By Someleze Gcuwa

Family: Vitaceae (Grape family) Common names:Engl. Common Forest Grape, Monkey-rope, Simple-leaved Grape, Wild Grape, Wild Vine
Afr. Bobbejaantou, Bosdruif, Bosdruiwe, Wildedruif, Wildedruiwe
Xho. Chithibhunga

Robust canopy climber or small scrambling tree; Bark is greyish; young branchlets with thick rusty hairs, becoming hairless with lenticels; tendrils velvety. Leaves are almost circular to kidney-shaped, slightly 3-lobed, dark green above, dense with brownish rusty soft hairs below. Flowers are small in dense axillary heads, yellowish green, densely furry with rusty hairs when in bud (October-January). Fruit almost spherical, fleshy, becoming red and finally purplish black (January-April).

Conservation status
According to the SANBI (South African National Biodiversity Institute) Red list of South African Plants, Rhoicissus tomentosa was not selected in any one of four screening processes for highlighting potential taxa of conservation concern for detailed assessment and was hence given an automated status of Least Concern (L.C.). The Threatened Species Programme is currently systematically completing full assessments for all taxa with an automated status. 

Distribution and habitat
This common forest grape occurs in riverine fringes, clambering over trees and bushes and almost associated with forest. Provincial distribution: Eastern Cape, KwaZulu-Natal, Limpopo, Mpumalanga and Western Cape.

Derivation of name and historical aspects
The genus Rhoicissus is derived from the Greek rhoia, meaning pomegranate and kissos, ivy. Perhaps not the most accurate of names: like ivy, it is a climber, but it has tendrils; and the small fruits, although spherical, do not seem very like that of pomegranate. The Latin species name tomentosa means felt-like, with a dense woolly covering, and alludes to the rust-coloured hairs that cover the young growth, the underside of the leaves, buds and tendrils.

The name Chithibhunga derives from ukuchitha, to destroy, and ukubhunga, to plot or plan, meaning to overcome malevolent forces aimed at the user.

R. tomentosa fruits are eaten by birds and mammals and leaves are browsed by game. The fruits are said to be particularly popular with Knysna turaco (Tauraco corythaix) and Purple-crested turaco (Tauraco porphyreolophus). Swollen tubers, although toxic, are eaten by bush pigs and porcupines. Silver-striped Hawkmoth caterpillar (Hippotion celerio) have been recorded eating the leaves of R. tomentosa and R. tridentata.

Uses and cultural aspects
The fruits are grape-like in appearance and edible, according to the naturist Swynnerton, ‘not up to much’. When boiled with plenty of sugar they are said to make a delicious conserve and an excellent jelly. Split branches have been used as a rope tying thatch and also in basket-making. The roots boiled with milk are given calves to expel intestinal worms.

Other people used it as a ritual wash and as an emetic for good luck and protection against the witchcraft and evil spirits. It is also used as a steam treatment to ensure good fortune. A small piece is held in the mouth for protection at times of vulnerability such as during court cases.

Growing Rhoicissus tomentosa

Rhoicissus tomentosa is easy grow and has ornamental foliage, both in shape and colour, giving interest throughout the year. It is easy to grow from seed and cuttings taken in spring or summer. Plant rooted cuttings or sturdy seedlings in a shady spot below shrubs or trees where it can ramble. It can be used to cover a wall but will need a trellis of some sort so the tendrils will have something on which to cling. It is also attractive over a pergola or fence. It can be grown indoors – being a forest dweller it can adjust to low light. Water regularly until well established and use mulch and compost to retain moisture and ensure strong, healthy growth.
