Dioicous ; in rather dense deep green or yellowish tufts, interwoven

 dichotomous; leaves multijugous, crowded, increasing in size upward, 

 broadly Ungulate or scalpelliform, with a short apiculus, margin minutely 

 crenulate, not bordered ; nerve vanishing below apex, vag. lam. ovato- 

 lanceolate, about half length of leaf, inf. lam. linear-lanceolate, reaching 

 base, but not decurrent; cells rather lax, rounded or oblong. Seta 

 terminal, erect, purple ; capsule erect or inclined, rather small, brown, 

 pachydermous, oval or oval-oblong; lid long as capsule, conoid, rostrate, 

 straight ; teeth cleft to middle, the legs unequal, subulate, nodulose ;

Distinguishable at once by its non-bordered leaves with large cells. 

 The var. microcarpus Schimp. appears to be only a dense form with ill- 

 developed fruit, to which Wilson's specimens from Aber closely approximate.
