摘要
Artabotrys rubriflorus sp. nov. is described as a new species of Annonaceae, collected from Malipo, Yunnan province, China. It can be distinguished from the other nine species of Artabotrys by its red petals and stamens, as well as its reduced number of carpels per flower (7–9), fewer monocarps per fruit (4), and the presence of 1–2 seeds within each monocarp. The specimens of this new species were gathered through fieldwork and were subsequently subjected to rigorous analysis using both classical taxonomical methods and molecular phylogenetic analysis. The phylogenetic reconstruction, based on four chloroplast DNA regions (matK, rbcL, trnLF and psbAtrnH), was carried out employing maximum parsimony, maximum likelihood and Bayesian inference approaches. These analyses confirmed the systematic positioning of Artabotrys rubriflorus sp. nov. within the genus Artabotrys , while also establishing its distinctiveness from other species. Additionally, a comprehensive and detailed description of the new species, along with a key for identification, is provided.
