Notes — 1. Lagerstroemia celebica is here widely conceived as it appeared impossible to the authors to discriminate between the many taxa which are at present put into synonymy. In our opinion the synonyms of widespread L. celebica are the reflexion of the, often local, variation mainly in the elaboration of the ridges on the calyx tube and (in bud) the ornamentation on the sutures of the calyx lobes. As yet we cannot trace and reproduce the distinctions as propounded by Furtado & Srisuko (1969). Possibly in the future, when more material from all areas may have become available, and especially by fieldwork, a more obvious division could be discerned.

In New Guinea noteworthy variation in fruit is seen: the collection Millar NGF 23520 (Northern Province) deviates in having a long smooth pseudopedicel, to 10 mm long, and Takeuchi & Kulang 11513 (Gulf Province) deviates in having small fruits c. 10 mm long with only 4–5 valves. These collections link up with L. celebica , in a broad sense, but more similar collections are needed for assessing a possibly different taxonomic status. 2. The species L. paniculata and L. pterosepala are accepted in the present treatment; they link up with forms of L. celebica with pronounced ridges on the calyx tube and sepal sutures, but in the former two species the wings on the sepal sutures (in bud) are much more obvious.
