Spikelets dorsally compressed, raore or less pubescent, solitary or 
sometimes in pairs, short-pedicellate or subsessile, in two rows on 
one side of a narrow, usually hairy rachis, the pedicels often clothed 
with long, stiff hairs, the back of the fertile lemma turned from the 
rachis; lower rachilla joint thickened, forming a more or less ringlike, 
usually dark-colored callus below the second glume, the first glume 
reduced to a minute sheath about this and adnate to it; second 
glume and sterile lemma about equal, acute or acuminate; fertile 
lemma indurate, minutely papillose-rugose, mucronate or awned, 
the awn often readily deciduous, the margins slightly inrolled. 
Annuals or perennials with terminal panicles consisting of several 
or many spreading or appressed racemes, usually rather closely 
arranged along the main axis.

Cuba. The type, bearing the name in Richard’s script, was ex- 
amined in the Paris Herbarium in 1935 and proves to be the same 
as Hriochloa filifolia. Richard’s description is misleading in some 
respects, and the species was referred by Grisebach,” on the descrip- 
tion, to his Andropogon setosus, which is the basis of Sorghastrum 
setosum (Griseb.) Hitche. Grisebach, however, gives a description 
of his own and, though using the same specific epithet, does not base 
his species on that of Richard.
