摘要: 通过对云南百部(Stemona mairei(H.Lév.)K.Krause)及其形态相似种金沙江百部(S.jinshajiangensis X. D. Cong et G. J. Xu)和变种滇北百部(S.jinshajiangensis var.dianbeiensis X. D. Cong et G. J. Xu)模式标本采集地野外居群植株的实地调查和研究,发现金沙江百部及其变种滇北百部的形态特征变异式样均在云南百部形态特征的正常变异范围内,因此将金沙江百部及其变种处理为云南百部的异名,同时对云南百部的形态特征进行了补充描述。结合对云南百部6个野生居群成熟植株的开花结实特征、种子传播策略分析,对云南百部受威胁状况进行了评估。Abstract: We investigated specimens and wild populations of Stemona mairei (H. Lév.) K. Krause, and combined field observations of individuals from the locations of the type specimens of S.jinshajiangensis X.D. Cong et G.J. Xu and S.jinshajiangensis var. dianbeiensis X.D. Cong et G.J. Xu. Results showed that the variation in morphological characteristics of S.jinshajiangensis and S.jinshajiangensis var. dianbeiensis were within the normal profile of S. mairei. Therefore, we suggest that S.jinshajiangensis and S.jinshajiangensis var. dianbeiensis should be defined as synonymies of S. mairei. A supplementary morphological description of S. mairei is provided according to the six wild populations. We also briefly evaluated the threatened status of S. mairei and its potential as a medicinal resource based on our preliminary study of its flowering, fruiting, and seed dispersal tactics.
