nata, serrata, basi in caulem decurrentia, nervo ad summum 
apicem attingente instructa, Perichetialia acuminata, in- 
tegerrima, immarginata, nervosa, fusco-viridia. Seta sesqui-

This very elegant species of Hypnum ranks naturally near 
Leskea Nove Hollandie, and Hypnum distichum of Swartz, in 
Schrad. Diar. Bot. v. iv. t. 8. Both these species, however, 
have simple stems, and their fruitstalks inserted at the very base 
of the stems. H. Lifarium has the leaves decidedly thickened at 
the margin, and the back of the nerve, upward, under a high 
magnifying power, is also slightly toothed.
