Quercus kerrii
Quercus kerrii is an uncommon Asian species of tree in the family Fagaceae and the "ring-cupped oak" sub-genus. It is native to Thailand and Vietnam. There are also populations in southern China that according to some authors belong to Q. kerrii but considered by others to belong to a different species, Q. helferiana.[2]

Quercus kerrii is a tree up to 20 m. tall with hairy twigs. Leaves can be as much as 240 mm long.[2][3] The acorn is oblate, 7-12 × 20–28 mm, apex depressed to flat, with a scar that is 10–20 mm in diameter and slightly convex. In China, flowering is from March–May, acorns can be found from October–November.[2]
This species and Quercus helferiana are closely related: the relationship between them and their distribution needs further work and it is possible that Q. kerrii does not occur in China.[2]
