Stem and branch leaves slightly differentiated. Stem leaves erect, often slightly incurved, sometimes subsecund at the tips, erect-spreading when dry, ovate or ovate-lanceolate, acute to acuminate, not or slightly biphcate at base; margins narrowly recurved in the lower half or more, entire or occasionally serrulate near the apex; costa variable, often ± forked and ending at or below midleaf or very short to nearly lacking, sometimes double (and extending as much as 2/3 up the leaf); cells small, thick-walled, smooth or obscurely bulging-papillose at back, rounded or slightly elongate and oval, those at the basal margins subquadrate in several rows. Dioicous. Perichaetial leaves erect, narrowly acuminate from a ± sheathing base. Setae smooth; capsules inclined and asymmetric, oblong-cylindric, contracted below the mouth when dry, red-brown; annulus narrow; operculum obliquely rostrate from a convex-conic base; exostome teeth yellowish; cilia of endostome paired or sometimes rudimentary.
