White Bauhinia

Bauhinia acuminata is a species of flowering shrub native to tropical southeastern Asia. The exact native range is obscure due to extensive cultivation, but probably from Malaysia, Indonesia (Java, Borneo, Kalimantan, Lesser Sunda Islands), and the Philippines. An extremely widespread species, with only the general threats of associated habitat loss and degradation as a result of expanding human populations. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2011).
