HYPNUM MNIOIDES, 
Hypnum caule erecto ramoso, foliis undique imbricatis 
erecto-patentibus flexuosis siccitate tortuosis lineari- 
lanceolatis, marginibus serratis, neryo attingente, cap- 
sula suberecta ovato-cylindracea. (Tas. LX XVII.) - 
Has. Staten Land prope Cape Horn. D. Menzies, 1787. 
Caules hi-tripollicares, erecti, flexuosi, basi ferrugineo-tomentosi, 
superne ramosi, ramis subfastigiatis paululum curvatis. Folia 
undique imbricata, lurido-viridia, erecto-patentia, flexuosa, 
lineari-lanceolata, paululum carinata, marginata, serrata, sic- 
citate crispata, nervo dorso serrato, valido, ad apicem attin- 
gente percursa, Perichetialia nervosa, ovata, longe acumi- 
nata, acumine flexuoso, serrato. Seta sub-bipollicaris, erecta, 
flexuosa, rubra, prope basin ramorum inserta, Capsula erecto- 
curvula, ovato-cylindracea, fusca. Calyptra et operculum de- 
sunt. Peristomium ut in Hypno, 
Two other individuals of the genus Hypnum (H. Lasilare and 
spiniforme) have the same remarkable upright and Bryum-like 
mode of growth as the present species, which differs from the 
former in its having leaves which are narrower and marginated, 
and not at all bifarious, and in its nearly erect capsules, and which 
may be immediately distinguished from the latter by its almost 
erect, less rigid and broader leaves, and by the insertion of the 
fruitstalk, which, while it is in the present plant at the origin of 
the branches, is in H. spiniforme at the very base of the plant, 
among the roots, Authors have described H. spiniforme as 
having distichous leaves, which is not the casein my specimens; 
so that it and H. mnivides will rank in the same division of the 
genus, and ought to be placed close to each other.
