With all the habit of a Neckera this plant is possessed of a pe- 
ristome, which, according to the characters laid down by Hed- 
wig, should constitute it a Leskea. 1 cannot, however, resolve 
on separating it from a genus in which N, planifolia, which it so 
very strongly resembles, is placed ; of which latter species it may 
also be observed, that it possesses, in common with the subject 
of the present plate, the membrane uniting together all the inte- 
rior teeth of the peristome. This is a very stately plant, having 
upright stems, bare of branches at the base, and thickly clothed 
above with bipinnated ones, which, as well as the leaves, are al 
regularly bifarious. Those of the main stems are strikingly like 
the leaves of N. pennata, while those growing on the branches are 
nearly orbicular.
