摘　　要：文章报道了在青海省西宁市发现的茄科(Solanaceae)假酸浆属(Nicandra)植物——假酸浆(Nicandra physalodes),该植物代表了青海省一个新归化属。本研究对其形态特征、标本采集地环境进行了描述;基于rbcL序列对青海省的茄科植物进行系统发育分析,显示假酸浆与茄属、辣椒属和曼陀罗属有较近的亲缘关系。假酸浆在青海的发现更新了假酸浆属在我国的分布格局,丰富了青海省茄科植物的种类,但其对青海本土植物以及生态环境的影响仍需进一步研究和讨论。Nicandra physalodes, a plant of the genus Nicandra in the Solanaceae family, found in Xining,Qinghai Province, China, was reported. This plant represents a new naturalized genus in Qinghai Province.In this study, its morphological characters and the environment of the specimen collection site were described. Phylogenetic analysis of the Solanaceae from Qinghai Province based on rbcL sequences showed that N. physalodes is closely related to the genera Solanaceae, Capsicum and Mandarins. The discovery of N. physalodes in Qinghai has updated the distribution pattern of the genus N. physalodes in China and enriched the species of Solanaceae in Qinghai Province, but its impact on the native plants and ecological environment of Qinghai still needs further study and discussion.
