摘要

摘要对原产于中国西南部四川省的一个新品种——卧龙天麻（兰科）进行了描述和说明。它在形态上类似于中华鳖，但与后者明显不同的是，在花瓣和萼片的正轴侧有黑紫色条纹（与紫红色斑点相比），肾形表皮密被长乳头毛（与稀疏短柔毛相比），并有紫红色斑点（与未受污染相比），在伪君子的囊外有紫红色条纹（与紫红色斑点）。基于核核糖体内转录间隔区（nrITS）和36种天麻的4个叶绿体DNA片段（matK、psbA-trnH、psbM-trnD和trnL-F）的分子系统发育分析表明，卧龙线虫与纤毛虫和台湾虫亲缘关系密切。

Gastrochilus wolongensis (Orchidaceae): a new species from Sichuan, China, based on molecular and morphological data

ABSTRACT Gastrochilus wolongensis (Orchidaceae), a new orchid species from Sichuan Province, Southwest China, is described and illustrated. It morphologically resembles G. sinensis, but differs markedly from the latter in having black-purple stripes (vs. purplish-red spots) on the adaxial side of the petals and sepals, a reniform epichile densely covered with long papillate hairs (vs. sparsely pubescent) with purplish-red spots (vs. unspotted), and outside the sac of the hypochile with purplish-red stripes (vs. purplish-red spotted). The molecular phylogenetic analysis based on nuclear ribosome internal transcribed spacer (nrITS) and four chloroplast DNA fragments (matK, psbA-trnH, psbM-trnD, and trnL-F) of 36 Gastrochilus species showed that G. wolongensis was closely related to G. ciliaris and G. formosanus.

期刊介绍： Ecosystem Health and Sustainability publishes articles on advances in ecology and sustainability science, how global environmental change affects ecosystem health, how changes in human activities affect ecosystem conditions, and system-based approaches for applying ecological science in decision-making to promote sustainable development. Papers focus on applying ecological theory, principles, and concepts to support sustainable development, especially in regions undergoing rapid environmental change. Papers on multi-scale, integrative, and interdisciplinary studies, and on international collaborations between scientists from industrialized and industrializing countries are especially welcome. Suitable topics for EHS include: • Global, regional and local studies of international significance • Impact of global or regional environmental change on natural ecosystems • Interdisciplinary research involving integration of natural, social, and behavioral sciences • Science and policy that promote the use of ecological sciences in decision making • Novel or multidisciplinary approaches for solving complex ecological problems • Multi-scale and long-term observations of ecosystem evolution • Development of novel systems approaches or modeling and simulation techniques • Rapid responses to emerging ecological issues.
