A phylogenetic analysis of the Old World genus Doronicum (26 species, 4 subspecies) based on sequence data of the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA, the chloroplast spacer trnL-F, and morphology is presented. Congruence among the three data sets was explored by the computing of several indices, all of which suggest homogeneity between only the two molecular matrices. We argue that the morphological data set contains poor phylogenetic signal and advocate simultaneous analysis of the three data sets (total evidence approach) so that morphological characters are tested for homology by congruence with molecular data. The resulting phylogenetic hypothesis allows several well-supported conclusions including the placement of a Corsican endemic (D. corsicum), sister to the remainder of the genus, and the inference that an early southern European or Mediterranean diversification took place in the genus. Shifts in morphological characters (e.g., homocarpy to heterocarpy) are confirmed to have evolved several times. Results from comparative studies of sequence data of the chloroplast gene ndhF support inclusion of Doronicum in tribe Senecioneae.

“…1c) between 1500 and 1800 m a. s. l. (Álvarez Fernández 2003;Essl 2009). Doronicum cataractarum was discovered in 1853, but initially erroneously considered to belong to D. pardalianches L. Only about 70 years later, it was recognized and described as a new species (Widder 1925). For the placement of D. cataractarum within the genus, Widder (1925) followed the classification of Doronicum L. by Cavillier (1907Cavillier ( , 1911, the then latest monograph of the genus.…”

“…Based on the tall growth, the multiheaded synflorescences, the relatively long internodes, the high number of basal leaves, the shallowly cordate leaf bases ( Fig. 1d) and the lack of a pappus on the ray florets, Widder (1925) Boiss. & Heldr.…”

“…These alternative classifications of D. cataractarum imply two hypotheses concerning the species' origin. According to Widder (1925), D. cataractarum represents the westernmost member of subsect. Macrophylla (hereinafter referred to as Macrophylla group), whose remaining species are found from the Caucasus and the Armenian highland west to Asia Minor (Fig.…”

“…1a). Widder (1925) interpreted the highly disjoint distribution of the Macrophylla group as the result of vicariant speciation into higher elevations from a Tertiary ancestor of subtropical woodlands. Based on the perceived systematic isolation within the Macrophylla group, the restriction to very specific habitats, the lack of morphological variation and the highly fragmented occurrence on Mount Koralpe, Widder (1925) argued that D. cataractarum "with certainty is a representative of the Tertiary ancestral flora" (translated from German).…”

Phylogeny and biogeography of the narrowly endemic Doronicum cataractarum (Asteraceae) from the eastern European Alps: Pleistocene origin from Alpine ancestors rather than Tertiary relic with southwest Asian affinity

et al. 2018

Distribution areas of narrowly endemic species in the European Alps often coincide with Pleistocene refugia, suggesting that allopatric divergence due to Pleistocene range shifts might have been instrumental in their origin. Here, we infer the phylogenetic position of the locally endemic Doronicum cataractarum testing previous hypotheses with respect to its biogeographic and temporal origin (Tertiary origin with southwest Asian affinities versus possibly Pleistocene origin in the Alps). To this end, we extended existing genus-wide data sets of nuclear and plastid DNA sequences and obtained sequences from two hitherto not used low copy nuclear markers. These data sets were analyzed, as single markers and jointly in a concatenated matrix, using maximum parsimony and maximum likelihood. Temporal and spatial origins of D. cataractarum were inferred using mean path lengths and dispersal-vicariance analysis, respectively. Phylogenetic resolution was limited, but several geographically coherent groups were identified, including the Grandiflora group comprising southern and central European mountain species. Congruently, D. cataractarum was inferred as most closely related to Alpine species from the Grandiflora group (D. clusii, D. stiriacum and D. glaciale), but neither to southwest Asian species nor to European D. austriacum. The origin of D. cataractarum was conservatively dated to about 1.9 Mya and inferred to have taken place in the Alps. The striking morphological differences between D. cataractarum and the most closely related species likely are the result of adaptation to different habitats or, alternatively, the presence of plesiomorphic traits in D. cataractarum.
