This was distributed in the exsiccatae of North American Plants as 
Eragrostis lugens Nees. 
Other specimens in the U. S. National Herbarium, all from dry 
sandy pine woods in western peninsular Florida, are: Tampa, Curtiss 
C in 1886, Combs 1342; Lakeland, Hitchcock 841. What appears 
to be the same species comes from the vicinity of Mt. Orizaba, Mexico, 
Bourgeau 2643. Another specimen of the same collected in Mexico by 
Botteri, but without definite locality, may come from the same region. 
This species resembles E. lugens Nees, which differs in having 
smooth foliage, longer spikelets and longer and more acute lemmas. 
Eragrostis flaccida Lindm., from southern Brazil, is more delicate, 
with smaller and more slender spikelets.

scabrous beneath, 12 to 20 cm. long, 5 to 10 mm. wide, the auricles 
minute; spikes long-exserted, slender, erect, 10 to 15 cm. long, the 
rachis hispid-scabrous on the margins, the spikelets somewhat distant, 
exposing the rachis, not reaching the one above on the same side; 
spikelets appressed, 10 to 20 mm. long, green or sometimes purplish, 
3- to 6-fiowered; glumes 5 to 10 mm. long, about half as long as the 
spikelet, broad, abruptly acute, glabrous or sometimes villous near 
the base, distinctly 3-nerved, with sometimes i or 2 pairs of secondary 
nerves, the margin scarious, the nerves more or less scabrous; lemmas 
10 to 12 mm. long, obscurely nerved below, distinctly 5-nerved above,
