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 specie's in those countries, half of them new to science ; and now the Magellan mosses number 444 species ; MACLOSKIE : 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.

E. Patagonia, by Puerto Mazaredo on bushy steppe. This species belongs probably to the section Dioicopoa. The description of Poa pubiflora Benth. shows that a very close relation exists between that species and the present. P. pubiflora is denoted by "palea inferior undique molliter pubescens et carina longiuscule ciliata," while in P. Dusenii the floral glume is hairy only in its lower part and its carina scarcely ciliate. Bentham's brief diagnosis gives no statement about the ligule which, therefore, must be presumed not to show any conspicuous 56 PATAGONIAN EXPEDITIONS I BOTANY. character. The ligule of P. Dusenii, on the other hand, is long and includes in the innovations the following leaf resembling a tube. POA FLABELLATA Hook. fil. Syn. P. ccespitosa Forst. The tussock grass is found also in South Georgia, in the Falkland Is., and in the smaller islands, is almost dominant, often surrounded by Chiliotrichium diffusum, and with Poa annua L. and Apium graveolens L. growing near it.

Hordeiim secalinum Schreb. was published 1771 and Hordeum pratense Huds. 1778 in the second edition of Hudson, Flora Anglica (not in the ist 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. (Mac!., 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 I 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, Kiikenthal (in Pflanzreich IV, 20, 1909), compares them with the World of Grasses, by 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 Caricoideas, 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 monoscious 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. 1 1 . 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. Kukenthal 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 Psetido- carex. The other sections (together making Eu-Uncinia] art Platyandrce, 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.

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.

It certainly does not belong to the flora of S. Argentina, and still less to that of Patagonia.

We observe that Skottsberg in his description of the Vegetation of the Falkland Islands "a Botanical Survey of the Falkland Is.," p. 19, expresses the opinion, that the specimen now being considered, which was found by him in the Falklands, is not an independent species, but only a reduced form of y. 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. American, extends south into Argentina, and it would therefore not be surprising if it should be met with also in the neighboring parts of Pata- gonia. 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 I 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.

D. 90 PATAGONIAN EXPEDITIONS: BOTANY. * LUZULA PUMILA Hook. — Macl., p. 302. (Sub. Juncoides piimilum. ) According to Spegazzini, this species occurs in S. Fuegia, but, according to Buchenau, it is confined to New Zealand ; I have not seen a Fuegian specimen. D. L. RACEMOSA Desv. — Macl., p. 302. (Sub. Juncoides racemosum.] Is to be deleted. 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.

Spegazzini describes the plant as having a bulb ; this description is not quite correct. The subterraneous stem consists of a well-developed rhizome ending with an oval bulb. The roots emanate not from the bulb, as stated by Spegazzini, but from the rhizome. CALLIXENE Juss.— Macl., p. 307. The name Callixene of this genus should be replaced by Luzuriaga Ruiz et Pav. Cf.

A. PYGMvEA Herb. — Macl., p. 312. (Sub A. pygmcza Willd.) Should probably be deleted. This species belongs to the flora of Peru and does not occur in Patagonia, or its occurrence here is, at least, very doubtful. According to Holmberg (Holmberg, Amarill. Argent.) this species is not observed in Patagonia. My earlier statement of its occur- rence in Fuegia is incorrect. D. Professor Skottsberg writes : "I have compared true Alstrcemeria pygmcea from Bolivia and Peru with this plant from Patagonia, called by Philippi A '. patagonica ; they are different species."

Thun- berg was the first to describe the plant, viz., under the name of gladiolus biflorus. According to the international rules of botanical nomenclature the name of this species should be S. biflorus. S. ODORATISSIMUS (Lindl.) Miers and S. patagonicus Speg. — Macl., p. 319.

