There are often produced in the leaf-axils hard pale-green finely 

 lobulated and rounded masses viscous on the surface and formed of 

 crowded coral-like abortive branches. These may be of similar cha- 

 racter to those on Hopea Wighiiafia, Wall, as figured in Wight, 111. t. 37. 

 Var. /3. may be a separate species.
