Lysimachia septemfida (Primulaceae), a new species from Yunnan, China

Abstract

A new species, Lysimachia septemfida (Primulaceae), from Yunnan (Southwest China) is described and illustrated. The new species exhibits several unusual characters in Lysimachia including lack of a corolla, 7-merous flowers, leaves in whorls of 3 and distinct multicellular nodiferous hairs, which make it readily distinguishable from all other species in this genus. The diagnostic differences between this new species and its suppositive allies are given. In addition, the systematic placement of this new species is also discussed based on an ITS molecular tree.

Reactions of Pollen of Plants from Genus Lysimachia L. on Diferrent Enviromental Conditions

“…Рід Lysimachia містить приблизно 140-200 видів з поширенням по всьому світу і за результатами сучасних досліджень досить активно доповнюється новими видами (Loc and Hu, 2011;Zhang et al, 2012;Zhou et al, 2015;Wang et al, 2016). В Україні наведені 5 видів цього роду (Lysimachia nummularia L. (вербозілля лучне або монетне), L. vulgaris L. (в. звичайне), L. nemorum L. (в. гайове), L. punctata L. (в. крапчасте), L. verticillaris L. (в. кільчасте) (Didukh et al, 2010).…”

Lysimachia coriacea (Primulaceae, Myrsinoideae), a new species from Chongqing, China

“…China has been considered as the diversity centre of this genus with approximately 130 species recorded in Flora of China (Hu and Kelso 1996). Subsequently, at least 20 new species have been discovered in the last two decades (Peng and Hu 1999;Shao et al 2004;Shao et al 2006;Yan and Hao 2012;Liu et al 2014a, b;Estes et al 2015;Zhou et al 2015;Baskose et al 2016;Julius et al 2016;Wang et al 2016;Yan et al 2017;Wang et al 2018;Huang et al 2019;Liu et al 2020;Mou et al 2020;Yi 2020;Ju et al 2021;Lu et al 2021). In recent years, multiple field expeditions have been conducted in the Municipality of Chongqing, China.…”
