  abstract  = {Hieracium rotundatum subsp. silvae-bavaricae is described as new for science and illustrated. The new subspecies belongs to a group of species (H. rotundatum, H. transylvanicum) whose main distribution is in the Balkans. The changeful nomenclatural history of the species name is described. Diagnostic features to distinguish the growth habit-similar species H. murorum, H. rotundatum and H. transylvanicum are discussed. Particular attention is drawn to the importance of the development of the basic leaf cycle. Contrary to previous knowledge, the northwestern distribution limit of H.rotundatum extends now to southeastern Bavaria. During the search for H. rotundatum a morphologically conspicuous subspecies of H. rotundatum could be detected, which is described here as new.},

  abstract  = {In Lower Franconia/Northern Bavaria, a well-defined subspecies of the Hieracium maculatum group was detected. This subspecies is restricted to the slopes of the Main valley between W{\"u}rzburg and Hasloch with a hot spot (>90\% of total population) between the villages Th{\"u}ngersheim and Retzbach. Due to some similarities with H. glaucinum subsp. prasiophaeum (synonym: subsp. gougetianum) the subspecies is named H. maculatum subsp. pseudogougetianum. This subspecies grows preferentially on shell-bearing limestone gravels and begins flowering as early as mid-April. Head involucra are whitish hairy mixed with dark stalked glands. The basal leaf rosette consists of ovate to elliptic, toothed to serrate, dark spotted leaves, glabrous, glaucous above. Stems bear 1-3(4) stalked stem leaves and usually form long lateral flowering branches from the leaf axils. Like some other H. maculatum subspecies, H. maculatum subsp. pseudogougetianum is tetraploid with a mean genome weight (2C value) of 14.5 pg, distinguishing it from the H. glaucinum group, whose studied taxa are invariably triploid (mean 10.1 pg).},
