HITCHCOCK—GRASSES OF CUBA. 225 
The Grisebach specimen is from eastern Cuba, 1859, no. 1545. This species has 
been referred to P. molle Sw., but the latter is a quite different Brazilian species. It 
may be that P. muticum Forsk.¢ is an older name for this species. 
Salzmann’s specimen from Bahia, upon which Panicum equinum is based, is in the 
herbarium of Professor van Heurck at Antwerp; a duplicate isin the herbarium at 
Florence. The specimen from Reugger, Paraguay, also cited by Steudel, is in the her- 
barium of the Museum at Paris, and also belongs to this species.

The Grisebach specimens are from western Cuba, 1863, numbered, ‘‘901=3458” and 
*927=3458.”’ This is listed by Grisebach > as P. cyanescens. The type of P. parvi- 
folium is in the Lamarck Herbarium at Paris. Wright 3458 in the Gray Herbarium is 
labeled ‘‘In lagunas (ponds) Los Almacigos, July 28,’’ and ‘‘On tembladeros in 
lagunas, Asiento Viejo de San Julian, Nov.”

There is some material of this species mixed with Wright 3461 in the Krug and 
Urban Herbarium. This species occurs also in Porto Rico (Heller & Heller 982b, 639, 
Underwood & Griggs 955),and is common in the Atlantic coastal plain of the southern 
United States.

305, Taylor 36 in Gray Herbarium. 
There seems to be an error in the number of the Wright specimen. It is published 
as 3451 in Grisebach’s catalogue and in Flora Cubana, and the specimen is so num- 
bered in the Kew and the Grisebach herbaria, but in the Sauvalle and the Berlin 
herbaria the number is 3457. The Grisebach spécimen is from western Cuba, 1863, 
numbered *‘888=3451.” 
The hairs on the rachis are variable. Curtiss’s 305 in the National Herbarium is 
without hairs; the same number in the herbarium of the Cuba Experiment Station 
has hairs on some of the spikes. Wright’s 3451 in the Gray Herbarium is from ‘‘ Retiro, 
July 15, in woods (damp).’’
