SPROESSER) 1914 REVISION OF FLORA PATAGONICA. PREFACE. WHEN the lamented John B. Hatcher and his assistants returned from their geological trip through southern Patagonia, in 1896- 1899, they brought home with them, besides geological col- lections, and some interesting zoological prizes, a collection of flowering plants and mosses, which had been found in the region of the Rio Sta. Cruz, and by Magellan Strait ; not far from the region in which the youth- ful Charles Darwin made his famous observations on the growth of plants as well as on the evolution of mountains. And although botany was only a minor branch of my work in biology, I was requested by my colleague, Professor W. B. Scott, chief editor of our Princeton Patagonian Reports, to furnish a report on the Patagonian botany. In order to meet his wishes, and in order to have the Mosses correctly determined and described, I appealed to Dr. Per Dusen, of whose botanical researches in that country I had seen high commendation in the columns of Nature. Dr. Dusen's reply and generous help as to the Bryophytes enabled me to start and carry out the undertaking, so as to secure provisional identi- fications of the flowering plants ; whilst Professor Evans, of Yale Univer- sity, and Professor W. Lucien Underwood, of Massachusetts Institute of Technology, helped me with the Hepaticae and the ferns. My portion of the affair, on the Phanerogams, was carried out usually in the Philadelphia Academy of Sciences, in the Bronx Botanical Museum of New York, through the courtesy of Dr. N. L. Britton and Dr. J. K. Small ; and in the Gray Herbarium, Harvard University, where the fair curator, Miss Mary Anna Day, and the valuable South American specimens which bore the handwriting of my beloved friend Asa Gray, were a great help. It was impossible under these circumstances to make dissections ; and I \va^ therefore compelled to content myself with prima facie comparisons. Yet so correct a botanist as Professor Carl Skottsberg, of Uppsala University, himself an experienced Patagonian explorer, is good enough to say, that, 2 PATAGONIAN EXPEDITIONS: BOTANY. thanks to Dr. Dusen's assistance, most of the specimens have been prop- erly named. It was part of my plan to make the work of permanent value, by having it well revised ; and once more I appealed to my generous friend Dr. Dusen. Whilst he was engaged on this troublesome business, Professor Skottsberg wrote to me for specimens of the plants, thus ensuring a double revision ; and both have now carefully completed their work. Their reports, though prepared independently of each other, are singularly harmonious in the outcome. In a few cases I find it best not to combine them, but to give each separately, leaving to the readers the privilege of comparing them. I have also had the benefit of notes on some Gramineae by Dr. Teodoro Stuckert, of Cordoba, Argentina ; determinations of species of Accena by Professor Bitter, of Bremen ; notes published by Professor Rendle, of the British Museum ; and the revision of Cruciferce by Gilg and Muschler in the Botanisches Jahrbuch. And I beg to thank all these gentlemen for seasonable assistance during my ten years' conflict with this affair; also Dr. W. B. Scott, and Dr. M. S. Farr, of Princeton, for help in correcting the press. And I cannot but confess my sense of thankfulness to God, who has spared my health, and given me opportunities of laboring in a very interesting bit of scientific work. Whilst not attempting to revise the Cryptogams, I have the satisfaction of referring for them to the fine reports of the Swedish Southern Exploring Expedition (1901-1903) which include the botany of Fuegia, of the Falk- land Isles, of South Georgia, Kerguelen Land, and the South Polar regions as far as investigated ; all carefully illustrated. Carl Skottsberg's reports (in German) correlate their Phanerogamic botany ; others give us the algology, and their Bryological Flora (in French, by Jules Chardot). This fine book reinforces arguments from other sources, in favor of the theory that there was a land-connection, in early geological times, between South America, New Zealand, Kerguelen, Tasmania, and South Georgia, as well as South Shetland Isles, to which Amundsen's discoveries now enable us to add Antarctica, with its polar-Andine mountain chain. Both Skottsberg and Chardot emphasize the service rendered by Dusen in these questions ; through his work on the Mosses of Patagonia and Fuegia, we now know of at least 150 additional species in those countries, half of them new to science ; and now the Magellan mosses number 444 species ; MACLOSKIE I REVISION OF FLORA PATAGONICA. 3 to be in all probability 500 species, so soon as those collected by Darwin during the voyage of he "Beagle" (in 1836) and more recently by Hatcher, shall find men to examine and name them. Chardot also informs us that 79 species of mosses are common to Magellan and New Zealand ; 60 common to Magellan and Tasmania; and Skottsberg finds 43 species common to Magellan and the small island of Kerguelen. All these figures become significant and interesting when regarded as evidence of prehistoric connection of lands which are now widely separated. Our knowledge of the Sedges, and also of the Hooked Sedges (Unciniae), of the Southern lands, has been advanced by the valuable contribution of Kiikenthal in Engler's Pflanzenreich ; and I have endeavored to utilize this help.

Add the following: H. RARUM R. Br. — Macl., p. 130. The occurrence of this species in S. America appears to be somewhat doubtful. H. rarum is omitted in The Reports of the French Cape Horn Expedition, and has been found neither by Skottsberg, nor by Spegazzini and Dusen. The S. American plant hitherto stated to belong to H. rarum represents, according to Christiansen, some forms of 21, Hymcno- phyllum ctmeatum Kee, Anal, pterid., p. 50, which consequently should replace H. rarum R. Br. 8 PATAGONIAN EXPEDITIONS I BOTANY. H. cuneatum Kee seems to be a rather rare plant in this district, found by Skottsberg in W. Patagonia at Puerto Olale by Golfo de Penas, cer- tainly no other locality of this species being known from the district we have in sight. Whether the specimens brought home from S. Fuegia by J. D. Hooker, and stated by him to represent a variety of H. rarum R. Br. belong, in fact, to that species may, at present, be an open question. H. CUNEATUS Kee is found also in S. Chili, Chiloe, and in Juan Fernandez. It may also be mentioned that H. PELTATUM Poir. Desv. — Macl., p. 130 (H. peltatum Poir) (syn. H. Wilsoni Hook.) is by C. Christiansen separated from H . falklandicum Bak. He emphasizes, however, the close affinity between these species. (C. Christ., Some Ferns, p. 25.)

Add Macl., p. 133 : B. AUSTRALE L. forma GENUINA (Hicken). According to C. Christ. Ind. Fil., B. australe and B. auriculatum Cav. (syn. B. hastatum Kaulf.) are separate species. Mr. Hicken, in his paper "Quelques Fougeres Argentines," declares that the character considered to be, above others, of specific importance, viz., the position of the sori, is very varying. The sori have now a marginal position, again they are disposed along the middle nerve, but often enough they have an inter- mediate position. According to Mr. Hicken, B. australe, B. auricnlatum and B. trilobum Presl are all varieties of one species. These varieties are named genuinum, hastatum and trilobum. Only the first of these, char- acterized by the position of the sori, being close to the middle nerve, belongs to our district. Having examined numerous specimens of B. australe and B. auricu- latum preserved in the Ricksmuseum in Stockholm I arrived at the opinion that of the varieties set up by Mr. Hicken at least var. genuinum and var. hastatum represent only extreme forms.

