    In southern Africa it mostly occurs in drier areas than T. dregeana; usually in riparian forest but also locally in woodland and wooded grassland on and in scrub forest in rocky places. In Natal it occurs in coastal forest from Mtunzini northwards, whereas T. dregeana occupies that habitat further south.

    Distribution

    Widespread in tropical Africa from Senegal to the Red Sea and the Yemen, and through East and Central Africa to the Caprivi Strip, Botswana and Natal. In the Caprivi Strip and Botswana it is a characteristic member of riparian forest fringing the Zambezi and Chobe Rivers.
