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, /Iitehcock 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 Dayaniguas Sept.’’ and ‘‘Pinales, 
Dayaniguas Sept.’’ Anothersheet has a blank label, ‘3480 Anatherum inerme Gris.’ 
In the Grisebach Herbarium are two sheets of this, one marked 3481 on an 1860-64 
label, and another marked ‘8993481, Cub. occ. 1863." Thespecimenin the National 
Herbarium with the number 3481 has this on an 1865 label. 
In the Grisebach Herbarium there are two other sheets of this species, marked 
Anatherum inerme Griseb., ‘3480 Cuba 1860-64,” and ‘‘898=3480, Cub. oce. 1863.’’ I 
have not seen the type of Anatherwm inerme (Steud.) Griseb.« (Andropogon inermis 
Steud.)°, which is from Venezuela, but Hackel placesit under Andropogon spathiflorus 
as variety inermis.¢ LI do not 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 
“34805481” and is from ‘‘pinales (wet), Los Almacigos, July 29;”’ another from the 
same locality is marked ‘‘3481=3480.”’

Grisebach’sspecimen is labeled ‘*Cub. occ. 1863”? and is numbered ‘‘914=3482.”? The 
Wright specimen in the National Herbarium has an 1865 label. Wright’s 3482 in the 
Gray Herbarium is from “‘savannas, Almacigos, July 25.’’ One sheet of Wright’s 1558 
in the Gray Herbarium is this species, the other is A. brevifolius.
