L. qiiinquevalvis is a very imperfectly known species in fruit only. 

 Tj. CoUettii is distinguished from it by the shape of its fruiting 

 calyx and by its lobes being not glabrous on the inner surface. 



Lagerstroemia Hossei, Koehne, Engler Bot. Jahrb., xlii. Beibl. 97, 

 p. 50; Hosseus, i. p. 473 et ii. p. 416.

From the description I cannot separate this species from L. 

 macrocarpa, Wall, a species which Koehne in his monograph 

 reduces to L. speciosa.
