ABSTRACT

 

As is reported to be a new species in China, the Rhynchotechum parviflorum Blume of the Rhynchotechum genus was found in Motuo County, Tibet. 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 (Tibet) of China. Therefore, the certificate of origin information recorded in the original document was questioned. At the same time, some stored specimens of Rhynchotechum in different herbaria were correctly identified as R. parviflorum (Anderson & Middleton, 2013). Thus, the China’s known distribution and detailed description of this species are presented here.
