floridese proved at once an attractive and wholly mysterious race of organism, tlie types of which in their kaleidoscopic variety of form, the transient charm of their rosy coloration, so different from the predominant green of land- vegeta- tion, and their delicate texture and ramitieation, have been very generally accepted as representing tlie culminating race of marine algse. Yet many are stout strong f)lants, attaining to a bushy mass 3-6 ft. in length, and the residual tj^pes of the tide-range may present no special attraction either in colour or form, though valued from an economic standpoint and utilised as food by man and cattle. The observations of Bornet and Thuret on the nature of their reproductive processes, so distinct from the general flagellated mechanism of other algal phjda, added to the wonder of the group ; and the more the t3^pes have been investigated the more mysterious have appeared their special attributes : only within the last few years has the general scheme of the Life-cycle been rendered clear, and its relation to that of other algal phyla made intelligible. All these features appear the more remarkable as this strange algal race, living in the sea — by no means relegated to deep water as is popularly supposed, but side by side with other residual phyla of ' green ' and ' brown ' algse, — still holds its own in more quiet en- vironment as a race of marine phyt^benthon which has passed to the limit of marine possibility in its reproductive processes. In so doing it throws a curious light on the historj^ of the early sea, as also on the possibility of the landward migration of comparable algal forms to constitute the flora of the land — whether as higher types of auto- trophic vegetation, or as reduced and heterotrophic fungi. In the collection and elucidation of the multitudinous forms so far included in this isolated group, the jDioneer algologists of this country have done perhaps more than those of any other in establishing the foundations of the subject ; though in more recent years the more critical work has been done elsewhere, as laboratory technique replaces shore-collection and the cult of the sea-weed album. Once it is understood that the best plants in optimum growth can be only obtained by dredging in the sub-littoral zone, and that the highest laborator}^ technique is required to bring out the most essential details, the plants are largely relegated to the cytological expert. But much remains to be done in other directions of structure and anatomy, the physiology of metabolism, oecological relations, and above all in culture, which is within the scope of the most elementary laboratory practice ; and a wide field still remains open to the algolo- gists of this country, as also to those of British colonies with even hner subtropical reptresentatives of the group. The history of the Florideae in its earlier phases is bound up with JouRKAL or Botany. — Vol. 57.

In Theophrastus the most definite reference to a Floridean is that of the "Sea-Palm." The text^ gives a good idea of the diffi- culty of an early naturalist in wrestling with the morphology of a sea- Aveed ; and the"^ Sea-Palm {Palma marina) became a stock article with early writers. It is interesting to note that the text describes the plant as (palvil, although the Greeks do not seem to hare distin- guished the pinnate Phoenix from the palmate bushy Chamcerops ; as also to make it quite clear that there was no allusion to a lobed sea- weed like the palm of a hand : the midrib is described, and the torn appeamnce of the laminae which gave the pinnate character to the fronds; the latter evidently grew in tufts of leaf-like members, Avhicli were not irregularly lobed and crumpled. The plant has been generally identified Avith the bright red CaUophyllis laviniatn, but this is certainly a mistake ^.

The convention of Fucus and Conferva died hard ; the definition of the latter had been given by LinnfBUs as Alga capillaris, and according to Dillwyn ^ it included Polj^siphonias, Ceramiums, and even JDasya coccinea ; yet Goodenough and Woodward^ (1795) included as Fuci such plants as Boli/si- 2)honia hyssoides, BostrycMa, and Bonnemaisonia. The history of the Florideae as a class begins with the separation of the group under this special name by Lamoueoux (1813) i^ ; the eleven genera — Glaiidea, Delesseria, Ghondrus, Oelidiumy Laurencia, Sypneay Acantlioplioray Dumontia, Giyartina, Plocamium, and Champia, are localized under the heading Florideae, although the colour-guide was still a little vague ; Furcellaria was left with the Fucaceae from its dark colour, and Amansia, as presenting a ' net- work ' surface, Avith the Dictyotaceae. Lyngbye ii added genera, as Lomentaria and CalUthamnion, but had the genera all mixed up on a system of his own ; the Florideae not being separated from Brown Algae : the idea did not make Avay at once ; the colour-guide was treacherous.

The science has grown up with the elegant Gallicized forms as Claudea, Champia, Amansia, Dumontia, Delesseria, Laurencia, and future generations may assimilate Proto-Kuetzingia, Schmitziella, and Heterojnnczevs'kia.

Curiously enough, Greville^, as late as 1830, still keeps the tradition of the diehotoraous Polgides and Furcellaria as near Dictyota dicliotoma, and beyond the pale of the true Floridese, not- withstanding the brightness of the crimson coloration of his plate -. The accumulation of genera and species, and the marking out of the main series by differentiation of somatic organization, was the work of the collectors and svsteniatists, more particularly of the first half of the XlXth Century; cf. Lightfoot (1777), Hudson (1768), Goodenough and Woodward (1795), Yelley (1795), Stackhouse (1795), Dawson Turner (1808), Dillvyyn and Hooker (1809) ; cf.

In more recent times this work has been amplified for British coasts by Buffc'ham (tl896; JBuffhamia, Holmes {HoJmesia) and more particularly by E. A. L. Batters (f 1907 ; Battersia), whose list of British Marine Algae (Journ. Bot., Supp. 1902) remains the standard authority, and Trail (f 1919 ; Trailiella). For this country the work culminates in the two volumes of the Bhycologici Britannica of Harvey (1845-1851) containing descriptions and coloured plates of 182 species, arranged in 52 genera and 7 orders. As works of the same epoch may be included : — Species, Genera et Ordines Florideao'um of J. Agardh (Lund, 1851-1876), Iconogrcrphica Bhycologia Adriatica of Zanardini (Venice, 1860), audi Phycologia Mcditerranea of Ardissone (1883). To the collectors of the early part of the Nineteenth Century is larg-dy due the rapid growth in the study of algaj which marks t'le difference between the works of Haryey (1851), Fhycologia Britannica, Nereis Bor. Amer. (1851), Bhycolog. Anstralica (1858- 63), and the volumes of Stackhouse and Dawson Turner. Outside the range of the Flowering Plants and Ferns, no other group of the veo-etable kingdom has been so popularized as the Floridea^, in this ^ Greville (Edinburgh, 1830), Algx Britannicas. 2 For the older restriction of the order ' Florideae,' cf.

The facility with which really astonishing pictures, with a beauty of lijie and colouring, beyond ordinary dmughtmanship, were to be produced, in an age when mechanical productions of artistic value were so defective, led to the establishing of the cult of the sea- weed album, and the formation of such a volume came to be regarded as a ix)lite accomplishment eminently suitable for ladies of taste and leisure. Many of these books survive to the present day, when sea-weed mounting is almost a lost art, G. Brebner (tl905) being one of the last exponents ; and it is still interesting to appreciate the skilled manipulation of a fine specimen. It is curious to note how the British Floridese lend themselves to such pictorial display, being usually of a most convenient size; the larger Brown Algse were allowed to complete the collection, rather in the form of 'juvenile phases ' ; i. e. Laminarians less than a foot in length. Kuetzing (1843) in his Fhycologia Generalis alone exhibits a more extended outlook of more modern botany, by the incorporation of many detailed anatomical and physiological considerations, to- gether with a large number of drawings made from careful sections, some of which have done duty in text-books to the present dav. Similar work for the world at large, as continued to the present time, has extended the list to over 3000 species, which are found enume- rated by De Toni i (1897-1905), of which about 300 are listed for the British Coast by Batters (1902) -, Beyond what may be termed the book-keeping of the subject, the great advances that have been made in our knowledge of the life- history of these plants, are due to the work of relatively few observers ; certain papers stand out 2)rominently as indicating epochs in the progress of the science, as again expressive of new mental attitudes and view-points in dealing with the plants, these being more or less reflected into the subject from the general advance in other fields of botanical research. I. Of these epochs the first is that indicated by the observations of BoRNET and Thuret ^ on the French coast of the Channel and at Biarritz, in connection with the question, more particularly, of sexual reproduction, and following the lines of similar work on the Brown Seaweeds : the significance of sexuality, and the nature of the repro- ductive organs, being established for about a dozen genera, including such forms as Nemalion, Helmintliora, Callithamnion cori/mhosiim, Lejolisia, Dudresnaya. Much of the work sj)read over twenty years was collected in the classical volume of the htudes JPliycologigues, with beautiful aquatint plates from drawings by Eiocreux, which as faithful representations of the living plant-tissues, as actually seen fresh under the microscope, without distortion or conventional repre- sentation, have never been surj^assed. ^ DeToni (Patavii, 1897-1905), Sijlloge AUjarum, vol. iv.

A second epoch, based on the researches of Schmitz^ (1883), was devoted more particularly to the detailed examination of the problems connected with the development of the cystocarp, the nature of tlie cell-fusions, and what was, perhaps, reall}' of more consequence — the regrouping of the families and genera in accordance with the nature of the reproductive phenomena in the Life- Cycle, rather than by somatic organization and the external morphology of the adult structures alone, as in the artiticial systems of J. Agardh and Harvey. Although what Schmitz regarded as the essential point of his work — the sexual nature of the cytoplasmic fusion with auxiliary cells, as expressive of a mysterious phenomenon of * double-fertiliza- tion,'— has not stood the test of time, as it did not that of the "tradition" of his day, the 1888 paper contains a neat exposition of the theorj'' of the Florideae as a whole, which gives it a text-book value. The more detailed S3^stematic scheme of Schmitz, left un- finished at his death, is found in the section of the PJlanzenfamilien of Engler and Prantl (Schmitz and Hauptfleisch, 1896), and is the basis of the modern presentation of the group. There can be no doubt that the Florideae acquired a special vogue of mj^stery in virtue of Schmitz's claims of the significance of auxiliary cells in * double fertilization ' ; but with further knowledge of sexual mechanism, deduced from observation of other branches of the vegetable kingdom, at hand, such assumptions are seen to be wholl}' unauthorized, and th(? entire edifice of classification erected on it is left witliout sure foundation. However, the series and orders of Schmitz have now become established and incorporated in botanical literature-, largely through the agenc}^ of the valuable volumes of He Toni, and there is little to be gained by altering them until there may be satisfactory grounds for recasting the entire subject^. On the other hand the attempted phylogenetic arrangement of Schmitz (1889-1897) marks so definite an advance on preceding systems, that all nomenclature may be conveniently checked at the latter date. III. In a paper Avhich also attains classical rank Oltmaxns '^ succeeded in demonstrating in a perfectly convincing manner the exact significance of these secondary fusions with auxiliary cells, and traced the mutual relations of the nuclei in the process ; details are described for five well-defined leading types, as Dudresnai/a piir- ^ Solimitz (Berlin, 1883), TJntersuchungen ilberdie Befrn^htung der Florideen : an English translation is more readily accessible, cf.

Friedrich Schmitz, of Greifswald, died 1895, will always be known as the greatest investigator of the Ploridefe, during the latter half of the nineteenth (iontury. He served through the Franco-Prussian war, and was first attracted to sea- weeds while on duty on the coast of Normandy. Most of his material was obtained from Naples, and only those who have a tide-range to forage on can appreciate the handicap of working entirely with preserved material, or on specimens collected by other people.

HISTORICAL EEYIEW OF THE FLOBIDEJ: 303 jpurifera and D. cocciiiea, Gloiosiplionia, Dasya, and Callithamnion, the jDeculiar nuclear phenomena, as also cytojDlasmic fusion, being solely the expressions of an attempt to obtain food-supplies for the parasitic genei-ation. This has placed the question of the nutrition of the carposporophyte on a rational basis, and older views on the sexual significance of cytoplasmic fusions, unavoidably obscure so lon^i- as the essential nuclear phenomena were little known, even in the case of higher plants, have been relegated to their proper place. IV. In more recent times the attention paid since 189-i to the cytological details of diploid phases as associated with the familiar alternation of generations in the life-history of land-plants, and as constituting a causal factor for the differentiation of gametophvte and sporophyte, has led to a more thorough investigation of the reproductive organization of the Floridese. In a paper on I^olysi- phonia vlolacea, SiiiaEO Yama^s'ouchi ^ (Chicago, 1906), the cytological relation of the diiferent individuals of the trimorphic sequence involved in the life-cycle was clearly established as a model for similar w^ork on other forms, as the necessity for the use of the microtome and the best methods of modern technique was success- fully vindicated. So long as algologists could make out nine-tenths of the facts by simple section-cutting, or ' squeezing-out ' methods, the use of the microtome was avoided ; and though the imjjortance of nuclear phenomena may have been exaggerated, these latter are an essential part of the story, and cannot be omitted. However much can be done even better without it ; in dealing Avith the general anatomy and most of the reproductive processes, more particularlv as presented in fresh material, the microtome remains as the last appeal in all cytoplasmic research. Even more recently the Floridese maintain their value as con- tributing to the solution of much debated problems of reproductive mechanism common to higher organism. The demonstration by Stedelius 2 of the fact that in such forms as Scinaia (as also by Kylin ^ and Cleland for Ne7nalion) the cytological alternation of haploid and diploid nuclear phases need not necessarily run conform- ably with the morphological alternation of gametoph^^te and sporo- phyte individuals, bids fair to remove the curious obsession of botanists (dating to Strasburger '^, 1894) that such cytological mechanism of the nucleus can ever be a satisfactor}-- causal factor in the differentia- ^ Yamanouchi (Chicago, 1906), Bot.

Bot. p. 323. ^ Strasbvirger (1894) may be said to have initiated the idea that since the gametophyte of land plants is haploid in its chromosome number, and the sporo- phyte is diploid, therefore any haploid stage must be a gametophyte, and any diploid generation a sporophyte : a curious non aequitur which has been very generally accepted. There cannot be more than two cytological phases, haploid or diploid, but there may be more than two morphologically differentiated stages in a life-cycle ; e. g. the Floridese have three, hence commonly manipulated to make two, in order to suit a preconceived academic scheme. 304 THE JOURNAL OF BOTANY tlon of a complex life-cycle, thus squeezed into an academic two-phase scheme ^. V. Also within the present generation, the Florideae share in the new outlook on the science which has been opened up under the heading of CEcology =^ (Warming, 1896). This special line of investigation is designed to replace the rule-of- thumb methods of the older school of naturalists, and to analyze and tabulate the enormous amount of ' general information ' acquired subconsciously by the older ' collector,' which largely constituted the charm of out-door investigations. The difficulties of the problems presented by the Florideae are enormous, and can be only overcome b}^ long-continued and careful work ; the main held of research being invisible to the human eye, submarine, beyond the reach of either direct observation or experi- ment, and only to be explored by dredging and the use of deep-sea instruments — often on dangerous rocky ground — at all seasons of the year. The vegetation of the tide-range inevitably receives at first an exaggerated amount of attention : all such vegetation is of a depaupe- rated character, and by no means representative of the main sti-ength of the inventive genius of the group. The same applies with even greater force to the reduced and hardy relics characteristic of the more extreme positions in zones above the high-tide mark, the case of dark caves, the vegetation of the salt-marsh, brackish water, and extension into freshwater streams and ditches. Owing to their more ready accessibihty, and their association with more interesting types of land-vegetation, these depauperated wastrels of the sea are in danger of being given a degree of prominence out of all proportion to their essential value, either morphologically or phylogenetically. The true vegetation of the sea is in the sea, and may be said to begin at low-tide level. BAIIBAIIEA EIVULARIS IN BRITAIN. Br A. B. Jackson, A.L.S., and A. J. Wilmott, F.L.S. At first sight it Avould appear from Mr, Marshall's account of this plant (auf(\ p. 211), that we have an addition to our Britisli species of Barbarea, but in realit}'- it is nothing of the kind. Mr. Marsliall seems to have forgotten the paper on Barharea vul- f/aris (Journ. Bot. lOlG, 202), in which B. rivularis Martr. Don. has been fully dealt Avith jind shown to be merely a synon^'m of B. vul<)aris var. silvestris Fr.

