Leaves opposite, free to connate at base to more than halfway, triangular in cross section, flat above and rounded or keeled on lower surface, keel sometimes toothed towards apex; bluish green, usually with darker dots, glabrous or ciliate, rarely papillate on margins. Flowers axillary or terminal, solitary to many in inflorescence, usually bracteate, medium-sized. Sepals 4 or 5. Petals pink to purple, rarely white, 1-several-seriate, sometimes arranged in 5 bundles. Stamens arranged in a cone; filaments often hairy at base; staminodes few to many.

Fruit a 5(6)-locular capsule, of Ruschia type; with a deep base and no valve wings; valves opening into upright position; closing bodies small, hook- hood- or rodlet-shaped, rarely larger and sometimes 0; expanding keels short, widely diverging; additional closing rodlets at distal lower surfaces of covering membranes. Seeds variable in shape, yellowish or brownish, smooth to papillate. x = 9 ( polyploidy). F lowering throughout the year with peaks in spring and autumn.
