Caules laxe cxspitosi, sesquiunciales,. vage bipinnatim: ramosi, 
ramulis plerumque brevibus obtusis. Folia undique imbricata, 
erecto-patentia, flavo-viridia, ovato-lanceolata, acuminata,. 
parum concava, obscure serrulata, omnino enervia, Periche- 
tialia his simillima sed angustiora, interiora magis acuminata. 
Sete numerose, breviuscule. Capsula intensé fusca, ovato- 
eylindracea, erecta vel leviter inclinata.. Operculum rostratum, 
rostro curvato, 
Thisis a small'andobscure species, having no striking character 
by which it may be readily distinguished. from its numerous con- 
geners, yet not exactly agreeing with any one hithertg published. 
It is probably a Leskea, judging at least from its erect capsule 
which is so common in that genus ;. but although my specimens 
Possess capsules with peristomes, yet this part is so minute and 
so extremely fragile that I am unable to satisfy myself as to the 
true structure of its inner teeth.
