Stems scattered through tufts of other Jungermannie, very 
short, upright or slightly recurved, pale dusky olive. Leaves 
at the base, and again at the summit of the shoots, the 
smallest ; hence the entire stem and leaves appear somewhat 
elliptical. The leaves are very concave, the one immediately 
above is partly received into the one next below ; they have 
an uneven margin, which, however, is quite entire except on 
the terminating pair on whicha solitary tooth may sometimes 
be descried on the upper margin. 
From the North American Plagiochila porelloides, Lind., 
our’s may be distinguished by its simple stem, by the thick- 
ness of the short shoot in proportion to its length, and by the 
anterior margin being incurved.
