“…Only subgenera Idaeobatus, Dalibarda, and Anoplobatus are predominantly diploid, whereas Dalibardastrum, Malachobatus, and Orobatus are exclusively polyploid (Thompson, 1995(Thompson, , 1997. Hybridization occurs in Rubus between closely related species (Kraft et al, 1996;Naruhashi, 1979Naruhashi, , 1990Steele & Hodgdon, 1963, 1970 and, in some cases, between subgenera (Alice et al, 1997;Gustafsson, 1942;Jennings, 1978;Weber, 2003).…”

“…as species with different values with respect to their fertility and distribution (Focke 1877;Gustafsson 1943). From the 1970's onward, Rubus systematics started with a whole new approach, which was called the 'Weberian Reform' by Holub (1997).…”

“…the expansion of species in these areas which gave rise to large hybrid swarms and polyploid offspring (Stebbins' secondary contacthypothesis (Stebbins 1986)), followed by the stabilisation of morphologically distinct biotypes by apomixis. Already Gustafsson (1943) and Richards (1973) hypothesised this origin in apomict Rubus and Taraxacum species respectively, and recent molecular studies of the evolutionary background of species in Rubus subgen. Rubus largely confirmed this hypothesis (Sochor et al 2015).…”

“…Most apomicts are considered to be of hybrid origin (Gustafsson 1943(Gustafsson , 1947Grant 1971;Richards 1973;Stace 1989, p. 154;Matzke-Hajek 1997;Richards 2003;Paun et al 2006b;Hörandl & Paun 2007;Fehrer et al 2009;Mráz et al 2011), and classification of the apomicts lineages as nothospecies would therefore be a considerable option.

“…Rubus. Most members are tetraploid pseudogamous apomict lineages, but other ploidylevels (triploids, pentaploids and hexaploids) are not uncommon (Gustafsson 1943;Krahulcová et al 2013). The mode of reproduction is highly variable, ranging from obligate sexual reproduction to obligate apomixis, both at the species level as well as at the individual or even floral level (Pratt & Einset 1955;Šarhanová et al 2012).…”

1) A survey of cytological, genetical, and other evidence for phylogenetic differentiation of higher plant groups in Mediterranean and Central European areas is presented. 2) Methods and possible results are demonstrated, using as an example the closely related Rubiaceous genera Cruciata and Valantia, where polyploidy, descending dysploidy, increase of heterochromatin, change from allogamy to autogamy, and from perennials to annuals suggest salient features of geographical and ecological differentiation. 3) The phylogeny of more than 70 other Europe groups of Ferns and Angiosperms from the Mediterranean and Central is briefly discussed in chapters on woody plants, perennials of forest, alpine, and other open habitats, and annuals. 4) The sequence from woody plants to annuals is on the average paralleled by increasing intensity of cytogenetical differentiation (polyploidy, dysploidy, etc.) and evolutionary versatility (instead of evolutionary conservatism), and by decreasing age of groups. Furtheron, there are more Holarctic and Eurasian elements in the former, but more European, Mediterranean and Oriental elements in the later groups. 5) In woody groups our examples suggest ancient affinities between relic Macaronesian resp. Colchic laurel forest elements and even more primitive Southeast‐Asian relatives (Prunus subg. Laurocerasus), origin of Mediterranean sclerophylls form laurel forest progenitors related to species in Macaronesia and East Asia (Viburnum sect. Tinus), and close affinities between Mediterranean evergreens and European summergreens (Rubus sect. Moriferi); these phenomena probably date back from the early to the later Tertiary. 6) Examples from perennial groups stress the importance of Macaronesian, Mediterranean, and Oriental areas as centers for old and primary geographical differentiation (West/East etc.) as well as for ecological radiation from laurel, sclerophyll and temperate forest elements to those of open, warm and/or cold (alpine‐arctic) habitats, probably from Mid‐Tertiary onward (Polystichum setiferum‐P. lonchitis. Lotus corniculatus agg., Cyclamen purpurascens, Cruciata‐Valantia, Galium mollugo agg., Campanula subsect. Heterophylla, Brachypodium, Dactylis glomerata agg., etc.). 7) The repeated origin of annual from perennial groups (Anagallis subg. Anagallis. Cruciata‐Valantia, Carthamus, Calendula, Crepis, Brachypodium, etc.) and their further differentiation was centered in Oriental, southeastern and southwestern Mediterranean areas, and seems to have been furthered by succsssive xerothermic periods since the later Tertiary. 8) During the Pleistocene and its extreme climatic changes European floras became depauperate : Mediterranean areas then served as most important centers of conservation for many primitive progenitors of younger Central European elements. This has been demonstrated for numerous groups from forest (e. g. Polypodium vulgare agg., Paeonia, Rubus sect. Morveri. Lamiastrum, etc.), open (Pulsatilla vulgaris agg., Pinguicula sect. Pinguicula, Veronica hederifolia agg.,...
