fertifloris latioribus, etc. 
The slight membranous texture of the perigynium and the ven- 
tricose form of the species of this group, scarcely admit, through 
the pressure of drying them, of a satisfactory idea of its form. I 
have seen but few specimens from Japan, and not all of them fully 
mature.

The occasionally lax inflorescence at the base of the spike, the 
three stigmas, and triquetrous achenium separate this species 
from C.fcetida and its allies, and perhaps ally it with O. mucronata 
to the Ferruginece. Kunth alone notices the racheola, which I 
have observed in every perigynium I have examined.
