| Summary: | com esen elon ont from about 100, predominantly European taxa of subg. Esula in order to infer its phylogenetic history. h over s of flo). Dist als to 2 and Křísa, 1992). The subgenus Esula includes roughly 500 herba-ceous perennials, annuals, shrubs, small trees and succulents nat-urally occurring on all continents except Australia and Antarctica, but achieving its greatest diversity in northern temperate regions (Bruyns et al., 2006; Steinmann and Porter, 2002). Most species have alternate, exstipulate and (sub)sessile cauline leaves and ter-minal pleiochasial inflorescences. The stem growth terminates They have shown that although Euphorbia subg. Esula as tradition-ally circumscribed (e.g., Wheeler, 1943) is polyphyletic, most taxa form a clade (referred to as ‘‘clade B’ ’ by Steinmann and Porter, 2002), including also some African succulent species from subge-nus Tirucalli (Boiss.) S. Carter. This clade has relatively high support (86 % bootstrap) in the ndhF tree, but no support in the ITS tree. Later, Bruyns et al. (2006) inferred the phylogeny of southern African spurges using ITS and plastid psbA-trnH sequences. With partly different taxon sampling they corroborated the main results of Steinmann and Porter (2002). Similar results were obtained by |
