Abstract
A new subtribal classification of the Compositae-Anthemideae is presented based on phylogenetic reconstructions for sequence information of the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA (nrDNA) for 103 of the 111 accepted genera of the tribe. Results of the present analyses are compared with results from phylogenetic analyses based on cpDNA ndhF sequence variation and discussed in conjunction with morphological, anatomical, cytological, embryological and phytochemical evidence. As a result, 14 subtribes are circumscribed and described in detail, with information provided concerning the generic members and the geographical distribution of these entities. Four subtribes (i.e. Osmitopsidinae, Phymasperminae, Pentziinae and Leucanthemopsidinae) are described as new to science, for a further subtribe a new name (Glebionidinae, replacing the illegitimate Chrysantheminae) is validated.
