Narrow leaved wild sweet-pea

Shape of terminal leaflet distinguishes V. vexillata from V. unguiculata (Pooley). The longer hairless leaves and less hairy calyx indicates V. v. var. angustifolia rather than V. v. var. vexillata . Doubt if the varieties are distinct.

See descriptions in Flora of Zimbabwe var. vexillata and var. angustifolia.
