Widespread in Africa including the southern Cape, Guinea and Madagascar, through southern Asia into China, in South Malesia and the northern states of Australia; in Malesia: Malay Peninsula (Langkawi, on limestone rocks), Java (in the western half only on the Northcoast, in E on both sides; also Madura and Kangean Is.), Lesser Sunda Is. (Lombok, Sumba, Sumbawa, Flores, Timor), and SE. Moluccas (Tenimber Is.). The range in Malesia is distinctly disjunct on both ends which is due to its drought preference; it is absent from the Sundaland rain-forest core.
