Inflorescence terminal, 1-4 cm, spikelike; bracts caducous. Male flowers: sepals ovate, white ciliate; petals obovate, ca. 2 mm, white-ciliate; stamens 15-20; filaments white pubescent. Female flowers: sepals and petals as in male; ovary and styles with dense scales; styles 4-8-fid, lobes filamentous. Capsules subglobose, ca. 7 mm in diam. Seeds ellipsoidal, ca. 4 mm.
