SUMMARY
Rhynchosia rufescens is a perennial trailing sub-shrub. It flowers during September-February. The flowers are hermaphroditic, self-compatible and have explosive pollination mechanism principally adapted for melittophily. The plant is facultative xenogamous but autogamy essentially requires vectors. Pods dehisce explosively to disperse seeds. Re-growth from root stock and propagation by seed together contribute to build up its populations in soils with sufficient moisture and nutrients.
