Synoicous ; in dense shorter or taller tufts, green or olivaceous 

 above, brown or blackish at base ; stems with rufous tomentum, 

 fastigiate-branched. Leaves semiamplexicaul, decurrent, patulous, 

 when dry laxly imbricated and a little twisted, outer comal elliptic 

 shortly acuminate, median oblong-lanc, shortly cuspidate with the 

 reddish-brown excurrent nerve, lower ovate or elliptic, shortly pointed, 

 margin revolute with a limb of 2 — 4 rows of narrow cells, bluntly serrate 

 at apex. Caps, pendulous on a long seta, obovate- or oblong-pyriform, 

 slightly constricted below the mouth when dry, ferruginous-brown, lid 

 mammilar, large ; membrane of endostome prolonged. 



Hab. — Bogs and marshy ground. Fr. 6 — 7. 



This moss was long confounded with B. ventricosum Dicks, but differs in 

 the synoicous infl., the leaves also are more divergent and laxer, distinctly 

 cuspidate, and the capsule shorter and more regular.
