Habitus C. penduloe, Hudson. 
The perigynium is occasionally abortive and of a lanceolate 
form. The rugose character arises from the drying of the perigy¬ 
nium, and disappears when soaked in water.

Affinis C. amplifolice, B. 
In one specimen there were a few female florets scattered about 
the middle of the male spike. It is only the lowest female spike, 
in those specimens having six or seven of them, that has a long, 
broad, vaginate bract. This is occasionally sterile, and more or 
less remote. It belongs to the TrachyclilcencB of Drejer, and in 
habit is like C. amplifolia.
