I see no essential difference in the specimens of this plant from 
its various localities. In the Ceylon and Nilghiri plant the scales 
are larger, almost concealing the perigynium ; and in the last the 
male spike has female flowers at the base and middle. The La- 
chung specimens, from Dr. Hooker, have the perigynium occa¬ 
sionally dentate at the margins, and the orifice emarginate. Its 
immediate affinity is with O. crinita, Lam. A specimen (five 
spikes) from Ceylon, and one from Lachung (six spikes), are 
figured in Tab. CLXYIII.

The smooth flaccid culm, the soft grassy leaves, and the tor¬ 
tuous empty apex of the perigynium distinguish this species from 
its allies.
