attached near the top of the corolla- tube ; anther-cells distinct, narrowly 

 oblong, pendulous. Capsule oblong, flattened parallel to the septum, 

 septicidally 2-valved. Seeds thinly discoid, completely surrounded (except 

 at their base) by a hyaline entire wing. Species 3, 2 in Malaya, 1 in 

 Assam. 



The Malay species, on which the genus is founded, are described and figured with 

 5 fertile stamens, having the anther-cells combined. The Assam species constitutes u 

 marked sub-genus.
