摘要: Pampanini于 1910年发表了桔梗科采自湖北西部的一个新种 Codonopsis dracoꎮ 此后 100年无人提起它ꎮ
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. Hongꎬ 也采自湖北西部ꎮ 本文作了新组合ꎮ 刺萼参在湖北郧西的分布点已经消失ꎬ 至今仅知道陕西东
南部两个地点有少量植株ꎬ 可见刺萼参已处于濒危状态ꎮ 因为它是单种属ꎬ 对其保护应予特别关注ꎮ

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

The genus Echinocodon D􀆰 Y. Hong was de ̄
scribed as new by Hong (1984). It has been recog ̄
nized by all the relevant authors as a good genus
(Lammersꎬ 2007ꎻ Mabberleyꎬ 2008). Our recent
molecular analysis revealed that Echinocodon is not
closely related to Codonopsis as Hong (1984) indi ̄
catedꎬ but instead the closest relative of Echinocodon
is Cyclocodon (Wang et al.ꎬ 2013).
The genus is monospecificꎬ and found only in a
small area of NW Hubei and SE Shaanxiꎬ China.

Hong was collected from the suburb of Yunxi Town
in 1983ꎬ when it was locally rather abundant. How ̄
everꎬ Dr. YANG Fu ̄Sheng could not be able to find
any there in 2012 though he searched for it hard.
Luckily Dr. LI Bing found several individuals in SE
Shaanxi in 2012ꎬ and Prof. REN Yi found a few in ̄
dividuals in 2013 in Ankangꎬ also SE Shaanxi. Ap ̄
parentlyꎬ the plant is extremely endangered though
not extinct. Thereforeꎬ we should pay a special at ̄
tention on the conservation of this plant as the only
species of Echinocodon.
