 more rarely 3 expanded in a venose oftener petiolate and coloured 

 membranous leaf; the rest or more rarely all {Oreopolus ^) shorter 

 unequal, entire or dentate. Corolla hypocrateriform ; tube elongate ; 

 throat glabrous or pubescent; lobes 4, 5, valvate, finally reflexed. 

 Stamens 4, 5, inserted in throat of corolla ; anthers enclosed or semi- 

 exserted. Germen 2-celled ; disk epigynous depressed ; branches of 

 slender style ^ 2 stigmatose, shorfc revolute. Ovules in cells 2,-^ 

 collaterally ascending ; incompletely anatropous ; micropyle extrorsely 

 inferior, finally lateral ; a spurious incomplete septum ^ sometimes 

 produced between each ovule. Fruit capsular, crowned more or less 

 with accrete calyx; valves 2-4, solute from, membranous septum.
