NOTE

Lagerstroemia gagnepainii is only known from the type. The description with drawing in the protologue is based on a photocopy of the type collection and the accompanying flower diagnosis by Gagnepain. Lagerstroemia gagnepainii is very similar and possibly conspecific to L. duperreana , from which it seems to differ in the shape of the flower buds (globose vs subovoid in L. duperreana ). More collections are needed to determine the status of the species.