Note. — Philippi has described Lycopodium chonoticum from the Chonos Archipelago — see Linnaea, Bd. 29, p. 108 — and compared it with Lyco- podium paniculatum Remy. Philippi's diagnosis is short and agrees well with the description of L. paniculatum with the exception of the number of spikes which are geminate in L. chonoticum. Philippi's species repre- sents, perhaps, only a variety of L. paniculatum. Having seen no specimen of L. chonoticum I prefer to draw attention to the possible occurrence of L. selago L. a species or variety of a species of Lycopodium in our district. (P. D.) Lycopodium selago is northern, especially European, an isophyte, rejoicing in temperate climates, and surroundings. Some of its varieties are subantarctic ; the L. selago var.

I am not so fortunate as to have at hand the paper of Stapf entitled "Die Arten der Gattung Ephedra." But I may add, E. amencana var. Humboldtii, as already inserted; see supra. Also E. nana Dus. should be added. In 1908 Dr. Stapf informed me that E. nana is probably identical with E. americana var. rupestris ; but recently Dr. Skottsberg has informed me that Dr. Stapf has changed his opinion and is now inclined to accept E. nana as an independent species.

The present species is not very much akin to the American species of the same genus, but stands close to Stipa sibirica Lam. The last differs from S. hirtiflora by longer, broader, usually plane, scabrous leaves, by denser panicle richer in flowers and with 3-5 rays at the nodes of the rachis, by 3-nerved empty glumes, about 8 mm. long and floral glumes of the same length and by awn being glabrous or at the most scabrous- puberulous at the base, but never covered with long hairs.

There is, in fact, very little difference between A. alpinus Sm. and A. antarcticus Vahl, as E. Hackel informs me. The last mentioned usually is higher ( i m. or still more) and has much longer awn than the former. Its spike varies in length and thickness and the color of the glumes is also varying. The A. alpinus itself sometimes attains a considerable height. The only character of any importance separating them is the much longer awn of the glumes in A. antarcticus. This difference, how- ever, scarcely gives sufficient reason for separating them specifically. A. antarcticus, therefore, may be placed as a variety of A. alpinus. 34 PATAGONIAN EXPEDITIONS: BOTANY. Add Macl., p. 179: A. ALPINUS Sm. var. ANTARCTICUS (Vahl) f. LECHLERI (Steud.). Syn. Alopeciirus Lechleri Steud. Syn. Glum., I, p. 148. It is, in my opinion, impossible to separate, at least specifically, A. Lechleri Steud. and A. alpinus Sm. I have had the opportunity of examining two specimens of the first mentioned collected at Valdivia or not far from there. The one has the upper part of the culm naked ; in the other the culm is sheathed quite up to the spike. Other differences do not exist. Both specimens are characterized by narrow, subconvolute and subpungent upper leaves and very small spike. The same form was observed by me in the beech forests by Lago Argentine, Lago Viedma and Lago San Martin and probably occurs in the whole district of A. alpinus var. antarcticus. The two specimens now in question belong to the collection of Chilian plants made by W. Lechler and distributed by R. F. Hohenacker. The one (No. 440) is determined as A. Lechleri Steud., while the other (No. 532) is labelled A. alpinus Sm. They represent, however, evidently only one form standing very near to A. alpinus var. antarcticus and differing merely by its comparatively small spike and upper leaves being subcon- volute, subpungent and narrower than in the var. of A. alpinus Sm. In my opinion the present plant represents only a form of A. alpinus var. antarcticus; it occurs in the forest district of S. Chili and probably of the whole of W. Patagonia, but scarcely outside the forest. D. Add Macl., p. 179: ALOPECURUS FULVUS Sm.

In my explanation of the Fuegian and Magellan vegetation, "Die Gefass- pflanzen der Magellanslander," I have brought together A. alpinus Sm. and A. antarcticus Vahl., under the name of A. alpinus, but for this there MACLOSKIE: REVISION OF FLORA PATAGONICA. 35 was, in fact, no very good reason. The specific name antarcticus is older than alpinus, and, besides this, there is really a certain small difference between these two, the awns being much larger in A. antarcticus than in A. alpimis. I therefore think it will be more correct to note the latter as a variety of the former. Macloskie separates them, and also names A. antarcticus var. alpinus (A. alpinus Sm.) ; but A. antarcticus var. alpinus (A. alpinus Sm.) is an arctic plant and not known from S. America, and should therefore be eliminated from his explanation. D. Yesterday when visiting (June 30, 1913) Upsala I called Skottsberg's attention to his opinion about Alopecurus fuhus, geniculatus, and alpi- nus, but he ultimately expressed himself as agreeing with what I had written. D. Alopecurus antarcticus Vahl. (Macl., p. 179) is the right name, A. magellanicus and A. alpinus v. aristatus Hook. fil. being synonyms. Alopecurus Lechleri Steud.

A. flavidula Steud. A. aberrans and A. flavidula are represented by one specimen each in Herbarium Stockholmiense emanating from W. Lechler Plantce Magel- lanicce in which collection A. aberrans is numbered 1219 and A . flavidula 1225, the very same numbers referred to in Steudel's description of the species — Steud. Syn. Glum., I, pp. 421 and 422. Both species have the same habit, which induced me to examine them more closely. The specimen of A. flavidula is a couple of straw-colored individuals, evidently taken at the close of the vegetating season. That of A. aberrans is a single one, in size and proportions analogous to the former, but with fully open blades, whilst those of A.flavidula are conduplicate. In addi- tion there are two panicles of the very considerable length of 16 cm., the same size that is given in the description. A. flavidula, Steudel says, has "valvula solitaria." This does not tally with the specimen examined by me, which must be taken to represent Steudel's species. All flowers examined by me had a rounded, diminu- tive palea (valvula superior). In Steudel's description of A. aberrans there is the following very inex- plicit clause : "valvulis subaequalibus . . . (quandoque exteriore abbrevi- ata)." My examination, however, of the specimen in question shows the MACLOSKIE : REVISION OF FLORA PATAGONICA. 37 flowers to be entirely like those of A. flavidula, and the floral glume papilliferous. In other respects, apart from their size, I have not been able to see any difference between the two species and, therefore, consider them identical. Both were published at the same time. Flavidula, for obvious reasons not being a proper denomination, I deem it better to adopt aberrans as the specific name. It may be questioned whether A. Kufuim Speg. should not also be merged in A. aberrans. Having had no chance of examining any speci- men, and the description of the first named, in some particulars, not quite agreeing with A. aberrans, A. Kufuim, I think, at least at present, should be allowed to retain its position as an independent species. Spegazzini collates A. Kufuim with A. montemdensis Spr., while A. aberrans rather reminds of A. umbellata Colla. In this connection I wish to draw attention to an error in my previous work "Die Gefasspflanzen der Magellanslander." On page 219, A. Kufuim is said to occur in Magellan and Fuegia, but this applies rather to A. aberrans. D. A. ANTARCTICA Hook. fil. — Macl., p. 185. Should be deleted, being identical with A. magellanica Lam. A.

