Abstract
The systematic position of the thistle-like Gundelia of Asteraceae-Arctotea e is investigated by using sequences from the chloroplast gene ndhF in a pa rsimony jackknife analysis. Unexpectedly, the analysis indicates strong sup port for placing Gundelia with tribe Lactuceae, rather than with tribe Arct oteae. Gundelia's morphology is discussed in light of this new grouping. An other clade, although weakly supported, is formed by representatives of Arc toteae, including the two South African genera Eremothamnus and Hoplophyllu m. The latter two form a sister group with 100 % support.
