Bracteoles ovate, obtuse, to c. 2.0 mm long, scarious or pinkish. Flowers usually cleistogamous. Tepals ±tightly adpressed to pistils, unequal, with outer ones distinctly longer, linear-lanceolate, long acuminate, greenish becoming stramineous-brown; margins membranous, broad; outer tepals c. 5.0–6.5 (–7.5) mm long; inner tepals to c. 5.5 mm long.
