This approaches very near to the Leskea filiculeformis, the 
L.rotulatu, and Leskea (Hypn.; Schwaegr.) lamariscina of Hed- 
wig. From the first it differs inits much smaller size but larger 
leaves, and in its branches being never regularly twice pinnated 5 
~—from the second, in the stipules, which want the excurrent 
herve ;—-and from the last, in the absence of the sei@ among 
the leaves. With regard to the Hedwigian L. tamariscina, in- 
ed, it does net accord either with Swartz’s description, or 
with the specimen which he has kindly sent to me; and Swartz 
is the original authority. His plant is destitute of sete, and I 
do not find that it differs essentially from L. rotulata of Hedwig, 
which ought thus to bear the name of tamuriscina. I shall have 
the opportunity of saying more of these species hereafter. 
. laricinum is found as well on the continent of Africa as 
America
