Inflorescence and flower features. Flowers solitary, or aggregated in ‘inflorescences’; in cymes, or in racemes (raceme-like), or in fascicles (or clusters). The terminal inflorescence unit cymose, or racemose. Inflorescences scapiflorous, or not scapiflorous; terminal; scape simple or branched; inflorescence 1–4 flowered, irregularly bracteate. Flowers pedicellate (erect to spreading); bracteate; ebracteolate; small to large; regular; 3 merous; cyclic; pentacyclic. Perigone tube absent. Perianth of ‘tepals’; 6; 1 -whorled; free; petaloid; without spots, or spotted; similar in the two whorls (in size and form); red (dark), or brown (or reddish-brown). Androecial members definite in number. Androecium 6. Androecial members free of the perianth; all equal; free of one another; 1 -whorled, or 2 -whorled. Androecium exclusively of fertile stamens. Stamens 6; all more or less similar in shape; diplostemonous; hypogynous, on the receptacle opposite the perianth segments; alterniperianthial. Anthers dorsifixed; versatile; dehiscing via longitudinal slits; almost latrorse, or extrorse; tetrasporangiate. Gynoecium 3(–4) carpelled. The pistil 3 celled. Carpels isomerous with the perianth. Gynoecium syncarpous; synovarious to synstylovarious; superior. Ovary plurilocular; 3 locular; sessile. Gynoecium stylate. Styles 3; free to partially joined; apical. Stigmas 3. Placentation axile. Ovules several to many; anatropous to campylotropous.

Fruit and seed features. Fruit non-fleshy; dehiscent; a capsule. Capsules loculicidal. Fruit 3 celled. Seeds endospermic. Endosperm oily. Cotyledons 1 (conspicuously coleoptile-like). Embryo straight. Testa without phytomelan.