BAIIBAHEA RIVULARIS IN BRITAIN 305 fruited form regarded by Rouy and Foueaud as the type, for which they cite Billot exs. 3011 (as B. stricta). These exsiccata have the siliques in some cases not more than 12 mm. long, so it will be seen that in plants with siliques *' double as long " these need not be longer than those of typical B. vulgaris. The British plants of var. silvestris have the fruits of normal length, and Mr. Miller's. plant from Cossington which Mr. Marshall has kindly sent us is in no way different. We cannot find, however, that Martrin-Donos states that his B. rivularis was the short-fruited form, while Carion says of his B. vulgaris var. longisiUquosa that it differs yrow typ^t with which it grows intermingled, by its *' siliques tres longues, tres. nombreuses et rapprochees de I'axe." The specimen Mr. Marshall refers to the var. longisiUquosa has siliques scarcely, if at all, longer than in those which he considers may be type, and all are of the- same length as in typical B. vulgaris, neither shorter nor longer. We have not yet seen in this coun.try any specimens of the var, silvestris with siliques of other than typical length, and it was- because of this fact that the matter was not more fully detailed in the paper mentioned above. We regard it as unsafe to accept without* verification the accounts given in Kouy and Foueaud, although they are often very valuable. The strict-fruited form of B. vulgaris has often been confused with the true B. stricta, even by such well-known authorities as Babington and Newbould, but no one who has seen true B. stricta in the living state would be likely to confuse the two. Mr, Marshall,, misled no doubt by the inadequate description of B. stricta given by Jlouy and Foueaud, contends that our British B. stricta is only B. rivularis. Unfortunately he has overlooked the important con- tribution to our knowledge of B. stricta by Messrs. Sprague and Hutchinson (Journ. Bot. 1908, 106), where the diagnosis of the two plants are so clearly set out as to leave no doubt as to their distinction.. Mr. Marshall says that the Cossington specimens show a complete- agreement with examples of B. stricta in his herbarium from Clifton Ings (not Thirsk) and Upton on Sevei'n, both of which had beera confirmed by us and one by Murbeck. A careful comparison of these specimens shows the resemblance to be merely superficial. The colour and shape of the petals do not in the least suggest B. stricta : they are obovate, bright yellow with a whitish claw, while those of the- specimens of B. stricta have the petals much narrower in outline and of a different shade of yellovv (more lemon yellow) all over. What is more important still, the fiower-buds are distinctly hairy in tlie same specimens, while those of the Cossington plant are ^j^i^/^'e glabrous.. We have measured the length of the styles in ten fruits of each of the gatherings in question, and the averages are : — Cossington 2"4 mm.,. Upton 1-8 mm., Clifton Ings I'G mm. Moreover, those of the first taper and are less than '3 mm. broad, whije those of the B. stricta are stout and truncate, '4 and -5 mm. broad respectively. Thes(^' measurements correspond to a \ery real difference in appearance. We consider the question of the shape and size of the lateral lobes of the leaves to be of subsidiary importance and unreliable for 306 THE JOUHNAL OF BOTANY diao-nosls, for in some specimens we have seen of typical B. vulgaris the lateral lobes have remained small and undeveloped. We think it just possible that Mr. Marshall is right in considering that the figure given by S^mie for B. sfricta is really B. rivularis, i. e., B. vulgaris var. silvestris. The matter was not mentioned in the previous paper because we could not decide that there was suffi- cient on the plate to determine which of the two it was better placed under, and we are still undecided. There is little in the text to show that Syme either knew or was able to discriminate between the two plants. Both grow in Yorkshire, which Syme especially mentions, and he may have confused them as so many others have done. NOTES ON BEDFOEDSHIKE PLANTS. Br J. E. Little, M.A. The Flora of Bedfordshire has during the present century received attention in three publications. The Victoria County His- tory of Beds (i. pp. 37-67 ; Constable, 190^) deals with the Botany of "^the county generally in articles by J. Hamson and G. C. Druce, assisted by James Saunders and E. M. Holmes. In 1906 Mr. J. Hamson published Aii Account of the Flora of Bedfordshire (Beds Times Publishing Co., Bedford), and Mr. James Saunders gathered too-ether various contributions which he had ])reviously made in The Field Flowers of Bedfordshire (W. F. Bunker, Luton, 1911). The following paper presents a selection of records supplementary to the last-mentioned. Mr. AV. Hillhouse, in the Transactions of the Beds Natural History Society (F. Thompson & Son, High St., Bedford), proposed in his paper " On the Surface Geology and Physical Geography of Beds " (pp. 83-91) that the county should be subdivided according to its main geological features into two districts, a northern (chiefly clay) and a southern (chiefl^^ cretaceous), the former being cut up into four, and the latter into three sub- districts, and each of the .sub-districts being again parcelled into seven portions. Thus in fact forty-nine divisions Avere proposed, a number wholly unworkable on any extended scale, and undesirable for so small a county. The Victoria County History, passing over this propo.sal.of Mr. Hillhouse, takes the river-basins as its starting- point, and makes the following divisions: — 1. Nene ; 2. East Ouse ; 3. West Ouse ; 4. Ivel ; 5. Cam ; 6. Ouzel ; 7. Lea. Of these basins the areas draining into the Nene and the Cam are so small that for practical purposes they may be merged with their neigh- bours, Nene with West Ouse, and Cam with Ivel. This leaves five divisions, possibly in the estimation of some a number still too large. The records subjoined all fall under Mr. Hillhouse's Southern and under Mr. Druce's Ivel Division. Some parts of the Ivel Basin are more easily accessible from Hitchin than from either Luton or Bedford. Tlie Rev. Chas. Abbot in his Flora Bedfordiensis (1798) mentions foi- this disti-ict a number of plants in the neighbourhood of Potton whieii recent search has failed to re-discover — at least, no NOTES ON BEDFOBDSHIEE PLANTS 307 recent record of any of them appears to exist, although it is possible that some are still to be found. Abbot's list for the Potton neigh- bourhood includes : — fDianthus deltoides L. Mont ia font ana L. Hypericum Inimi- fusum L. ; H.pulcJirum L. ; S. elodeslt. Qeranium sanguineum L. Trifolium ochroleucon Huds. ; T. scahriun L. Galium uligino^um L. Solidago virgaurea L. Jasione montana L. fVaccinium Oxy- coccos L. i Erica Tetralix L. Hottonia palustris L. Vinca minor L. ^TJtricularia minor L. flfalaxis paludosa Sw. (as Ophrys paludosa). Juncus hulhosns L. fUJiyncJiospora alba Yahl. (as Schoenus albus). Carex divulsa Stokes ; C. leporina L. C. ros- tra ta Stokes. Those marked f are noted by Mr. Saunders as probably extinct. Any confirmation of Abbot's observations in this district would be a welcome contribution to the Flora of the county. A few plants are noted as " common " by Abbot, which do not appear to be now common in the Ivel district : — Lathyrus silvestris, JPimpinella major^ Serratula tinctoria^ Cnicus eriophorus. The following plants are noted as *' rare " by Abbot : — Arahis Thaliana, Ilex Aqnifolium, ^^Trifolium hyhridum, Sium erectum, Linaria minor, *L. Cymbalaria, Almis rotundifolia. These may all be said now to have a much more extended distri- bution. Mr. R. Morse's record of Seseli Libanotis possibh^ adds another county for its distribution, and confirms Mr. Saunders's expectation that it might be found. Although not strictly relevant to the subject of the present paper, I may here say that in 1912 I brought home from Arbury Banks, Herts, a well-known station for Seseli, seed gathered from fine plants three to four feet high, and scattered, them on an isolated balk in the middle of arable land near Little Almshoe, St. Ippolyts, Herts. Until last year I had not visited the spot to see if this experiment in naturalization (some, I fear, will say an undesirable one) had succeeded; 1 found fifteen flourishing plants, tall like their ancestors, and very different from those of the sheep-depastured down on which Mr. Morse found them in Beds, where they have a hard struggle to exist at all. The following list was drawn up at the end of 1918 : so far as Beds efforts are concerned, the present year has been a blank to me botanically, as I have not had time to make any expeditions. The only exception was a fortnight in West Norfolk in July which I spent with a cousin at Wallington, near Downham Market. He kindly motored me about, and I spent my time over a number of small " fens " which lay within a distance of 15 miles on the west side of the county. They differ both from the deep fens of the great level, and from the broads, and are more properl}^ small bogs in depressions between slightly higher ground, in the drainage basins of ■the Wissey and the Nar. 1 spent my time chiefly over sedges, but partly also over the distribution of forms of Marsh Orchis. In two, Foulden Common and Marham Fen, O. incarnata was predominant. In Beechamwell Fen, Caldecote Fen, Oxborougli Fen, Shouldham, 308 THE JOURNAL OF BOTANY O. prcetermissa Druce prevailed. In most of the latter a few plants with spotted leaves occurred, though I could not appreciate any other difference to warrant the suggestion of hybridism with O. Fuchsii Druce. Actually I only found the latter in Shingham Fen with O. prcetermissa.

Examination of the male flower of IL glohosa Griseb. {Croton (jlohosiim Sw. Prodr. 100 & Fl. Ind. Occ. 1181) confirms the opinion of Bentham and Hooker (Gen. PI. iii. 32-1) that this genus Avhen better known would have to be united with Thwaites's genus Chceto- carpus. The male flower of M. glohosa has an irregularly 5-partite densely 2)uberulous calyx, and 6 to 7 stamens inserted at different levels on a central column which is j^i'olonged above into a rudimentary pistil. The anther-cells are attached separately to the connective which is produced slightly beyond. There is an inconspicuous 4-lobed disk below the stamens. As Bentham and Hooker suggest, there are two West Indian species, one Jamaican originally described b}'' Swartz {Croton glo- hosum), the other an undescribed Cuban species known only from a fruiting specimen collected by Wright (no. 1973). Examination of the material available has convinced us that the Cuban plant repre- sents a distinct species, as shown b}^ the following comparison : — Ch^tocaepus globosus, comb. nov.

Bot. ii. 1913, 374, from specimens collected in Jamaica by Mr. William Harris and Dr. N. L. Britton. The author remarks tliat it is " near Sehastiania,^^ but does not indicate how it differs from that genus. Dr. Millspaugh NOTES ON JAMAICA PLANTS 313 describes the calyx-lobes in both male and female flowers as " each subtended internally by a minute bract with a glandularly fringed margin." We do not understand this use of the term '* bi-act," and prefer to regard ihis inconspicuous glandular fringe of hairs as repre- senting a disk. This might be regarded as a distinction from Sebas- tiania ; other differences are : the distinct subequal calyx-segments, the leaves sometimes opposite or whorled, and the solitary male flower in the axil of each bract. The genus, however, appears to be more nearly allied to the Old World genus Excoecaria, and to differ from this, as conceived by Bentham and Hooker, merely in the indication of a disk, and the presence of a caruncle. The material available of two of the species is incomplete: of D.fasciculata \sq know only the female flower; of 2». alpina only male flowers. Dendrocousinsia Millsp. Flores dioici, apetali.

