Stamens 4, subequal or anterior 2 longer, inserted on apical half of corolla tube; filaments complanate, glabrous or puberulent; anthers ovoid, cells 2, divaricate, becoming confluent at apex. Style as long as to longer than stamens. Disc swollen in front. Nutlets oblong, few striate, glabrous, basal scar white, apex rounded.
