Sepals 5, free, subequal, often spathulate, herbaceous. Corolla regular, widely campanulate, deeply 5-lobed; lobes induplicate-valvate or slightly imbricate. Stamens shorter than the corolla; filaments filiform; anthers small-pollen smooth. Disk small, cupular. Ovary deeply 2-lobed, each lobe with 2 ovules' styles 2, filiform, gynobasic (inserted between the lobes); stigmas capitate. Capsule 2-lobed; lobes erect, 1-or rarely 2-seeded, indehiscent or irregularly 2-valved Seeds subglobose, smooth.

Sepals joined basally, ± equal, becoming enlarged in fruit. Corolla campanulate, ± equal to calyx, lobed to middle or below. Stamens included; pollen not spiny. Ovary deeply 2-lobed, each lobe with 2 ovules. Styles 2, gynobasic, free, filiform; stigmas capitate. Capsule irregularly 2-valved or indehiscent, apically rounded, truncate, emarginate, or deeply 2-lobed. Seeds 1 or 2 per lobe, subglobose, smooth.
