Status: Native
Description:
Evergreen climber or scrambling shrub. Leaves opposite, variously hairy below with domatia, ovate to oblong-lanceolate; stipules ovate-lanceolate, gradually pointed. Flowers in dense axillary clusters, creamy-white, sweetly scented. Fruit in clusters, sometimes two-lobed, blackish when ripe.
Type location:
South Africa
Notes: Very similar to Keetia venosa which occurs in similar habitats though usually at lower altitudes. It can most reliably be distinguished by the stipules which in K. venosa are triangular, abruptly narrowing into a long, linear lobe. Also somewhat similar to Psydrax kraussioides. Please refer to that species for a discussion of the differences.
