Type, Cuba, Wright 3899, no. 35320 in U. S. National Herbarium. 



Sandy pine woods, western Cuba. In addition to the type this species is represented 

 by: Herradura, Hitchcock in 1906, Tracy 9069. 



The specimen of Wright 3899 in the Sauvalle Herbarium is labeled "Sandy pine 

 woods, Pinar del Rio. Sept. Culms few or single, scattering." 



This species is named for Mr. George V. Nash, who, while studying the species of 

 Andropogon in the National Herbarium, suggested that the above-mentioned speci- 

 mens did not belong to A. leucostachys, to which they had been referred. The species 

 is allied to A. leucostachys H. B. K. and A. subtenuis Nash.

The Sauvalle specimen has two labels, "Savannas 1 >ayaniguas Sept." and "Pinales, 

 Dayaniguas Sept." Another Bheet has a blank label, "3480 Anatherum inerme Gris." 

 In the Grisebach Herbarium are two Bheets of this, one marked 3481 on an 1860-64 

 label, and another marked "899=3481, Cub. occ. 1863." ThespecimenintheNational 

 Herbarium with the number 3481 has this on an 1865 label. 



In the Grisebach Herbarium there are two other sheets of this species, marked 

 Inatherum inerme Griseb., "3480 Cuba 1860-64," and "898=3480, Cub. occ. 1863." I 

 have n"i seen the type of Anatherum inerme (Steud.) Griseb.a (Andropogon inermis 

 Steud.)&, which is in mi Venezuela, but Hackel placesit under A ndropogon spathiflorus 

 as variel y inermis. <= [do qo1 see that Wright's 3480 differs from 3481 . Nees's type at 

 Munich is' the same. One sheet of this species in the Gray Herbarium is marked 

 ;; Iso 3 is! " and is from "pinales (wet), Los Almacigos, July 29;" another from the 

 same locality is marked "3481=3480."

 Gray Herbarium is from "savannas, Almacigos, July 25." One sheetof Wright's 1558 

 in the Graj Herbarium is this species, the other is I . brevifolius.
