Note.

Camus (1935) described Quercus blaoensis based on the specimen Poilane 22372 from Vietnam. The authors examined specimens of Poilane 22372 in P ([P00754000], [P00753999]) and the digitised images of the specimens in K ([K000832201, K000832202, K000832203, K000832204]) and G [G00358072]. Amongst them, only two specimens in P are fertile and only P00754000 represents diagnostic traits of a nut with cupule. Thus, the specimen Poilane 2237 2 deposited in P [P00754000] was selected as the lectotype for Q. blaoensis .
