Han. In plaga occidentali Americe occidentalis. .D, Menzies, 
Caulis repens, flexuosus, inferne denudatus, superne ramosus, 
atque hic illic stolonifer, stolonibus folioso-squamosis, radican 
tibus, ramis numerosis, brevibus, erectis, simplicibus vel pin- 
natim divisis, attenuatis. Folia lutescente-viridia, nitida, 
erecta, appressa, undique imbricata, ovata, vel ovato-elliptica, 
attenuata, serrata, terminalia magis attenuata, omnia sub- 
striata, nervo supra medium evanescente instructa. Periche- 
tialia squarrosa, tenuiter acuminata, fere enervia, subinteger- 
rima. Seéa vix unciam longa, subcurvata, levis. Capsula 
ovata, cernua, fusca. Peristomium flavum, ut in Hypni genere. 
The great resemblance of this plant to HAypnum curvatum and 
H., myosuroides will strike even the most casual observer 3 while 
from the former it will be found to differ in the more acuminated 
and far more serrated leaves; from the latter in the broader and 
more elliptical ones ; and from both in the drooping capsule and 
much larger size of the whole plant. Like the species just men- 
tioned, Mr. Menzies also observes of this, that it grows suspended 
from the branches and about the roots of trees in the north-west 
eoast of America.
