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.
经过形态特征比较和系统发育分析，中央民族大学生命与环境科学学院教授龙春林团队发表了一种菖蒲属植物新物种——山柰（nài）菖蒲。该成果于1月20日在国际期刊《植物纲要》上发表。
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.
该物种最初是由学生在中国西南部贵州省的一个蔬菜市场发现的。团队中的博士生程卓注意到了它的茴香香味，当地称其为“山奈”，通常种植在家里作为调味品。
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属的其他菖蒲属，其主要特征是有强烈的茴香气味和独特的果实和叶子特征。
Professor Long explained that a "new species" is one scientifically discovered, described, and named for the first time, regardless of previous human use.
龙教授解释说，“新物种”是指第一次科学地发现、描述和命名的物种，而不管以前人类是否使用过它。
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，即使人们世世代代看到或使用过这种植物，只要它是独特的，并且没有按照科学命名惯例正式发表，它仍然可以被归类为新种。
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.
这一发现有助于了解菖蒲属的多样性和系统发育关系，同时也促进了保护工作，并确保正确识别供消费的物种。