My reference is to this paper of Murbeck, unfortunately written in Swedish. I quote the complete synonymy of Murbeck," as to this species. In his dissertation " North American Species of Agrostis," A. S. Hitchcock, from the single specimen in Linne's Herbarium of A. stolon- ifera (which, according to a note in Linne's own handwriting, was found 42 PATAGONIAN EXPEDITIONS ! BOTANY. in Attica), concludes that this species does not belong to the North Euro- pean flora, but is indigenous in the warmer parts of the old and new world. In Linne's Flora Suecica, however, A. stolonifera is given as common, and in his Species Plantarum there is appended to its name the somewhat inexplicit note "in nemoribus." Possibly Linne's A. stolon- ifera includes two species ; but be this as it may, it can be safely presumed that the species from the Falkland Islands here referred to, namely, A. stolonifera is identical with the Scandinavian form and not with that South European form or species to which Hitchcock would confine the name A. stolonifera. This species having a very limited range in peraustral South America, being, in fact, found only in the Falkland Islands and, in all likelihood there confined to the vicinity of Port Stanley, must in all probability have been introduced.

From not a few localities in Fuegia, as well as southern and western Patagonia, I have brought back specimens of this species, and the materia, thus collected was defined by Professor E. Hackel. Later on, that Swedish expert in North-European Calamagrostides, Dr. S. Almquist has, likewise, examined the same specimens and arrived at the same results as Hackel. Almquist, however, goes a step farther than Hackel, inasmuch as he divides the material into two groups, of which the one comprising the majority of specimens is characterized by the culm being compara- tively thick and robust, thereby differing from the typical C. neglecta. According to Almquist this form should be taken to be a subantarctic breed of the present species. To the other group belong the specimens collected at Rio Aysen in W. Patagonia. These also have a very robust culm, but show a more marked difference from the type by their longer and denser, slightly nodding panicles, which are sometimes discontinued at the base. These latter Almquist takes as a subspecies of C. neglecta. That also E. Hackel has noticed the greater discrepancy of the speci- mens from the Rio Aysen valley, is evident by a note by him on the label attached: "An C. poceoides Steud.?" and this presumption is, naturally, supposed by Steudel's description of his species. Whether, in fact, the specimens in question are identical with C. poceoides, cannot be decided without a comparison with an authentic specimen of that species. Until this point shall have been settled, I think, the baptism of the subspecies might be deferred. By the examination of the material referred to, it has been conclusively 44 PATAGONIAN EXPEDITIONS: BOTANY. proved that another of the North European grasses is to be added to the "pretty many" previously known which, in a typical or modified form, recur in the peraustral parts of S.

Fr. of Macl, p. 195, should be changed into this genus Aira (olim Airopsis, nunc Aira). Airaflexuosa L., added by Macl., is identical with Deschampsia flexuosa, and should, in my opinion, be deleted. D. A. ATROPURPUREA Wahlb. — Macl., p. 198. Some time ago I stated that the figure of this species given in Flor. dus. (sub A. magellanica] agrees exactly with specimens of the same species preserved in the Stockholm Herbarium. I have also expressed the view that this species, in fact, must be transferred to the genus Des- champsia, in accordance with the exposition of the Gramineae in Engler and Prantl Nat. Pflanzen-familien ; viz. its subgenus Vahlodea as already noted in that work. I have not, however, made such a transfer, as that will involve too many changes to be attempted at this time. Descltampsia antarctica is by Skottsberg transferred to Aira. I have carefully ex- amined the species and think it is undoubtedly a Deschampsia. But as a new systematic arrangement of the Grasses is probably coming, we can- not discuss these equations at present. D. Macloskie has, according to Desvaux in Flor. Chil., VI, p. 340, put down Aira magellanica Hook. fil. as synonymous with the present species, to which there is no reasonable objection to be made. Though I have not seen a specimen of A. magellanica, J. D. Hooker's reproduction of it in Flora Antarctica, II, Tab. 134, appears to be identical with Aira atropurpurea. D. Add Macl., p. 198: A.

SUPERBIENS Steud. — Macl., p. 198. Being synonymous with Poa fuegiana (Hook, fil.) Hack, (of p. 227) this species should be left out 46 PATAGONIAN EXPEDITIONS: BOTANY. There is not the slightest doubt of the identity of A. superbiens and Poa fuegiana. I have examined a specimen of the former, which is num- bered 1194 in W. Lechler's Plantce Magellanicce and I find it to be iden- tical with the latter. Add Macl., p. 199 : AIRA ELATIOR Steud. ( = Deschampsia Kingii}. Root stout, cespitiferous.

A. vestita has No. 1193 in the above collection of Magellan plants by W. Lechler. The specimen I have examined agrees with Deschampsia flexuosa, at least it approaches its variety or, properly speaking, form montana (L.). DESCHAMPSIA Beauv. D. ACIPHYLLA (Franch.) Speg. — Macl., p. 200. Has a far wider distribution than stated by Macloskie. In addition to Fuegia and the Magellan Territory, it is also found in W. and N. Pata- gonia. Here should, probably, be placed Deschampsia tenella Phil, as a variety of D. aciphylla. According to Spegazzini — cf. Speg. Add. Flor. MACLOSKIE: REVISION OF FLORA PATAGONICA. 47 Patag., Ill, p. 193 — the difference between them is of no great impor- tance. Having had no opportunity of examining any specimens of D. tenella, it seems to me to be more convenient to let it remain, for the present, as an independent species, as stated by Macl., p. 203.

The species extends considerably further north than stated by Maclos- kie as I have, myself, found it to be common at fresh-water lagoons in the Sta. Cruz Territory, and Spegazzini notes it from N. Patagonia. D. D. FLEXUOSA (L.) Trin. — Macl., p. 201. Syn. Aim vestita Steud. The range of the species is more extensive than that given by Macloskie. It is rather common in the western part of the Sta. Cruz Territory in the lowlands as well as in the mountain slopes, up to an altitude of 700 m., and occurs not less frequently in the upper part of the Rio Aysen valley from its foot up to 800 m. In open ground it scarcely attains the height of 3 dm., in the forest one to two dm. more. D. D. GRANDIFLORA NeCS. -- Macl., p. 2OI. Steud. Syn Glum., I, p. 220 (sub Aim}.

