Rediscovery and conformation of Oreocharis rhytidophylla (Gesneriaceae) with supplementary description of flowers

GuihaiaDOI: 10.11931/guihaia.gxzw201808032

ABSTRACT

    The flower morphological is a key trait for sub-division and inter-species definition of the Oreocharis. Oreocharis rhytidophylla C. Y. Wu ex H. W. Li was last collected in 1956 and published in 1983, the species has no relevant collection records for the next 60 years. Due to the lack of flower morphological, there are doubts in “Flora of reipublicae popularis sinicae”, “Plants of Gesneriaceae in China” and “flora of China”. After years of follow-up investigation, Oreocharis rhytidophylla C. Y. Wu ex H. W. Li was rediscovered in 2017 in it type locality. Due to the availability of the flowers during the rediscovery, we confirmed that the species should be considered as a natural species instead of doubtful one. The floral morphology of Oreocharis rhytidophylla C. Y. Wu ex H. W. Li was supplemented based on the recent collections and photos. Its rediscovery provided an opportunity to explore its systematic position in the context of phylogeny in the future.
