云南东南部石山苣苔属一新种——细管石山苣苔（英文）
|
摘要
最近被重新界定的广义石山苣苔属(Petrocodon Hance)是苦苣苔科(Gesneriaceae)一个中等大小的属,我国目前已知的有34种1变种,主要分布于我国华南至西南石灰岩地区。该文报道了于云南东南部马关县发现的该属一新种——细管石山苣苔(Petrocodon tenuitubus W. H. Chen,F. Wen&Y. M. Shui)。该新种在形态上与陆氏细筒苣苔(P. lui)、细筒苣苔(P. hispidus)和长檐苣苔(P. jasminiflorus)相似,但其线形或披针形的苞片和小苞片均为3枚,花冠筒细小且弯曲,盘形柱头1,很容易区别于陆氏细筒苣苔和细筒苣苔;而其叶片卵形至圆形,花冠裂片卵形而尖端钝以及退化雄蕊3,则显著区别于长檐苣苔。该新种的发现对推进我国石灰岩地区苦苣苔科植物资源的发掘具有一定意义。主模式标本存放于中国科学院昆明植物研究所标本馆(KUN),等模式标本存放于广西植物研究所标本馆(IBK)。
The newly refined genus Petrocodon Hance( Gesneriaceae),mainly distributed from South China to Southwest China,is comprised of 34 species and one variety. A new species,Petrocodon tenuitubus W. H. Chen,F. Wen &Y. M. Shui,distributed in the limestone region from Maguan County,Yunnan Province,China,is illustrated and described here. The new species is similar to P. lui,P. hispidus and P. jasminiflorus,but it can be easily distinguished from P. lui and P. hispidus by its slender and curved corolla tube,three linear to lanceolate bracts and bracteoles,and one disc-shaped stigma. And it also can be easily distinguished from P. jasminiflorus by its ovate to orbicular leaves,ovate corolla lobes with obtuse apex,bracts and bracteoles 3,and staminodes 1. The discovery of this new species has certain significance for promoting the excavation of the resources of the Gesneriaceae in limestone area of China. The holotype and paratype specimens are deposited in Herbarium of Kunming Institute of Botany,Chinese Academy of Sciences( KUN); isotype specimens is deposited in Herbarium of Guangxi Institute of Botany( IBK).
