[Sfej)wnoporus. 



[V. indica^ L. (V. malabarica, Bl.) does not occur in Ceylon. Yet 

 Linnitus (see Fl. Zeyl. No. 204) partially based the species on a specimen 

 in Hermann's Herbarium. This, however, cannot now be discovered 

 there (see Journ. Linn. Soc. xxiv. 143). The species is figured, under the 

 name V. inalabanca, in Bedd. Fl. Sylv. t. 84 ; it affords the ' Piney 

 varnish' or 'white Dammar' of S. India.]

This genus is reduced to Vateria in the Fl. B. Ind. and to Vatica by 

 A De Candolle. It has, however, as good claims to independence as 

 many others in this family.
