A new species of Chrysosplenium (Saxifragaceae) from Northeastern China

Abstract

This study describes and illustrates Chrysosplenium macrospermum Y.I.Kim & Y.D.Kim, a new plant species from Changbaishan Mt. (Baekdusan Mt.) in northeastern China. The species is most similar to Chrysosplenium valdepilosum in the series Pilosa but is readily distinguishable by short arching sterile branches, multiple (up to 3) flowering stems, and smooth surfaced seeds (without tubercles), which are ca. 30–50% larger than those of other members in the series.

Chrysosplenium sangzhiense (Saxifragaceae), a new species from Hunan, China

“…During the trip an unknown species of Chrysosplenium was collected. Following a thorough literature survey (Hara 1957;Pan 1992;Pan and Ohba 2001;Liu et al 2016;Kim et al 2019;Fu et al 2020) along with the molecular and cytological evidence, we confirmed that it is a distinct and undescribed species.…”

“…Chrysosplenium L. (1753) is a perennial herbaceous genus in Saxifragaceae and comprises more than 70 species (Kim et al 2019;Fu et al 2020). Chrysosplenium is distributed in Asia, America and Europe (Pan and Ohba 2001;Soltis 2007).…”

“…Soltis et al (2001) showed that the two subgenera are both monophyletic and sister to each other using matK sequence data, thereby confirming that leaf arrangement is a phylogenetically informative morphological character. Subsequent taxonomic research on Chinese Chrysosplenium has been undertaken by Liu et al (2016), Kim et al (2019) and Fu et al (2020), bringing the total diversity of the Chinese flora to 38 species, of which 23 (60%) are endemic.…”

A new species of Chrysosplenium (Saxifragaceae) from Shaanxi, north-western China

“…Chrysosplenium L. (Saxifragaceae) is a small perennial herbaceous genus that comprises ca. 70 species (Kim et al 2019). Chrysosplenium is distributed throughout the temperate regions of the Northern Hemisphere, with high species diversity in eastern Asia, America and Europe (Hara 1957;Pan 1986aPan , b, 1992Pan and Ohba 2001;Soltis 2007).…”

“…China is one of the diversification centres of this genus including ca. 37 species, the majority of which are distributed in south-western, northern and central China, particularly the Provinces of Yunnan, Xizang, Sichuan and Shaanxi (Pan and Ohba 2001;Liu et al 2016;Kim et al 2019).…”
