| 摘要: |
| 乌恰县位于新疆维吾尔自治区西部,具有特殊的植物区系。作者基于对该地区的野外考察,通过标本研究和文献查证,报道了中国新疆西部的十字花科(Brassicaceae)一新记录属——双袋荠属(Didymophysa Boiss.)。双袋荠属目前共有3种,即新疆双袋荠(D. fedtschenkoana Regel)、双袋荠(D. aucheri Boiss.)、窗隔荠(D. fenestrata)。该文提供了该属的形态描述和分种区别特征,其中新疆双袋荠在我国首次记录,并提供了分布于我国新疆的新疆双袋荠的详细形态描述及生境照片。此外,该文还探讨了该新记录属种发现的生物地理学意义以及我国新疆西部高原地区的植物多样性和特殊性,同时提出了保护工作建议。 |

| Abstract: |
| Wuqia is located in the western part of Xinjiang, with a special flora. Based on field investigations of the region, through specimen research and literature review, Didymophysa Boiss., a newly recorded genus of Brassicaceae from western Xinjiang, China is reported. Didymophysa Boiss. have three species, D. fedtschenkoana Regel, D. aucheri Boiss. and D. fenestrata. The morphological description and the distinctive features to the species of Didymophysa are provided, and the detailed morphological description and photographs of D. fedtschenkoana Regel are provided. Lastly, the biogeographical significance of the discovery of newly recorded genus and species was discussed, as well as the plant diversity, specificity, and work recommendations in the western plateau region of Xinjiang. |
