FIGURE 4 in Integrative approach resolves the taxonomy of the Ozothamnus ledifolius (Asteraceae: Gnaphaliae) species complex in Tasmania, Australia

FIGURE 4. Non-hierarchical clustering analysis of 80 samples of Tasmanian Ozothamnus, using K=6 and a priori identifications. Grey shading is used to indicates discrete analysis clusters. Group 1 corresponds with south-eastern lowland populations of O. 'purpurascens' (sensu auct. non DC.); Group 2 with north-eastern highland populations of O. "St Pauls Dome"; Group 3 is comprised of O. ericifolius and O. "Merchants Hill" (note separate subclusters EO and OF, denoting O. ericifolius and O. "Merchants Hill", respectively); Group 4 was a single, juvenile outlier of O. "Merchants Hill"; Group 5 corresponds with O. ledifolius, and Group 6 with the Poatina cluster of identified a priori as O. aff. ledifolius and O. aff. purpurascens. (A) View of axes 1 and 2.
