sime binervia. Perichetialia lanceolato-acuminata, enervia,

Not being so fortunate as to possess the calyptra of this hand- 
some moss, I dare not venture to follow Sir J. E. Smith in making 
it a Hookeria, with which genus it does not tome appear to have 
much natural affinity. It has a tree-like mode of growth, very 
similar to Neckera dendroides, N. planifolia, Leskea concinna, 
Hypnum neckerioides, &c. differing, however, from all these in 
the foliage and fructification. In its leaves and capsulas it bor- 
ders upon H. flewile. (Tan. CX.)
