贵州发现新物种“大娄山绣线梅”

Core Viewpoint - A new species of climbing plant, named "Daluoshan Xiuxianmei," has been discovered in the Dasha River National Nature Reserve in Guizhou, marking a significant addition to the Rosaceae family and the only known climbing species in the genus [1][2]. Group 1: Discovery and Research - The new species was identified during a scientific survey organized by the National Forestry and Grassland Administration and the Guizhou Provincial Forestry Bureau [2]. - The discovery challenges the long-standing classification of the genus, which has been recognized primarily as upright shrubs, thus enriching the species and genetic diversity within the group [2]. - The research was published in the international plant taxonomy journal "Plant Keys" on August 15 [1]. Group 2: Characteristics and Habitat - "Daluoshan Xiuxianmei" was found in two field investigations, with approximately 50 specimens located at an altitude of about 1900 meters, in sandy soil with ample sunlight [6]. - Initial observations did not reveal flowering or fruiting, but subsequent investigations confirmed the plant's reproductive state, highlighting its distinct morphological and molecular characteristics compared to known species [6].
