孟连苞叶兰(兰科)的重新发现与形态特征增补
Rediscovery of Brachycorythis menglianensis ( Orchidaceae) with additional descriptive notes
摘要
Abstract
Brachycorythis menglianensis has not been discovered again since it has been firstly published in 2001. Until now, it has been only known from the illustration and type specimen. However, characteristics of plants and flowers were described not enough in the original description because of shrunk specimen, which led to be treated as the synonym of B. henryi by Henrik ? Pedersen. During our field investigation in the Menglian County, South Yunnan, China, we fortunately found one population of B. menglianensis. After comprehensive observation for plant and flower characters using the fresh materials, the results showed that B. menglianensis significantly differed from B. henryi by having ovate and smaller size ( 2. 5-4. 7 × 1. 7-2. 3 cm) leaf, labellum densely papillate adaxially and apex emarginated or 2-lobe. Therefore, we believe that these morphological features represent significant differences for species delimitation and hence reinstate B. menglianensis as a distinct species. Meanwhile, we present more detailed information of morphological characteristics, habitat and survival situation of this species in this paper.关键词
