the oblong base, and thence subulate.”—Mitten, l. c.

“This most distinct Moss has been wrongly described with dioicous inflorescence and striated leaves. In the 
specimens collected by Mr. Archer the stems are 4 inches high, but the seta is not longer than in the shorter states 
of the plant. The capsules in all the specimens are too old to afford an idea of the perfect peristome, but in every 
other particular the structure is similar to that observable in the species of Leptotrichum, and not at all different 
from that. of Weissia stricta, Hook. fil. et Wils. Fl. Antarct. Crypt. p. 98. t. 152. f. 4, which is also referable to 
the same genus." — Mitten, l. c.