Trisetum Dozei, according to Franchet in Miss. Cap Horn., V, p. 385, is only a robust form of Aira elatior, and might, consequently, be placed as synonymous with the present species. DESCHAMPSIA PULCHRA Nees et Mey. — Macl., p. 203. Any confirmation of Macloskie's statement of the occurrence of this species in Patagonia I cannot find, and it should, therefore, be withdrawn. According to Desvaux in Flor. Chil., VI, p. 336, and Steudel in his work, Syn. Glum., I, p. 220 (sub Aira), it belongs to Chili. D. Page 203 : Deschampsia tenella Phil.

In my copy of Speg. Plant. Pat. Austr. Spegazzini has left the following mar- ginal note by Cryptochloris spathacea : "Elymus Kurtzii Speg.!" In this he informs us that the determination, Cryptochloris spathacea, is wrong; and the plant is identical with E. Kurtzii. Cf. F. Kurtz, Collectanea ad Flor. Argent., p. 259, "Cryptochloris spathacea Speg. dans Rev. Fac. Agron. y Vet . . . est Elymus Spegaz- zinii mihi, espece tres voisine (si non identique?) de 1' E. erianthus Phil.' In 1908 Hackel informed me that Elymus Spegazzinii really is synony- mous with E. erianthus Phil, this name being older than E. Spegazzinii. Hence we must delete Tetrapogon spathaceus Benth., without substitut- ing anything, as the question is still unsettled. D. Macl., p. 212, insert, 5 lines from foot: PHRAGMITIS DIOICA Hack.

Hordeum secalinum Schreb. was published 1771 and Hordeum pratense Huds. 1778 in the second edition of Hudson, Flora Anglica (not in the i st edition of 1 762). Hordeum nodosum L. was published in 1 762 in the 2d edition of Species Plantarum and is, according to Ascherson and Graebner, a quite doubtful plant. There is no Hordeum secalinum L. Macloskie's exposition of this genus contains many species and varie- ties which must be deleted, viz., H. chilense Brongn. (Macl., p. 249; H. pratense Huds., Macl., p. 250). This species was published not in 1762 (ist ed. of Hudson's Flora Anglica), but in 1778 (2d ed. of that work). Macloskie also states that H. secalinum L. of 1771 is synonymous with H. pratense Huds.; but there is no H. secalinum of L., and Macloskie must refer to H. secalinum of Schreb., which was published in 1771. H. nodosum L. of 1 762 is according to Ascherson & Graebner, in their Flora of Central Europe, quite a doubtful plant. Hence it is certain that H. pratense Huds. (of Macl., p. 250) must be replaced by H. secalinum Schreb. D. Macloskie also mentions H. pratense as occurring in N. Patagonia, a statement apparently based on the Rio Negro Report, which refers to a form very near to H. secalinum as occurring near Rio Negro. In har- mony with this we would replace the Hordeum pratense chilense Desv. (E. Fuegia, Dusen), Macl., p. 251, by H. secalinum Schreb. var. chilense (Brongn.) Desv., as the same name appears in Dusen's Gefasspfl. Magell., p. 233, and emanated from Hackel, who determined his specimens. Macloskie's statement that H. pratense Huds. (that is, H. secalinum Schreb.) occurs in Patagonia is erroneous. Thus far it is not known from any part of the district, but its var. chilense is reported from Pata- gonia and from Fuegia by all the botanists who have reported on the flora of the steppe district. Hence there can be no question but that H. pratense Huds. must be replaced by H. secalinum Schreb. var. chilense (Brongn.) Desv. The above mode of writing indicates that it was Des- vaux who gave H, chilense of Brongn. its place as a variety of H. secalinum Schreb. D. As to Hordeum pratense Brongniartii (Macl., p. 251) and H. pratense chilense Desv. (p. 251), a comparison of Macloskie's descriptions of these varieties demonstrates their identity. Besides this the description of Hor- 66 PATAGONIAN EXPEDITIONS : BOTANY. deum pratense Brongniartii (Wad.., p. 251) is a complete verbal translation of H. secalinum Schreb. var. chilense (Brongn.) Desv., as given by Des- vaux in Gay, Flor. Chil., VI, p. 458. Also by oversight Macloskie gives one and the same plant, viz., H. secalinum var. chilense (Speg., Prim. Flor. Chub., p. 630, in collibus siccioribus) as belonging both to Hordeum chilense Brongn. and to H. pratense Brongniartii Macl. Hence we must delete from Macloskie's list H. pratense, H. chilense, H. pratense Brongniartii and H. pratense chilense, deleting the first of these, and absorbing the other three in H. secalinum var. chilense (Brongn.) Desv. This occurs in E. Fuegia ; Patagonia, in the steppe from its north- ernmost to its southernmost section ; hitherto, however, not known from the coast-district. D. Add Macl., p. 254 : ELYMUS L.

Taking the term Sedges in its wide sense, as including the Uncinia or Hooked-Sedges, and the Carices, or Hookless Sedges, Kukenthal Pflanzreich IV, 20, 1909), compares them with the World of Grasses noting that they differ from Grasses in having the culms not cylindrical, 68 PATAGONIAN EXPEDITIONS : BOTANY. and not hollow and jointed, but triangular, solid and jointless ; and that in the seed the minute embryo is enclosed in the endosperm at its base, the seed being itself enclosed in the lodicule, whilst the embryo of Grasses remains external to the endosperm, the leaves being in 2 rows in the Grasses and 3-ranked in the Cyperaceae. Kiikenthal divides the Sedge-like plants into a large number of chief sections, distinguished partly by structure and partly by habitat; and groups all the leading species within a comparatively small number of genera: the chief genera being Uncinia, or Hooked Sedges, which are chiefly characteristic of the Southern Hemisphere, and Carex, which is cosmopolitan. In the first half of the Caricoideae, we encounter three genera, Schcenoziphium, Cobresia, Uncinia, and in the latter half the only genus is Carex. The first of the genera, which we may call No. i is confined to Africa, and characterized by very simple monoecious flowers. The next genus, No. 2, is Cobresia Willd., containing numerous species in the Asiatic alps, and two species found in the Arctic and alpine parts of Europe, and in the Canadian mountains. They form four sections of genus Cobresia. Our next type is the genus Uncinia Pers., having two subgenera, and two sections of the first subgenus, thus named. Genus Uncinia, with hooked rachil ; No. 7. Subgenus Eu- Uncinia, rachil long-hooked ; No. 8. Subgenus having two sections. Section i, Platyandrae, filaments dilated; No. 9. Section 2, Stenandrae, filaments filiform, not dilated ; No. 10. Subgenus Pseudocarex Kiikenth., rachil with very short hook; No. ii. Lastly we have the type, Genus Carex L., No. 12, usually with no rachil, and never with a hook. UNCINIA Pers. — Macl., p. 268. The appearance of Kiikenthal's treatise on Cyperaceae-Caricoideae enables us to improve our treatment of the Patagonian sedges. As the only dif- ference between Uncinia and Carex appears to be that in all the Unciniae the seta is hooked at the apex, whilst it is never hooked in Carex ; we may distinguish them as the Hooked Sedges and the True Sedges. Kiikenthal gives the Uncinia kingii Boott a place by itself, because its MACLOSKIE: REVISION OF FLORA PATAGONICA. 69 hook is very small, thus setting it up as the type of the subgenus Psettdo- carex. The other sections (together making Eu-Uncinid] are Platyandrte, with dilated filaments, and Stenandrce, with filiform filaments, and smooth utricles. All the 21 species of Uncinia are found in the Southern Hemisphere, in the Antarctic Islands, Australia, Tasmania, New Zealand, in the moun- tains of South America; with stragglers northwards as far as Jamaica and the Sandwich Islands. And a few species occur in Chili, Patagonia, Fuegia and the Falkland Is. In the Patagonian flora, we have — a. SPECIES OF PLATYANDR^E. UNCINIA BREVICAULIS Thou. Add Macl., p. 269. Rhizome long.

