“…Such a karyotype was shown for V. amphicarpa by Sveschnikova (1940) and for this species and a Moroccan strain of V. sativa by Yamamoto (1966). According to Mettin and Hanelt (1964) only V. cordata has this chromosome number. They found two karyotypes in this species: one possessed a long metacentric, two subacrocentrics and two acrocentrics; the other had a subacrocentric and four acrocentrics.…”

“…According to Mettin (1961), Mettin and Hanelt (1964) and Hanelt and Mettin (1966) V. pilosa, V. incisa and V. amphicarpa all have this chromosome number, and other workers have reported it for V. sativa as well.…”

“…Chromosomes III -VI. This was the convention used by Coutinho (1940), and we consider it more useful than that of Mettin and Hanelt (1964), which was based on length alone. In our account we use the term metacentric to cover the m-chromosomes of Levan, Fredga and Sandberg (1965), viz.…”

“…differing because of the different geographical areas of study and the different taxonomic aims and preferences of the authors concerned, it is clear that most modern workers consider that at least six major taxa can be recognized. In the most thorough studies so far carried out Mettin and Hanelt (1964) recognized six species, delimited on both morphological and karyotypic characteristics. Their species are V. amphicarpa Dorthes, V. incisa Bieb., V. cordata Wulfen ex Hoppe, V. macrocarpa (Moris) Bertol., V. sativa L.s.s.…”

SUMMARYPrevious accounts of the chromosome complement of members of the Vicia sativa aggregate and of V. lathyroides are reviewed, and the results of a new survey of 122 strains belonging to four taxa presented. Significant variation in chromosome morphology within each of the three segregates of V. sativa agg. was found; in V. segetalis both zn = 10 and 2n = 12 was encountered among the cultivated material. In wild V. lathyroides also both 2w = 10 and zn = 12 populations were found. Reasons are given for considering that this group of vetches shows a reductional evolutionarv' series 2n = 14 >2K = 12--*2n -10, and the inter-relationships of these three karyotypes are discussed. In addition two counts of 2w = 14 are reported for wild Turkish strains of V. atnphicarpa.

In Fortführung früherer Untersuchungen karyologisch bisher nicht bekannter Vicia‐Arten werden jetzt folgende weitere Sippen der Gattung behandelt: Erstbestimmungen — V. meyeri BOISS. (2n = 14), V. pubescens (DC.) LINK (2n = 14), V. graminea SM. (2n = 14), V. ramuliflora (MAXIM.) OHWI (2n = 28), V. semiglabra RUPR. ex BOISS. asp. caucasica (EKVTIM.) RADZHI (2n = 10), V. semenovii (RGL. et HERD.) FEDTSCH. (2n = 12), V. costata LDB. (2n = 12), V. hajastana GROSSH. (2n = 10). Nachuntersuchungen — V. tenuissima (M. BIEB.) SCHINZ et THELL. (2n = 14), V. benghalensis L. (2n = 14), V. peregrina L. (2n = 14), V. lathyroides L. (2n = 12). Für sämtliche Arten werden kurze Hinweise auf ihre Karyotypen und zu ihrer systematischen Stellung gegeben, wobei auf teilweise vorliegende widersprüchliche Literaturangaben eingegangen wird (V. benghalensis, V. peregrina, V. lathyroides). Die für die Sippen der Untergattung Ervum mitgeteilten karyologischen Befunde bestätigen die Einheitlichkeit dieser Gruppe bezüglich der Chromosomenzahl (2n = 14) und der relativ ursprünglichen Chromosomenstruktur. Neu ist der Fund eines abgeleiteten 10‐chromosomigen Karyotyps (V. semiglabra) innerhalb der im allgemeinen als relativ ursprünglich angesehenen Untergattung Cracca. In diesem Verwandtschaftskreis wurde auch eine neue polyploide Sippe (V. ramuliflora) gefunden und eine Zusammenstellung der bisher bekannten polyploiden Vertreter der Gattung gegeben, deren Vorkommen auf perennierende Arten des Subgen. Cracca beschränkt ist. Die meisten Sippen sind durch deutlich abgrenzbare Karyotypen gekennzeichnet, die sich z. T. auch in unterschiedlichen Chromosomengrößen äußern (überdurchschnittlich groß: V. hajastana, V. peregrina; besonders klein: V. ramuliflora, V. lathyroides). Diese starke karyologische Differenzierung bezieht sich anscheinend auch auf die neuweltlichen Vertreter der Gattung, von denen erstmalig V. graminea und eine als „V. selloi”︁ bezeichnete Herkunft untersucht wurden. Verallgemeinernd kann gesagt werden, daß neben den traditionellen morphologischen Merkmalen die Chromosomenzahl und ‐struktur in der Gattung Vicia sich als außerordentlich brauchbar für systematische Betrachtungen erwiesen haben, so wie das auch für viele andere Pflanzengruppen zutrifft. Deshalb halten wir weitere cytotaxonomische Studien für besonders geeignet, die Evolution und die ihr zugrunde liegenden Mechanismen in der Gattung aufzuklären. Eine sich darauf beziehende Auswertung der bisher vorliegenden Fakten bleibt späteren Untersuchungen vorbehalten.

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.,...
