436 TRANS. OF THE ACAD. OF SCIENCE. 
Scales similar to those of the staminate flowers. 
Three minute rudimentary stamens at the base of the short- 
stipitate, compressed, lenticular ovary, which at the aper 
bears 2 rather short erect styles and elongated aloes 
truding from the apex of the fio abies air of the stigma 
simple, rather short and scarcely dentat 
Mature head ventricose, thick, pM hard, enclosing 
the loose grain. Grain about 1 line oe , orbicular, ovate, flat 
on the outer (turned towards the of 
the pe d) and convex on the inner face, 2-pointed at the 
apex by the persistent bases of the styles. oe on the 
flat ae side of the grain and almost as long as 
Each spike or head has, with very rare ete at the 
upper end an incomplete madi culasy spikelet, consisting of 
a single -pointed up lume. This, with the similar 
looking lower pee of the lowest spikelet, seems at first 
glance to form an involucrum for the head; or the 1 
giomnce together have been taken for an invorumeens the 
er glumes were overlooked, and the plant placed with the pan 
ceous genus Anthephora, Schreb., which is closely ail to 
Cenchrus. From the analysis given above, it will be 
our plant ; and that the structure of the head is ent 
analagous to that of the staminate oe of this and ne 
of the a cams grasses in general, fr which the 
lo-grass can in no manner be separated.
