| 摘 要： | 在野外调查的基础上，结合查阅标本和文献比对，对秦岭地区芍药属(Paeonia)植物及其地理分布进行修订。结果表明，秦岭地区分布有芍药属8个野生种及1个栽培种，可分为牡丹组(Section Mouton DC.)和芍药组(Sect. Paeonia)。地理分布格局研究表明：芍药组内4个种：草芍药(P. obovata)、美丽芍药(P. mairei)、芍药(P. lactiflora)、川赤芍(P. anomala subsp. veitchii)和牡丹组中的牡丹(P. suffruticosa Andrews)、紫斑牡丹(P. rockii)为秦岭广布种，卵叶牡丹(P. qiui)和杨山牡丹(P. ostii)为秦岭中东部分布种，矮牡丹(P.jishanensis)为秦岭东部分布种。根据修订，给出了秦岭地区芍药属植物分种检索表。

| Abstract: | It was undertaken on the revision of Paeonia species in Qinling Mountains by the field investigation, herbarium specimens and literature record. The results showed that there were eight wild species and one cultivar in this region, and they were classified into two groups: sect. Mouton and sect. Paeonia. Geographic distribution study showed that four species belonging to sect. Paeonia: P. obovata, P. mairei, P. lactiflora, P. anomala subsp. veitchii, also P. suffruticosa Andrews and P. rockii were widespread, P. qiui and P. ostii were found in middle and eastern regions, and P. jishanensis was only in eastern region of Qinling Mountains. Finally, a key to species was proposed. |
