Core Viewpoint - Researchers from Guizhou University have discovered a new species of the genus Weigela, named Daluoshan Weigela, in the Dasha River National Nature Reserve, marking a significant addition to the biodiversity of the Rosaceae family [1] Group 1 - The new species was found in July 2024 at an altitude of approximately 1900 meters, growing in sandy soil with ample sunlight, with around 50 individuals observed [1] - Initial observations did not reveal flowering or fruiting, but by late October of the same year, the plant was confirmed to be in a flowering and fruiting state [1] - The new species exhibits clear differences from all known Weigela species, confirming it as an unrecorded species [1] Group 2 - The Weigela genus is a small group within the Rosaceae family, with 18 species recorded globally and 10 species in China, primarily distributed in the southwestern region [1] - The last new species in the Weigela genus was reported 35 years ago, highlighting the significance of this discovery [1] - The Daluoshan Weigela is the only known climbing plant in its genus, enriching the species and genetic diversity of Weigela [1]

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].
