| 摘 要： | 该文报道了产自中国西藏自治区墨脱县境内的线柱苣苔属(Rhynchotechum Blume)中国分布新记录——小花线柱苣苔(R. parviflorum Blume)。该新记录种常生长在林中溪流附近的崖壁以及次生林下阴湿生境中,主要辨别特征为叶基本对生,花萼裂片被绢毛,花梗被黄褐色绒毛,花冠筒较小,子房具短柔毛,果无毛至微柔毛。印度学者于2020年记载为印度新分布,而原始文献中记录的凭证标本采集点位于中国西藏自治区墨脱县境内,故对原文记述的产地信息提出质疑。同时,在前人的研究中部分馆藏的线柱苣苔属植物标本被认定为该新记录种,在此一并提出该新记录种在中国的分布地理信息和详细描述。

| Abstract: | As is reported to be a new species in China, the Rhynchotechum parviflorum Blume of the Rhynchotechum Blume genus was found in Motuo County, Xizang Autonomous Region of China. It usually prefers cliffs near perennial streams in primary forests as well as in secondary forests and damp groves near roadsides. This species of Rhynchotechum is characterized by almost opposite leaves, sericeous calyx lobes, axes rusty-yellow villous, short style and small flower, puberulent ovary and glabrous to puberulous fruit. When the research about this genus was published in 2020, Indian scholars recorded that the voucher specimen was collected from India. However, when the GPS longitude and latitude information of the type specimen collection point recorded in the original document was marked on the Map World in official geographic website, this species was found to locate in Motuo County, Xizang Autonomous Region of China. Therefore, the certificate of origin information recorded in the original document was questioned. |
