摘　　要：在多次野外调查、标本采集及大量文献查阅的基础上,我们确定了叶下珠科(Phyllanthaceae)1种中国新记录植物——多支守宫木(Sauropus racemosus Beille)。其为多年生常绿灌木,枝叶无毛,叶片膜质,总状花序3~5支聚生于老茎下部的小枝脱落处,蒴果扁球状,红色,果皮6爿裂,极易与守宫木属其他种区分,因其多支花序聚生于老枝而取名为多支守宫木。该文详细描述了多支守宫木的形态特征,并提供了植物彩色照片、分布信息,并基于IUCN的评估标准对该种的濒危等级进行了评估。多支守宫木的发现再次丰富了中越边境地区植物物种的多样性,不仅体现了中越边境地区是全球生物多样性热点地区和生物多样性保护的关键区域,同时也体现了该地区的植物调查尚不够充分,还需进一步深入调查研究。Based field works,specimen collections and lots of literatures reading,we found a newly recorded species of Phyllanthaceae from China——Sauropus racemosus Beille.It differs from other species of Sauropus in having glabrous young branches,glabrous leaves,racemoses 3 to 5 clustered on the lower part of the old stem branchlets.In this paper,a detailed description,color photographs and geographical distribution of S.racemosus are given.In addition,we consider S.racemosus as‘Endangered’(EN)based on the IUCN categories and criteria.The discovery of S.racemosus enriched the diversity of plant species in the Sino-Vietnanese border area.It reflects that the Sino-Vietnanese border area are biodiversity hotspots in the world and key areas for biodiversity conservation.It also shows that the plant investigation in this area is not enough,and further investigation and research are needed.
