Summary Karis, P. O., Eldenäs, P. & Källersjö, M.: New evidence for the systematic position of Gundelia L. with notes on delimitation of Arctoteae ( Asteraceae ). – Taxon 50: 105–114. 2001. – ISSN 0040‐0262. The systematic position of the thistle‐like Gundelia of Asteraceae‐Arctoteae is investigated by using sequences from the chloroplast gene ndhF in a parsimony jackknife analysis. Unexpectedly, the analysis indicates strong support for placing Gundelia with tribe Lactuceae, rather than with tribe Arctoteae. Gundelia's morphology is discussed in light of this new grouping. Another clade, although weakly supported, is formed by representatives of Arctoteae, including the two South African genera Eremothamnus and Hoplophyllum. The latter two form a sister group with 100 % support.