Rachil very shortly hooked. Only species of this subgenus. Magellan ; Port Famine ; Fuegia. U. microglochin belongs to Carex because ofitshooklessunjointed seta. It is Carex microglochin Wahlenb. Its prevailing Arctic distribution favors the same conclusion. NOTE ON THE GENUS CAREX, SEDGE. Carex contains about 800 existing species, scattered over the world ; and also remains of many more fossil species. The one great genus is arranged by Kiikenthal under four subgenera, and 69 sections, including numerous subsections, each of which stands for an array of species, closely allied to each other. For the Patagonian species our most convenient method is to attend especially to such of the sections and subsections as are represented in the flora of that region ; and thus to confine our attention to this part of the large Sedge Family ; and the sections and other groups are numbered for convenience of reference.

The proper province of this species is the tropical parts of the Old and New World, but, in the latter it extends into its subtropical section, and, in S. America, reaches Paraguay and, probably, also the subtropical part of Argentina. At high floods in the River Plate basin it is, not seldom, carried down its estuary, but it is only as an occasional visitor it appears in the latitude of Buenos Aires and La Plata. It certainly does not belong to the flora of S. Argentina, and still less to that of Patagonia. There is, therefore, not the slightest doubt that it should have no place in a representation of the flora of our district. MACLOSKIE: REVISION OF FLORA PATAGONICA. 85 Fam. 13. LEMNACE^:. Duckweed.

Scheuchzeriodes Gaud., agreeing with the variety inconspicuus (d'Urv.) Gaud, of that species. (See above under y. depauperatus Phil.) The distribution of this variety is, according to Skottsberg; Falkland, Fuegia, S. Georgia, Campbell I. J. LESEURII Bol. — Macl., p. 299. Also in NW. Patagonia, Rio Manso ; W. Patagonia, Rio Aysen. J. MARITIMUS Lam. — Macl., p. 299. According to Buchenau, in Pflanzenreich, June., p. 154, this species, S.

Any other statement of its occurrence there than Macloskie' s on page 299, I have not seen ; the specimens referred to by Macloskie were collected by Hatcher, no doubt in S. Patagonia. I have not seen them MACLOSKIE : REVISION OF FLORA PATAGONICA. 89 and, therefore, can give no definite opinion on their systematic place, but nevertheless, may be allowed to express a slight doubt of the correctness of Macloskie's determination.

Not in our district. In " Die Gefasspflanzen der Magellanslander " I have given this species from Buchenau's determination as indigenous to Fuegia. In Pflanzen- reich June., p. 75, it is not stated to occur in our district, evidently because the determination has turned out to be incorrect. My own exami- nation of the specimens has shown that, without doubt, they belong to L. chilensis. From typical specimens, however, they differ, as previously pointed out, in having more remotely attached spikelets. D. L. SPICATA DC. — Macl., p. 303.

ORCHIDACE.E. — Macl., p. 320. In Engler und Prantl, Die natiirlichen Pflanzenfamilien, the genus Asarca is not separated from the genus Cklorcea, nor is it in Macloskie's representation of the present family. One of the most modern works on orchids is that by Fr. Kraenzlin, entitled " Orchidacearum genera et species," the vol. II, pars I (1904), of which contains the Chlorideae. Here we find Asarca separated from Chlorcza. The following enumera- tion of the species of our district is based on that work. ASARCA Lindl. Kraenzlin distinguishes this genus by ( i ) the union of the lateral sepals below or behind the labellum ; (2) a very short column united with the claw of the labellum ; (3) two fruiting glands at the base of the labellum ; (4) the hollowed claw of the labellum, resembling a gland. A. ARAUCANA Phil. Stem 50 cm. long, leafy half-way ; 'lower leaves sheathing, linear lance- olate, acute; cauline leaves more swollen.

The type in Herb. Holm. QUINCHAMALIUM Juss.— Macl., p. 342. The species of this genus are in need of a thorough revision, but on account of want of material I have not been able to undertake it. I should not omit pointing out, though, that, according to A. B. Rendle, the species occurring in the vicinity of Lago Argentine— as far as I am aware there is only one found there — is identical with Quinchamalium procumbens Ruiz et Pav., which Rendle considers to be, in all probability, the same as Q. chilense Lam. On the other hand, it is doubtful whether Lamarck's species is identical with Q. chilense Lam. The last species is very unsatisfactorily described, and, according to Philippi Cat. Plant. Chil., it includes all the species of this genus. Rendle further observes, in Journal of Botany, Vol. 42, p. 327, that the specimen of Q. dombeyi Brongn. of the British Museum agrees with Q. procumbens Ruiz et Pav. From this it appears certain that a revision of this genus should result in a very considerable reduction of the number of species. D. Fam. 31. POLYGON ACE^:.— Macl., p. 348. RUMEX L. R.

The descriptions of both species agree IO8 PATAGONIAN EXPEDITIONS: BOTANY. very well, except in one particular. According to O. Kuntze, the inner perianth-leaves of ft. crispissimns have a globose callus. This is not the case with R. decumbens, although its inner perianth-leaves really are pro- vided with callus-like swellings ; but they consist of a loose, pulpose texture with pretty large and air-filled cells. With that exception, both descriptions agree and it, therefore, appears to me as if O. Kuntze, some- what hastily, had assumed the swellings of the perianth-leaves to be callus-formations, and had not taken the trouble to ascertain if they actually were such. (Dusen.) Spegazzini and Skottsberg unite both species into one. P. 349: Delete R. decumbens Dus.; syn. of R. crispissimus. R. de- cumbens Dusen occurs also in a valley by Rio Pelque (Dusen).

