Uses. Bark contains bitter principles allied to quassin and is used as febrifuge.

Notes. P. nepalensis Bennett differs from P. javanica Blume in being smaller trees With slender panicles and usually narrower leaflets having more elongated apices. But these characters are not constant and following King (in J. Asiat. Soc. Bengal pt. 2, Nat. Hist. 62: 228. 1893), the former is reduced to synonym of P. javanica. P. andamanica Kurz ex A. W. Bennett can hardly be distinguished from P. javanica (King l.c.).
