Plants medium to large, loosely caespitose, green to yellow-green; saxicolous. Stems 30-70 mm high, infrequently branched; in section central strand small, inner cortical cells in 2-3 rows, large, weakly thickened, outer cortical cells in 2 rows, smaller, strongly incrassate. Leaves flexuose to falcate, secund dry or wet; oval, abruptly or gradually contracted to a long, spirally twisted subula, 4.5-6.5 mm long; apex acute, toothed; margins erect to incurved, entire below, dentate in upper subula. Costa broad, filling subula; in proximal section flattened, guide cells small, 10-12, dorsal and ventral stereid bands 2-4 cells thick, surface cells not differentiated or occasionally substereids, laminal cells strongly thickened; in distal section reniform, guide cells small, 4-6, dorsal and ventral stereid bands 2-4 cells thick, surface cells occasionally substereids. Laminal cells variable in shape, elongate, sinuolate, strongly incrassate, abruptly quadrate at shoulders; short, rounded-rectangular in lower subula; basal cells long-rectangular, thin-walled towards margin. Sporophyte not known from Africa.
