A new species of Kali (Salsoloideae, Chenopodiaceae) from Sicily, supported by molecular analysis

Abstract

Nomenclatural and taxonomical considerations on Kali, a controversial genus recently segregated from the polyphyletic Salsola s. lat. (Chenopodiaceae), are provided. The Kali group includes annual plants with leaves ending in a spine and lacking hypodermis, having also a cortex alternate to longitudinal chlorenchymatous striae. The species belonging to this genus mainly have a paleotemperate distribution (Europe, Asia and North Africa), occurring as aliens in North America, Australia and South Africa. A new species collected on Mt. Etna (Sicily), and closely related to K. australe, is described and illustrated as K. basalticum Its morphological and molecular features, karyology (2n=54), ecology, distribution, phylogeny and conservation status are examined. In addition, a list of the currently known species of Kali is provided, with some new combinations: Kali nepalense (Grubov) comb. nov., Kali pellucidum (Litvinov) comb. nov., Kali sinkiangense (A.J. Li) comb. nov., Kali gobicolum (Iljin) comb. nov., and Kali ryanii (G.F. Hrusa & Gaskin) comb. nov.

The first record of Salsola paulsenii (Chenopodiaceae) in Ukraine, with taxonomic and nomenclatural comments on related taxa

“…A rather representative sampling of S. tragus from that habitat (about 25 morphologically diverse plants, KW) was done on 22 September 2017 during my second visit to the Obolon locality. At least two sampled plants of * Based on Iljin (1936); Rilke (1999); Hrusa, Gaskin (2008); Brullo et al (2015a), etc., and original observations. For additional diagnostic characters, see the references cited in the text.…”

“…Salsola paulsenii is a tetraploid species with 2n = 36 (Zakharyeva 1985;Rilke 1999;Lomonosova et al, 2003;Brullo et al, 2015a). Both tetraploid and diploid (sometimes) chromosome counts were reported for S. tragus, but the weedy races most widespread in Eurasia and North America seem to be mainly or exclusively tetraploids (Rilke, 1999;Hrusa, Gaskin, 2008;Brullo et al, 2015a, etc.).…”

Taxonomic and nomenclatural notes on Pontic-Mediterranean coastal and some Australasian taxa of Salsola (Chenopodiaceae)

“…This species was firmly forgotten even by Italian authors (probably because its name was considered invalid), and only occasionally S. controversa was mentioned in literature, mainly as a synonym of S. kali or S. tragus (see, e.g., Casu, 1910). It has not been mentioned at all in recent Italian publication on Salsola sensu lato (Brullo et al, 2013(Brullo et al, , 2015a and in the inventory of plant species described from Italy and their loci classici (Peruzzi et al, 2015).…”
