 by basal innovations or stolons. Leaves in several ranks, the lower usually remote, 

 minute, at the flowering summit much larger and rosulate, shining, broadly obovate 

 to oblong from a narrow rarely subelasping or decurrent base, with stout costa and 

 the usually thickened bordered margin entire or mostly serrate with 1 to 3 rows of 

 firm teeth ; areolation round-hexagonal, at base hexagonal-oblong and paler. Flowers 

 dioecious or bisexual, the male discoid with very numerous axillary antheridia and 

 clavate paraphyses. Calyptra cucullate, very narrow, smooth, fugaceous. Capsules 

 inclined or pendulous on long usually strict often clustered pedicels, ovate or oblong 

 or subglobose, with short abrupt collum ; operculum convex, mamillate or more or 

 less beaked ; annulus narrow. Peristome as in Bryuvi, the inner membrane reaching 

 to the middle of the paler outer teeth ; ciliolre present in twos or threes, filiform, 

 not appendiculate.
