Introduction

A new species of sclerophyllous oak, Quercus pseudosetulosa (section Ilex), from Dawanshan Island in Guangdong, China, was described by Li et al. (2018).1 The holotype (CSH0140813) is deposited at the Herbarium of Shanghai Chenshan Botanical Garden (CSH). It is distinguished from Q. setulosa and Q. bawanglingensis by its thickly leathery leaf blades with recurved ma and flat, glabrous, glossy surfaces. During our field survey, only one population with 2 subpopulations (about 40 mature individuals in each subpopulation) were found near the top of the southern open rocky slopes of the isolated hills of Dawanshan Island, near the Zhujiang River estuary. The habitat of the 2 occurrence sites on the island covers a range of about 450,000 m2 between 113° 43' 0.96" E / 21° 56' 58.15" N and 113° 43' 48.22" E / 21° 56' 47.02" N, 27-100 m altitude).
