This genus seems to be closely allied to Ixora, witli which it agrees 

 in habit and general appearance, differing however in its fleshy, prism- 

 shaped, corolla-segments, which are vakate in estivation, its included 

 stamens, and in the form of its seeds. It is perhaps more nearly allied 

 to Cantldum. It occurs rather sparingly in the Ambagamowa District 



of the Central Province;
