Hab. Trunks and branches of trees in dry places : the variety 

 on the base of trees, stones, &c, near the ground, affecting 

 damp situations, Southern States. — Common. 



The size of this species, and the form of its leaf, capsule, oper- 

 culum, etc., are subject to variations, depending mainly on its 

 location. 



The var. rupestris appears to resemble very closely (if, indeed, 

 it is not the same as) Anisodon tenuirostris, Bryol. Europ., 

 found only in the Southern States, and of which we have seen 

 no authentic specimens.
