Plants terrestrial, forming loose to compact mats. Stems creeping, not readily fragmenting, upperside and underside structurally slightly different, irregularly forked, without budlike arrested branches, tips straight; main stem indeterminate, lateral branches determinate, ascending, 1--2-forked. Rhizophores borne on upperside of stems, throughout stem length, (0.17--)0.2--0.3 mm diam. Leaves monomorphic, not in defined pseudowhorls, loosely appressed, ascending, green, linear-lanceolate, (1--)2.5--3 X (0.25--)0.4--0.6 mm (leaves in secondary and tertiary branches smaller); abaxial ridges inconspicuous; base rounded and adnate or cuneate and slightly decurrent, glabrous, seldom pubescent; margins short-ciliate, cilia transparent, scattered, ascending, 0.02--0.75 mm; apex plane, blunt, acute to slightly acuminate (not distinctly bristled). Strobili solitary, 2--4 mm; sporophylls deltate-ovate to lanceolate-ovate, abaxial ridges not prominent, base glabrous, margins short-ciliate, apex not keeled, acute.
