Phylogeny and evolution of the Arctium-Cousinia complex (Compositae, Cardueae-Carduinae)
The phylogeny and evolution of the Arctium-Cousinia complex, including Arctium, Cousinia as one of the largest genera of Asteraceae, Hypacanthium and Schmalhausenia, is investigated. This group of genera has its highest diversity in the Irano-Turanian region and the mountains of Central Asia. We generated ITS and rpS4-trnT-trnL sequences for altogether 138 species, including 129 (of ca. 600) species of Cousinia. As found in previous analyses, Cousinia is not monophyletic. Instead, Cousinia subgg. Cynaroides and Hypacanthodes with together ca. 30 species are more closely related to Arctium, Hypacanthium and Schmalhausenia (Arctioid clade) than to subg. Cousinia (Cousinioid clade). The Arctio…
Sesquiterpene lactones, lignans and aromatic esters from Cheirolophus species
Abstract The aerial parts of five Cheirolophus species yielded three new guaianolides, a new lignan and three new aromatic esters, together with other known compounds of the same type.
Which changes are needed to render all genera of the German lora monophyletic?
