| 摘要: |
| 糙毛苎麻(Boehmeria nivea var. strigosa Zeng Y. Wu & Y. Zhao)是一个苎麻新变种,原产于中国西南地区。该文主要基于形态学和分子系统学证据对其进行了描述。该变种的主要特征包括叶片背面绿色、托叶部分合生以及茎和叶柄上浓密的糙毛。基于rbcL、nrDNA和rbcL+nrDNA 3个数据集构建的系统发育关系结果均表明strigosa糙毛苎麻的所有个体形成一个单系分支。根据IUCN的评估标准,糙毛苎麻被评估为“近危”( NT)。该新变种的发现对苎麻的分类至关重要,并且为苎麻资源的开发和利用提供了科学依据。 |

| Abstract: |
| Boehmeria nivea var. strigosa Zeng Y. Wu & Y. Zhao, a new variety of B. nivea(Urticaceae)from Southwest China, is here described based on evidence from morphology and molecular phylogeny. This new variety is mainly characterized by its green abaxial leaf blade, partly connate stipules, and densely patent strigose hairs on stems and potioles. The phylogenetic analysis based on rbcL, nrDNA and rbcL+nrDNA datasets, revealed that all individuals of B. nivea var. strigosa formed a monophyletic group. The conservation status of B. nivea var. strigosa is assessed as “Near Threatened”(NT)according to IUCN evaluation criteria. The discovery of this new variety is not only crucial for the taxonomy of ramie, but also provides reference for the exploration and utilization of ramie. |
