NOTE

In the treatment of De Wilde & Duyfjes (2013: 93) Lagerstroemia duperreana was segregated into two varieties, viz. var. duperreana , and var. saxatilis W.J.de Wilde & Duyfjes. Of these only var. duperreana is known from Cambodia, Laos and Vietnam. As the variety saxatilis is found in sandstone areas in Thailand ( Ubon Ratchathani Province) very near the Cambodian border it may possibly occur in Cambodia.
