摘要:

Pampanini于1910年发表了桔梗科采自湖北西部的一个新种Codonopsis draco。此后100年无人提起它。最近作者在进行党参属及其近缘类群的专著研究中发现它就是1984年发表的刺萼参Echinocodon lobophyllus DY. Hong, 也采自湖北西部。本文作了新组合。刺萼参在湖北郧西的分布点已经消失,至今仅知道陕西东南部两个地点有少量植株,可见刺萼参已处于濒危状态。因为它是单种属,对其保护应予特别关注。

关键词: 刺萼参, 新组合, 单种属, 濒危状态

Abstract:

Codonopsis draco was described by Pampanini as new from NW Hubei [HuPeh] Province, China. This species has been ignored since then by all late authors; even Lammers failed in mentioning it. Recently when the present author traced the name of Cdraco Pamp., he found from the figure provided by Pampanini that it is a distinct species but not in Codonopsis. By comparing it with species of Codonopsis and its allies it was found conspecific with Echinocodon lobophyllus DY. Hong, which was described based on a collection also from W Hubei (Fig1). A new combination is made here in the present paper.

Key words: Echinocodon draco, New combination, Endangered state