The Thirty-fourth Annual Report of the Watson Botanical Exchange Cluh for 1917-1918 contains as usual much interesting material contributed by our leading British botanists There are valuable notes on critical genera and species : Mr. Groves's on Banunculus (Batrachiti?n),^r. Mojle Rogers's and Mr. Riddelsdell's on Buhtcs, Major WoUey-Dod's on Rosa, Mr. Barton's on Sali- cornia,Sind Mr. Pugsley's on Orchis inaij be mentioned as examples of the former and Mr. Salmon's on Arahis hirsuta, Mr. Little's on Brunns insititia, Mr. Marshall's on Byrus By raster, Mr. White's on Brunella laciniata, and Messrs. Little and Jackson's on Alnus r/lutinosa of the latter. Space will not allow us to quote these at length, but a few points ma}^ be noted. Mr. Groves makes useful suggestions : thus of Banunculus fluitans var. camhricuSy sent by Mr. Griffiths from the original Anglesey locality, he writes : " This curious plant has always been a puzzle, and it would be of great interest to ascertain if its peculiarities are due to ecological factors by cultivating it under different conditions, especially in running water. If the Batrachian Banunculi could be grown on an extensive scale I believe many of our difficulties in connexion with this group of plants would be solved." GormwQwim^ o\\ B. peltatus \M\fori- hundus, sent by Mr. White from W. Glos., he says: ''The peltatus- like form with shorter peduncles, which I understand b}' the name. A beautiful specimen, showing what can be done by careful floating out, in marked contrast to the draggled apologies for specimens one so often has to examine. There is no group of plants that better repay care than the aquatic Baminculi. It seems to me that it is worth while in the case of these and other water plants to float them out ; the trouble is not great, especially when one is dr^^ing a number, and the results are far more satisfactor}^ than if the plants are merely spi-ead out as in the case of land plants." On a plant from West Hoathley, Sussex, he comments: " A weak state of B. peltatus with unusually small flowers, or a hybrid with that species as a parent. The aquatic Banunculi hybridise freely, and, whenever specimens are WATSOX BOTAX'ICAL EXCHAXGE CLUE EEl'OET 315 . ]net with having weak peduncles ascending after flowering and pro- ducing few or no carpels, the other members of the group should be looked for in the neighbourhood to account for then- parentage." Such notes as these are very helpful, as coming from one whose admirable si^ecimens, prepared bj " floating-out," are illustrations of the process advocated. It may be noted here that the greater part of Mr. Groves's herbarium was presented recently to the National Herbarium, forming a welcome addition to the British Collection there. The Rev. W. Moyle Rogers contributes among other notes, a description of a new variety {Ritbus thyrsoideus Wimm. var. viridescens Rogers MS.) from N. Devon and W. Cornwall — the former collected as long ago as 1882 by himself and Mr. Archer Briggs, "The closeness of the connexion with type seems to be established especially by the combination of the strong deeply-furrowed glabrous stem with the comparatively short curved prickles and show}'" flowers of the panicle. It is, however, considerabl}'' unlike in habit and coloration, besides having leaflets narrower and soon bare beneath, vdt\\ panicle (when fully developed) considerably branched and pm'plish petals. From B. rusticmius, towards which it takes a step from type, it may be readily distinguished by its epruinose stem, its more compressed prickles and longer stamens ; and from my B. Sriggsicoius, which at first sight it recalls, by its sulcate stem and short curved panicle-prickles, as Avell as by its different leaves, greyer sepals and purplish petals." Of another of his varieties {JR. mucronaUis Blox. var. nudicaulis) Mr. Rogers writes : — "Though it is locally abundant in S.W. England, extending northwards to Swallowcliff (S. Wilts) and eastwards to Marvel Copse, near Newport (I. Wight), the distribution of this bramble seems remarkably limited, and I have not found it in Sussex, Somerset, Devon or Cornwall. Probably enough it occurs in all four counties. In Dorset and S. Hants it is frequent and constant, to the apparent exclusion of typical R. mucronaius Blox., from which it seems to keep distinct," In his introductory notes Mr. George Goode, the editor of the Report, thus refers to Mr. Rogers's withdrawal from the post of referee : — ** The Rev. W. Moyle Rogers has for so many years given us the benefit of his unique knowledge of the Biihi, in furnish- ing us with criticisms on the specimens sent in, that members will hear with the deepest regret that on account of increasing infirmity he has at last felt compelled to resign his position of referee. We are happy to say that the Rev. H. J. Riddelsdell, who has lately assisted Mr. Rogers, has kindly promised to examine and — where necessary — criticise all specimens of that difficult genus." A form of Rosa j)omiferay sent by the Rev. H. E. Fox, under the name R. cinnamomeay from " Undercliff, Kingsdown, Kent, appa- rently indigenous " is thus commented upon by Mr. W. Barclay : — "This is not R. cinnamomea L. It is a variation of R. iwmifera Herm., and as it has a certain number of subfoliar glands it might be considered as R. pomifera Herm., f. recovdita Christ (Rosen der Schwe?'z) = R. recondlfa Puget in Deseglise, Revis. sect. Toment. 46." Mr. White has an interesting note on Pyrus Pyraster var. z 2 316 THE JOURNAL OF BOTANY Deseglisei Eouy & Camus (P. cor data Desegl. non Desv.) from W. Gloucestershire — a tree which Mr. Marshall thinks is '* probably a distinct species ; it is quite different from P. cordata in fruit- character, and the leaves are more parallel-sided." Mr. White writes : "I take this to be the aborignial wild pear of the country, which I have only once before seen — in the Wye valley — and then it had not flowered. The largest of the three trees found near Range- worthy, from w^hich these specimens were taken, has a girth of over four feet, and is about forty feet high, with a spread of thirty feet. Its age probably dates from a period prior to the enclosure of the district in which it stands. In characters it agrees well with those of Deseglisei so far as given by Kouy and Camus, the fruit being globular, about the size of a large cherry (diam. 20-25 mm.), on long, erect-patent stalks. Obviously it is a very different plant from the P. cordata Desv. (named Briggsii by Syme) of which Mr. Briggs sent me a specimen from Plymouth in 1881. That has tiny pyrif orm fruit, attenuate at the base, * au plus de la grosseur d'une petite noisette ' (Eouy), and is well described by Boreau (Fl. du Centre), where I find no mention of the form under notice. Kouy and Camus hold, however, that Boreau's description covers several of their varieties. P. Deseglisei appears to be on record only from Cher in Central France." Mr. Marshall has notes on Saxifrages, including one on a new variety, which we transcribe : " aS'. liypnoides L., n. var. {rohusta ined.). Root from West Ireland, on limestone (R. LI. Praeger; received through Mr. E. W. Hunnybun) ; probably from Black Head, Co. Clare, v.c. 9, as I have a wild specimen, gathered there, which is clearly the same thing. Cult, garden. West Monkton, May 29, 1916, and May 31, 1917. Much stronger than the typical plant from Cheddar, grown under the same conditions. Axillary buds either absent or rudimentary. Stems stouter, stiff er, as are the lower cauline leaves. Flowers mostly larger." Specimens of Prunella laciniata L. collected by Mr. H. S. Thompson in a " rough pasture above Cheddon, N. Somerset, after a horde had apparently cropped many of the plants," are noted by the collector as "very variable in form of leaf and colour of flowers, evidently hybridising with P. vulgaris. The pale yellow floweis predominate, but some were pale bluish-purple, and a few had the upper lip pale purple and the lower lip pale yellow." On this Mr. White notes : — " The specimens on Mr. Thompson's sheets that vary in flower-colouring to tints of bluish-purple have in general sub- entire leaves, a combination suggestive of hybridity with P. vtdgaris. Such variations are mentioned in Fl. Brist., p. 478, and the idea that they are hybrids is there rejected for reasons given. Still, at my request, Mr. Bucknall has carefully dissected the flowers of these recent examples, and flnds that my previous conclusion is confirmed by microscope. On comparing stamens and calyces with those of typical laciniata no marked deviation can be recognised, the subu- late prolongation of the longer filaments and the calyx-teeth ciliation being practically identical .... As stated by the collector, the bulk of his contribution had been damaged by grazing, and so could not WATSON BOTANICAL EXCHANGE CLUB REPORT 317 satisfactorily represent this rare Labiate in any herbarium. Surely it would have been wiser, in view of the plant's scarcity, to have allowed such roots to remain undisturbed until they produced acceptable specimens later on." Mr. Marshall sends from his garden at West Monkton an unnamed Betula, with the following note : — '* Root from boggy, peaty ground, at about 2800 feet, descending from the Lochnagar tableland towards the Dhu Loch, S. Aberdeen, v.c. 92, July 1906. In the wild state this was a very small shrub, only a few inches high, with hairy leaves, strongly suggesting a cross between JB. nana and B. puhescens (I have never found the latter so high up). It has now grown into a good-sized bush, nearly six feet in height, but has never produced catkins. The leaf -outline has become much less crenate, and it mio-ht well pass for B. puhescens, var. microphylla ; but I still think that it may be a per-puhescens form of X B. alpestris Fr." The notes on Orchis relate to specimens collected at Mildenhall, W. Suffolk, by Mr. W. C. Barton, who writes : '* All [are] from one marshy field, where, in addition to those now sent, O. Fuchsii Druce {inaculata auctt.) occurred. The plants were sorted fresh, when the characters were easily distinguished. All forms varied much in size and in width of leaf (a character which I believe to be of no dia- gnostic value), and it is noticeable that all were gathered on the same day." They include a form of O. incarnata, which, according to Mr. Pugsley, " seems to show a somewhat greater foliar development and slightly broader lip than obtains in the extreme form of O. incar- nata occurring in the Scotch Highlands, the flowers of which, in my experience, may be either purple or salmon-pink in colour in different localities" : a plant named by Mr. Barton, who is "convinced it is a good species," O. prcetermissa Druce, of which Mr. Pugsle}^ says : '* This appears to be the plant which I understand to be O. prcster- missa Druce, and if so it is, I believe, the common marsh Orchis of the south of England, and the only form I have seen in Surre3^ Though its flowers are usually purple, they are occasionally flesh- coloured, and there were formerly a few plants with these pale flowers among the common purple-flowered form on Wimbledon Common": and a hybrid — O. Fuchsii X prcetermissa — the leaves of which " when fresh were distinctly spotted," on which Mr. Pugsley writes : — " If the leaves of this were spotted, and the plant was growing with the reputed parents, the identification is probably'- correct. The spur, however, simulates that of 0. latifolia, and it seems possible that the plant belongs to a form with narrow, spotted leaves, occurring in the south of England, which has been referred to that species, but which may really be the above-mentioned hybrid. But in the example sent I can see no traces of the dark variegation of the lip which characterises most, if not all, the forms of O. lati- foliar Mr. C. E. Salmon has the following note on Alopecurus geni- culatus Xpratensis=A. hyhridus Wimm. : — " This grass attracted the attention of Mr. L. B. Hall and myself when botanizing along the side of one of the numerous dykes of Amberley Wild Brooks. It was growing in plenty in close proximity to A. geniculatus, and formed 318 THE JOUR:ffAL OF BOTANY handsome clumps with its brilliantly glaucous sheaths and yellow anthers. The spikes were larger and the awns longer than in geni- culatvs, and the plants were taller and more robust, althougli decidedly geniculate near the base. The glumes and pales reminded one more of j^rafensis, but the ligule was long, as in geniculatiis. A. 2>rafensis grew not very far away in compai-atively dry ground, and it was noticeable that the hybrid preferred spots at the tops of the dyke banks, and did not choose, as is often the case with genicii- lafus, to have its roots in the water. These Araberley examples seem to agi-ee well wnth Messrs. Bromwich & Jackson's Warwickshire plant (B.E.C. Eep. 1900, 650) and the Rev. H. P. Reader's speci- mens of the hvbrid from Staffordshire (Watson B.E.C. Rep., 1900— 1, :M.). Mr. A. B. Jackson (Journ. Bot. 1901, 232) has also called attention to tlie remarkably glaucous sheath — a character which first caused us to take special notice of the plant." Mr. Groves notes on a plant sent from Nailsea Moor, N. Somerset, as " Chara vulgaris L., small form, ? var. crassicaulis " : "A form Avith broad secondary cortical-cells, well-developed spine-cells, and Avith the posterior bract-cells developed. Nothing like so extreme a plant as the var, or subsp. crassicaulis, which has a thick stem and more definitely botuliform bract and spine-cells." The foregoing extracts, which will we think interest a wider circle than that afforded by the Club, are but examples of the contents of the Report. We note Avith pleasure the absence of plants which owe their jjresence among us to mill-sweepings or rubbish- heaps and in most cases " have their day and cease to be " even before their names appear in print. J. W. H. TRAIL, M.D., F.R.S. James Wtlijam Heleists Teail, son of the Rev. Samuel Trail, M.D., LL.D., minister of Birsay and Harra}^ in Orkney, afterwards professor of systematic theology in Aberdeen UniYersit}^ and Helen, daughter of Dr. Hercules Scott, professor of moral philosophy, King's College, Aberdeen, was born at Birsa}'' on 4 March, 1851. Educated in the first instance at home, he was sent in due course to the Grammar School, Old Aberdeen, then famous for its classical training. From school Trail entered, in 1866, the arts faculty of the University of Aberdeen. Dr. Trail had formed a high estimate of the lad's capacit}^ and entei-tained the hope that his son, like himself, might become a churchman. But at school Trail hardly fulfilled his father's expecta- tions. Always a diligent pupil he accomplished the tasks he Avas set, but shoAA^ed no promise of attaining distinction as a classical scholar. Perhaps this was largely due to Trail's addiction to natural histor}^ pursuits, Avhich was so pronounced as to earn from his school-mates a kindly if playful agnomen which had not yet fallen out of use Avhen he became an undergraduate. His companions at school had, in fact, as sometimes hajjpens, formed a sounder judgment Avith regard to his mental powers lluin had his teachers. .TAMES WILLIAM HELEJfUS TEAIL 819 As an arts student Trail's academic career at first much resembled that of his school-days. For the humanities, in Avhich he had so lono- been assiduously drilled, Trail had lost any liking he may ever have possessed. Mathematical work, though it hardly cost him an effort, never awakened any vivid interest. Even in philosophy, of which he showed, later in life, so firm a grasp, his youthful interest in natural processes other than mental was too engrossing to permit academic distinction. When, in 1867, Dr. Trail took up the duties of his chair and was once more in personal contact with his son, the situation induced grave paternal misgiving and provoked no little paternal impatience. That Trail had not taken the position which his father had felt justified in expecting, was attributed to the consumption of valuable time which Trail's devotion to natural history involved. In spite of discouragement, the harder to combat because its intention was kindly, Trail remained devoted to natural history. During the magistrand pliase of his arts course his firmness of purpose was fullv rewarded. Now he was able to attend the natural science classes and to show, by his appearance in these, that he was in reality one of the most distinguished students of his year. When, in 1870, Trail graduated in arts with honours in natural science he passed on to the faculty of medicine, not from any desire to become a surgeon or a physician, but with the object of obtainino- a further training in science. In the new faculty he maintained the brilliant position he had acquired in natural history, but when, in 1873, it was in his power to accompany, as botanist, an exploring expedition to the Amazon region, he laid aside his medical studies without hesitation rather than miss such an opportunity of first-hand acquaintance with a tropical fauna and flora. When he returned in 1875, Trail resumed his medical studies and graduated as M.B. with highest academical honours in the following j^ear. Ti-ail had already commenced the publication of observations re- corded by himself at the beginning of his medical course and before he left for Brazil had made his earliest contributions to the study of galls, a subject as to which he acquired in time a European reputation. On his return from the Amazon journey he at once began to work out his results ; his earliest contributions, relating to the palms, appeared in the Journal of Botany during 1876-7. The abilitv he had displayed in securing his specimens, and the thoroughness of his descriptive work, attracted immediate attention and led to his appoint- ment, towards the end of 1876, as government botanist in British Guiana ; but before the date fixed for his departure had arrived Professor Dickie, then Professor of Botan}^ at Aberdeen, was com- pelled to relinquish his chair owing to failing health. Trail was appointed by the Crown to the vacant post and took up his duties, shortly after his twenty-sixth birthday, at the commencement of the summer session of 1877. Having fulfilled these duties with tlie utmost efficiency for forty-two sessions he has now died, almost in harness, after a brief illness, which involved surgical treatment, in a nursing home in Aberdeen, on 18 September, 1919. Without being a fluent speaker, Trail was a clear and convincing teacher. The precision with which his statements were made and the 320 THE JOURNAL OF BOTANY care with which his words were chosen made liis lectures models as a means of instruction. The skilfulness of his method and the judg- ment shown in selecting his material rendered his practical classes equally perfect as a means of education. As the leader of a field- excursion Trail can have had few equals and certainly no superior. At the outset of his teaching career the resources of his department, chiefly owing to lack of accommodation, left much to be desired. With untiring energ}^ he set to w^ork to remedy defects, and he has left for his successor a botanical department fully equipped with an adequate teaching museum, good laboratories, and an excellent botanical garden. On his return from Brazil in 1875 Tmil was elected a Fellow of the Linnean Society-. In 1879 he obtained the degree of M.D. in his own University. In 1886 he became president, on its foundation, of the Aberdeen Working Men's Natural History Societ}'-, a body in whose doings and welfare he took the keenest interest, presiding over its meetings and often leading its excursions. In 1898 he was elected a Fellow of the Royal Society. In 1910 he presided over the botanical section of the British Association at its eightieth meeting. The capacity for business displayed in the organisation of his owm department led to his help being much in demand in connection wdth University affairs. He made himself an efficient officer of the Uni- versity battery, which owed its existence very largely to his efforts. When the territorial organisation displaced the volunteer system he became an invaluable member of the officers' training corps committee. From 1891 onwards he served as cumtorof the University libmryand chairman of the library committee, while from 1892 onwards he served as dean of the newly created faculty of science. He played a prominent part in the establishment of a lectureship on forestry, and in the development of an agricultuml department. Authorities external to the University were equally eager to secure his aid, and where the object was the advancement of education, more especially scientific education, this aid was readih' given. This involved accept- ance of the governorship of various educational trusts and the chair- manship of more than one education committee. To the furtherance of objects in which Trail was interested he devoted means as well as time. In memory of his mother he endowed a fund intended to benefit students in any faculty of the University who may have given proof of ability in the study of natural science. After having served as curator of the library for a quarter of a century, he established another fund whose income is available, ' in supplement of ' grants from University revenues, for the addition to the library of works relating to natuml science. In the Linnean Society, whose welfare and renown he always had much at heart, he founded an * award and medal ' in recognition of special research. These recorded acts of generosity, however, represent but a small portion of Trail's thoughtful and unobtrusive benevolence, just as his published notes and papers, numerous and important though they be, represent but an infinitesimal part of the vast store of knowledge acquired by him as the result of exact and patient observation and investitifation. The width of rancre of his information was as astonish- JAMES -WILLIAM HELEXUS THATL 321 ing as its exactitude. That knowledge was alwaj'-s freely at the disposal of anyone who might seek his assistance, and those who have profited most by his aid are also those who most lament that Trail's high sense of public duty should have involved such inroads on his scanty leisure as to prevent the permanent record of much that he knew which it would benefit others to know. It was not, however, his knowledge alone that made any interven- tion by Trail in discussion so valuable and gave such a charm to intercourse with him. The regard and esteem in which he was held, the authority with which he spoke, and the attention with which he was heard, were due to his sincerity and kindliness as much as to his knowledge. In Tmil those who knew him deplore the loss of the wise counsellor and the generous friend even more than that of the eminent natural historian. D. Pkain. BIBLIOGRAPHICAL NOTES. LXXVII. John Ellis's Directions for Collectors. A damaged copy of a pamphlet, printed (but apparently not published) in 1771 has lately been presented to the Department of Botany. It is entitled " Directions for bringing over Seeds and Plants from the East-Indies and other distant Countries in a State of Vegetation," and is anonymous. It proves to be a reissue of the first portion of the pamphlet published in 1770 (with the same title) by John Ellis (c. 1710-76) : to the original, however, is added as a second part the account of Dioncea that Ellis sent to- Linnaeus, on which the description of the genus (Linn. Mant. ii. 238) was based — it may be noted in passing that the plate accompanying the letter was taken from a plant that flowered in [Ellis's] chambers in August 1768 (see letter fi-om Ellis in Linnaeus's Correspondence., ii. 73). The reissue does not entirely correspond with the original : the first and last paragraphs of the latter are omitted, as well as the long footnote (pp. 17, 18), and there are slight deviations in the text. It contains an additional chapter, with plate, on *' The Method of catching and preserving Insects for Collections." The " Directions " is referred to by Lettsom (1744-1815) in \i\% Natural History of the Tea-Tree (1772 — I have only seen the "new edition ''' of 1799) — in which Ellis's plate illustrating "Boxes for conveying Plants by Sea "" is reproduced, though without acknowledgement. It would appear from Lettsom's note (p. 54) that Ellis had contemplated the publi- cation of a second edition of his " Directions,'^ but this does not seem to have appeared. The Naturalisf s and Traveller'' s Companion, to> which the note makes reference, although published anonymously (1722) is Lettsom's own work. James Britten, 322 THE JOUBXAL OF BOTANY SHORT NOTES. New CoL'NTr Records for ARarLE. In the course of a visit in September to the district at the nortli end of Loch Awe, I came across the following species which are not recorded for 98 Ai'gyle in either Watson's Topographical Botany or Mr. Arthur Bennett's Supplement, and of which Mr. Bennett himself tells me that he has no subsequent record. Hypericum pulchrum L. Frequent, and ascending some way up the hill-sides. — Frunus avium L. Tay- chreggan. — Centunculus minimus L. Glen Nant. — Tanacetum vul- gare L. ? G-arden escape. — Myrrhis odorata Scop. Portsonachan. h Garden escape. — ^'Mentha sativa'^ (aggr.). Kilchrenan. — Poly- gonum Hydropiper L. Frequent about Kilchi-enan. — Potamogeton pf^rfoliatus L. Loch Awe. Three other plants {Cardamine Jiexuosa With., Juncus tenuis Willd., and Equisetum sylvaticum L.) were also found which do not appear in either of the above works, but %vhich Mr, Bennett informs me have been recorded elsewhere for the county. Juncus tenuis was growing in good quantity by the road- side in a wild glen a long way from any habitation. — L. V. Lester Garland. Carex mOxVTana L. (p. 27-i). Since this was gathered by Mr. written in May, 1842, in a heathy field, between Eridge and Tunbridge Wells, whence I have a specimen, its habitats have been greath^ increased, and it is now on record for 17 counties. Of these, seven are recorded in Top. Botan}^ three in the Supplement, — these with Brecon (Bot. Ex. Club Report for 1883) make the eleven in the London Catalogue, ed. 10. Since then it is on record for : 2. Corn- wall E., Curnow sp. ; 9. Dorset, E. F. Linton sp. ; 22. Berks, Rept. Bot. Ex. Club, 1918, 102; 24 Bucks, Miss Armitage, Z. c." ; 41. Glamorgan, Miss Vachell sp. ; o7. Derby, Waterfall sp. Mr. Thompson's interesting notice speaks of its early llowering ; in culti- vation it flowers in Ajjril, before ericetorum, pi'cecoXf qy pilulifera. — Arthur Bennett. Isoetes Hystrix Durieu in Cornwall. On June 19th last I gathered this plant, hitherto unknown for England, at the Lizard, growing with Trifolium strictum and T. Bocconii. I saw one specimen only, but am convinced it is probabl}^ to be found in many similar situations. The specimen is small and the pkint would be very ditiicult to find unless especialh^ looked for, which I believe botanists have not been in the habit of doing in this particular neighbourhood, — Fred. Robinson. Vaccinium intermedium Ruthe, I am quoted (p, 285) as having found this hybrid on Whitley Common. The site was on Whitmore Common — about a mile N.E, of Whitmore Station (L. & N,W. Ry.), and within two miles of Maer Woods — the date being Aug, 23rd of this j'-ear. The plants, growing with the parents and Empetrum nigrum, were in full flower and unusually fragrant, in scent resembling hawthorn or meadow-sweet. — W. Balfour GOURLAV.

