Dischidia

Dischidia is a genus of plants in the "dog-bane" family Apocynaceae, collectively known as the "milkweeds" (true perennial milkweeds in the Apocynaceae are found in the genus Asclepias). They are epiphytes, native to tropical areas of China, India as well as Bhutan’s southern borders, wherever minimal frost occurs. Additionally, they are known from most areas of Mainland Southeast Asia, including forested areas of Myanmar, Thailand, Vietnam, Cambodia, Laos, and some parts of Indonesia, Malaysia and Singapore. Several species are also native to Papua New Guinea, northeastern Australia, Mariana Islands and other Pacific islands....read more on Wikipedia.
