Common names: white raisin Eng. It is a frost-resistant, hardy shrub or small tree that is adaptable to all soils, from clay to sand, and does not require much water. Grewia bicolor is a multi-stemmed shrub or small tree, up to 9 m high.
Its bark is smooth, grey, becoming dark grey and deeply fissured and peeling away in straps with age. The young branchlets are velvety grey or brown. The leaves are alternate, simple and elliptic to slightly ovate, x mm, with a broadly tapering to rounded apex. They are 3-veined from the asymmetrically lobed base, rounded to slightly cordate, held horizontally or drooping, glossy green above, almost white and silvery hairy below, while the margins are entire to slightly serrated.
The petiole leaf stalk is about mm long. The flowers are small, bright yellow, borne in axillary clusters at the end of branches. They are often borne in profusion, with sepals up to 12 mm long and petals shorter. The flowering time is October-March. The fruits are round and fleshy drupes fruits such as plums , reddish brown or orange and black when ripe, entire or deeply 2-lobed, up to 6 mm in diameter.
According to Raimondo et al. Grewia bicolor naturally occurs in dry deciduous woodland and bushveld. It is frequently associated with mopane at low altitudes, on sandy flats and rocky mountain slopes. It is also occasionally found at medium altitudes in higher-rainfall areas.
The genus Grewia was named after Nehemiah Grew , an English physician. The specific name bicolor refers to bicoloured leaves. The white raisin is often associated with termite mounds and riverine fringes, especially at medium altitudes in higher-rainfall areas. The leaves are browsed by game and livestock. The fruit is edible, sweetish but astringent. The roots are also used to treat chest complaints. Grewia bicolor is a most variable species, probably because it freely hybridises with G.
These trees grow best in temperate climates with summer rainfall. They do not require much water and are frost-hardy. Grewia bicolor forms a distinct shrub layer below the tree canopy. Mothogoane M. National Herbarium, Pretoria September Login to add your Comment Not registered yet?