Norfolk, specimens answer to the above, and are a greater development of the var. Hookeri Syme. — Aethur Bennett. Elatixe Hydeopiper in Worcestershire. I was fortunate enough to find this plant growing in great abundance at Westwood Pool near Droitwich, on the 4th August, 1919. Irvine in the Phytologisf, ii. 401 (1857-8) records it as having been found by him "in a mill-pond near Churchill Railway Station, Kidderminster, Worcestershire." — Caeleton Rea. REVIEWS. Fossil JBlanis, Vol. IT., GlnAyoales, Coniferales, and Gnefnles. By Prof. A. C. Seward. Cambridge University Press. 1919. [Pp. xvi + 544 with 190 illustrations. Price £l'ls. Od. net.] With the volume before us the author brings to a conclusion this text-book of Fossil Plants, of which the first volume appeared twenty- one years ago. Probably no one Avho has not actually undertaken a work of a similar character can gauge the magnitude of the task involved. The mere collation of the extensive and widely diffused literature of the subject is in itself no mean feat, and the compre- hensive bibliographies are not the least useful part of a work that occupies an assured position amongst the standard text-books of Palseobotanical literature. The first seventy-five pages deal with the Ginkgoales, a summary of the more important features of Ginkgo hiloha, the "living fossil " serving as an introduction to the extinct representatives. With reference to these latter Prof. Seward expresses the opinion that none of the fossil wood referred to Ginkgo is above suspicion. For the leaves belonging to this and allied forms the author proposes a new genus, Ginkgoites^ though the distinction from Baiera, which typically has narrower and more numerous segments, is admittedly arbitrary. The genera Ginkgodium, Czeckanowskia, Feildenia, Plicenicopsis, and DesmicopJiyllnm are regarded as possible representatives of the group, but the other genera usually placed here, viz. Ginkgopsis, Nepliropsis, Psygmophylhim, Rhipidopsis, Saportcea, Dicrano- phylhim, Tricliopitys, and Sewardia., are considered to have been assigned to the Ginkgoales on totally inadequate grounds. The account of the recent Conifers is not only admirable as supplying the proper perspective for the Palseobotanist, but also as furnishing a much-needed and judicious summary of the extensive literature on the anatomy of the family which will be welcomed by all classes of students. The author subdivides these into nine tribes, of which three, viz. the Sequoiinese, the Sciadopitinese, and the Phyllo- cladinese, are each represented by but a single genus. The remaining tribes are the AraucarinejE, held to be the most pnmitive, the Cupres- sinese, the Callitrineae (including Callitris, ActinostroMis, and Widdringfonia), the Abictinese, the Podocarpinese, and the Taxinea?. 324 T1I1<: .lOUllNAL OF UOIANY Following Saxton, Tetraclinis is assigned to the Cupressinese, whilst Taiiuania, Fohienia^ and Atlirotaxis are tentatively placed in the same tribe. After a considered statement of the pitfalls besetting the path of the palaeobotanist studying coniferous material, the fossil woods belonging to the Coniferales are classified under fifteen genera, of which one, Mesemhrioxylon, is established for the inclusion of the three genera Podocarpoxylon^ Fhyllocladoxylon, and Taraphyllo- cladoxylon. New species are described in the genei'a Dadoxylon^ Cupressiiioxylon and Protopiceoxylon. Cupressinocladiis is created for the reception, of vegetative shoots agreeing with recent Cupres- sinea? and Pityites for fertile specimens of Abietineous fossils whose more definite systematic position is unknown. Two species are placed in the latter, of which one is new. A chapter is devoted to a number of Coniferalean genera of uncertain position and also to Podozamites and Nageiopsis whose aflinity is open to doubt. After treating briefly of the recent G-netales the author points out the lack of trustworthy'' records of Gnetaleiin plants as fossils, and suggests that a careful stud}^ of the older supposed Dicotyle- donous plants might reveal members of this group. The entire omission of the Angiosperms will be regretted by all,but it is ex- plained that a critical examination of the actual specimens, with the co-operation of a trained systematist, is needed before the value of the available material can be adequately estimated. There are two indexes whose positions might preferably have been reversed — the first to the fossil genera enumerated throughout the work, and the second a special index to the present volume. Like its predecessors, the present volume is fully illustrated with numerous photographs and drawings of recent and fossil species ; the typography maintains the high standard which we are accustomed to look for in the productions of the Cambridge University Press. Though Prof. Seward expresses, in the preface, his relief that this text-book has been brought to a conclusion, the feeling must be accompanied by satisfaction at the completion of a task which will earn the gratitude of all English-speaking Palseobotanists. E. J. S. Lowson's Text-hook of Botany (Lidian Edition). Revised and adapted by Birbal Sahni, M.A., M.Sc, and M. Willis, with a Preface by J. C. Willis, M.A., D.Sc. London : W. B. CHve. Pp. xii, 610. Whex the first Indian edition of this text-book came under review five years ago (Journ. Eot. 1914, p. 343), attention was dmwn to Dr. Willis's preface — which re-appears in the present issue — remarking on the Oriental tendency to learn by rote. Recognizing this tendency, we are more than ever convinced that the very detailed completeness of Lowson's work unfits it for the Indian student, if real teaching and not merely success in the examination-room be the end in view. This is not to say that the adaptation of the work for India has been badly done : on the contrary, both Mrs. Willis and LOWSON S TEXT-BOOK OF BOTAXY 325 the present editor, Mr. Sahni, who is Lecturer in the University of Benares, have made the best of it. The chief alterations introduced by the latter are the re-arrangement of the Orders according to Engler's system and a re-casting of the descriptions of the stelar systems in the Pteridophyta. There are defects which are inevitable in an adaptation of a work to another purpose, and which give a greater force of appeal to a work written originally ad hoc. Our objections are i-ather to Lowson's original work than to that of his editors. If this is meant for a first book, its beginning, with formal definitions and subdivisions, with pure morphology and his- tology, is certainly not calculated to attract the young student. Again, the sequence of the chapters in Part iii appears to us hope- lessly illogical. Following the anatomy and taxonomy of angio- sperms we have a chapter on Pteridophyta ; then one on Gymnosperms ; a third on Homologies in Angiosperms ; a fourth on Relationship between Vascular Cryptogam and Flowering Plant, followed by one on Ecology! A Manual of Elementary Botany for India, by Rai Bahadir K. Ranga Achari, published at Madras in 1916, seems to proceed on a sounder educational method. It begins heuristically by taking two excellent and well-known Indian types, Trihulus terrestris L. and Gynandropsis pentapTiylla L. ; introduces the principles of physiology gradually j9«rr/ ^rtss2^ with the anatomy ; and deals only with promi- nent Orders of Indian angiosperms, without attempting to force upon the beginner a bewilderingly concise summary of the complex variety of the Cryptogamia. Considering the immense area and varied flora of India, it is, perhaps, better that text-book writers should not attempt to provide one book for the whole empire. Writing in Madras, Rai Achari gives Tamil and Telugu equivalents in his Index, while Mrs. Willis and Mr. Sahni give preference to Hindi; stani. In his " Note on Second Edition " the latter dwells on the European facies of the flora of the North-west Himalaya : it would have been instructive to have given instead a brief sketch of the various florulas of which the whole Indian flora is made up — a summary, in fact, of the admirable summary drawn up by Sir Joseph Hooker for the Imperial Gazetteer of India. G. S. BOULGEE. Gossypium in JPre-Linnean Literature. By H. J. Denham, M.A. Botanical Memoirs No. 2. 8vo, pp. 24. Price 2s. net. Oxford University Press. In this interesting pamphlet the author gives a very thorough account of what is known of the early history of the Cotton plant in cultivation. The scheduled list of pre-Linnsean authorities, so far confined to early and little-known writers, includes sixty authors, from Herodotus, Theophrastus and early voyagers, to Fuchsius and Ximenes, Caspar Bauhin, and Linnaeus. It affords an extremely interesting study of the manner in which the story of the races of a plant of greatest economic importance in different parts of the world 32G THR JOURNAL OF BOTAIfY lias been gradually collected and ]n\t together by European herbalists and systeraatists of the past, to be crystallized with difficulty in more recent literature. The cultivated strains may of course be largely conventional, of unkno^vn origin and of wholl}'' unknown antiquity, thus rendering the isolation of the elementary species a labour of the future, before selection and hybridization by modern methods can be put on a satisfactory footing. It is interesting to note the reproduc- tions of the oldest recognizable figures of the plants, as the ' Xjdon ' {G. Iierhaceum) of Fuchsius (1542) and Matthiolus (1568), for com- parison with the * Gotnemsegiar ' {G. arhoreum) of Alpinus (1592), and the * Ychcaxihuitl ' {G. mexicaiium) of Ximenes (1651), as illustrating the earliest-known strains ; as also the early significance of the last as a textile in the New World, as compared with the inde- pendent evolution of the Old- World cottons in India, and the later extension of G. herlaceum to Europe and Africa. The economic species of Cotton are essentially tro])ical, and it is difficult to get an idea of them at their best in this country, but the future of Gossypium in colonial dependencies is assured, and everything bearing on the organization of so highly specialized a herbaceous type, which resj^onds so readily to changes in the environ- ment, has a significance beyond present estimation in the future control of tropical agriculture. The arrangement of the bibliographical list leaves something to be desired. It begins with " Herodotus, Historia. Ed. Kawlinson. Murray, 1858 " ; it would have been better, we think, to have given the date of the original, while indicating the edition used. Mr. Henry Lee's little volume on The Vegetnble Lamb of Tartary : a Ciiriotis Fable of the Cotton Plant (London, 1887) seems to have escaped Mr. Denham's notice and should be referred to should his essay reach another edition. BOOK-NOTES, NEWS, etc. Some months ago a committee, of which Sir David Prain was chairman, was appointed to consider what steps could be taken to increase the usefulness of the Royal Botanic Society, which was in- corporated in 1839 and holds a lease of eighteen acres in Kegent's Park. From the published report we learn that the committee have formed the opinion that the Society could be made more useful both from the scientific and educational point of view by the establisliinent of: — (1) A school of economic botan}-, at which a knowledge of tlie economic plants and their products, including those of tropical regions, might be obtained; (2) an institute which might be made a centre for research, more especiall}^ in plant physiology, where the living plant is essential; (3) a centre for teaching in horticulture, the students of Avhich could receive their necessary training in ])ure science at existing London colleges ; (4) courses in school gardening, at times suitable for teachers in elementary, continuation, and otlier schools. In addition, the committee consider that the Gardens might BOOK-NOTES, NEWS, ETC. 327 extend their present utility as a centre from which colleges and botany schools could be supplied with material for teachmg and research, and in which students could make use of the existing facilities for the study of systematic botany. A NEW botanical magazine, The Journal of Indian Botany, edited by Mr. P. F. Fyson, of Presidency College, Madi-as, is bemg published by the Methodist Publishing House of that city. The Journal " has been founded for the publication of original papers in Botany which would not naturally find a place in the existing Indian journals, for there is no other journal in India which could accept a paper on ecology, physiology, histology, or the cryptogams, except such as might be of agricultural interest." The first number (Sep- tember) contains the following papers : " Dimorphic Carpellate Flower oi Acalijpha inclica'' by L. A. Kenoj^er, with two plates; "The Myxophyceae of Lahore " by S. L. Ghose, with plate ; " On Alysi- carjous rugosus and its allies," by L. G. Sedgwick; a "Note on the Ecology of Spinifex squarrusns " by P. F. Fyson and M. Balasub- rahmanyam ; and a useful series of abstracts of current literature relating to Indian botany. The Kew Bulletin (no. 5) contains a very interesting account, by Mr. W. Dallimore, of the Falkland Islands, especially relating to their forestry, abstracted from the correspondence between Kew and the Governors of the islands, dating from 1842 ; it includes an account of the introduction of the Tussock Grass {Poa Jlahellata Hook, f.) into Britain. Hooker's specific name for the plant, published in Phil. Trans, clxviii. (1879) p. 22, footnote, doubtless stands, as the first description is that of Lamarck (Encycl. ii. pt. 2, 462) as Festuca jlahellata \ this part, according to Journ. Bot. 1906, 319 (which should be consulted when the dates of the 'Kncyclo'pedia are in ques- tion) was published in April, 1788. Forster's Boa ccBsintosa stands as a nomen nudum in his Brodromus, p. 89 (1786) ; he did not describe it until 1789 (as Jbactylis : Comm. Goett. ix. 22). There is no ground for the doubt expressed by Hooker (Z. c.) as to the identity of Forster's plant : Steudel, who calls it B. Forsteri ( Gra- viince, p. 260: 1854) cites Forster's name as a synonym without hesitation, and we have in the National Herbarium a specimen from Forster so named. In nos. 6-7 of the Bulletin Mr. W. B. Tun-ill summarizes the " Botanical Results of Swedish South American and Antarctic Expe- ditions," and there is an "abridged translation of the more important ]jarts" of Mr. W. E. Hart's history of the Botanic Gardens of Pamplemousses, Mauritius. In no. 8 Mr. Sprague has a monograpli of the Bignoniaceous genera Dolichandrone and Marhhamia, to which attention was called by Seemann (who named the genera) in the early volumes of this Journal (1863-70). Mr. W. Wilson, of Honolulu, has brought together in a pamphlet all that is known of Bavid Douglas at Hawaii (Thrum, Honolulu, price I dollar). It does not add materially to oiu- knowledge, but 328 THE JOURNAL OF BOTANY contains some interesting views of places associated with Douglas's journeys and a picture of the memorial tablet erected to his memory on the front wall of Kawaiahao Church, Honolulu. The friends of the late Clarence Bicknell (see Journ. Bot. 1918, 303) are anxious to place in Bordighera some memorial of his forty years' residence there. ** In addition to his keen scientific work in inany varied fields, he took the deepest interest in the welfare of the poor and was one of their best friends and most generous benefactors, and it is proposed that the memorial should take the form of a dis- pensary for the gratuitous treatment of the poor and an increased endowment of the Home for the aged. Many botanists who have visited Bordighera have benefited by Bicknell's knowledge and kind- ness, and it is thought that there may be some who would like to cooperate in the scheme" : contributions should be sent to P.

