avvnless glumes (valves), containing a single floret. Corolla (see 
fig. 2.) of 2 unequal, inversely egg-shaped, membranous, ribbed, 
hairy, fringed, blunt, awnless pale® (valves), which are rather 
shorter than the glumes, the larger embracing the inner one. Fila- 
ments (see figs. 1 & 3.) 3, hair-like, twice as long as the glumes. 
Anthers elliptic-oblong, cloven at each end, upright, with 2 minute 
terminal beaks (see fig. 3.) German (see figs. 2 & 4.) minute, 
roundish. Styles (see figs. 1 & 4.) 2, very short. Stigmas (see 
figs. 1,2, & 4.) rather longer than the stamens, cylindrical, downy, 
pointed. Seed loose, covered by the corolla, inversely heart-shaped, 
copiously dotted in longitudinal lines. Smith Hooker. 
The single-flowered calyx of 2 nearly equal, blunt glumes ; and 
the corolla of 2 unequal, hairy, blunt, awnless paleae ; will dis- 
tinguish this from other genera, with a panicled inflorescence, in 
the same class and order. 
Only one species known.
