Researchers have discovered and described a new species in the Acorus genus, named Acorus shannai, based on morphological and plastid genomic data. Led by Professor Long Chunlin from Minzu University of China, the study was published in PhytoKeys on Jan 20.
經過形態特征比較和系統發育分析，中央民族大學生命與環境科學學院教授龍春林團隊發表了一種菖蒲屬植物新物種——山柰（nài）菖蒲。該成果于1月20日在國際期刊《植物綱要》上發表。
The species was first found by students at a local vegetable market in southwestern China's Guizhou province. Cheng Zhuo, a PhD student on the team, noted its fennel-like aroma and local name Shannai, commonly planted around homes for use as a seasoning.
該物種最初是由學生在中國西南部貴州省的一個蔬菜市場發現的。團隊中的博士生程卓注意到了它的茴香香味，當地稱其為“山奈”，通常種植在家里作為調味品。
A. shannai is distinct from other Acorus species in the A. gramineus group, with key features such as a strong fennel odor and unique fruit and leaf characteristics.
山奈不同于禾草菖蒲屬的其他菖蒲屬，其主要特征是有強烈的茴香氣味和獨特的果實和葉子特征。
Professor Long explained that a "new species" is one scientifically discovered, described, and named for the first time, regardless of previous human use.
龍教授解釋說，“新物種”是指第一次科學地發現、描述和命名的物種，而不管以前人類是否使用過它。
Therefore, even if people have seen or used the plant for generations, as long as it is distinct and has not been formally published under the scientific naming conventions, it can still be classified as a new species.
因此，即使人們世世代代看到或使用過這種植物，只要它是獨特的，并且沒有按照科學命名慣例正式發表，它仍然可以被歸類為新種。
This discovery contributes to understanding Acorus genus diversity and phylogenetic relationships, while also promoting conservation efforts and ensuring the correct identification of species for consumption.
這一發現有助于了解菖蒲屬的多樣性和系統發育關系，同時也促進了保護工作，并確保正確識別供消費的物種。