We note with pleasure the greatly improved appearance of the Transactions of the British Mycological Society for 1918 (Cam- bridge University Press, price 10s. 6f?.) for which we think our continued protests have been at least partly responsible. Among the contents may be noted the presidential address of Dr. David Paul, *' On the Earlier Study of Fungi in Britain " ; notes on some Sapro- phytic Fungi of Potatoes, by Dr. Pethybridge, with two plates ; notes on Coins Gardneri (1 plate) by Mr. Petch ; New British Fungi, by Miss Wakefield ; New or Rare Microfungi b}^ Miss A.

Linton has re-issued his Flora of Bournemouth, which appeared in 1900, with an appendix containing numerous additional localities and a list of Ruhi b^^ the Rev. W. Moyle Rogers, as well as one or two additional species, to which we think attention should have been called in the prefatory note. Of these the most interesting is Lobelia urens " on a heathy piece of woodland, to which I was conducted by the Rev. C. 0. S. Hatton, in Hinton, where we were both of opinion that it was a native station." Mr. Martin Nijhoff of the Hague announces the publication of the first volume of an Enumeratio Systematica Fungoritm by the late C. A. J. A. Oudemans (t 1906). In the preface, which has been distributed as a circular, the editor, Mr. J. W. Moll, gives an interesting account of the work and of the botanists who have con- tributed in its production. When completed it will consist of five volumes of about 1200 pages each : the price of each is £3. Dr. S. H. Vines is retiring from the Professorship of Botany at Oxford at the end of this j^ear. The attention of our readers is called to the advei*tisement of the volumes of the Journal which appears on p. 3 of the wrapper of this number. :V29 HISTOKICAL EEVIEW OF THE FLOIUDE.E.— II. By a. H. Chue€h, D.Sc. Taken at their simplest valuation as original autotrophic phyto- benthon of the sea, and removed from all academic prejudices with regard to an antithetic alternation of generations, which have obscured the discussion of the origin of the vegetation of the land ^ — the latter, so far as the Florideae are concerned, being considered as yet non-existent, — this remarkable race expresses an independent line of evolution in the sea from some ancestral stage of encysted plankton- flagellate, attaining somatic and reproductive specialization along its own lines, and meeting the problems of inevitable benthic wastage in its own wa}'^, as a race apart from other residual marine phyla ; and now narrowly circumscribed, but wholly intelligible by reference to other benthic phyla also found in the sea, which had to meet the same problems though with somewhat dilferent equipment. Haus- torial connections and even nuclear migrations, which play so con- spicuous a part in the nutrition of the carposporophyte, are but the extension of the secondary pit-connections and nuclear migration observed in somatic organization, though less obvious and more minute ~ — again rendered possible by the special nature of the soft gelatinous polysaccharides of the wall-membranes and the mechanism of the primary ' Floridean-pit.' Coenocytic decadence of the trophocyte-^ is paralleled by secondary coenocytic organization in the vegetative soma of distinct generic types ^. Deterioration of the unilocular sporangium, normally restricted to the production of one meiotic tetrad ^ to a mere monosporangium ^, may be traced in PhseophyccEe, though not becoming such a general feature " : while loss of phases in the life-cycle (asexual, as in Kemalion, Scinaia, Lemanea, or sexual, as in 'Rhodochorton, Rhodymenia 'palmata) is again but the familiar indication of the deterioration induced by inferior and limiting environment ^. The plants are no longer a group of mystery, but are readily intelligible in all their domestic relations, though presenting a wide range of variation in such processes, as also in somatic form and con- sti-uction. The geneml working-plan of the life-cycle of the vast majorit}' of the better-di:fferentiated types is based on a three-phase system ; involving, that is to say, three successive individuals, or pre- 1 Gf.

JOLENAL OF BOTAM-. VoL. 57. [DECEMliElt. lOlU.] 2 A 330 THE .TOUENAL OF BOTANY ferably generations, since the sexual phase itself is commonly represented by male and female persons ; two of the generations are asexual, and produce spores which express the output necessitated by the dispersal function, and the amount of wastage to be counter- balanced. The meaning of ' Alternation of Generations,' when viewed from the locus of the sea and not from the standpoint of transmigrant Land-Flora, is simple and illuminating. The assumption of a sessile benthic state of organism as an improvement on the older phase of suspended plankton, although wholly advantageous in mechanism of nutrition, and leading to the specialization of the efficient algal soma of marine phytobenthon, brings with it the necessity of regression to the active tlagellated condition for purposes of the ' sexual ' reproduction initiated and established in the ante- cedent plankton-state. Hence algal phyla produce flagellated zoid- gametes, some of which conjugate to give a sexually produced zygote ; others remaining * apogamoiis,'' if so far failures, may nevertheless ' germinate ' on attachment to a substratum to give a new individual. Such production of gametes fulfills two functions : — (1) that of sexual fusion as the contm nation of an older plankton-phenomenon ; (2) that of dispersal, a new phenomenon, first necessitated in the benthic state, as a biological function of henceforward supreme sig- nificance. As progressive differentiation of sexual mechanism leads through inevitable stages of heterogamy to oogamy and fertilization in siht, following the ultimate failure of the oosphere to be discharged in the open medium, different phyla of algae may attain different degrees of perfection in this respect. But while such fertilization in situ expresses the maximum economy in reducing the wastage of the sexual process, and the successful attachment of the zygote, it leaves the function of dispersal wholly unprovided for. Hence the fm-ther differentiation of special individuals devoted to this latter pm-pose, to be taken on by the ' unilocular sporangium ' as an adapted unilocular gametangium now desexed, becomes equally inevitable. All advanced phyla thus tend to differentiate two generations, as the ultimate response to the necessities of two great physiological functions ; one secures the sexual act and chances subsequent dispersal, the other secures dispersal and omits the sexual act. What was originally simple differentiation {Bictyota) becomes a more exact alternation as soon as fertilization in situ is established, since a sexual plant sessile and parasitic on a parent would be absurd ; and all phyla of advanced plant-organism present this specialization, apai't from any considera- tion of what may be the state of the nuclear organization, or of alternation of generations for the sake of academic considerations. The special point of interest of the Florideae is not so much that they should have attained fertilization in situ, a parasitic zygote and a * sporophyte generation ' producing asexual spores, but that they now present a succession of three generations, according to the scheme : — I. Gametophite. with sexual organs, and spermatogamic ferti- lization in situ : the parasitic zygote becoming a reduced HISTORICAL RETIEW OF THE FLORIDE^ 331 II. Caeposporophtte, bearing reduced unilocular monosporano-ia, dispersing diploid carpospores. The latter germinates to a' III. Tetrasporophyte, as a free autotrophic individual, also pro- ducing unilocular sporangia, but these giving rise to one tetrad of 4 spores, associated with meiotic mechanism and dispersing haploid tetraspores. Or, considering these general phenomena in further detail: — I. The sexual plants (gametophytes) have long attained to the extreme limit of sexual economy and efficiency as expressed by ferti- lization in situ ; in the progression to which the flagellated zoid (antherozoid) has been w^hoUy lost. The contents of the antheridium, reduced to the limiting expression of an immobile * spermatium ' discharged in its endochiton, fuse (spermatogamy) with a specialized hair-attachment process (trichogyne) of the oogonium (carpogonium). Preceding states of heterogamic progression ai-e superseded by post- sexual nutrition, and the gametes are expressed as mere nuclei (a con- dition otherwise attained by the highest Angiosperms only by very devious routes). The possibility of the initiation of such post-sexual nutrition of the zygote is now seen to depend on the mechanism of the primary pit-connection left open at the base of the young carpo- gonium, and hence follows legitimately as an opportunist utilization of a factor of ancestral organization. II. The parasitic zygote thus ' germinating ' in situ, and nourished by the parent, is necessarily asexual and devoted to the production of asexual s^Dores, since a sexual plant parasitic on a jDarental sexual organism would be in bad case; but such plants in catena, with fertilization in situ, would be an impossibility, as destroying the whole idea of the retention of the sexual process. Whether such .t second generation is diploid or haploid is purely immaterial (the former is as a matter of fact the rule, since there was no inducement afforded for meiosis at ' germination '), but they must produce freelv- shed spores. On the other hand, the extreme decadence of the attached parasitic generation, recognized as a mere tuft of gonimoblasts at the best, is expressed also in the deterioration of the unilocular sporan- gium (which should have been a tetrasporangium at one time, in the manner of Dictyotd) to the state of a monosporangium, in which the uninucleated contents are discharged in endochiton as carpospores; meiosis being omitted, or alternatively described as ' delayed.' Hence the second parasitic individual or generation may be conveniently termed the carposporophyte, prevailingh^, though by no means neces- sarily, diploid in its nuclear organization. III. The free carpospores, being dispei-sed, take the small chances of immediate germination on attachment to any available substratum, and grow to a free autotrophic soma, in all respects like the first autotrophic individual ; vegetating in exactly the same way, and carrying on the nuclear organization of the parent carposporophyte, to produce again unilocular sporangia, this time with fully nourished meiotic mechanism and production of the limiting tetrad of four tetraspores. The latter are in turn freely discharged to the external medium, as haploid immobile units. The third individual is tlius ;^82 THE JOUKNAIi OF JiUTANT conveniently indicated as the tetrasporopliyte, and is equally a distinct ' generation ' or ' phase ' in the life-C3^cle. Such haploid spores, on immediate ' germination,' give a haploid soma of normal free and autotrophic organization, which may he sexual and repeat the sequence. But there is no reason at all why, by omitting the sexual organs, it might not produce unilocular sporangia, which being haploid would not require a meiotic division ; and hence would not give a tetrad system, but 3'et ' spores ' of sorts for free dispersal. Many decadent Floridean genera are in this position, at the verge of latitudinal or vertical distribution ; as also in many cases so-called tetraspores are found freely on the sexual pla its K Special interest also attaches to cases in which the tetraspores are wanting, as indicating the failure to produce meiotic sporangia ; and the reducing-di vision has to be effected elsewhere. That the locus of such a process is again wholly subsidiary and secondary is shown by the details now available of cases in which the stages have been followed. Thus in Scinaia, according to Svedelius (1915) ^, the zygote divides meiotically to 4 nuclei, one of which is the parent nucleus of the carposporophyte, Avhile the other three are rejected — a method which recalls that of the transmigrant Sjjiro^i/ra^, and is equally bad business, the expression of deterioration in organization, since there is no compensator}^ gam. In JS'emalion, on the other hand, according to Kylin (1916) * and Cleland (1919) •^, the zygote nucleus divides, and a septum appears after the meiotic spindle, a feature not known elsewhere ^ ; the meiotic tetrad is not completed, and the homotype division of the basal segment does not follow^ on, or is incomplete (Cleland). Such a variant on the meiotic mechanism can again be only interpreted as evidence of deterioration in the process, and the haploid sporophyte is thus quite a secondary idea in the life-cycle of such forms, by cutting out a whole phase ; so far affording an interesting light on the deterioration of this other- Avise undoubtedly archaic type, left vestigial in Northern Seas, in which again monoecism and autogamy are the normal rule for the sexual plants 7. The clue to all i^eculiar behaviour on the part of the zygote and young carposporophyte, in its relations to auxiliary cells, is seen in its practically holoparasitic habit ; the idea being to pass as quickly as possible to the nearest source of available food-supply (commonly and most efficiently to the subtending cell of the carpogonial branch, ^ In Gracilaria confervoides tetraspores, antheridia, carpogonial branches, and cystocarps may all occur on the same individual. ' Tetraspores ' on sexual plants are frequent in several species of Polysiplw7iia ; cf. Yamanouchi, Bot. Gaz. (1906), p. 435. The cytology of these organs is so far unrecorded. 2 Svedelius (1915), Nova Acta, Upsala, iv. p. 1. •^ Trondle (1911), Zeitsch. fiir Bot. iii. p. 593.

HISTORICAL REVIEW OF THE FLORIDE^ 33:^ on which the curved carpogonial ramulus is refiexed in orientating it to point the trichogyne to the exterior), as draining the food-supply of the f)arent by taking possession of the cytoplasm of a weaker vegetative cell in the path of conduction, and replacing the original nucleus by an active one sexually produced i. This again is rendered possible by the mechanism of secondary pit-connection, dependent in turn on the peculiarly soft penetrable wall-membranes. It is the blind adhesion to conce^jtions of ' impenetrable,' ' rigid,' cellulose envelopes, based on the stud}'- of the xeroj^hytic land-tlora, that has hindered perception in dealing with the simpler polysaccharide mem- branes of early marine phytobenthon ; and more than any other group the Floridea? present the negation of older misconceived and traditional cell-theory. Probably the clearest view to be taken of the Floridese, as they exist at the present time, is that of a multitude of, so far as they can be traced, quite distinct phyla ~, as the survivors of a specialized and narrowly circumscribed race of Marine Algse, the origin of which is beyond recall ; all the living representatives (300 genera) are on a closel}" comparable physiological plane, and are alike in the attainment of an advanced limiting phase of reproductive mechanism, with a practically constant limiting type of antheridium, oogonium, and unilocular sporangium (as tetra sporangium) : all present the same secondary supersession of flagellated heterogamy, with consequent attached, parasitic, and hence vegetatively decadent carposporophyte, the more so as the latter is immersed in the parental tissues. On the other hand, the phyla diverge widely (1) in respect of types of somatic construction and organization, in correlation with factors of mechanical tenacity, the relative amount of surface-exposure for absorption from the nutrient medium, and utilization of the available light-supply, according to their habitat in the different biological stations of the sea ; but all tending to more quiet water, and taking the chances of depth and diminished light in order to secure it : also (2) with regard to their internal economy, becoming more specialized in relation to the new stimulus of the parasitic carposporo- phyte, which is a drain on the system — and requires to be nourished and 'protected as it becomes less and less able to continue as a mechanically efficient, autotrophic, individual. Ultimately the latter reduces to the status of a mere reproductive organ (of sporangium- habit j, and a mechanism for the emission of the free carpospores may be added to the parental tissues. It is obvious that the phases of haustorial connection, progressively more intimate and devastating in their relation to the parental thallus they drain, constitute but one aspect of the question.

