Caule brevissimo innovationibus elongato inferne nudiusculo, 
foliis imbricatis ovato-lanceolatis acuminatis laxe reticulatis

Caules fructiferi perbreves superne foliosi: innovationes copiose, 
elongate. Folia arcte imbricata, erecta, ovato-lanceolata, 
laxe reticulata, obscure serrata, acuminata, nervo attingente 
percursa. Sefa uncialis et ultra, erecta, superne valde inflexa. 
Capsula majuscula, cylindracea, cernua atque sursum Curvata, 
pallide rufo-fusca, levis. | Operculum parvum, conicum. 
Peristomium e ciliis 16, equidistantibus, remotis, gracillimis, 
albidis, obscure articulatis, basi membrana interna, ut videtur, 
connexis. 
This moss has much the habit of a Bryum, with the capsule 
resembling some Leptostoma, yet having 16, entire, equidistant 
cilie. Thus we are led to refer it to Weissia, as that Genus 
now stands, from which it will no doubt be eventually separated, 
when we come to be better acquainted with the laws which ought 
to affect the arrangement of the genera of mosses. The sack 
within the capsule, together with its stalk and apophysis are dis- 
tinctly seen, in the scarcely ripe state, through the somewhat 
pellucid outercoat.
