Dioicous. Setae slender, up to 2.3 cm long; capsules nodding, oblong-pyriform, shortnecked; operculum large, hemispheric, apiculate; peristome normal; endostome consisting of a relatively high basal membrane, widely perforate segments, and well-developed, longappendiculate cilia.

    This most robust member of the subgenus in Latin America is similar to B. filiforme, but the leaves are longer (more than 1.1 mm long) and broader at the apex. Also the basal cells are wider and thinner-walled, and the setae and capsules longer.
