【摘要】 牡丹是芍药科(Paeoniaceae)芍药属(Paeonia)牡丹组(Sectiion Mouton DC.)的多年生落叶灌木,原产中国,组内包括9个野生种及1个栽培种。结合查阅标本和文献比对,在野外调查的基础上,对中国分布的牡丹组植物地理分布进行重新修订。结果表明,牡丹组9个野生种分布于中国8省份(自治区),其中陕西省资源最为丰富,包括4个种1个亚种,而山西省仅有矮牡丹(P.jiishanensis)分布。紫斑牡丹(P.rockii)分布于陕西、甘肃、河南及湖北,是分布范围最广的野生种,而狭叶牡丹(P.potaninii)仅分布于四川雅江。革质花盘亚组(Subsect.Vagtnatae F.C.Stern)主要分布于子午岭、秦巴山区及青藏高原东部地区海拔700~3000m的山坡灌丛及林下,肉质花盘亚组(Subsect.Delayanae F.C.Stern)主要分布于云贵高原西北部及青藏高原东南部海拔2000~3600m的山地灌丛中,二者在水平和垂直分布上均有较为明显的区别。更多还原

【Abstract】 Tree peony,belonging to section Moutan DC.of the genus Paeonia L.(Paeoniaceae),is a perennial woody shrub native to China,including nine wild species and one cultivar.It was undertaken on the revision of geographical distribution of section Moutan species in China by the field investigation,herbarium specimens and literature record.The results showed that nine species belonged to Section Mouton DC.distributed in eight provinces in China,and there were four species and one subspecies in Shaanxi Province,while Shanxi Province only had P.jishanensis.P.rockii,found in Shaanxi,Gansu,Henan and Hubei Province,was the most widely distributed species,while P.potaninii was only found in Yajiang,Sichuan.Subsection Vaginatae F.C.Stem was mainly distributed in the thickets and forest from 700 to 3000 m in Ziwuling,Qinling-Daba Mountains and Eastern Tibetan Plateau,and Subsection Delavayanae F.C.Stern was mainly found in the limestone and thickets from 2000 m to 3600 m in Northern Yunnan-Guizhou Plateau and Southern and Eastern Tibetan Plateau.From horizontal and vertical perspectives,the natural distribution areas of two subsections were different更多还原
