Synonyms: Croton barotsensis Gibbs
Croton seineri Pax
Common names: Barotse Croton (English)
Frequency: Rare and very local in Zimbabwe.
Status: Native
Description:
Shrub or tree, often multi-stemmed and with drooping branches. Bark smooth blotched grey and white. Leaves elliptic-ovate, 3-14 cm long, single-veined from the base, densely stellate hairy on both surfaces when young, becoming more or less hairless above when older; margins glandular crenate-serrate; petiole 1.5-6 cm long with 2 orange discoid glands at the apex. Leaves often turning orange to red before falling. Inflorescences 6-20 cm long, terminal on main branches or short lateral shoots. Flower mostly unisexual, sometimes on the same tree or on different trees, creamy or greenish-yellow, scented. Fruit subglobose or obovoid, 9-14 mm long, slightly 3-lobed, scruffy stellate-hairy, yellowish to buff-coloured when ripe, edible.
Notes: Similar to Croton leuconeurus but distinguished by the leaves that clearly have a single midrib and are not three-veined from the base. Also the inflorescences are longer and the fruit is much smaller and densely clustered.

Habitat: In riverine vegetation, often overhanging the water, on sandy banks and in swampy river margins.
Altitude range: (metres) 890 - 930 m
