202 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



8. Paspalum densum Poir. in Lam. Encycl. 5: 32. 1804. 

 Dense bunches in ponds, Piiiar del Rio, September, Wright 3447. 



There is a second specimen of this species in the Sauvalle Herbarium, without 

 locality, erroneously numbered 3462. In the Grisebach Herbarium there are two 

 specimens of this species, one from western Cuba, 1863, numbered "866=3447," 

 the other from "Low wet savannas; Hanabana," 1865. 



9. Paspalum dissectum (L.) L. Sp. PL ed. 2. 81. 1762. 

 Panicum dissectum L. Sp. PL 57. 1753. 



Paspalum membranaceum Walt. Fl. Car. 75. 1788. 



Low grounds around ponds, procumbent. Hanabana, June 10, Wright 169 [Sec- 

 ondary number] . 



The same number occurs in the Grisebach Herbarium. A second specimen of this 

 species, from eastern Cuba, 1860, is numbered "98=3440." The specimen in the 

 National Herbarium is numbered 3440. For a discussion of the type of P. dissectum 

 L., see Contr. Nat. Herb. 12: 115. 1908'. 



10. Paspalum distichum L. Syst. Nat. ed. 10. 2 : 855. 1759.

 Playa de Marianao, Palmer & Riley 848; Herradura, Tracy 9056; Isle of Pines,

Grisebach's specimen of Wright's 1546 is from eastern Cuba; a second specimen of 

 the same species is from western Cuba, 1863, and is numbered "911=1546." In the 

 National Herbarium is a sheet of Wright's with the secondary number 292 which is 

 part this species and part P. vaginatum Sw. 



11. Paspalum elatum Rich.; Doell in Mart. Fl. Bras. 2 2 : 78. 1877. 

 Wright 3843. 



This specimen is referred to this species from description only, as no authentic 

 specimens of P. elatum have been examined. It is a much taller grass than P. plic'a- 

 tulum Michx., which it resembles, with more elliptical and less convex spikelets. 



12. Paspalum filiforme Sw. Prod. 22. 1788. 

 Paspalum swartzianwm Flugge, Mon. Pasp. 96. L810. 

 Paspalum approximatum Doell in Mart. Fl. Bras. 2 2 : 82. 1877. 



In pastures forming tufts, Retiro, July, Wright 769; Isle of Pines, Curtiss 523, 374, 

 Palmer & Riley 949; Guanabacoa, Hitchcock in 1906; Rincon, Britton & Wilson 477 

 in Herb. N. Y. Bot. Gard. 



Grisebach's specimen of Wright 769 was collected, "1860-1864," "in the edge of 

 woods, Hanabana, May 28." Another of his specimens with the secondary number 

 165, in 1865 is also from Hanabana, May 23, "in small tufts." 



Doell a refers P. filiforme Sw. to P. caespitosum Flugge. This is not the plant that 

 Swartz describes, as is shown by the original description in the Prodromus and the 

 later amplified description in his Flora. 6 Swartz describes his plant as having a 

 single spike, ovate spikelets, and filiforme leaves, while P. caespitosum has 3 to 5 

 spikes, oblong-obovate spikelets, and flat blades. 



13. Paspalum glabrum Poir. in Lam. Encycl. 5: 30. 1804. 

 Paspalum bakeri Hack. Inf. Est. Centr. Agron. Cuba 1: 410. 1906. 



Habana, Baker 1821: Triscornia, Hitchcock in 1906; without locality, Wright 298; 

 Matanzas, Rugel 869 in Herb. N. Y. Bot. Gard. 



In the Grisebach Herbarium is a specimen of P. glabrum labeled, "In small tufts, 

 sand batiks near the sea, Palma Sola, July 15," 1865, and bearing the secondary number
