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.
