Wallich's figure above cited very much resembles G. cornea. My 

 plants resemble in foliage much more Q. Mangostana, from which they are 

 readily distinguished by the entire but not lobed stigma of the male flowers. 

 The flowers are very much larger than Wallich figures them, agreeing in 

 size more with the analysed flower on the plate.
