| 摘要: |
| 金粟兰属(Chloranthus Swartz)是研究被子植物起源和早期演化的关键类群之一,部分种类被广泛地栽培和使用。虽然前人已对该属植物的形态、地理分布、分类、系统发育、化石和化学成分等开展了丰富的研究,但是通过作者持续广泛的调查研究发现,以往对该属植物形态多样性、生活型和地理分布的认识仍不充分,且在该属植物中还存在分类观点不统一、名实混淆、沿用错误分类信息等问题。该研究在广泛查阅标本资料和长期野外调查的基础上,对金粟兰属植物的形态多样性、生活型和地理分布格局进行了较为全面的描述。结果表明:在形态方面,金粟兰属内花部器官尤其药隔形态在种间呈多样性而种内相对稳定,是物种划分最有效的分类性状,其中网脉金粟兰药隔形态变异较大,疑为复合群; 在生活型方面,狭叶金粟兰与网脉金粟兰为常绿草本,区别于该属其他常绿亚灌木以及地上部分每年秋冬季节枯萎的多年生草本种类; 在地理与生境分布方面,验证了金粟兰属内最近缘的4个长药隔草本物种间的确呈显著水平替代分布格局,而一直被认为只分布在湖北宜昌和重庆奉节等地的狭叶金粟兰却在贵州亦有分布。该研究结果不仅丰富了对中国金粟兰属植物的形态多样性、生活型、地理和生境分布特点等方面的认识,而且为正确划分和鉴别金粟兰属植物不同种类提供了更详实的依据,同时还为进一步深入研究该属植物物种的形成、演化和特殊分布格局的成因奠定基础,为这一类植物资源安全地可持续开发利用提供了保障。 |

| Abstract: |
| her connectives; and C. angustifolius is also distributed in Guizhou, beyond the documented known distribution areas of in Hubei and Chongqing. This study not only enriches and improves the understanding of morphological diversity, habit, geographical distribution of Chloranthus taxa in China, but also provides more detailed and robust evidence for correct identification and classification of different species in Chloranthus, serving as the foundation for future in-depth studies on speciation, evolution and underlying causes of the special distribution patterns in the genus, and ensuring the safe and sustainable development and utilization of these important plant resources. |
