A well-defined species with leaves which recall those of Quercus Prinos Linnaeus. 

 In the shape and serration of the leaves it resembles E. bengalensis Hooker f., 

 which is easily distinguished by the glabrous lower surface of the leaves. From 

 E. japonica Lindley and E. grandiflora it differs distinctly in the structure of its 

 ovary which is adnate to the calyx-tube only in the lower half, the upper free part 

 being densely villose, while in the former two species the ovary is entirely inferior 

 and glabrous at the apex. The presence of two or three styles nearly free or con- 

 fluent to above the middle is interesting and further proves the instabiUty of this 

 character in the genus.
