Beilschmiedia Nees is a large genus containing
about 200 species， distributed mainly in tropical
regions of the worldI”．There are two species，B．fordi
Dunn and B． tsangii Merr．， recorded from Hong
Kong[2】．In the course of preparing the manuscript of
Lauraceae for Flora of Hong Kong,we have the
opportunity to re—examine the materials kept in Hong
Kong Herbarium． W e realized that Hong Kong
specimens identified as B．tsangii are diferent from
materials of B． tsangii Merr． collected from Hainan，
Guangdong， Guangxi and Yunnan， and represent an
undescribed species．Beilschmiedia glandulosa N．H．
Xia，F．N．W ei& Y．F．Deng，is described herein．The
species is similar to B．delicata S．Lee& Y．T．W ei
and B．tsangii Merr．in habit．but differs in its short
inflorescences，glandular leaves and smooth fruitsI 】
