In this species the margins of the leaves are strikingly re- 
curved, but not revolute as in T, pilifera (Musc. Exot, Tas. 
XII.) and in the European T.revoluta, nor are the stems elongated 
and branched. Some of the specimens of Barbula obtusifolia 
(Schwaegr.) are indeed described as having the stems nearly 
as short as in the present plant, and the leaves bearing the ap- 
pearance of being recurved at the margins ; but Schwaegrichen 
assures us that the margins are in reality thickened ; moreover, 
the apices are in that species very obtuse, the fruitstalk is short, 
and the operculum long and subulate.