The following summary of the Patagonian species of this genus is based on the recent paper of Reno Muschler, in Engler's Botan. Jahrb., Bd. 21, p. in. Note by Macloskie. — Muschler's revision collects into one genus, Coro- nopus (L.) Gaertn. about 45 species, of all countries, hitherto scattered among half a dozen different genera ; all of them short-fruited, and with the characters of Coronopus as in Macl., p. 427, to which some negative characters may be added ; that the fruits are not pendulous, nor winged, MACLOSKIE : REVISION OF FLORA PATAGONICA. 1 29 rarely cuneate at base ; the style is short, often very short, and the reticu- lation of the seeds almost obsolete. The illustrations given furnish the differences of fruit and of floral plan on which the order is broken up into sections. Muschler boils down the 45 species of several genera into ten species of a single genus ; with however a subgenus, and three sections, and other subspecies, and varieties, and "forms." Each of his species is not a unit, but a combination of units, as he declares. This course appears to us to be practically convenient, rather than theoretically scien- tific; to be a striking instance of the pragmatistic method of dealing with a troublesome case. His first section, Carara DC, has subreniform sili- cules, with thick, conical style, the valves reticulate-rugose all round, and marginally toothed. Species verrucarius and violaceus, spreading through the Old World ; and one of the varieties (C. verrucarius procumbens; syn. C. Ruellii All.) reaches America as far as Chili, as an immigrant. (Probably my citation of it as found in Patagonia was an error: Muschler observes that though Dusen collected in the same location as Hatcher, he did not find this species.) The second of Muschler's sections, Nasturtiolum DC. has the silicic dehiscing into 2 cocci, its stigma is a third as long as the septum, or none ; only 4 glands on the receptacle, and these are mere rudiments. This section Nasturtiohim has 3 species, of which C. integrifolius is African, extending to the Orient ; and C. englerianus Muschl. is confined to East Africa or Mozambique. And the third species C. didymus (L.) Sm., is unique both in its reduction of parts and in its cosmopolitan distribution. It is found in North and South America, and in Europe and Africa, and even in Australia. Muschler regards it as an antique form, which orig- inated in South America, and has spread thence over all the continents. On the other hand, he regards integrifolium as having tropical Africa as its fatherland, whilst he seems to think that C. englerianus was born in the Lake District of Eastern Africa. C. didymus (L.) Sm., is represented by him as originating in our Patagonian area, and having migrated thence to other parts of America, and as now spreading over the world. It may have no petals, and mostly has only 2 stamens ; and the fewness ot its seeds is counterbalanced by the abundance of its flowers. The section Cotyliscus (Desv. pro gen.) DC. has two species, both of them African, easily recognizable by the convex-concave silicic. The last section, Delpinoella (Speg.) Muschl. was introduced by Spegaz- 1 30 PATAGONIAN EXPEDITIONS : BOTANY. zini, as a southern South American genus, and is described in Macl., p. 427. Its silicic is cordate, and its sepals persisting, and its valves foveo- late, or pitted, and stigma capitate. Of its three species, one, C. serratus, belongs to Brazil, the other two, C. patagonicus (Speg.) Muschl., and C. rhytidocarpus (Hook.) Macl., are Patagonian. — Hactenus G. M. CORONOPUS DIDYMUS (L.)

P. 429 (No. 3) : The authority of Thlaspi magellanicum is Commerson (1806). (Persoon gave the same name in 1807.) Add Macl., p. 429: T. ANDICOLA Hook. & Arn. Note. — Reiche in his Flora de Chile, 1. 169, gives T. andicola as an independent species. Gilg & Muschler are of the same opinion. Skotts- berg (Engler's Bot. Jahrb., Bd. 42, p. 452) regards T. andicola as iden- tical with T. magellanicum. (See Skottsberg, zur Flora des Feuerlandes, p. 18; Wissenschaftliche Ergebnisse der Schwedischen Siidpolarexpedi- tion 1901-1903, 4 Lief. 4.) Dusen regards this opinion as well-founded, and consequently accepts Skottsberg' s arrangement. Common in the Fuegian and Patagonian steppes, especially in the remote southern and western sections ; also in the mountains of Western Patagonia, as in the upper valley of Rio Aysen, about 1,200 m. at Arroyo Scheuen.

Gilg and Muschler hold that the true Braya does not occur in South America ; but some new Eudemas are there, whose characters tend towards a new group, Brayopsis, like Braya, yet different. Eudema is one of the S. American genera. It contains casspitose herbs with small linear or spathulate leaves, subequal spreading sepals, and ses- sile ovary, filiform style and capitate stigma. Silicic ovate-oblong, obtuse, compressed parallel to the fenestrate dissepiment; the valves 5-12 seeded. Gilg and Muschler refer to it, or to Brayopsis, or Englerocharis, or Weberhauera, most of the South American species formerly placed in Braya, Sisymbrium and Draba.

W. Patagonia, near Lago Buenos Aires. (Leg. J. Koslowsky.) This species resembles as to its vegetative system A. multifida Hook, fil. and A. pinnatifida Ruiz et Pav., but differs from these in the globose terminate head of flowers rather distantly separated from the nearest few flowers in the axil of the uppermost cauline leaflet. From all hitherto known Accence, this species is separated by the winged seeds. By this characteristic our species deserves to be ranged as the type of a new section. 152 PATAGONIAN EXPEDITIONS: BOTANY. The fruits — it may be remarked — were not quite ripe. During my stay in S. Patagonia, 1905, I found at several localities in the steppe between Sta. Cruz (Emporium) and Lago Argentine an Accena with ripe fruits, the plant being unknown to me. The seeds were winged, as in A. pterocarpa, but the wings were not so pointed, but more trun- cated than In the above species ; they were armed with small retropacted spines as in A. pterocarpa. The seeds brought home were sowed and germinated, but the plants were, when I started for S. Brazil, far from being in bloom. I may, there- fore, not be able to state that the family plant found in the steppe of S. Patagonia is, as I am supposing, identical with the species here described.

It stands near to L. magellanicus Lam. var. oxyphyllus Speg., dif- fering from that variety in much smaller and semisagittal stipules, shorter and patent leaflets and larger flowers. P. 529 : L. MARITIMUS Big. Occurs also on the Guaitecas Islands and on the opposite coast of the continent. L. NERVOSUS Lam. Not rare in the southern and middle section of the steppe, especially near the forest district, sometimes abundant.

