CATALOGUE OF THE GRASSES OF CUBA By A. S. Hitchcock. INTRODUCTION. The following list of Cuban grasses is based primarily upon the collections at the Estaci6n Central Agron6mica de Cuba, situated at Santiago de las Vegas, a suburb of Habana. The herbarium includes the collections made by the members of the staff, particularly Mr. C. F. Baker, formerly head of the department of botany, and also the Sauvalle Herbarium deposited by the Habana Academy of Sciences, These specimens were examined by the writer during a short stay upon the island in the spring of 1906, and were later kindly loaned by the station authorities for a more critical study at Washington. The Sauvalle Herbarium contains a fairly complete set of the grasses col- lected by Charles Wright, the most important collection thus far obtained from Cuba. In addition to the collections at the Cuba Experiment Station, the National Herbarium furnished important material for study, including collections made by A. H. Curtiss, W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M. Tracy, Brother Leon (De la Salle College, Habana), and the writer. The earlier collections of Wright were sent to Grisebach for study. These were reported upon by Grisebach in his work entitled "Cata- logus Plant arum Cubensium," published in 1866, though preliminary reports appeared earlier in the two parts of Plantae Wrightianae. * During the spring of 1907 I had the opportunity of examining the grasses in the herbarium of Grisebach in Gottingen.6 In the present article I have, with few exceptions, accounted for the grasses listed by Grisebach in his catalogue of Cuban plants, and have appended a list of these with references to the pages in the body of this article upon which the species are considered. The numbers upon the labels of the Wright specimens in the Grisebach Herbarium are in many cases not the same as those under which the species were afterwards dis- tributed and under which they were listed in the catalogue. These numbers I have designated as secondary numbers. Grisebach has sometimes connected on his labels the secondary number by the sign oMero. Amer. A cad. n. ser. Vol. VIII. Part I, pp. 153 to 192, (as separate) 1860; Part II, pp. 503 to 53ft, (as separate) 1862. The grasses were included in Part II. 6Unless otherwise stated the writer has examined all the types mentioned in this paper. 183 184 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM of equality with the distribution number. The data upon the Grise- bach labels are meager, usually consisting of the number and year, together with an abbreviation for eastern or western Cuba. The distribution numbers of the grasses reported upon by Grisebach are all below 3500. Wright, after his return from Cuba, studied his col- lections at the Gray Herbarium and published his results in a series of articles in conjunction with Doctor Sauvalle, of Cuba." In the "Analce de la Academia de Ciencias, M&licas, Fisicaw y Natural es do la ITabana, Volumes V to IX, 1868 to 1872. This was reset and, an index being added, pub- lished in 1873 as Flora Cubana. The introduction to the first installment of the series (6: 196. 1868) is as follows: "Reviaio Catalog! Grisebachiani vel index planta- rum cubensium ad catalogum ("1.

Each continuation is headed "Revisto Catalog! Griaebachiani vcl Index Plantarum Cubensium; a Francisco A. Sauvalle." The reprint has a title page as follows: ''Flora Cubana.

The article was entirely reset for the reprint, but a comparison of thia portion of the original with the reprint shows very few errors. In the original the serial numbers of the Gramineae occur a* follows: Numbers. 2721 to 2727 1 157 2728 to 2755 158 2756 to 2764 200 2765 to 2769 201 2770 to 2780 202 2781 to 2791 203 2792 to 2797 204 Numbers. 2798 to 2800 2801 to 2812 2813 to 2828 2829 to 2855 2856 to 2869 2870 to 2878 2879 to 2891 1'agn. 205 206 207 208 209 287 288 In the reprint the numbers are as follows: Numbers.

The original set upon which Sauvalle's list is based is at the Gray Herbarium, and a fairly complete duplicate set is in the Sauvalle Herbarium. The sets of Wright's plants were made up at the Gray Herbarium and given herbarium distribution numbers. Each number included such collections as were thought to be of the same species. Thus it often occurs.that different specimens of the same distribution num- ber may have been collected in different localities or may even belong to different species. The data found upon the field labels in various herbaria are mentioned under each species in the present list. There is also appended a list of the species of grasses included in Sauvalle's Flora Cuban a, with references to their identification, and a list of the Wright numbers in sequence with their identification. The plan followed in the present paper is to give under specimens cited a list of the specimens found in the herbarium of the Estacion Central Agronomica, including the Sauvalle Herbarium, and in the National Herbarium, without statement as to the herbarium in which they are deposited. To these are added specimens found in the Gray Herbarium which do not occur in the herbaria just mentioned, and finally, specimens in the Herbarium of the New York Botanical Garden (Herb. N. Y. Bot. Gard.), including the herbarium of Colum- bia University, of which the Torrey Herbarium forms a part, which are not found in the others mentioned. The specimens collected by the staff of the botanical department of the Cuba Experiment Station are numbered in a single series and are indicated in this list by the letters IIC (Herbarium Cubae). The data for the Wright specimens, given in the paragraph devoted to the enumeration of specimens, are understood to be found with the specimens in the Sauvalle Her- barium. Additional data, found with specimens in other herbaria, are quoted in the succeeding paragraph devoted to notes. Grisebach enumerated 154 species of grasses in his catalogue. Sauvalle's Flora Cub ana includes 170 species. The present list includes *22S species or well-marked subspecies. KEY TO THE GENERA."

