Abstract

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.

伍龙麻麻(兰科):四川一新种——基于分子和形态资料的研究

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。

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.
