Many species of have excellent ornamental, culinary, and medicinal values. , is an ornamental and highly medicinal perennial herb endemic to the prefecture-level city of Zhangjiajie in Hunan Province, China, with a narrow geographical distribution. However, currently, it has only been assessed as a Critically Endangered species according to the IUCN classification criteria, but its conservation has not yet been studied. This study investigated the distribution and niche characteristics of , and compared the differences in growth, flowering characteristics, and soil nutrients between the wild and ex situ populations. We also analyzed the effects of soil nutrients on plant growth and flowering characteristics. During the survey, we found 274 individuals on a rock approximately 200 m from ZEFR1. Nevertheless, were still restricted in three populations, TNFP, TGM, and ZEFR in Zhangjiajie City, with a total of about 500 plants and less than 250 mature individuals. Our results show that aspects such as adverse environmental conditions, low seedling renewal rate, a lack of soil nutrients, and competition for the characteristic niche of this and other dominant plants in the natural community are the main ecological factors affecting the growth, flowering, and geographic distribution of . Based on the results of field surveys, we recommend that (1) be classified as Critically Endangered C2b and China's List of Plant Species with Extremely Small Populations. (2) Comprehensive conservation strategies were developed, such as the establishment of nature reserves, reintroduction, public education, and institutional development to provide management recommendations related to the conservation of and other endangered plants.
许多[物种名称]具有出色的观赏、烹饪和药用价值。[物种名称]是一种多年生草本植物，具有观赏性且药用价值高，为中国湖南省张家界市特有的植物，地理分布狭窄。然而，目前根据国际自然保护联盟（IUCN）的分类标准，它仅被评估为极度濒危物种，但其保护工作尚未得到研究。本研究调查了[物种名称]的分布和生态位特征，并比较了野生种群和迁地种群在生长、开花特性及土壤养分方面的差异。我们还分析了土壤养分对植物生长和开花特性的影响。在调查过程中，我们在距离ZEFR1约200米的一块岩石上发现了274株个体。尽管如此，[物种名称]仍局限于张家界市的TNFP、TGM和ZEFR这三个种群，总共约有500株植物，成熟个体不到250株。我们的研究结果表明，诸如不利的环境条件、低幼苗更新率、土壤养分缺乏以及与该物种及自然群落中其他优势植物对特征生态位的竞争等因素，是影响[物种名称]生长、开花及地理分布的主要生态因素。基于实地调查结果，我们建议：（1）将[物种名称]列为极度濒危C2b级，并列入中国极小种群野生植物名录。（2）制定综合保护策略，如建立自然保护区、进行迁地保护、开展公众教育以及加强机构建设，以提供与[物种名称]及其他濒危植物保护相关的管理建议。
