Quercus asymmetrica [3] is an oak tree species in the beech family Fagaceae. [4] [5] It is found in China (specifically, Guangxi Province and Hainan Province, where it is called 托盘青冈 tuo pan qing gang) and northern Vietnam. [6] It is placed in subgenus Cerris, section Cyclobalanopsis. [7]
Quercus asymmetrica is a tree growing up to 15 m tall, with branchlets that are conspicuously angular when young; by second year, they become glabrous with occasional lenticels. The leaves are leathery, elliptic to ovate-lanceolate, 50-120 × 25–60 mm and have 9-11 secondary veins on each side of mid-vein. The acorns are oblate, 25–28 mm in diameter, greyish-brown, with a scar 15–20 mm in diameter, impressed or flat. The cupules are 20–30 mm in diameter. A persistent stylopodium is approximately 40 mm in diameter. In China, flowering is in May–June and acorns may be found in October–November of the following year. [8]
