Notes — 1. Lagerstroemia ovalifolia differs from all other Malesian species in having (6–)7–9 calyx lobes (sepals), 6 in the other species.

2. Furtado & Srisuko (1969) had a different conception of L. ovalifolia as the present authors, who convey part of it, namely var. apiculata , var. riedeliana , and var. novoguineensis , to L. celebica .

3. In herbarium specimens the leaves below are sometimes conspicuously dark chocolate-coloured, contrasting with the upper surface.
