Durch Farbmarkierungen wird gekennzeichnet, welche Unterart urspr{\"u}nglich aus einem Bundesland beschrieben wurde bzw. ob ein Syntypus aus einem Bundesland stammt.},

  abstract  = {Forum geobotanicum is an electronic journal devoted to disseminate information concerning geographical distribution, ecology, morphology, taxonomy and conservation of vascular plants in the European Union with a main focus on middle Europe. It covers from molecular biology to environmental aspects. The focus is to publish original papers, reviews and announcements for the educated generalist as well as the specialist in this broad field. Forum geobotanicum does not aim to supplant existing paper journals, but will be much more flexible in format, publication time and world-wide distribution than paper journals. Many important studies are being currently published in local journals and booklets and some of them are published privately. Hence, these studies will become aware to only a limited readership. Forum geobotanicum will encourage authors of such papers to submit them as special issues of the journal. Moreover, the journal is planning to build up an E-mail-address section to support communication between geobotanists in Europe. The editors are optimistic that this electronic journal will develop to a widely used communication forum that will help to stimulate activities in the entire field of geobotany in middle Europe. To overcome problems of long term archivation and effective taxonomic publication of articles published electronically in Forum geobotanicum, print versions of each volume of the journal and appropriate digital storage devices will be delivered freely to selected university libraries and state libraries in middle Europe.},

  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).},

  abstract  = {A pentaploid taxon from the Pilosella macranthela group was discovered in Lower Franconia/Bavaria which is newly described here as P. macranthela subsp. sylvae-pici. It grows mainly in the Bavarian Bunter Spessart and occurs with three small, isolated stands also in the limestone area of the Main valley and Tauber area. Its habit of growth is intermediate between the furcata and laxicephala types of Pilosellae with epigeal and partly hypogeal stolons and a tendency to form clusters. The upper and lower surfaces of the rosette leaves have stellate hairs. The peduncles and the phyllaries are densely covered with dark glandular hairs with yellowish glandular heads. The lateral teeth of the ligules often are separated by incisions. A tetra- und pentaploid transitional taxon between P. macranthela subsp. sylvae-pici and P. officinarum is described as P. ottonis. P. ottonis is tetra- and pentaploid with up to 7 capitula. It is densely covered with dark stalk glands on phyllaries and resembles forms of P. acutifolia in habit. The phyllaries of P. ottonis are covered with numerous epidermal papillae with a diameter of about 10-20 μm and in this aspect resemble P. macranthela subsp. sylvae-pici and P. glomerata. However, in P. officinarum epidermal papillae are absent. Plants of genetically heterogeneous tetra- and heptaploid P. macranthela have been found outside the Spessart as spontaneous hybrids between P. glomerata and P. officinarum and also occur sporadically without P. glomerata in the vicinity.},

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.},
