Pistillate flowers with stout pedicel, becoming 1.5 cm long; calyx-lobes ovate-oblong, ca as long as in 3'; petals suborbicular, shortly unguiculate, finely denticulate, 1.5-1.7 mm long, 2-2.3 mm broad; ovary abruptly or gradually passing into the thick stylar column, the stigmas dilated, reflexed, crenulate at the ends.
