A small erect glabrous herb. St em about 6 in. high, simple or diffusely 

 branched, 4-eided. Leaves sessile or the lowermost very shortly 

 stalked, 4-1 in. long, oblong or oblong-lanceolate, entire or slightly 

 serrate, 1-5 nerved irtm the bhse. Flowers axillary and in terminal 

 racemes, filiform. Calyx ^- in. long, deeply divided ; segments 

 linear-lanceolate, acute. Corolla twice BP Ici.g as the calyx, blue cr 

 white. Capsule ovoid-c.blorg, acute, usually exceeding the calyx. 



Common within the area in wet ground, flowering during the rainy 

 season. DISTEIB.: Throughout' the greater part of Incia, but not in 

 Ceylon, extending to Siam and Trop. Africa. Very similar in general 

 appearance to Vandellia pyxidaria, but the shorter stamens reduced 

 to staminodes and the longer and acute capsules distinguish it from the 

 latter.
