摘要

摘要记述了壳斗科植物Lithocarpus cadamensis Ngoc & Son的一新种，并举例说明了其分布于越南中部广义省Tra Bong区Ca Dam山。新种的特点是叶片大，叶柄长，单生和近无柄的小丘几乎完全覆盖坚果，还有多刺的小丘鳞片，这些特征明显不同于该地区已知的Lithocarpus物种，包括该地区最相似的物种，L. campylolepis, L. eucalyptus和L. gougerotae。基于全基因组snp的MIG-seq系统发育显示，该新种的系统发育位置接近桉树桉，并具有多种形态特征。本文提供了新种的形态描述和与近缘种的比较、照片、线条图、初步保存状况和DNA条形码序列。

A New Species of Lithocarpus (Fagaceae) from Ca Dam Mountain of Quang Ngai Province, Vietnam

Abstract Lithocarpus cadamensis Ngoc & Son, a new species of Fagaceae, is described and illustrated from Mt. Ca Dam, Tra Bong District, Quang Ngai Province, central Vietnam. The new species is characterized by its large leaf blades with long petioles, solitary and subsessile cupules which almost completely cover the nut, and spiny cupule scales, in a combination that clearly differs from the previously known species of Lithocarpus including the most similar species in the region, L. campylolepis, L. eucalyptifolius, and L. gougerotae. A MIG-seq phylogeny based on genome-wide SNPs reveals a phylogenetic position close to L. eucalyptifolius, from which the new species is differentiated by multiple morphological characters. A morphological description and comparison with related species, photographs, line drawing, preliminary conservation status, and DNA barcode sequences are provided for the new species.