Galavnura, etc. 334 TRR JOUKNAL OF BOTANY of a cystooarpic ivall^ without or with the differentiation of an ostioU after fertihzation, passing on to the initiation of these structui-es before fertihzation (in the special case of the ceramidium), Represents a sev^juence of morphological specialization of a significance fully equal to tliat of the parasitic connection by secondar^^-pits and nuclear migi-ation, as new departures in the race. A true phylogenetic classification should thus combine — (1) the ' auxiliary cell' standpoint of Schmitz, with (2) the special features of thallus-organization, and (3) adult cystocarp-differentiation, more clearly recognized as significant by the intuition of the older algologists (Harvey). And though it may be convenient temporarily to attach an exaggerated signiticance to one special line at one time more than to another, just because it is obscure and hence less known (as in more recent years cytological problems have been regarded as the sine qua noii), pliylogeny takes count of all paths of progress. Apart from the ' general equipment ' of the Floridese as a race, the ' s])ecial lines ' are for practical purposes thus reduced to three ; it may be pointed out that these do not necessarily run concuri-ently ; though in the more primitive types (Helminthocladieae) all are simple, and in the higher types (Eu-Floridea?) all are extremely elaborate (cf. PoJysiiylwnia). The three factors in order of time may be defined as : — I. The evolution of the autotrophic vegetative soma, with differ- entiated members and tissues of special function, particularly in the form of corticated axial-filament types with segmenting apical cells and precise diiferentiation of lateral ramuli. IE. Tlie germination of the zygote in situ, and its parasitic attachment to the adjacent parental tissues as a drain on the paths of conduction. III. The structural response of the gametophyte to the stimulus of the parasitic carposporophyte. The variations expi-essed by the different combinations of phases involving these factors ^ constitute the special charm of tlie Florideaj as a class, far in advance of anything remotely suggested by the more dominant phytobenthon of the Phieophycea? of Northern Seas, as expressed more ])articula]"ly by the familiar Fucoids and Laminarians of our own shores ; this being in turn but the expression of the fact that the Florideaj are pre-eminently tropical in distribi:tion and origin, as deiiizens of the reef-pools of warmer seas ; comparatively few reach n(n-thern watei's, and these are often the last niuch-cnduring relics of a warmer geological epoch. Thus while Boswarva's admittedly imperfect list for Plymouth Sound-, before steamer traffic had fouled the water, extends to 147 species, the Fieroe list at the northern limit of British distri- bution gives only 75 species ; and in the Arctic Sea, according to Kjellman, Spitzbergen, which feels the last influence of the Gn\i- stream, can show 47 species, and the Siberian seas only 11. ^ When the respective value of these three factors can be determined, it will be time to re-arrange the admittedly wholly provisional present classification. 2 Boswarva (1887), Journal M.^B.

Stuaet Thompson, F.L.S. There is an interesting and apparently overlooked reference to, and short description of, Euphrasia minima by the late John Ball, F.R.S., in his paper " On Descriptions of some new Species, Subspecies, and Varieties of Plants collected in Morocco by J, D, Hooker, Gr. Maw, and J. Ball," in Journ. Bot. vol. xi. (1873) p, 272. This paper does not appear to have been quoted by Townsend, Hiern, Marshall, Bucknall, Pugsley, nor any other writer on Enplirasia in this Journal. Mr. Hiern pointed out (Z. c. 1909, p. 165) that Townsend in Journ. Bot. 1884, p. 161, discussed at considerable length the question whether EupJirasia officinalis L. represents a single polymoriDhic species or a collective species ; and at that time Townsend expressed the belief that all the European forms with which he was then acquainted *' are members of a single polymorphic species, and that none of. these members can be ranked as of a higher grade than a subspecies." This opinion, of course, he afterwards modified, as mentioned by Mr. Hiern. But Townsend did quote in this paper on Euphrasia officinalis (1. c.) some remarks in a letter from John Ball in which Ball said that a study of the forms should be connected with that of the insect- visitors. Writing in this Journal (1873, 271) Ball expressed very similar views to Townsend's, when the former was illustrating his ideas of species, subspecies, and varieties, for he said : "In our islands the forms included under this name [^Euph^Yisia officinalis'] differ so slightly, that, as I believe, no botanist has proposed to designate them by dis- tinct specific names, but on the continent of Europe .... we find a large number of such forms presenting wide differences of shape and aspect. The floral organs, indeed, vary little except in size, but the leaves are so dissimilar that if only a few be selected for comparison most botanists would at once refer them to different species." He then proceeded to speak of E. salisburgensis, and remarked that '" The careful observer will, however, find that all the differences which mark these so-called species are no more than exaggerations of the slighter variations which the common plant everywhere exhibits, and further that the groups of forms belonging to one region do not exactly correspond with those inhabiting a different region of the same continent." After a reference to Jordan, Ball adds that "most botanists would rank the remainder as undoubted varieties of E. offi- cinalis^'' and he proceeds : — " There is one among the forms closely allied to our common Euphrasy which shows differences more marked and more constant than the others. This is the E. minima of Schleichei*, a plant inhabiting the higher regions of the Alps, Pyrenees, and Carpathians, distinguished by its dwarf stature, very small, usually yellow flowers, and shortly oval crenate leaves, much smaller than in any other plant of the same group. The mere fact of the presence of this form on several widelv dissevered mountain masses, while it is absent from 336 THE .TounxAL of botany the intervening country, is strong evidence of its high antiquity ; while a comparison between it and several of the forms that we refer to E. officinalis leaves little doubt that it is related to the latter by generic descent. This I am inclined to cite as a typical instance of a subspecies." In Ball's "Distribution of Plants on the South Side of the Alps"' (Trans. Linn. Soc. vol. v. pt. 4, 1896, p. 119) Euphrasia minitna figm-es from 41 out of 50 districts (chiefly Italian) on the south side of the Alps, and from six or seven of the ten other mountain ranges of Europe dealt with, viz. French Alps, Swiss Alps, German Alps, lUvrian Alps (Neapolitan Apennines?), P3'renees, and Carpathians. " In Jaccard's Catalogue de la Flore Valaisanne, Ziirich, 1895, another excellent work in the hands of few British botanists (hence these transcriptions) we find, on p. 281, under Euphrasia minima Jacq., '* Paturages sees, repandu dans tout le pays \i. e. Canton Yalais] 12OO-3U00 m. Cette espece tres variable se rencontre sur tous les terrains sous di^erentes formes et presente une grande extension verticale." The Gornergrat above Zermatt, 3000 metres (Jide Heer) is Jaccard's highest altitude, and he says the* variety hicolor is the most freciuent. Variety minor Jord., is only the reduced form of high stations or of poor soils. The variety jlava appears to him peculiar to the crystalline rocks, and is abundant on the pastures of Conches and at Gletsch (near the source of the Rhone). Variety pallida he records from the Col de I'Eveque, 3U00 m., and from the Paffel and Gletsch. Vaccari gives 3100 m. as tlie highest limit for E. minima and its varieties and forms minor, hicolor, and ^lava on the Monte Rosa massif (see La Flora Nivale del Monte 'Rosa, Aosta, 1911). When studying the altitudinal limits of Alpine plants in the Western Alps during the summer and autumn of 1907 I observed (Bull. Acad. Geograph. Bot. 1908, pp. 195-248) that Euphrasia minima was one of the seventy plants with the greatest vertical range of distribution, though I do not appear to have seen it higher than 2684 m.=i8S00 ft. "(Col Giaset near Mont Cenis) nor lower than about 1000 metres. My Eu))lirasi(e of that year were determined by Wettstein, Chabert, and Bucknall. E. salishurc/ensis and an autumnal form of E. Biclcnelli Wetts. were both collected at a higher elevation than minima, viz. at 2745 m. or 9000 ft. on the Aiguille du Goleon in Dauphine. After ten years' scepticism on the subject of E. minima in Britain (largely because it is chiefl}^ a ])lant of hot dry mountain slopes on the Continent, and has not the leaves and much bmnching of the Exmoor plant), I still believe with Pugsley that what he appropriately calls Euphrasia confusa cannot be I'egarded as conspecific witli E. minima Jacq. But further research into the literature of the subject has shown me how much is to be learnt from the polymorphic genus Euphrasia in regard to plant evolution and distribution, in- cluding the mai'ked differences in forms gathered in Britain and on the Continent of Europe; and not only between plants of separate ranges of mountains but of neighbouring valleys ; as well as about the interesting question of testival and autumnal forms of this and THE GEXUS EUPHEASIA AND E. MINIMA 337 some allied genera in the family Scropliulariaceae. If the vexed and unimportant question of specific rank were the only raison d'etre of the study of these critical plants, I, for one, would regret the time so many have devoted to it. But such investigation is elucidating other and more interesting matters, bearing not only upon the life- history of the plants as known to-day but upon their evolution in different climes and on different rocks, and upon their differences in different countries, the summer and autumn states of some, and the varying degrees of pirasiticism of others. Nor let us forget to follow up the suggestion of that great naturalist and traveller John Ball, when, in writing to F. Townsend in 1884, he drew attention to the part insect- visitors may play. As far as we are aware, no seeds of Euphrasia have been found in the late Glacial beds of Britain ; but Clement Eeid records seeds of the allied Bar^fsia Odontites from the Clyde Beds at Grarvel Park {The Origin of the British Flora, 1899, p. 135), a most helpful book now out of print, and I am told much in demand. The distinguishing features of Euphrasia, Odontites, Barisia, Eufracjia, and of his new genus Disjjermotheca were very ably stated and clearly illustrated (fig. 7) by Beauverd in his paper " Plantes Nouvelles ou Critiques de la Flore du Bassin du Rhone," in Bull. Soc. Bot. de Geneve, vol. iii. (1911), pp. 297-337. In addition to the coloured figures of Euphrasia minima in Schroeter's Flore des AJpes and in my Suh-Alpine Plants, there is a clearer one in the well-illustrated Atlas coloree de la Flore Alpine,. by Beauverie et Faucheron, Paris, 1906..

Ik part 2 of the Prodromus FIorcB Brlfannicce (Nov. 1901), «,fter dealing with the forms of Cenfaurea Jacea L, in a manner aiever before attempted by any native botanist, Mr. F. N. Williams a-e marked that " the critical study of the British Knapweeds has still .to be undertaken." Although many years have elapsed since this was written, very little attention has in the meantime been given to Cenfaurea by our critical botanists, and l^abington's arrangement of the forms seems still to mark the limits of their study. Mr. Williams's survey was chiefly notable for the transference of G. nigra var. deci- j)iens of British collectors to C. Jacea as a variety (C. Jacea \^y. ntffresce7is Wild. & Dur.). In associating "var. declpiens'' with C. Jacea rather than with C. nigra, I believe that Mr. Williams expresses the natural affinity of the plant, though I am unable to iiiirree with his subordination of it to C. Jacea as a variety. NOTE OX CENTAUKEA 341 At present, it would seem that a good deal of field work is neces- sary before an approximately accm-ate knowledge of the various forms of Centaurea can be obtained and their distribution worked out. Botanists who have the opportunity could render important service in investigating whether or not C. Jacea is an aboriginal species in the various localities from which it has been recorded. All specimens of alleged C. Jacea require very careful examination, as it appears certain that allied forms have been erroneously recorded under this name. I here particularly refer to Sussex specimens of G. Jacea, various examples so named having recently passed through my hands. Equally important, perhaps, is an enquiry into the plants recorded by British botanists as C. nigra var. decipiens, as forms nearer related to G. Jacea, and even C. Jacea itself, have been recorded under this name. It may be thought impossible that G. Jacea could pass as G. nigra var. decipiens, but the following shows that it has done so. In Mr. H. W. Monckton's compact little Flora of the Bagshot District (noticed in this Journal for 1916, p. 94), C. nigra var. decipiens (Thuill.) is recorded from the Upper Bagshot sands of Wellington College, Berkshire. Mr. C. E. Salmon has in his herbarium a sheet of Mr. Monckton's plant, which I have seen. These specimens are not what usually pass with British botanists as nigra var. decipiens^ nor do they agree wdth French conceptions of Thuillier's plant. Hearing of my interest in the matter, Mr. Monckton kindly sent me a few dried specimens bearing the same name and from the identical locality, with a note saying that '* this form grows in considerable abundance at Wellington College on the Bagshot Sand ; it is most abundant on the Upper Bagshot Sand but spreads on to the sandy upper part of the Middle Bagshot Sand as well." To my surprise, the examples that reached me were unmistakable G. Jacea L. During the past summer I have received fresh flowering specimens from Mr. Monckton, who has kindly given me much information about the present and past conditions of the localit3\ Referring to the speci- mens sent to me, Mr. Monckton wrote " they are what I meant by G. nigra var. decipiens in my Flora of the Bagshot District. They occur in a limited area here, say, in the square mile between Crowthorne Church and the South -Eastern Railway in the eastern corner of Berk- shire. At the present they are in flower by the hundred or perhaps by the thousand. The ordinary G. nigra is also present and is frequent all around here, both on the Bagshot Sand and on London Clay, but I only find the species of which I sent you specimens on Bagshot Sand and at the particular place above mentioned. I see G. nigra b. decipiens is mentioned in the Sixth Annual Report of the Wellington College Natural Science Society published in 1876 ; it may occur in earlier Reports, but I have not such at hand." As the Gentaurea was so abundant, and no doubt was expressed as to its status as a British plant, I visited the locality to observe under what conditions it occurred. The plants grow chiefly along the border of a road, among turf, etc., for a distance of about half a mile. The road is bounded at intervals by strips of turf of varying extent, but chiefly by shnibs and undergrowth of the heath-forma- 342 THE JOURNAL OF BOTANY tions ; the Centaiireas are found with the grass, and also plentifully among the undergrowth, such as young birch and oak, sallows, JErica cinerea, CaUioia vulgaris, Cytisiis scopcfriiis, liuhi, Aoung I^iniis sylvestris : be^'ond is a background of Piuus sylvesfris and Cedriis JJeodara. The Centaureas occurring under these conditions i^ave me the impression of being intrusive species, naturalised but decidedly not aboriginal. Centaurea Jacea, very variable as to bracts and as to whether the heads are radiant or not, is abundant, the var. longi- folia Sehultz-Bip. being well represented. Here are also a n amber of puzzling allied forms very similar to others found in Surrey, where I am disposed to consider them native. The most notable of these allies was G. pratensis Thuill. Under other conditions I would readily accept this as native, as it is a well-distributed British plant, ranging from Kent to Perth, and represented in herbaria under such names as C. nigra var. pallens Koch; C. nigra var. clecipiens (Thuill.) of British authors (Syme, etc.) ; it comprises most of the plants referred by Mr. Williams to C. nigra var. rivuJaris. As to the source of introduction of these plants at the Berkshire localit3% the adjoining pla^^ing-fields probably offer the solution, as whilst the ground devoted to the summer games was well mown and rolled, the football ground was covered with a thick growth of flowering and seeding Centaureas of various kinds. Grass-formations do not naturally occur on the dry Bagshot Sands, and tlie playing- fields have no doubt been formed by the laying down of turf or by the sowing of gmss-seed, the Centaureas being present in the turf or the fruits being mixed with the grass-seed.

Salmon, F.L.S. [In printing these notes, made b}^ my late friend Anthony Wallis in 1916, it may not be out of place to give a few particulars of his life. Born at Reading July 14, 1879, Anthony Wallis was educated at Leighton Park School, passed one year at Owens College, Manchester, and entered King's College, Cambridge. Here rowing absorbed much of his leisure, but time was found to compile "The Flora of the Cambridge District," mainly upon ecological lines, for Marr and Shiplev's Natural History of Cainhridyesliire, 1U04. After taking his degree with Second Class Honours in Nat. Sci. Tripos, and studying and ])assing in Pedagogy at Bishop Stortford School, he was, at the early age of 23, appointed a Junior Inspector for Bucks of the Education Department. Stationed at Aylesbury, a good centre for botanical as well as educational activities, plant- hunting claimed a large part of his spare time ; Gladium Mariscus was discovered by him in the county (Bot, Ex. Club Rep. 1904, 35) and many records were supplied to Mr. Gr. C. Druce for inclusion in his forthcoming Flora, such as Anemone Fiilsatilla which we found on the Downs. From Aylesbury, Wallis was transferred to Leeds, and subsequently became Junior Inspector to the North Riding with headquarters at Darlington. Whilst there he married Miss A. E. Mounsey, of Blackwell Hill, near Darlington. After a few years, during which many botanical observations were made during vacations (see Journ. Bot. 1910, 225, where Luzula arcuata is mentioned from a fresh station, Ben Nevis, and Journ. Bot. 1916, 165), Wallis was given the Senior Inspectorate for Cum- berland and Westmorland with headquarters at Penrith. To work thoroughly these mountainous counties, ill-served by road or rail, ])roved almost too much for his strength even with the help of a car ; the arduous work of bicycling long distances in all weathers, when the car was stopped during the War, brought about lung and other troubles and ultimately caused his death, which occurred at his house at Penrith on August 28th. 2b 2 3-iS TUE JOUK^AL OF EOT AN 1' His friends regret the loss of a charming personality and an ideal companion.

