Near Q. polystachja Wall. (King. t. 44), from which the present 

 plant is quite distinguishable by the shape of glans which is ovoid, 

 acute at the apex and round at the base. Also very like Q. thalassica 

 IIance, but differs from it by the smaller cups with more elevated cen- 

 tral scars, and more obscure marginal rings, and by the larger leaves.
