besides the above characters, the stems are more compactly czspitose ; the a

and consistence of the two is uniform ; the cellular tissue of the leaves not so 
lax ; and the habitat is on animal substances, or on the dung of carnivorous ani- 
mals. — (Name from tetpam)0os, fourfold, and ddev, tooth ; the teeth of the peri-
