Lao name, Puey Pluak bang (ex Luang Vanpruk). Siamese 

 name, T'Bek (Ta baak) ex Kerr. 



Kerr's specimens in fruit only are referred doubtfully to this 

 species.

Lao name, Sow (ex Luang Vanpruk). 



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

 L. Collettii 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. 



Doi Sootep, Hosseus (ex Koehne). 



From the description I cannot separate this species from L. 

 macrocarpa, Wall, a species which Koehne in his monograph 

 reduces to L. speciosa. 



Lagerstroemia intermedia, Koehne, var. oblonga, Craib, a typa 

 foliis oblongis, apice truncatis vel rotundatis breviter acum- 

 inatis, nervis nervulisque supra prominulis, reticulatione haud tarn 

 tenui, alabastris floribusque paullo majoribus recedit. Craib, Kew 

 Bull. 1911, p. 53. 



Chiengmai, in eng jungle, 300 m., Kerr, 578. 



To this probably also belongs Luang Vanpruk, 200 from Phre 

 for which the Lao name Puey is given.
