The most striking trees in the forest region are, in the basin of the Cavalla, the giant Funtumia elastica, which grows to an altitude of 200 ft.; various kinds of Parinarium, Oldfieldia and Khaya; the bombax or cotton tree, giant dracaenas, many kinds of fig; Borassus palms, oil palms, the climbing Calamus palms, and on the coast the coconut.
The bombax or silk-cotton tree attains gigantic proportions in the forests, which are the home of the indiarubber-producing plants and of many valuable kinds of timber trees, such as odum (Chlorophora excelsa), ebony, mahogany (Khaya senegalensis), African teak or oak (Oldfieldia africana) and camwood (Baphia nitida).
In southern Kordofan and in the higher parts of the Bahr-el-Ghazal the silag and ebony are also common, as well as African mahogany (homraya, Khaya senegalensis) and other timber trees.
