Vateria^ L. [Dipterocarpece). 

 In the ' Prod. Fl. Penins. Ind. Or.' i. p. 84, Dr. Wight and 

 I pointed out how V. lanceolata of Roxburgh differed from 

 the original species of the genus. Our remarks have been 

 lately confirmed by the discovery of another species aUied to, 

 but distinct from V. lanceolata, I shall here therefore divide 

 the genus into two sections or subgenera. 



I. EUVATERIA. 



Calycis lacinise obtusse, fructiferi immutatse. Petala ovalia caly- 

 cem vix superantia. ■ Stamina 40 — 50 : antherarum locuU lineares. 

 Stylus elongatus, stigma acutum. — Panicula magna, terminahs.

II. ISAUXIS. 



Calycis lacinise ovatse acutse, fructiferi grandefactse. Petala fal- 

 cata, calyce triple longiora. Stamina 15 : antherarum loculi ob- 

 longi. Stylus brevis, stigma clavatum, 3 — 6-dentatum. — Paniculse 

 axillares, folio breviores.

Section IV. Irregulares. 

 The dorsal lobe simple^ infundibuliform. Two or more 

 pointed lateral lobes, generally infundibuliform, increasing ir- 

 regularly.

The dorsal lobe is somewhat broader than deep, the dorsal 

 saddle angulose ; there are two lateral lobes ; the first is lingui- 

 form and twice the depth of the dorsal lobe. The first lateral 

 saddle is narrow and elevated much higher than the dorsal