Riddelsdell. Adonis annua L. This was recently found in considerable quantity in corntields about Culkerton and Rodmarton b}^ E. M. Day. But it is nowadays far less frequent than formerly. Ranunculus ophioc/lossifolius Yill. is remarkably uncertain in its appearance, rarely making so^ great a show as it did in 1912. It seems to have " periods " very similar to those of many orchids. When I visited the locality at the end of August 1919, signs were not lacking of a gradual change in its character, a change which may possibly prove fatal to the plant : for farm-3^ard species of Afriplex and ChenopocUum were beginning to encroach. It is to be hoped, however, that a more normal season may witness the return of the locality to its old bogginess, and that the buttercup may long survive. HeUehorus fmtiihis L. is undoubtedly native on the Cotteswolds, which, as a friend suggests, are probably the head-quarters of the species in Britain. This is an opinion I have long held with respect to the Ely Orchid and Polygonatum officinale. The latter is quite a common plant on these Hills, occurring usually in company with the Lily of the Valley: whereas P. mulfiflorum is decidedly scarce there. These facts, coupled with the occurrence of Staclnjs alpina and the abundance of Thlaspi perfoliatuni, Carex foment nsa, Cephalanthera rubra, &c., serve to emphasise the unusual botanical importance of the area. GlauciumJJavum. Ci-antz. AVell known on the Bristol side of the Severn.

The various records do not suggest a native plant: yet it seems an unlikely species to be carried any distance. It occurs, of course, in abundance fai-ther down the Bristol Channel, in Glamorgan and Devon, and may possibly be a dying-out species here. It is not GLOUCESTEESHIEE NOTES 351 always confined to tlie actual coast : I have knoAvn it flourisli in Glamorgan on rocks 2 or 3 miles inland. Thlaspl perfoliatum L. occiu-s in such abundance in districts 1 (5 miles from Campden), 6, and particularly 7, that it may be regarded as one of the characteristic Cotteswold plants. It happily occurs usually in such out of the way places, and on such stony and " useless " soil, that it is most unlikely to disap])ear. In some neio-h- bourhoods, it can be found on almost every suitable-looking piece of bare soil. On one occasion, I looked over a low wall into some Avet ground for a chance of bog plants, and was surprised to find the reverse side of the wall for some distance covered with a luxm*iant growth of T. perfoliatum 4 to 6 inches high.

Sfellnria Rolostea L. A form has been sent to me by J. W. Haines from Birdlip with petals shortened and more deeply cleft than usual. The sepals are also sometimes shortly ciliate in their lower half. I suppose this is just a step away i^-om t^'pe towards the apetalous form. Geraniinii columbinum L. is a frequent and characteristic plant of rough stony upland pastures on the Cotteswold Hills : more at home there than any other species of this genus. Biihiis Godroni Lee. & Lam. var. clivicoJa Ley appears to be a common bramble of the neighbourhood of Birdlip, usually occurring at 800 to 900 feet of elevation. Too man}^ of the Buhus records for v.c. 38 rest on the occurrence of a single bush or at best a single clump : but much work remains to be done in the genus, as far as E. Gloster is concerned. Pyrus scandica Aschers. This species (I believe) occurs in quantity with P. Aria in a grove near the top of Haresfield Hill v.c. 38. As JBetuIa is there too, both are probably introduced in the locality. Chrysospleniu7n alternifolium L. is a species characteristic of ditches and small streams in deep shade all over the Cotteswolds. It is, 1 believe, even more frequent than G. oppositifolium. Carum Btilhocasfanum Koch has of late years been found by several botanists in cornfields near Cheltenham. It is an introduced plant in this locality. Senecio integrifolhis Clairv. has been found at different times, usually in very small quantity, in three or four spots on the Cottes- wold Hills : on one occasion T saw it in great quantity and luxuriance. But sheep nibble it and it does not get much chance. It is not a characteristic plant of the Cotteswolds, and is quite uncertain in its appeai-ance. A few plants were seen on downs near Northleach last year. Cenfaurea Scahiosa L. In August I found a clumji of this species between Cheltenham and Birdlip, with the heads of fiowers 352 THE JOURNAL OF BOTANY niiicli smaller than usual, ami lacking the ray florets. If it is an3'- thing more than a lusits, the form deserves naming as a variety, Cynoglossum montanum L. A MS. note of F. Townsend's records this note from "woods near Chastleton, but whether in Glos or Oxon I know not." Verhascum nigrum X ThapsKS. I have this hybrid both from the Sheepscombe and the Slad Valleys, near Painswick. Teucrium Botrys L. I saw this species again last August : it v/as in great quantity and extended even into a second field. I am not quite sure that it is exactly the spot to which I w\as taken some years ago : if not, there are two large groups of the plant, within a mile of one another, near Sapperton. Betula alha L. grows on the top of Haresfield Hill, and occurs on the lower slopes, near the Edge-Pitchcombe Road, as small scrubby bushes. It may be native here, but I doubt it. It so greatly prefers wood on damp or even boggy soil that its appearance on these dry calcareous slopes looks most unnatural. Cephalaiithera rnhra Rich, turns up in some fresh spot every year. It is recorded from at least a dozen places, all within our dis-. trict 6 {i.e. south of BirdHp). In most cases one or a fcAV plants only are found. In only one case do I know of it in considerable quantity, and I am told that even there it is diminishing. The felling of a wood threatens to destroy it in one place, for the timber is left lying on the very space where the plant grows. I have one record for G. rnhra from district 7 h, but it is probably an error. Orchis liirciiia Crantz. Mr. Druce told me that he had seen a 1917 specimen from the Painswick neighbourhood, and I have since seen the finder and been told Avhere it grew. Mr. Horwood wrote to me of his good fortune in discovering it again in Suffolk that je-AW The finder of the one Gloucestershire plant (v.c. 33) described the peculiar behaviour of the open flowers, w^hich have the habit of " following the sun round" during the day, so that they always face it, in whatever part of the sky it is. 0]iliri/s apifera Huds. var.

In v.c. 33 certainly, e.g. in the Stroud water- valley, and at the Seven Springs on the R. Windrush. Potamogeton Friesii Rupr. occurs not only in the Stroudwater Canal, but also in the R. Leadon : i. e., it is found in v.c. 34 as well as 33. Scirpus co)npressus Pers. is a plant characteristic of the tops of the Cotteswolds. Almost every wet grassy open j^asture produces it, and many bogs in woods. Here it is entirely at home, though j)er- haps it would, as a rule, be expected on lower ground in other areas. Erioplwrum lafifoJiiim Hoppe is being found more plentifully in Gloucestershire, in both vice-counties. A bog on the hills near Newnham has it. Carex tomentosa L. Buckman's record from the Cheltenham district was for many years rejected. But the species is found near the sources of the Colne at Withington. A sedge first known from Marston Mevsev in Wilts, it turns out to be charactcristicallv a GLOUCESTERSniRE I^OTES 358 native o£ the Colne drainage, for it has been found lately on the driest parts of the elevated downs near Northleach, and it is quite frequent in the lower Colne Valle}^ about Fairford. It appears to be quite indifferent to the amount of moisture in its neighbourhood, as indiiferent as C. glauca, with which it appears to hybridize : I have seen plants which seemed to be this hj'brid growing at Whelford, and a similar intermediate was sent me from near Northleach. C. strigosa Huds. is quite of frequent occurrence in E. Gloster ; it is not confined there to woods, growing in one place in a ditch under a heds^e. Foa palustris L. var. ejfusa Asch. & Graebn. Has at last been found in v.c. 34, and so is now on record for both parts of Grloucester- shire. Lasfrea montana T. Moore, a specimen from Cranham Wood, is in St. Brody's Herbarium : this is in v.c. 33. I have seen JPJiegopteris Dri/nptPris in minute quantity at Cranham in v.c. 33, and Botry- cliiiim Lionaria Sw. in v.c. 34 near Tidenham Chase. Ferns are, as regards quantity, much scarcer in E. Glos than in W. Glos, yet there are only one or two species present in the latter and absent from the former. Aspleniiim la nceolafum dLiid Lastrea (Simda stand, I believe, alone in this category. T should say that probably the Cotteswolds are the headquarters of the Limestone Polypody in England — at any rate, I know of no other area where it is so ubiquitous. BIBLIOGRAPHICAL NOTES. LXXVIII. " John Frederick Miller and his Icoxes." In the note (LIII.) published in this Journal for 1913 (p. 255) I described at length a fascicle of seven plates to which I had not then been able to find any reference, and which, owing to the fact that they were bound with the Icones Animalmm et Plantarum of John Frederick Miller in a volume lettered on the back " Miller's Plates," I then attributed to that artist. I now find that the fascicle is described in the Supplemenfum to Dryander's Catalogue (v. 63), the words " Plures non prodierunt " being added, and it is alsO' mentioned in Diet. Nat. Biogr. xxxvii. 413 — in both places it is accurately ascribed to John Miller, the father of John Frederick. As the plates are all lettered John Miller, my mistake, which cair only be accounted for by their correlation with John Fredericlv's. work, is inexcusable. James Britten. SHORT NOTES. Habitats op Hypericum humifusum (pp. 195, 225, 2S7)„ Mr. H. S. Thomps(m notes the frequent occurrence of this plant on " rides " in woods upon Carboniferous Limestone, though most ecologists prefer to regard it as a lime-hater. In West Somerset its 3,j4: the J0UR>'AL of BOTAXr usual habitat is in open woodlands upon a siliceous formation ; it is a common and bj no means a thinl}^ distributed plant on the sparsely wooded portions of the banks of the river Barle. It occasionally occurs on roadside banks where these are damp or shaded by a wall, as at Exford, or by overhanging trees as at Xettlecombe. Its occur- rence in other situations is, as Mr. Tliompson remarks, almost certainly due to the agency of man. During this summer I found it in a recently cleared woodland, in a district where I had not previously noted it. Its occurrence upon limestone soils must be looked upon with suspicion ; it is not a deep-rooted plant and the soil may, as Mr. Woodraffe- Peacock says (p. 225), be "acid sandy above, or the upper root-soil is neutral from endless rain-wash and plant-decay." Wrington Warren, where Mr. Thompson notes its occurrence, is an example of a ''calcareous heath"' where many lime-hating bryophytes are abundant. In July of this year I found it growing abundantly in a fallow corn- held near Kayleigh's Cross on the Brendon Hills, where most of the plants associated with it suggest a calcareous sub- stratum, the floristic composition of the field being very similar to that on White Lias pastures. Of the chief plants noted the following, besides the Hij peri cum, were abundant: Geranium columhinum, Shei'- ardiaarverisis, Th y mus Serpyllum, Rumex Acefosella ; Ononis repens, Alchemilla arvensis, Filago germanica, Euplirasia rosthovia7ia, E. ciirfa, Barfsia Odontites, Calamintlia arvensis, Plantago lanceo- lafa, and Aira carifopJiyllea were occasional. The abundance of H. humifasum and B. Acetosella amidst such company presents an ecological problem, the solution of which may lie in the superficial Sir F., 200. Gregory, R. P., 47.

