Vateria, L. {DipterocarpecB), 

 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 ariother species allied to, 

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

 the genus into two sections or subgenera. 



I. EUVATERIA. 



Calycis laciniae obtusse, fructiferi immutata?. Petala ovalia caly- 

 cem. vix superantia. Stamina 40 — 50 : antherarum loculi lineares. 

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



1. V. Indica, Linn. Wight et Am., 1. c. 



II. ISAUXIS. 



Calycis laciniae ovatse acutae, fructiferi grandefactae. Petala fal- 

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

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

 axillares, folio breviores. 



2. V. lanceolata (^o^h.) ; foliis lanceolatisbasi acutis. Roxb.Fl.

3. V. Roxhurghiana (Wight Mss.) ; foliis oblongis basi retusis vel

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
