Oreocharis tetrapterus (Gesneriaceae), a new species from East Guangxi, China

Abstract

A new species, Oreocharis tetrapterus F.Wen, B.Pan & T.V.Do (Gesneriaceae) from Gupo Mountain area, Hezhou city, Guangxi Zhuangzu Autonomous Region, China, is described and illustrated. The new species has a zygomorphic tetramerous corolla with two adaxial and two abaxial lobes and two fertile stamens in the posterior position, making this a unique combination of floral characteristics in the expanded Oreocharis.

“…The gender of the genus name, Oreocharis, is feminine, but the suffix of the scientific name, "-us," is typically masculine. For Oreocharis tetrapterus (Pan et al 2019), the correct orthography of the name of the new species is O. tetraptera, is written by using an inaccurate gender, namely "tetrapterus", in the citation of the type of the new species (p. 85), in the discussion of the Etymology (p. 86) and in the notes of the illustration (pp. 86, 87 and 88).…”

“…At least 30 new taxa of Oreocharis Benth. (Gesneriaceae) have been described and officially published (e.g., Cai et al 2017Cai et al , 2019Do et al 2017;Chen et al 2018;Guo et al 2018;Möller et al 2018;Pan et al 2019;Yang et al 2019) after the generic redefinition based on new evidence following the development of molecular phylogenetics in 2011 (Möller et al 2011) and several later adjustments of the species (Middleton et al 2013;Chen et al 2014;Möller et al 2014;Möller 2015). Oreocharis s.l.…”

“…hitherto comprises more than 140 taxa, mainly distributed in South and Southwest China (Wen et al 2014(Wen et al , 2019 and a few species extending into North Vietnam (nine species), Myanmar (two species), Bhutan (one species), India (one species), Japan (one species) and Thailand (one species) (Xuyen et al 2016;Do et al 2017;Möller et al 2017Möller et al , 2018Chen et al 2018). Li and Li (2015) and Pan et al (2019) each described new species of Oreocharis. One of the taxa with four corolla lobes is from Guangxi, China, which they named O. tetrapterus F.Wen, B.Pan & T.V.Do (Pan et al 2019).…”

“…Li and Li (2015) and Pan et al (2019) each described new species of Oreocharis. One of the taxa with four corolla lobes is from Guangxi, China, which they named O. tetrapterus F.Wen, B.Pan & T.V.Do (Pan et al 2019). The other has sessile or shorter petiole leaves and four stamens with anthers coherent in pairs from Guizhou, China, which was named as O. brachypodus J.M.…”

“…After Oreocharis Bentham (Bentham ) was redefined (Möller et al ) and adjusted based on molecular and morphological data (Middleton et al , Chen et al , Möller et al ), the genus has rapidly grown by the addition of many new species. There are at least 30 new taxa described and published after the redefinition (Tan et al , Möller et al , Wei et al , Cai et al , , Yang et al , Möller , Pan et al , Wen et al ). Oreocharis now comprises more than 120 species and most of them are endemic to China, mainly distributed in south and southwest China, with other species occurring in North Vietnam, Myanmar, northeast India, Bhutan, Japan and Thailand (Wang et al , , Li and Wang , Möller et al , , Xu et al , Chen et al ).…”