Should be struck out ; the determination refers to V.patagonica Hook. fil. P. 530 : L. PUBESCENS Hook, et Arn. According to Spegazzini this species is not rare through all Patagonia. There is, probably, some exaggeration in this statement. In the year 1905 I crossed S. Patagonia from the mouth of Rio Sta.

This species stands nearest to Moschopsis leyboldi Phil., which differs from the present in longer, elongate-spathulate, acute leaves. As to its habit, this' species reminds us of Acicarpha rosulata N. E. Brown. It is, however, less robust, having more rounded leaves, being entire or only laterally, never terminally, serrated.

Chil., iv., p. 258, has described the plant as an independent species, but with the remark, "perhaps iden- tical with S. danyausii Homb. & Jacq." In my opinion we have to do only with a form of that species (see Macl., p. 842) being, as to its leaves, a very variable plant. D. P. 852 : S. LONGIPES Hook. fil. This has synonyms : Senecio dumosus Phil. S. arnotti Hook. f. Senecio ibari Phil. S. crithmoides. Senecio nordenskjoldii O. Hoffm. S. limbardioides H. & A. 274 PATAGONIAN EXPEDITIONS: BOTANY. Senecio fuegianus Phil. S. tricuspidatus H. & A. Senecio mscoides Reiche. S. viscoides Reiche. Senecio miser Hook, fil., var. tehuelches Speg. In South Fuegia ; Fuegian steppe, especially in the east coast ; Magel- lan; South Patagonia in the steppe as well as in the deciduous beech forests. A very variable plant as to its habit, size and denseness of the leaves, and degrees of its viscosity; the peduncles are always comparatively long (3-6 cm.) and i -headed, with rather large heads. The typical plant is a rather common steppe plant, about 2 dm. high, growing principally on or near the coasts. The leaves are entire or few-toothed, and a few mil- limeters broad ; the same specimen sometimes having entire as well as toothed leaves. The whole plant very viscous. Dusen writes: "Senecio viscoides Reiche from Magellan forms, in my opinion, only a variety of S. longipes. The same form was collected by myself at Sta. Cruz; it is much smaller in habit than the type, has decumbent branches, ascending at the extremities ; the leaves were toothed in the specimens collected by Reiche, and also in my specimens. The plant is resiniferous, much as the type. Another form which is taller, and more robust than the type, was collected by me in the interior of the territory of Sta. Cruz, as well as near the forest line not far from Lake Viedma. Its leaves were toothed, but narrower, and the heads somewhat greater than in the type. This form is no less viscous than the typical plant, and shows, in some respects, an intermediate position between the type and the following form. " The fourth form belongs to the deciduous beech forests, and is as common in their lower parts as in their heights ; it was found by me at least up to 950 m. " The height of this robust form varies from about 4 to 7 dm. Its leaves are somewhat broader and weaker than in the type, and entire or few- toothed even in the same specimen. The heads are somewhat larger than those of the type. At first sight it seems specifically distinct from S. longipes, through its obtuse habit and the apparent absence of resiniferous glands. A careful examination, however, shows that the glands are not lacking, but they are comparatively few. No other specific difference of character from S. longipes is visible. I therefore endorse Skottsberg's doctrine that they are not specifically distinct." S. crithmoides H. & A. is another synonym. MACLOSKIE: REVISION OF FLORA PATAGONICA. 275 P. 852 : S.

From Professor Macloskie I received a specimen of a Senecio collected by Hatcher in the Cordilleras of South Patagonia and determined by Prof. Dr. O. Hoffmann as 5. pachyphyllus Remy. Dr. Hoffmann had an opportunity to compare Hatcher's specimens with a specimen collected by Dr. R. A. Philippi and by him referred to S. pachyphyllus. My own specimens exactly agree with the specimen sent me by Prof. Macloskie. In order to determine my specimen I had at my disposal no authentic specimen of S. pachyphyllus, but only the diagnosis given by Remy in Gay, Flora Chil., vol. iv., p. 147. The leaves of S. pachyphyllus are there described as follows: "foliis crassissimo-cylindraceis . . . acutis," which does not agree with my plant, its leaves being quite plane, but somewhat fleshy, and hardly acute. And further, S. pachyphyllus is described as quite glabrous, while my plant (being for the most part glabrous) is pilose on the margins of the leaf-sheaths, and of the basal parts of the scape- leaves, as well as on the margins of the outer scales. I have therefore separated my plant from S. pachyphylhis. The two species, however, are near to each other. Is known from the eastern slopes of the cordilleras, and grows in open humid places, in South Patagonia, near Lago San Martin (250-500 m.), and in Mid-Patagonia near Lago Buenos Aires. D. P. 853 : S.

P. 864, line 3, insert: C. argentea Speg., whose synonym is Domophyton argenteum Speg. (of p. 866). Also C. spinosa Don. var. morenonis Ok. S. Patagonia, in the steppes by Rio Gallegos, Rio Sta. Cruz, Rio Chico, and near Puerto San Julian. D. According to F. Kurtz this species may be regarded as a variety of C. spinosa, as indicated above. Whether M. Spegazzini's view that it is an 280 PATAGONIAN EXPEDITIONS I BOTANY. independent species is preferable to the view of M. Kurtz I am not able to decide. On this question I offer no opinion. D. P. 864 : CHUQUIRAGA DUSENII O. Hoffm. Should be deleted, being identical with C. kingii. Spegazzini has erroneously united C. dusenii with C. argentea Speg., thinking that the former is only a variety of the latter. In Nov. Add. Flor. Patag., ii, p. 17, he writes "est forma robusta . . ., sed nullo modo a typo recedens; saepe in eodem caespite forma typica et forma dusenii simul inveniuntur." I presume that he does not know, or at least does not well know C. kingii. Writing this in an exploring excursion in South Brazil and not having any specimens at hand of the two species, I am, unfortunately, unable to note the strikingly different characteristics of the two species. I may say, however, that C. kingii is a robust, stiff shrub, about 8-10 dm. high; and C. argentea, on the other hand, is a much weaker shrub, generally about 2 dm. high. They occur also in different localities ; kingii is limited to North and East Patagonia, having its southern limits about S. lat. 44° ; argentea is, as already stated, limited to South Pata- gonia. D. P. 864 : C. ERINACEA Don. Macloskie states that this species occurs on the east coast of South Patagonia. This statement is undoubtedly incorrect, and is based on a mistake made by Spegazzini in Nov. Add. Flor. Patag., ii, p. 18, line 10, where C. erinacea Speg. (non Don) should be replaced by C. acicularis Don. (Plant. Patag. austr., no. 221, cited by Spegazzini refers by name to the last-mentioned species). Spegazzini makes another mistake in unit- ing C. hystrix Don with C. acicularis Don, two species which are well distinguished from each other. D. Skottsberg writes regarding this specimen: "I cannot get a better name for the species; but the specimen does not correspond with C. erinacea in all respects. The flowers are more numerous than in erinacea." P. 865 : C. HYSTRIX Don. Spegazzini's statement of the area of this species is naturally too wide because of his opinion that it is identical with C. acicularis. The present MACLOSKIE: REVISION OF FLORA PATAGONICA. 281 plant extends chiefly over northern and eastern Patagonia, being limited on the south by the 44th parallel. D. C. PATAGONICA Phil.

