As a result of our
research during 1983-2012 the centres of formation of wild lupine species and
those of diversity of cultivated species were refined. The system of taxonomic
and eco-geographical classification of narrow-leaved, yellow and white lupine
was developed. The initial evolution of lupines we associate with the theory of
continental drift developed by A. Wegener (1912). A common primary centre of formation of new
forms of the early ancestors of lupines very likely existed before the
divergence of the continents of Laurasia, and predominantly in its western part
which subsequently became North America. It is confirmed by today's presence on
the American continent of a large number of lupine species. Two secondary
centres of diversity evolved , after the divergence of continents, in the
Americas and the Mediterranean. The most
significant factors in the evolution and spread of lupine were continental drift,
volcanoes, the earth's tilt, ocean currents and human activities. The Balkan
Peninsula is a centre of diversity of white lupine and the Iberian - of yellow
lupine. Criteria for a number of
taxa within the genus Lupinus L. (subgenera, subspecies,
varieties, forms) were suggested. As a result some new taxa were established.
Due to the significant differences between lupines of two hemispheres, we revised
two subgenera of Lupinus and suggested a new classification :
I. Subgen. Platycarpos (Wats.) Kurl. 1989, Bull. N.I. Vavilov Inst. Plant Industry 193:24. - §2. PLATYCARPOS S. Wats. 1873, Proc. Amer. Acad. Arts Sci. 8:522; B. Platycarpos Aschers. et Graebn. 1907, Mitteleurop. Fl. 6,2:232; §1. LUPINUS S.Wars. 1873, l.c. 518, p.max.p.;A. Eulupinus Aschers. et Graebn. 1907, l.c. 221, p.p.- New World's or flat-fruited lupines. Geographic distribution: the Americas.
This subgenus includes several hundreds of species requiring further analysis
of their authenticity. The type of
L. densiflorus Benth.
II. Subgen. Lupinus. 1989, Bull. N.I. Vavilov Inst. Plant Industry 193:23. - A. Eulupinus
Aschers. et Graebn. 1907, p.min.p. - Old World's lupins. Geographic distribution: Mediterranean and
Africa. Some species are cultivated. The type of subgenus: L. albus L.
