摘要

Capparis glabrata是属于Monostichocalyx科的一个新种。该种产于柬埔寨磅湛省和茶胶省。该新种是一种灌木，其特征是小枝无毛，托叶刺笔直或稍下弯，叶片无毛，先端锐尖或圆形，腋上行连续开花，花瓣黄色，子房椭圆形，被微柔毛，柱头呈球状。它与产于泰国和老挝北部的 C. echinocarpa 有亲缘关系。本文讨论了该新种与相关类群的亲缘关系，并为柬埔寨已知的所有 Capparis 种提供了检索表。其保护状况暂时被评估为易危（VU）。

A new species of Capparis (Capparaceae) from Cambodia

Capparis glabrata, a new species belonging to sect. Monostichocalyx, is described from the Kampong Cham and Takeo Provinces of Cambodia. The new species is a shrub characterized by glabrous twigs, straight or slightly recurved stipular thorns, glabrous leaf blade with apex acute or rounded, serial flowers in supra-axillary rows, yellow petals, and ellipsoid, puberulous ovaries with a knob-shaped stigma. It is related to C. echinocarpa, a species occurring in Thailand and northern Laos. The affinities of the new species to related taxa are discussed and a key is provided for all species of Capparis known from Cambodia. The conservation status is provisionally assessed as vulnerable (VU).

期刊介绍： Since 1931, Brittonia, assuming the broadest possible definition of the field of systematic botany, has been an important outlet for the publication of original research articles on anatomy, botanical history, chemotaxonomy, morphology, paleobotany, phylogenetic systematics, taxonomy, and phytogeography. Each issue contains articles by the staff of The New York Botanical Garden and outside contributors, book reviews, and announcements.