P. 887 : LEUCERIA, LASIORRHIZA. Where this group is treated as a single genus, the form Leuceria is often preferred. Bentham & Hooker distinguish Lasiorrhiza as a sub- genus, by the fact that its involucre is 2-3-seriate, as against 3~4-seriate ; and the receptacle has few pales in Leuceria. But these are not constant characters. Engler & Prantl regard Lasiorrhiza Lag. (Chabrea DC.) as a section under Leuceria, having a i-2-seriate involucre, and no chaff between the outer flowers on the receptacle. All the forms of both sec- tions have a plumose pappus, more or less long, and flowers never white. P. 888 : LASIORRHIZA ACHILLEIFOLIA (Hook. & Arn.) Syn. L. anthemidifolia (Phil.) Ok.

The specimens collected by Hatcher and labeled " head of Rio Chico " (p. 888) do not belong to this species, but to Lasiorrhiza hoffmanni Dus. I am inclined to suppose that some confusion has occurred concerning the locality, and that these specimens were actually got in the Cordilleras.

Better known under the name of Taraxacum officinale (Urth.) Wiggers. The present genus has in the last years, as well known, been matter of careful studies, and from these it was clear that the species established long ago — and thus also the old species now in view — were to be divided into a rather great number of new ones. Knowing specimens only from one of the districts mentioned by Macloskie it is impossible for me to state whether Macloskie's statement refers to a single or to several species. I am even not able to urge the species represented by the specimens collected by myself in Magellan. They belong very probably to a S. European species, as the eminent specialist of N. European, Arctic and S. American subantarctic species, Dr. H. Dahlstedt, has verbally informed me. This being the case, Taraxacum taraxacum should be struck out. Macloskie's statement is quite indefinite. D. T. TARAXACUM L^viGATUM (Willd.) Ok. — Macl., p. 901. Should be deleted; not known from our district. Cf. Dahlstedt, 1. c., p. ii.

Macloskie's descriptions of this species, as well as of the others, are altogether too in- complete to permit the drawing of any conclusion. I think, however, that this N. American form does not occur in the peraustral part of S. America, and, very probably, Macloskie's statement of this form's having been found in our district is based on an obscure determination. Dubious ; should in my opinion be struck out. D. T. MAGELLANICUM Comm.; Sch. Bip. var. LT>BATUM Dahlst., 1. c., p. 6. S. Patagonia, central part of Territorium of Sta.

Belgica Expedition (1897-1899) by giving an interesting summary of the number of species of the different families of Phanerogams occurring in the several islands and coasts, excluding the inner mainland of Patagonia. We copy this, adding the number included in the Falkland Is., which are not given in his lists ; nor are all the islands on the West Patagonian coast repre- sented in his Report.

Wildeman observes that no species is spread over the whole field and some of the islands contain endemic forms; but some which are now apparently localized will probably prove to be of more extensive distribution. The following are the most widespread of these species : Drymus winteri Forst, found in 14 of the 26 regions explored. Cardamine antiscorbutica Banks & Sol., found in 13 of the 26 regions explored. Nothofagus betuloides (Mirb.) Bl., found in 13 of the 26 regions explored. Perezia magellanica, found in 1 3 of the 26 regions explored. Chiliotrichum diffusum (Furst.) Dus., found in 12 of the 26 regions explored and in Falklands. Poa flabellata (Lam.) Hook., found in 12 of the 26 regions explored. Senecio acanthifolius Homb. & Jacq., found in 12 of the 26 regions explored. Accena pumila Vahl., found in 1 1 of the 26 regions explored. Apium g raveolens L., found in 1 1 of the 26 regions explored. Crassula moschata Forst., found in 1 1 of the 26 regions explored. Gunnera magellanica Lam., found in n of the 26 regions explored and in Falklands. Oreobolns obtusangulus Gaud., found in 1 1 of the 26 regions explored and in Falklands. Senecio smithii DC., found in 1 1 of the 26 regions explored. Astelia pumila R. Br.; Callixene marginata ; Colobantus subulatus ; Empetrum rubrum ; Myrteola nummularia found in 10 of the 26 regions explored and in Falklands. Berberis ilicifolia ; Cotula scariosa, found in 10 of the 26 regions explored (not in Falklands). Escallonia serrata; Lebetanthus americanus, found in 10 of the 26 regions explored (not in Falklands). Nanodea muscosa, Rostkovia grandiflora, found in 10 of the 26 regions explored (not in Falk- lands). He also remarks that all these species occur in the American continent, mostly with extensive range. One, Apiitm graveolens L., is also found in other continents. Some other species are European, but of restricted American distribution. Most of the Fuegian forms occur on the main- land ; and the islands doubtless contain many other continental forms, not yet reported from them. Thus probably the flora which now covers what are the vestiges of an ancient continent are the descendants of a vegetation of unique origin. (It is a question worthy of attention whether the similarity of the Falkland Is. vegetation with that of the continent is sufficient to justify the theory of an ancient land-connection. — G. M.) MACLOSKIE: REVISION OF FLORA PATAGONICA. 299 ANTIQUITY OF THE ANTARCTIC FLORA. A notice by E. Hackel about the Magellan Flora as related to that of Europe and North America, appears in Engler's Botan. Jahrbuch., 1907, xl (2) ; Hackel takes 83 species indigenous in Magellans-land, and iden- tically, or vicariously represented in N. America and Europe ; but wanting or extremely rare in the tropical Andes. These include 20 species of Gramineae, 12 of Cyperaceae, 36 other Monocotyledons and only 15 Di- cotyledons. Hence he concludes that Gramineae and Cyperaceae are the most ancient of the flowering plants, being probably remains of an old flora, which included such Dicots as Fagus, Veronica, Euphrasia, and which is supposed to have migrated by peculiar routes from the North Temperate to the South Temperate zone. Their absence from the trop- ical Andes centra-indicates the assumption of their overland journey by the American Cordillera. More probably there was an ancient land- connection between Magellans-land and Australia, and New Zealand, as evidenced by numerous plant species common to these lands, and also struthious birds. The supposition of their having originated in the south and thence migrating northwards is refuted by the fact that such plants as Primula farinosa L. and Gentiana prostrata Haenk., have their nearest related forms not in the far south, but in Europe and Asia.
