摘要：

The sequences of the internal transcribed spacer (ITS) region of 18S-26S nrDNA for a sample of 16 taxa from the Inuleae s. str. and two outgroup taxa are analysed cladistically with PAUP. A consensus tree of the four most parsimonious cladograms is presented. Three different tests of cladogram stability are conducted (Bremer support, parsimony jackknifing and bootstrapping); all tests indicate a high degree of support for the basal nodes of the tree. The ITS phylogeny of the tribe is compared with previous hypotheses based on morphological data. The position of Anisopappus as sister group to the rest of the tribe is supported by the molecular data, but the proposed subdivision of Inuleae s, str. into a paleate grade group and an epaleate clade is not. The interpretation of the character evolution of, e.g. receptacular paleae and pappus features within the tribe is discussed.
