On the base of trees in woods, New Jersey to Canada and Ohio; 
common. Inner perichzetial leaves long and narrowly pointed, 
but less gradually so than in Th. scitum.  Pedicel of the same color 
as the capsule (pale yellow), and, as in all the Thuidia, obscurely 
scabrous. Peristome with the processus and ciliolz nearly or quite 
as long as the teeth. Paraphyllia multiform. Color of the plant 
green, glaucous green, or often yellowish green.

_ Prof. Macoun, of Canada, has recently sent me fine fruiting spe- 
cimens of this interesting little moss, found growing on an old stump 
near Belleville. It resembles both P7. pulchellum and Pl. latebricola, 
but is smaller than either (being the smallest of the genus). Be- 
sides it differs from the former in its inflorescence, much shorter and 
slenderer pedicel, shorter erect capsule with the outer peristomal 
: teeth much narrower and erectish when dry, and with the cilize of the 
inner peristome imperfect, perichzetial leaves less convolute and not 
plicate, stem-leaves narrower, etc. ; from the latter it differs chiefly 
in the texture of the leaves, which are also neither decurrent nor 
furnished with inflated cellues at the base.

Remarkable for the obtuse apex of the leaf, with minute decom- 
pound ciliz on the margins and coste at the base. The cost are — 
wholly distinct at the base throughout, wide apart and nearly 
parallel,
