Petals 5, erect to suberect, usually smaller than sepals, base usually prolonged into a spur. Stamens numerous; filaments linear-filiform, 1-veined. Staminodes ca. 7, membranous. Pistils (4)or 5(--10); style ca. 1/2 as long as ovary; ovules numerous. Follicles narrowly cylindric, prominently veined; styles persistent. Seeds numerous, black, narrowly obovoid, smooth.
