Abstract

A first comprehensive phylogenetic analysis of tribe Salsoleae s.l. (Salsoloideae: Chenopodiaceae) is presented based on maximum parsimony and maximum likelihood analysis of nuclear ribosomal ITS and chloroplast psbB-psbH DNA sequences. Our data strongly support 1) the sister relationship of Camphorosmeae to the Salsoleae s.l., 2) splitting of Salsololeae s.l. into two monophyletic tribes, Salsoleae s.s. and Caroxyloneae tribus nova, 3) the current status of most monotypic or oligotypic genera in Salsoleae, 4) polyphyly of the Botschantzev and Freitag?s (among others) circumscriptions of Salsola, which falls into ten (on average) monophyletic genera/lineages. Three well-supported genera are described as new, including Pyankovia, Kaviria, and Turania, and four previously described genera are resurrected, including Caroxylon, Climacoptera, Kali, and Xylosalsola. Salsola s.s. include a group of central and southwest Asian and north African species which assemble Salsola section Salsola s.s., S. section Caroxylon subsection Coccosalsola, Salsola section Obpyrifolia, Fadenia, Hypocylix, Seidlitzia, and Darniella. All species of tribe Caroxyloneae investigated so far have C4 photosynthesis of the NAD-malic enzyme subtype while the majority of the species of Salsoleae s.s. are known to be NADP-malic enzyme subtype.