It differs from E. punctata in the narrower blades and (he shorter awn to the fruit. Allied to these is the Porto Rican Eriochloa subglabra (Nash). [Momwhne subglabra Nash, Bull. Torr. Club 30: 374. 100:5; Erioddou punctata subglabra Urban, Symb. Antill. 4: 85. 1903). This species differs from E. mmosa in the broader blades and pronouncedly velvety nodes, and iti habit; from E. punctata in the mucronate, instead of slender-awned, fertile lemma, and from both in having a etaminate (lower in the axil of the sterile lemma. Urban reduced this to a variety of E. punctata without having seen the plant. 23. ISACHNE R. lir. Prod. 196. JS10. 1. Isachne leersioides Griseb. Mem. Amer. A cad. n. ser. 8: 533. I8l>2.

The specimen of Wright's 1544 in the National Herbarium labeled, "Sandy pine woods, Pinar del Rio, Sept.," is partly this and partly S. lewcocoma Nash. Ilackela bases his P. curvinerve upon this portion of Wright 15-14. The characters which he mentions, such as the smooth glumes with incurving nerves, are found not infrequently among specimens of S. filiformis from the northern United States, whence the type was collected byKalm. In the specimen of 1544 in the National Herbarium (the smaller portion with spikelets only 1.5 mm. long) part of the panicles have nearly glabrous spikelets, and part have long-pubescent spikelets. This differs distinctly from the other part of Wright 1514, which Ilackel may have taken for the true S. filiformis. The amount of pubescence upon the s pikelet is quite variable in this species as in others of this genus. The si/.e of the spikelets, however, is fairly constant. In the Grisebach Herbarium there are two specimens of this from eastern Cuba, one collected in 1859 numbered 1544, the other in 1860 numbered " 107=1544." 3. Syntherisma leucocoma Nash, Bull. Torr.

Mayari, July 24.*' This species is distinguished from P. nm rant hum by the pubescent culms, bearded nodes, spreading vernal panicles, and short, flat autumnal blades on zigzag stems. The spikelets are 2 mm. long. It occurs in Florida and in Porto Rico (Heller 982). 7. Panicum caerulescens Hack, in herb. Vernal form cespitose, of a somewhat glaucous bluish green color; culms erect or as- cending, 40 to 75 cm. high, glabrous; sheaths usually less than half as long as the inter- nodes, glabrous or the basal ones sparingly pubescent; blades ascending or spread- ing, commonly purplish beneath, glabrous or rarely a few hairs around the base, 5 to 8 cm, long, I to 7 mm. wide, the margins? nearly parallel for two-thirds their length; panicles usually short-exserted, 3 to 7 mm. long, one-half as wide or less, the branches narrowly ascending; spikelets 1.5 to 1.0 mm. long, 0.9 mm. wide, obovoid, blunt, very turgid, glabrous, first glume about one-lhird the length of the spikelet; second glume and sterile lemma subequal, the glume scarcely as long as the fruit at maturity; fruit 1,4 mm. long, 0.8 mm wide, ellipsoid. Autumnal form erect or leaning, sometimes decumbent at base, prod ucing short, densely fascicled branches at the middle and upper nodes, these tufts scarcely as long as the primary internodes, the reduced blades ascending, more or less involute; the reduced panicles with only a lew long-podiceled spikelets. Closely related to P. roanokeme. a species of the southern Atlantic coastal plain of the United States, from which it is distinguished by the narrow panicles and smaller spikelets and by the t ufted branches of (he autumnal form. The type is IHUkmck, 700, '"In glade among Spartina, etc., stretching up through the tall grass, Miami, Florida, April 3, 1900:" TV S. National Herbarium no. 558380.

In the National Herbarium are two Wright specimens of this, numbered 740 and 741. The latter number is probably an error, the label having been interchanged with that of a specimen of L. fascicularis. I n the Gray Herbarium there are two sheets numbered 741, of which one is L. filiformis from "Cultivated ground, Valestina, Nov. 12," 1865, the other L. virgata. The type of Festuai filiformis Lam." "ex Amor, merid. Comm. IX Richard " upon which Leptochloa JiUformis Beau v. is presumably based, has not been examined, and the description is insufficient for identification. This name may be found to apply to this species. 3. Leptochloa spicata (Xccs) Scribn. Proc. At ad. Phila. 1891: 304. 1891. Bromus spicatus Nees, Agrost. Bras. 47L 1829. Triscuspis simplex. Grist'b.
