 The following are in the herbarium of the New York Botanical Garden: Santiago de 

 Cuba, Taylor 91; Isle of Pines, Curtiss in 1904; Madruga, Britton & Shafer 721; 

 Eggers 5361. 



The three Wright specimens in the Grisebach Herbarium are: Eastern Cuba, 1860, 

 no. "119=3426;" no. 299 of 1865; and eastern Cuba, 1859, no. 1^37. In Sauvalle's 

 Flora Cubana the number appears as 3829 instead of 2829. The specimen in the Gray 

 Herbarium is numbered 3829. 



4. Sporobolus purpurascens (Sw.) Hamilt. Prod. Fl. Ind. Occ. 5. 1825. 

 Agrostis purpurascens Sw. Prod. 25. 1788. 



Vilfa'grisebachiana Fourn. Mex. PI. 2: 98. 1886. 



Sandy pine woods in large tufts, Pinar del Rio, October, Wright 3427a. 



The two Wright specimens in the Grisebach Herbarium are: no. ''907=3427 " from 

 western Cuba, 1863, and "no. "885=3427", 1863. The type of Swartz's species is 

 'at Stockholm; the spikelets are 2.5 mm. long, Fournier noticed thedifference between 

 the two species (S. cubensis and S. purpurascens) distributed by Wright under 3427, 

 but described as new the one already named. Wright 3427a in the Gray Herbarium 

 is from "savannas, Chirigote, July 11." 



5. Sporpbolus virginicus (L.) Kunth, Rev. Gram. 1: 67. 1829. 

 Agrostis virginica L. Sp. PI. 63. 1753. 



Wright 291; Wright 2830 in National Herbarium; Habana, . jBa^er HC 1810, Leon 

 284; Mariel, PaZmgr cfc Riley 736; Isle of Pines, PaZmer d: Riley 955, 1122; Matanzas, 

 Britton & Wilson 151 in Herb. N. Y. Bot. Gard. 



The Grisebach specimen is no. 291 in 1865, "Seashore, Matanzas, July 8." .In 

 Sauvalle's Flora Cubana this is numbered 3830, which is probably correct, as the 

 specimen in the Gray Herbarium is also numbered 3830. 



64. CAPRIOLA Adans. Fam. PI. 2: 31, 532. 1763.« 



4. Capriola dactylon (L.) Kuntze, Rev. Gen. PL 2: 764. 1871. 



Panicum dactylon L. Sp. PL 58. 1753. 



Cynodon dactylon Pers. Syn. 1: 85. 1805. 



Wright 3814; Santiago de las Vegas, Baker HC 386, Hitchcock in 1906; Habana, 

 Leon 290; Cienfuegos, Combs 540 in Gray Herbarium. 



66. CHLORIS Sw. Prod. 25. 1788. 



Spikelets awnless; spikes dark brown 6. C. petraea. 



Spikelets awned; spikes green or yellow. 



Spikelets distant, diverging; spikes delicate, scarcely 1-sided. 2. C. cruciata. 



Spikelets contiguous; spikes not delicate, conspicuously 

 1-sided. 



« There is some question as to the standing of Capriola as a genus, since it is based 

 upon "Gramen dactylon ofiic." (Adans. Fam. 2:31 and 532. 1763.) But since 

 Linnaeus cites under Panicum dactylon "Gramen dactylon, radice repente, S. offi- 

 cinarum Scheuch. Gram. 104" we may assume that Adanson wished to base his 

 genus on this species, though he does not quote a definite author.
