Rather small and delicate plants, sometimes aggregated in dense, palegreen
to whitish, radiculose tufts, often tinged with pink or red. Leaves
small and distant, upper not crowded, complanate, somewhat dimorphous,
especially on sterile stems, lateral leaves ovate, flatly spreading, widely
decurrent, dorsal leaves erect, smaller and narrower; margins entire or
somewhat denticulate at apex, sometimes bordered with narrower, reddish
cells; costa reddish, ceasing far below leaf apex; cells large, very lax and thinwalled,
hexagonal to elongate-rhomboidal, narrower at margins. Dioicous.
Seta red, elongate, bent above; capsule small, ovoid, pendulous; annulus
deciduous; operculum mammillate; peristome complete, teeth yellow, papillose,
segments thin, from high basal membrane, with well-developed, nodose
cilia.

Rather small to medium-sized, pale green plants becoming tinged with
red. Stems erect, about 1 to 2.5 cm. high, complanate-foliate. Lateral leaves
to 3 mm. long, broadly obovate, abruptly apiculate, entire or bluntly serrulate
near apex; costa ceasing about % leaf length; cells lax and thinwalled,
elongate-rhomboidal, 2 to 3: 1, longer and narrower at margins forming
usually distinct reddish border. Dorsal leaves much smaller, narrowly
lance-acuminate, in 2 rows. Dioicous. Seta about 6 to 8 mm. long; capsule
1 to 1.5 mm. long, pyriform, pendulous; operculum low-convex.
Common and abundant on soil and disintegrating rock on vertical banks
in wet mountainous areas at altitude of 1000 ft. and higher; Cuba, Jamaica,
Santo Domingo, and Veraguas; Venezuela.
No mature sporophytes were found in Puerto Rican collections. Sullivant
described the setae as % to 1 inch long, occasionally
