Primula pingbaensis (Primulaceae), a new species from Guizhou, China

Abstract

Primula pingbaensis Na Zhang, X.Q.Jiang & Z.K.Wu, a new species of Primulaceae from Gaofeng Mountain of Pingba county, Guizhou, China, is described and illustrated. Morphological evidence supports P. pingbaensis as a member of P. sect. Petiolares on account of scape elongating, pedicels conspicuously thickening in fruit, and its capsule cracking irregularly round the top and crumbling away. Amongst the members of subsect. Davidii, the new species is characterized by having a uniquely smooth leaf blade due to inconspicuously raised veinlets and homostylous flowers with the style usually extending beyond the anthers. The distribution, phenology and conservation status of the new species are also provided.

“…The Primula sect. Petiolares Pax is one of the largest sections in Primula ; more than 60 species of this section are now recognized worldwide ( Hu 1994 ; Hu and Kelso 1996 ; Richards 2002 ; Hu and Geng 2003 ; Li and Hu 2009 ; Rankin 2010 ; Hu and Hao 2011 ; Xu et al 2014 , 2016 , 2022 ; Ju et al 2018 ; Yuan et al 2018 ; Wei et al 2022 ; Xu et al 2022 ; Zhang et al 2023 ), and are well represented in the Himalaya–Hengduan mountains, with only a few members extending into Kashmir, central China, and some other regions ( Hu 1990 ; Hu and Kelso 1996 ). This section was further divided into seven subsections based on the presence or absence of the basal bud scales and farina, the shape of the leaf margin, and the type of hair ( Smith and Fletcher 1944 ).…”

“…The genus Primula L. is one of the largest genera in the Primulaceae , encompassing approximately 536 species ( Ju et al 2023 ; Li et al 2023 ; POWO 2023 ; Wang et al 2023 ; Wu et al 2023a , b ; Yang et al 2023 ; Zhang et al 2023 ). In China, the last comprehensive account of the genus was that of Hu and Kelso (1996) who treated 300 species in the “Flora of China”.…”
