Quercus augustinei, spelling corrected from Quercus augustinii,2 is a rare species of tree in the beech family Fagaceae. It has been found in Vietnam as well as Guangxi, Guizhou, and Yunnan Provinces in southern China.3 It is placed in subgenus Cerris, section Cyclobalanopsis.4

Description

Quercus augustinei is a tree up to 10 m tall, with orange-brown twigs and leaves as much as 120 mm long. The acorn is oblong-ovoid, 10–17 × 8–12 mm, glabrous, apex rounded or slightly depressed; scar approx. 6 mm in diameter.35

Taxonomy

The species was first described in 1899 by Sidney Alfred Skan. Skan spelt the specific epithet augustinii. This was intended to commemorate the collector, Augustine Henry. Under the International Code of Nomenclature for algae, fungi, and plants, this spelling is not an acceptable Latinization of "Augustine", and was corrected to augustinei. Another possible correction would be augustini.2
