本研究团队近年在新疆杂草野外实地考察过程中,在博州和哈密地区发现3种新疆未曾记录的植物,通过形态分类学鉴定和文献查证,确定为茄科(Solanaceae)和旋花科(Convolvulaceae)外来新分布种,分别是灰绿酸浆(Physalis grisea(Waterf.)M.Martínez)、小酸浆(Physalis minima L.)和瘤梗番薯(Ipomoea lacunosa L.).3 种均为新疆新记录植物和外来杂草.灰绿酸浆在博州地区有较大范围居群;小酸浆、瘤梗番薯在哈密地区有小范围居群.本文补充并完善了 3种新记录植物的形态描述和地理分布范围,以检索表形式将其与新疆原有近缘种进行了对比分析.3种新记录植物的发现,为新疆植物区系与物种多样性研究提供了新资料,也为新疆外来杂草的监测与防控提供了理论依据.凭证标本保存于石河子大学植物标本馆(SHI).
New records of three exotic plants of the Solanaceae and Convolvulaceae in Xinjiang
During fieldwork on weeds in the Xinjiang wilderness in recent years,our research team found three herbaceous species in Bozhou and Hami that had not been previously recorded in Xinjiang.Through morphological taxonomic analysis and a review of litera-ture,the collected specimens were identified as exotic and new distributional species of the Solanaceae and Convolvulaceae families,namely Physalis grisea(Waterf.)M.Martínez,Physalis minima L.,and lpomoea lacunosa L.All three species are newly recorded exotic weeds in Xinjiang.We report a large population of Physalis grisea(Waterf.)M.Martínez in the Bozhou area and smaller popu-lations of Physalis minima L.and Ipomoea lacunosa L.in the Hami area.Supplementary morphological descriptions and geographic ranges of the newly recorded plants were documented,and a comparison of the specimens with their original relatives in Xinjiang was carried out in the form of a search table.The discovery of these three species in Xinjiang provides new information on the flora and spe-cies diversity of the region and also provides a theoretical basis for the monitoring,prevention,and control of exotic weeds in Xinjiang.Further investigation is required to gauge the possible impacts of these exotic species on the native plant communities and ecology of wild areas of Xinjiang.The voucher specimen are preserved in the Herbarium of Shihezi University(SHI).