THE PH^OPHYCEAN ZOID. By a. H. Church. Considered as a ciliated reproductive cell, the characteristic "zoospore" or "swarm-spore" of the Phseophyceaj presents little interest ; but regarded from a broader standpoint as the retention of a flagellated phase in the life-cycle, linking this great group of marine algae with other flagellated races of phytoplankton, it acquires an intensive value — not only as opening up the question of the flagellate ancestry of the Phseophycese, but as expressing the high- gi-ade differentiation attained by such a zoid in some previous phase of existence and its isolated phyletic history. The organization of the Phseophycean zoid as presented most typically in the zoogonidia of Ectocarpus, the gametes of Laminaria^ or the antherozoid of Ficcus, is that of a simple naked protoplast, rounding off at about 5 fx diam., with nucleus, suggestions of granular cytoplasm and either a single discoid chloroplast reduced to an eye- spot {stigma) only, or associated with such a residual plastid ; larger zoids may contain several chloroplasts. Such a zoid, though typically possessing autotrophic mechanism, differs in one fundamental respect from a typical flagellate, in that it has lost the power of binary fission and is so far retained wholly for a " reproductive " function. On the other hand, many '* Brown Flagellates " are similarly re- stricted to binary fission in the non-motile "cyst "-stage (cf, Hyclru- rus, PhcBosphcera, PJiceocapsa, Hymenomonas). The zoid is thus to be regarded from the standpoint of the organization of a flagellate, though such details have been as yet but little investigated. Though generally described as pyriform in shape, with pointed anterior end. the protoplast possesses little in the way of a permanent space-form ; when at rest the body rounds off in response to surface- tension ; and in the motile stage the pointed end is largely the expression of " metabolic " or '* euglenoid " contractility ; in this way a 5 /z individual may extend to 7-10 or 12 ^ in length, as an elon- gated zoid with active movements. The point of insertion of the fiagella must be regarded as the '*;?oZ<9" of the zoid; and in such case the direction of the movement implies a change of polarity, of about 90'^, from the original condition of the isokont phase with equal distally inserted fiagella. A similar change of polarity obtains in other flagellate phyla, noticeably in many Cryptomonads (cf. Nephroselmis), and in the Peridiniaceae, with a very similar result ; and this is undoubtedly correlated with a differentiation in function between the two fiagella, as expressed in a reversal of the direc- tion of contractility in one which becomes a propeller, while the other remains a tractor. With two fiagella thus widely divergent, and falling into line at 180° with each other across the axis of antecedent polarity, both act in the same direction, and a new " anterior " end is acquired. Details of zoid organization in terms of flagellate construction are still meagre : — Yamanouchi (1913) for Zanarduiia described a suggestive chain Journal of Botam. xA.peil, 1919. [Slpplemem Jl.] 2 THE PH^OPnTCEAN ZOID of granules between the insertion of the flagella and the nucleus, in the manner of a rhizoplast-strand, but decided against any connection between such basal granule and a blepharoplast as a " cell-organ." lletzius (190G), for Fucus Areschoiigii and F. seDYrfits, showed the presence of a group of 4 (rarely 5) " Nebenkern "-granules (Mito- chondria, Plastochondria) probably of nutritive function, and confused by previous observers with the nucleus (Guignard). Ketzius also demonstrated the " end-piece " of the flagella, as a short delicate terminal portion (5/i long), regarded either as a projecting core (Minchin, p. 52), or as a prolongation of the extreme plasmatic him. Meves (1908) confirmed the presence of plastochondria which might become confluent, and also demonstrated distinct "basal granules " in Fucus serratus associated with each flagellum, to be described as "centrioles" ( = blepharoplasts), and in direct contact with the nuclear body of the protoplast. According to Meves also the two flagella of Fucus ser)Y(tus grow round the zoid in the same sense (cf. (-hara), while according to Retzius they are so exactly in the same line that they appear as pi-actically continuous. Older hypotheses that flagella are formed from a peripheral zone of cyto- plasm (Guignard, Yamanouchi, 1913) require to be replaced b}^ the view that they grow outwards from the point indicated by the basal granule, in the manner generall}^ characteristic of flagellates (Minchin, P-^2). The special feature of the mobile zoid is its asymmetrical organi- zation as expressed in the " lateral insertion " of the two unequal flagella ; and this arrangement, so constant and characteristic, is in marked contrast with the isokont habit of the zoids of the Chloro- phyceai-lsokonttfi and Chrysomonadina-Isokontse. It ma}^ be termed the '' anisoko7if^' condition. Of the two flagella one projects forward beyond the pointed anterior end as a tractor mechanism ; the posterior merely trails behind as a long '' steering-oar " : to what extent it acts as a definite propeller is still obsciire. The names " tractor " and "trailer" maybe adopted as suflSciently distinctive and concise (Minchin, p. 53). hohont is preferable to isomastigote, and ft ni>!o]iont to heteromastigote : "trailer" is preferable to guhernaculum (cf. Willey & Hickson in Mastigophora, Lankester's ' Zoology,' i. (1909) p. 158, Minchin, p. 259) ; Lankester (Enc. Brit., Protozoa) introduced the terms tractellum and puUellurn respectively, the latter indicating the propeller; and the?e terms have been retained in works on Protozoa, as Saville Kent (1880), Infu oia; Minchin, Pio'.ozDa (1912), p. 52. On general principles it may be concluded that the asymmetrical habit is secondary, as the transformation of a symmetrical mode of construction ; and that the differentiation of two flagella with different fimctions is secondtiry to that of the type of the isokont green algffi ; the latter may be so far regarded as a more primitive phase of zoid construction ; as in turn the condition of the single anterior tractor-flagellum may be considered to represent the first step in the evolution of such a kinetic mechanism. Zoids with a monokont organization survive in the case of Botrtjdium (Chlorophyceae), and among several groups of Brown Flagellates (Chryso- monadina-Monokontae, Silicoflagellatae, Coccolithophoridae, Hydrnnis ; among Fungus phyla in Chytridiaceae and Monohlepharis ; in vestigfial flagellated Eadiolarians, flagellulffi of Mycetozoa, and as reproductive phases in Foraminifera as Peneroplis. The Isokont condition is characteristic of Chrysomonadina-Isokontee THE PH^OPHTCEAN ZOID 3 ( = Hymenomonadace£e), Green Algae, as marine Codium and freshwater Volvox, etc. ; aa also as flagellated phases of many Heliozoa, Radiolaria, Chara, the Bryophyta, and even Selaginella. The movement of the anterior tractor is always that of a sharp rhythmic contractility in three-dimensional space, working out a movement which Avould be observed as a spiral vortex if the zoid were still ; but being freely suspended in the medium the body is pulled along and at the same time rotated on its axis, while the movements of the tractor appear as a mere undulatory lashing like tha shaking of a rope. Such a mechanism is clearly the expression of a limiting term of economy and precision in swimming, and it is to this that it owes its constancy. It can be only improved by increasing the effective power of the tractor, as by increasing the mass of the contractile plasma, or by adding to the length of the stroke. The feeblest monokont flagella are usually about one body-length (flagel- lulae of Mycetozoa) ; yet many Cryptomonads are intensely active, with darting action, with flagella relatively no longer (Cliilomonas). In megazoids of the Phseophyceae efficiency obviously falls off as the flagella are left less than one body-length. The most efficient are 3-4 body-lengths, though ranging to 4-6 body- lengths with more rounded zo'ids {Dictyota). Among the Phfeophycese the finest expressions of the type are found in the Cutleriaceae (Yamanouchi). Thus :— Cutleria megazoid 26/j long, ovoid, anterior flagellum 40ju.. Aglaozonia zoid 22"5/it long, ant. flagellum 65^. Zanardinia, zoogonidium 22'5 long, ant. flag. 45/i. Where the zoid is enlarged in correlation with phenomena of heterogamy the relative dimensions are diminished ; and the large oosphere of C^itle7-ia with 30 chloroplasts presents an anterior flagellum of 40/i only, or 1*5 body- lengths. It may be noted that 3 body-lengths bears a suggestive relation to the circumference of the zoid, as one complete turn of the body in ontogeny. In many more specialized and powerful holozoic flagellates, the tractor- flagellum is distinctly broadened to a band-form. [Cf. also Euglena, Cyathomonas, and animal spermatozoa (Retzius, 1906, Doflein, 1916, p. 38).] Again, regarded as complex kinetic organs of primary signifi- cance involving problems of life and death to the organism, such flagella are the result of long and complex natural selection on pre-existing factors of growth and contractility. Their structure, as presenting a thin him of intensely katabolic contractile plasma apparently investing an axial core of more resistant endoplasm, possibly affords in its minute dimensions ('5 /j, diam.) as vivid an idea of the complex nature of living plasma as any other part of the cell ; such a structure as the first evolved " member " or " organ " of the cell-soma, projecting far beyond the limit of the main body, must involve a special system of conduction, nutrition, and control, of which little is yet known, but is to be considered from the standpoint of "basal granule," *' mitochondria," and *' rhizoplast." The primary function is undoubtedly that of a means of vertical ascent for autotrophic photosynthetic pelagic ph3'toplankton ; lateral progression in such a medium is meaningless : but it is obvious that 4 THE PIIJEOPHTCEAN ZOID in the case of increasing mass or form-resistance in the body of the protoplast, the vortical motion will become a means of impelling food-particles on to the point of insertion of the tractor ; and in the vast series of more dominantly holozoic flagellate organism this becomes the essential mode of " feeding " ; such particles being absorbed, ingested, and ultimately digested in an oral depression, cytostome, or gullet, as the " animal " flagellate is more definitely outlined (cf. ChiIomo7ias, Cyatliomonas, Gymnodiniaceae). No trace of such holozoic nutrition has been observed in any zoid of the Phceophyceae ; and the utilization of these as non-metabolizing re- productive cells suggests that any such tendency will be further eliminated in their short life-period (as the anterior tractor has been apparently eliminated in Metazoan sperms). For ingestion by Green Algal zoids cf. Pascher, Berichte xxxiii. p. 427. Secondary increase in volume obtains throughout the group in several series independently, as heterogamy progresses (to define the *' female " gamete), as also in the case of the correlated increase of the asexual zoogonidia. In such case the zoid retains its general attributes ; the chloroplasts may be greatly increased in number, and the flagella keep pace to a certain extent ; in extreme cases, however, the latter begin to dwindle ( Qiffordia virescens, Pylaiella ful- vescens Sauvageau *, 1896), and may be apparently wholly lost (^Aci7ietospora Bornetf), though euglenoid motility may be retained. In the larger megagametes (** oospheres ") no trace of flagellation remains, and the same applies to the correspondingly enlarged tetra- spores of Dictyota and the *' monospore " of Haplospora. Interest also centres in the evidence of distinct reduction in the case of the microgamete (antherozoid) in correlation with the differentiation of heterogamy and the relegation of the zoid to the mere value of a " sperm." Thus in Fucus serratus, according to Eetzius (1906), the body of the zoid is practically restricted to an oval nucleus, more or less flattened (Meves), to which the C3^toplasm constitutes only a thin film, more exaggerated to form the anterior pointed end. The residual '* ej'e-spot " and the " mitochondrial a))paratus " of 4 granules (often merging into one, Meves), whether of cj-^toplasmic nature or merely physodes (Kylin), so far project from the surface of the plasma-film, and may be even stripped off (Retzius, Biolog. Untersuch. 1906) %. The case of Dictyota suggests the gradual elimination of the shorter '* trailer," reduced to negligible proportions in Gi^ordia virescens and Pylaiella fulvescens (less than | body-length) ; and in such case a residual tractor is curiously complementary to that of the animal sperm with propeller only. The chloroplast-content is reduced to a vestigial eye-spot {Fucus, Dictyota, Laminaria); and the eye-spot may be pale in * Sauvageau (1896), Journ. de Bot. p. 185, for Pylaiella fulvescens, Giffordia, p. 119. t Bornet (1891), Bull. Soc. Bot. p. 357, for Acinetospora, X Retzius compares the mitochondrial mechanism (Nebenkern-system) with that of the sperms of Nemertines and simpler Mollusca of the sea : Biolog. Untersuch. 1906). THE PHiEOPHYCEATf ZOID 5 colour, giving no carotin-reaction {Pelvetia, Durmllcea) ; but in no ease can it be said to be wholly eliminated. The function is un- doubtedly that of light-perception, while in ontogeny it is always derived from a localized area in a chloroplast (Yamanouchi), and the orange pigment ("carotin ") apparently indicates that the cytoplasm must be stimulated by the absorption of violet rays. The zoids in no case swim backward (as is normal for an anterior tractor-mechanism) ; but as they slow down they move in larger to smaller circles as the expression of the loss of steering-power and some sense of direction. Apart from any question of nutrition, the flagellum acts as a tactile sensitive organ ; thus in response to stimulus of contact, as in collisions with foreign objects, the zoid may slightly change it course (cf. Jennings, 1904). This sensitiveness is emphasized by " chemo tropic " phenomena, and apparently repre- sents the factor of greatest significance in the employment of the zoid as a *' sexual " cell. Thus in Cutleriacese (Yamanouchi) the anterior flagellum is the first to come out of the gametangium, and first makes contact with the other gamete. The spinning of the oospheres of ¥ucxis and Ascophyllum in fertilization is apparently the expression of the activity of the shorter anterior arm in the antherozoids of these types, when the longer trailer ia entangled in the oosphere. In other genera (Halidrys, Himanthalia) the sperms entangled by the longer driving anterior tractor merely gyrate on the point of contact. Euglenoid movement is always retained, and the larger zoids bend and curve, or " nose about," in a very suggestive mouse-like manner, exhibiting contractility all over the body-surface as a general property of the cytoplasm. Amoeboid movements are more rare ; but irregular protrusions of pseudo- podia-like nature may follow benthic attachment to the substratum in germinating zoids of Myrionema. Exact data for the speed attained are wanting ; it would appear that 1-2 ft. per horn* is a fair rate for a 7 yu zoid ; but active units do better than this for short distances across the field of the micro- scope. As seen under the microscope the movements are wholly erratic, like those of a swarm of ants, or mice in a box ; and it would be absurd to interpret the motor mechanism only in terms of such observations. Under the low power it is possible to time zoids along the scale of the micrometer eye-piece ; and a moderate estimate for gametes of Lajninaria saccharina gave 1 mm. in 5 seconds, or over 2 ft. an hour ; gametes of Ectocmyus are half as quick again. The large zoids of Pylaiella fulvescens, according to Sauvageau, do not move faster than a Diatom. The rate again probably bears a relation to temperature and oxygen-supply, as well as to the condition of the material. Measurements are difficult for longer distances, as the field of the low power is only 2 mm. diam. : Sauvageau records zoids crossing a 5 mm. drop in about a minute, or approximately a foot an an hour. Records of the duration of the motility are vitiated by observa- tion in water in which a full oxygen-supply is not maintained (as * Jennings (1904) ' Behaviour of Lower Organisms.' 9 THE PH.EOPHYCEAX ZOID under a covei'slip). *' Several houi*s " is the rule ; many swim all day, but none have been checked longer than 24 hours (Yamanouchi, for Zaiiardinia^ 1913). In open water there seems to be no reason why zoids with several chloroplasts might not continue for much longer periods. For the shorter motile phase of more decadent types Sauv^ageau gives 4-5 minutes for the megazoid of Giffordia virescens^ and 15 minutes for the microzoid. In other examples the *' megazoid," only just tumbles out of the gametangium, or is discharged immo- tile {Acinetospora) ; probably all transitions occur. From such data it would appear improbable that these zoids can raise themselves from any great depth ; though they do so freely enough in culture vessels, spreading out as a film on the surface {Cutleria, Aqlaozonia). Monstrosities in zoid-segregation suggest further points of interest as tending to throw light on the organization of other zoids. The occurrence of ** twin "-zoids, apparently due to the imperfect separa- tion of protoplast-primordia in the '* sporangium " is described for Pylaiella fulvescens (Sauvageau) 2Lwdi Aglaozonia (Kuckuck). The more aberrant case of a "triplet" zoid in Aglaozonia (Kuckuck, 1899, W. M. K, p. 103) with triangular arrangement of 3 clear "anterior ends," and a single flagellum on two adjacent sides, is of special interest from the standpoint of the suggested flagellated phase of the Diatom Biddulphia mohiliensis (Bergop, 1907, Bull. Soc. Bot. p. 348), in which a protoplast is figured with 3 " flagella " at three angles. Several phyla of the Phteophycese are distinguished by distinct variants on the type. In Phaeosporeae the zoid is typically ovoid, with distinctly-pointed anterior end, and two flagella inserted laterally near the pointed anterior end : the anterior (tractor) flagellum is 2-3 (or 4) body-lengths, and the trailer short (one body-length). Through- out the Laminariaceae and Cutleriacese the same type prevails ; but among the more advanced Fucoids of the Cys^ost, the plankton-rate would work out as 2400 times that of the suggested mean rate ; such a culture again remained healthy and intensely active for several months without any indication of toxic effects, while surface-aggregation might represent a rate of 40,000 per drop. Observations by Raben (1910, p. 310) give the total Nitrogen- content of the sea (Mediterranean and North Sea) as sometliing between '1 and 2 mg. per litre (rarely exceeding -2), or -0001 g. per litre = 1-2 parts in ten millions also ; a very similar result was THE PLANKTON -PHASE AND PLANKTON-IIATJE 7 given by Raben for the Phosphorus -content (as ^fi^), at "14 mg. per litre ; though according to Matthews the amount in the English Channel (Plymouth, 1918) is much less, or -06 mg. per litre in winter (maximum), and -01 mg. as the spring minimum, or as little as one part in a hundred millions. There is nothing to show that plant-organism can exhaust all the available N and P ions in the solution ; and it may be noted that all such estimations have to be made in the case of water already occupied by living plankton ; while a considerable source of error must exist in the large amount of dead and decaying or macerating debris of plasmatic organism which apparently appears in analyses as " organic " nitrogen and "organic" phosphorus (Matthews). Thus according to Raben the nitrogen value rises in summer, as if from the greater death-rate at a higher temperature ; and though Matthews accords a higher phosphorus value in winter, it may be pointed out that his results for water taken near the sewage outfall of a large town, presumably supplying enormous quantities of microcosmic salt, give only *0G mg. per litre, suggesting that excess phosphorus compounds are rapidly precipitated as insoluble phosphates. From an interesting table of analyses for various marine invertebrates (Delff, 1912), it may be taken as a general estimate that the water-content of such organism varies from 70-90 7o» the nitrogen-content (N) from 5-10 7o> ^"^^ "the phosphorus- content (P.Ps) as about -^th of the nitrogen value. This may be probably taken as an approximate estimate for animal cytoplasm with little waste ; and though plants with accumulated polysaccharide debris would give a much lower rate for nitrogen, of possibly only a third of this value (Brandt, 1898, p. 58) ; it may be also taken as approximately correct for zoospores and mobile naked flagellates. "With the sea containing nitrogen ions at about one in ten millions, and plankton at the mean rate also of one in ten millions, it would a])pear that the plankton of a litre would not cover more than ^-y^ of the available nitrogen. In such case it is interesting to compare the figures of Lohmann for total autotrophic plankton (including Peridines) alread}'- given as suggesting an approximation to the nitrogen limit, as also the later figures of Allen (1919) for a suggested million of autotrophic organisms per litre (Diatoms, etc.), many of which may be several times larger than the hypothecated 5 /a zoid ; but the subject is again confused by the fact that we are still ignorant of the actual cyptoplasmic value of a Diatom, as compared with the " volume " of its vacuolated " cyst "-stage. Though the scarcity of Nitrogen ions is not definitely established as a limiting factor for pelagic life, the fact emerges that the actual quantities of living material and the more essential ions of the medium are in a stiite of somewhat comparable spatial tenuit}^ Although again clearly of no veiT exact scientific value at present, such considerations are justified as affording a general idea of the conditions under which living- organism has been evolved in the aqueous phase of the sea ; and the suggested "mean plankton -rate " may be useful in establishing some general basis for the consideration of the economy of the phyto- plankton and phytobenthon of the British coasts.
