This approaches very near to the Leskea filiculeformis, the 
L.rotulata, and Leskea (Hypn., Schwaegr.) tamariscina of Hed- 
wig. From the first it differs in its much smaller size but larger 
leaves, and in its branches being never regularly twice pinnated; 
e second, in the stipules, which want the excurrent 
is the ps authority. His plant is destitute of sete, ad 1 
do not find that it differs essentially from L. roludata of Hedwig, 
which ought thus to bear the name of tamariscina. 1 shall have 
the ag sa aud of saying more of these species hereafter. 
A cinum is found as well on the continent of Africa as.
