Authors: Ren Sa & Michael G. Gilbert

Luorea Necker ex J. Saint-Hilaire; Maughania J. Saint-Hilaire.

Shrubs or subshrubs, rarely herbs, erect or trailing. Leaves digitately 3-foliolate or simple; stipules persistent or caducous; stipels absent; leaflets usually with sessile glands abaxially. Inflorescence axillary or terminal, racemose or compound racemose, rarely paniculate or capitate. Bracts 2-columned; bracteoles absent. Calyx 5-lobed; lobes narrow and long, lower one longest; tube short. Corolla longer than calyx or included; standard oblong or elliptic, base clawed, with auricles; wings very narrow, auriculate. Stamens diadelphous; vexillary stamen free; anthers uniform. Ovary subsessile; ovules 2; style filiform, glabrous or slightly hairy; stigma small, capitate. Legume elliptic, dehiscent, inflated, not septate. Seeds 1 or 2, almost orbicular, without strophiole.

About 30 species: tropical Asia, Africa, Oceania; 15 species (two endemic) in China.

The generic synonym Maughania is very often written incorrectly as "Moghania."
