Ecology & Life History
Help
Basic Description: Plants in tuft, dark green to nearly black. Stems often branched. Leaves imbricate when dry, spreading when moist, oblong-lingulate to ovate-lanceolate, obtuse to rounded at apex; margins strongly recurved to the apex or nearly so, entire or toothed at the apex; costa ending before the apex. Autoicous. Seta shorter than the immersed capsule. Capsule strongly ribbed and shrunken under the mouth when dry (Lawton 1971).
Habitat Comments: On exposed tree roots and at the bases of trees along streams. Also commonly found on large boulders at the edges of streams and rivers; occasionally on rocks which are frequently inundated. Rarely found in aquatic habitats, rather it is usually found on tree bases and rocks near streams (Vitt 1973).
