摘要

在印度，对trichosantes物种地理分布的了解不足，主要是由于缺乏修订工作。本文根据野外观察、标本收集和植物标本馆资料，描述了一个新的分类单元 - T。dunniana无性系种群。来自印度东北部西孟加拉邦锡金和北部山区的克拉凯;提出了三个东南亚分类群的首次确认记录，即dunniana亚群。dunniana和T. wallichiana亚科。来自印度东北部的海底，以及来自安达曼和尼科巴群岛的三爪鱼。中国南方trichosantes subrosea在降阶上被称为 wallichiana subsp。亚种，而三齿鼠已退化为该亚种的同义种。此外，我们还提供了这些分类群在印度的最新分布图、重要的分类注释和额外的分类特征。

A new subspecies and new records of Trichosanthes (Cucurbitaceae) for India, and notes on T. khasiana

In India, knowledge of the geographic distribution of Trichosanthes species is inadequate, largely due to the lack of revisionary work. Based on field observations, collected specimens and data from herbarium specimens, this paper describes a new taxon – T. dunniana subsp. clarkei from Sikkim and northern hill districts of West Bengal in northeastern India; and presents the first confirmed records of three southeast Asian taxa, viz., T. dunniana subsp. dunniana and T. wallichiana subsp. subrosea from northeastern India, and T. tricuspidata from the Andaman & Nicobar Islands. The name T. khasiana has been lectotypified, and Indochinese T. inthanonensis has been reduced under it. The southern Chinese Trichosanthes subrosea is transferred at reduced rank as T. wallichiana subsp. subrosea, while T. tridentata has been reduced to synonymy of this subspecies. Furthermore, we provide an updated distribution map with confirmed occurrences of these taxa in India, critical taxonomic notes and additional taxonomic characters.
