The small leaved white cross berry (Grewia tenax [Forssk.] Fiori) is a fruit-producing deciduous shrub or small tree of widespread occurrence in semi-arid and sub-humid tropical climates. Despite its well-recognized potential and high prices on local markets, there are no commercial plantations in Sudan. Wild plants have continuously been used to meet the growing commercial demand for their fruits. Recently, there has been an increased interest in finding alternative, potentially high-value cash crops to improve the income of small farmers who are currently depending upon growing and selling millet (Pennisetum glaucum [L.] R. Br.), sorghum (Sorghum bicolor [L.] Moench), sesame (Sesamum indicum L.), and groundnut (Arachis hypogaea L.). G. tenax has often been cited as a prime candidate for domestication as a useful horticultural plant. One major factor hampering this development is the limited and scattered knowledge available on this species. The purpose of this paper is to highlight the importance of G. tenax by providing information on its botanical and horticultural characteristics in the effort to promote its domestication and commercialization for regional and global markets.
