Primula pengzhouensis (Primulaceae), a new species from Sichuan, southwestern China

Abstract

A new species, Primula pengzhouensis (Primulaceae), from central Sichuan, China, is described and illustrated. It is assigned to Primula sect. Aleuritia subsect. Yunnanensis, and is most similar to P. socialis, but can be easily distinguished from that species by its much larger flower and elliptic or ovate-elliptic leaves.

Origins and evolution of plant diversity in the Hengduan Mountains, China

“… Xu et al. (2017) described and illustrated a new species, Primula pengzhouensis (Primulaceae), from the Hengduan Mountains (central Sichuan).…”

Primula sunhangii (Primulaceae): a new species from Hubei, Central China

“…Currently, many Primula species are poorly characterized, with a number of descriptions based on a single sample, which potentially results in undocumented details of characteristics such as pin or thrum morphology, fruiting, and ecology (Hu and Kelso 1996). Taxonomic study of Primula in China remains insufficient and requires continued efforts, as demonstrated by the large number of reports describing new species, including P. pengzhouensis C. M. Hu, G. Hao & Y. Xu. (Xu et al 2017), P. anthemifolia G. Hao, C. M. Hu & Yuan Xu (Xu et al 2015), and P. mianyangensis G. Hao & C. M. Hu (Wu et al 2013) collected from Sichuan; P. hubeiensis X. W. Li (Li et al 2017) collected from Hubei; and P. undulifolia G. Hao, C. M. Hu & Y. Xu (Xu et al 2016) collected from Hunan.…”

Primula dongchuanensis (Primulaceae), a new species from northern Yunnan, China

“…The modern center of diversity of Primula is in southwestern China, with ca 300 species of 24 sections, most of which occur in western Sichuan, eastern Xizang, and northwestern Yunnan (Hu 1994, Hu andKelso 1996). Increased exploration across this region results to the discovery and description of new Primula species in the past 15 years (Hu and Geng 2003, Wu et al 2013, Xu et al 2017a, 2017b, Yang et al 2017, Ju et al 2018 Section Proliferae Pax (10:217, 1889) of the genus Primula comprises more than 20 species, mainly distributed in Eastern Himalaya and Hengduan Mountain in China. Most species in this section are horticulturally important plants.…”
