Plants terrestrial or on rock, forming cushionlike or loose mats. Stems decumbent or creeping, not readily fragmenting, irregularly forked, without budlike arrested branches, tips straight; main stem upperside and underside structurally slightly different, conspicuously indeterminate, lateral branches radially symmetric, conspicuously or inconspicuously determinate, strongly ascending, 2--3-forked. Rhizophores borne on upperside of stems, throughout stem length, 0.2--0.35 mm diam. Leaves essentially monomorphic, in poorly defined pseudowhorls of 5 or 6, tightly appressed, ascending, green, linear to linear-lanceolate, (2.7--)3--5 X 0.4--0.7 mm (upperside leaves smaller than underside ones, also smaller on ascending buds); abaxial ridges present; base long-decurrent, oblique, and glabrous on underside leaves, slightly decurrent, oblique, and sometimes pubescent on upperside leaves; margins long-ciliate, cilia transparent, mostly ascending or spreading on proximal 1/2, ascending on distal 1/2, 0.07--0.17(--0.2) mm; apex slightly keeled to plane, rather obtuse, abruptly long-bristled; bristle white or transparent, puberulent, (1--)1.25--1.9 mm. Strobili solitary, (0.5--)1--3(--4) cm; sporophylls ovate-lanceolate, seldom ovate, abaxial ridges well defined, base glabrous, margins ciliate entire length or dentate near tip, apex usually long-bristled.
