Flowers 1-3 together at the ends of short axillary branchlets bearing much reduced leaves. Peduncles 5-8 mm long, subtended by lanceolate bracteoles. Sepals 3 mm. long, widely ovate, acute, obtusely convex behind the apex. Petals 1-1.5 cm long, ovate-lanceolate, tipped with a small gland, with a subquadrate basal claw, slightly concave above, with several conspicuous glands about the middle. Stamens with stout filaments. Staminodes 4 mm long, linear-lanceolate, tipped with a large conical gland, fleshy, slightly concave above. Disk fleshy, crenulate.
