Plants red-brown. Stems often 3-5 cm, central strand present. Stem leaves appressed when dry, spreading or weakly recurved and keeled when moist, monomorphic, elliptic-lanceolate, adaxially grooved along costa, (2-)2.5-4 mm, base scarcely differentiated in shape to elliptic, margins nearly broadly recurved in proximal 1/3-3/4 of leaf, entire, apex acute or gradually acuminate, not fragile; costa percurrent, tapering and distinctly widened at base, widened pad of cells absent, adaxial costal cells elongate, 5-7 cells wide at mid leaf, guide cells in 1 layer; basal laminal cells differentiated medially, rectangular, walls thickened and porose; distal laminal cells 13-15 µm wide, 1:1 or occasionally transversely elongated, papillae absent or simple, low, present only on the back of the leaf near the apex, lumens angular, walls irregularly thickened and trigonous with trigones about the same size as the lumens, weakly convex on both sides, 1-stratose.
