Plants small and fairly slender, olivaceous to greenish yellow. Stems 0.5-1.8(-2.5) cm, ascending, subpinnately or occasionally pinnately branched to almost unbranched, usually radiculose throughout. Leaves imbricate, not or slightly altered when dry, erect-spreading to weakly recurved when moist, ovate-lanceolate, 1.5-1.8 × 0.5-0.6 mm; margins recurved throughout or often not or only weakly recurved distally the base; piliferous or rarely muticous, awn erect-flexuose, fairly long on the uppermost leaves, subulate, non-decurrent, slightly denticulate, epapillose throughout or faintly papillose in the proximal part; costa percurrent, sharply delimited from the laminal cells, superficial and not situated in a groove; 35-55 µm wide at the base; basal laminal cells rectangular, 15-45 × 4-6 µm, with moderately thickened, porose and nodulose longitudinal walls, epapillose in 2-3 cell rows at the insertion; alar cells mostly subquadrate to short-rectangular, pellucid in 3-5(-6) rows, forming a small, not or weakly convex group; supra-alar cells quadrate to subquadrate, thin-and straight-walled, forming a marginal border consisting of up to 15 cells; medial and distal laminal cells short-rectangular to subquadrate, 6-25 × 6-10 µm, opaque due to relatively dense and coarse papillae.