Arachnites Pfitz. has the limb of leaf suddenly contracted to a petiole ; sepals long, tailed. Pfitzer & Kraenzlin make it a section of Dendro- chilmn; several species in the Orient; but no A. uniflora is named, and no Dendrochilum uniflorum in their Orchidaceae. Fam. 21. ORCHIDACEAE. — Macl., p. 320. In Engler und Prantl, Die natiirlichen Pflanzenfamilien, the genus Asarca is not separated from the genus Chlorcza, 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 Chloraa. 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. Spike mostly few-flowered, bracts lanceolate, surpassing the ovary. Dorsal sepal broadly ligulate, acute, scarcely concave ; laterals broadly ovate, contracted to a tail ; petals obovate, oblong. Nerves papillate near the base. Labellum shortly clawed with 2 basal calli ; the lateral lobes diverging and reflexed, oblong rounded. Gynostemium very short. Flowers white, angled with the ovary with green lines, and green tails of the lateral sepals. S. Patagonia, Lago Argentine ; also in Chili. A. ARANEANA Phil. S. section of Central Chili; S.

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 Argentino — 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. POLYGONACE.E. — Macl., p. 348. RUMEX L. R.

Kuntze, the inner perianth-leaves of ft. crispissimus 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. 129 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 molaceus, 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 Nasturtiohtm 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 I BOTANY. zini, as a southern South American genus, and is described in Macl., p. 427. Its silicle 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.)

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.

(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.

The corrections are here so numerous that it seems to me necessary to give a quite new explanation of the species. Before doing so, I remark that the following are to be deleted : The plants referred to : C. amara L., C. antiscorbutica Banks & Sol., C. hirsuta L. and its var. magellanica (Phil.), C. strictula Steud., and per- haps C. ciliata Phil., all belong to Cardamine glacialis (Forst.) Hook. f. C. corymbosa Hook, f., not in this region. C. pygmcea Dus. belongs really to genus Nasturtium (Roripa); but spe- cifically is scarcely determinable. C. rostrata Gris. var. dichondroides Speg. is identical with C. integri- folia Phil. The following species should also probably be deleted : C. ciliata Phil. — not mentioned in Gilg & Muschler's Synopsis of S. American Crucifercz; perhaps identical with C. glacialis. 136 PATAGONIAN EXPEDITIONS I BOTANY. C. ramosissima Steud., identical with C. flaccida Cham. & Schlecht., which occurs in Chili, perhaps also in Patagon., according to Spegazzini ; not mentioned in Schulz's monograph of Cardamine. P. 435 : C. callitrichoides Speg. is to be transferred to C. valdiviana Phil, as a variety; and C. nana Barn, to C. chilensis DC. as a variety. And some new species are to be added. Dr. Dusen has furnished the following new enumeration of the Patagonian and Fuegian species of this genus, based on O. E. Schulz, Monographic der Gattung Cardamine, in Engler's Bot. Jahrb., 32 (1907), and on Gilg & Muschler, Aufzahlung aller zur Zeit bekannten sudamerikanischen Cruciferen, in Engler's Bot. Jahrb., 42 (1909), referring chiefly to the former of these papers. i.

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 caespitose 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 Brayofisis, 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. ANDINA Phil. — Macl., p. 478.

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.

This appears to us to be the rightful name of this genus of Geraniacece; not being invalidated by the very closely similar name (Wendid] of a section of a genus of a different family, nor by subsequently elevating that section to be an independent genus. The difference of spelling (as well as of pronunciation) precludes confusion ; and the generic name is not preoccupied by serving in a lower capacity, even if the name were identical. P. 536: W.

Should be deleted. The plant described in Gay, Flor. Chil., I, p. 452, by Barneoud under the name of O. articulata — not by Gay, as Macloskie says — is a Chilian and not a Patagonian one, as Macloskie seems to believe, and no notice should therefore be taken of that plant. The plant Macloskie has in view was collected near Rio Negro by Lorentz and Niederlein, members of the Rio Negro Expedition under command of General Roca. In the botanical part of the reports of that expedition, p. 201, it is stated that the plant now in question very well agrees with the description of O. articidata Sav., or to cite the authors: "corresponde bastante bien con la diagnosis de la O. articttlata Sav."

