摘要:
该文报道了国产杜鹃花科(Ericaceae)一新记录种,即埃氏越橘(Vaccinium eberhardtii Dop).该种隶属于越橘属(Vaccinium)南烛组(Vaccinium sect.Bracteata),与同属于该组的南烛(V.bracteatum)和海岛越橘(V.wrightii)近缘,但与前者的区别在于花序梗、花梗、萼筒无毛,花冠球状坛形,药室背部明显具2个距,与后者的区别在于花梗较短,短于苞片,药室背后的距直立,长超过药管的一半.据文献记录,该种原来仅分布于越南中部和泰国,此次发现该种的分布范围可以北延至中国的广西东兴市的沿海地区,不仅丰富了越橘属分类、分布的数据,也为今后该属的分类学修订提供了新资料.凭证标本保存在中国科学院华南植物园标本馆(IBSC)和中国科学院广西植物研究所标本馆(IBK)中.%Vaccinium eberhardtii Dop (Ericaceae), a species previously known only from Vietnam and Thailand, is newly recorded from China. This species belongs to Vaccinium sect. Bracteata, and it is similar to the other two members of the same section, i.e. V. bracteatum and V. wrightii. However, V. eberhardtii is different from the former in having glabrous peduncle, pedicel and calyx tube, glabrous spherical-urceolate corolla and anthers with two conspicuous spurs, and can be easily distinguished from the latter by having pedicels, shorter than bracts and the upward spurs on the back of the anther, and longer than half of the anther tube. Previously, it was reported only from Central Vietnam and Thailand. This new finding extends its distribution to the coastal areas of Dongxing City, Guangxi Zhuang Autonomous Region, South China, which adds new distribution information for this species and the future taxonomic revision of the whole genus. The vouchers are kept in the herbaria of South China Botanical Garden, Chinese Academy of Sciences (IBSC) and Guangxi Institute of Botany, Chinese Academy of Sciences (IBK).