Since the description of A. trifoliata Dus. was published, I have had opportunity to compare the type specimen with specimens of A. ranun- culus.

The variety with trifid leaves and spini- form, rather long lobes is the commonest one in all Patagonia. M. ULICINUM Gill, et Hook. Should be struck out ; Macloskie's statement of this species occurring in Patagonia is based on an erroneous determination. Dr. K. Domin, preparing a monograph of the genera Azorella and Mulinum, has kindly informed me that M. spinosum Pers. is only a variety of M. ulicinum. This variety is, as far as I am aware, not yet described. The plant reminds us, as to its aspect, of Mulinum cuneatum Hook, et Arn. It is, perhaps, not impossible that Spegazzini's statement of M. ulicinum having been found in S. Patagonia, at Rio Sta. Cruz, concerns this variety, Mulinum spinosum of Pers. The variety was collected by Hatcher at Rio Chico, by Dusen at Rio Sta. Cruz. D. P. 633 : M. CUNEATUM Hook, et Arn. According to Spegazzini, Plant. Pat. austr., p. 524, this species occurs in S.

In the reports of the Rio Negro Expe- dition the authors of the botanical parts, Lorentz and Niederlein, mention MACLOSKIE: REVISION OF FLORA PATAGONICA. 193 a tall Eryngium growing in the pampa and take it, with some hesitation, to be E. agavifolium Gris. They compare the plant also with E. san- guisorba Cham, et Schlecht. It is very probable that the plant in question actually belongs to E. agavifolium Gris. Neither Hieronymus nor Spegazzini mentions this species as occurring in the Rio Negro dis- trict or in other parts of Patagonia ; but a plant man-high, as it is, can scarcely be overlooked, and it is therefore very improbable that this species occurs in Patagonia.

It may be questioned, I think, whether the latter species is not synony- mous with the former one. During my travels in Fuegia and S. Pata- gonia I very often met with numerous specimens of a Gentiana, all referring to G. magellanica Gaud., or in so few cases to a variety of that species. In my representation of the vegetation of Fuegia and Magellan — die Gefasspflanzen der Magellanslander, p. 137 — I have incorrectly stated that G. patagonica Gris., instead of G. magellanica Gaud., occurs in the peraustral parts of S. America. G. patagonica Gris. is unknown to me and seems to be a very doubtful species, probably identical with Gaudichaud's species, this being already accentuated in other works. D. P. 662 : G.

The plant now in question was found by me at Puerto Madryn, on the east coast of Patagonia, and has been noted in my representation : "Beitrage zur Flora der Ostkliste von Patagonien — Wissenschaftliche Ergebnisse der schwedischen Exp. nach den Magellanslandern, Bd. Ill, no. 5, p. 255. It was not stated there that the plant coincides with Frankenia cymbifolia Hook., but only that it resembles and may be compared with that species. But the plant turns out to be a true Frank- enia and agrees with Frankenia patagonica Speg. (described in Macl., p. 579)- D. EVOLVULUS L. P. 667 : E. INCANUS Pers.

POLEMONIACE^E. — Macl., p. 667. Our views as to the genera and species of this family have been some- what revolutionized by the researches of A. Brand, published in Engler's Pflanzenreich, IV, 250 (1907). 1. He fixes the limits of the genera by help of the fact that Gilia and Phlox have the mature calyx at length ruptured by the growth of the fruit, and their leaves may be alternate or opposite; whilst the species which are not thus ruptured, and whose leaves are always opposite are made to form the genus Navarretia. Collomia, in distinction from all these, has folds in the sinuses of the calyx, and no rupturing with the enlarging of the fruit ; and Gymnosteris is set apart by its leafless stem. He also cuts up the genus Gilia into subgenera and sections, and estab- lishes some subspecies as well as varieties under them. 2. The following is an exhibit of his system, as applied to the Pata- gonian forms. A i. (Non-Patagonian trees or shrubs, as Cob
