Typus: Herb. Linn. No 898-7 (LINN).

Fifure - Lupinus angustifolius L. (holotype).

Plants are 20-150 cm high. Stalks are sparsely sericeous, with numerous lateral branches. Leaves are developed from 5-9 linear-lanceolate or narrow-linear leaflets, 20-40 х 2,5 mm in size, the upper surface is glabrous, the lower surface is sericeous. Stipules are linear and linear-lanceolate. The inflorescence is dense, almost sedentary, 5-20 cm long, placed on a short floral pedicle. Flowers are 11-15 mm long, almost sedentary, lower flowers are alternate, upper ones more or less subverticilate inside. Floral bracts are small-sized, easily falling. The calyx is bilabiate, profoundly bipartite, the lower lip is longer, entire or irregularly two- or three-toothed. The corolla is blue, violet, less frequently pink and white. Pods are 35-50 х 7-10 mm in size, oblong, slightly inflated, 4- or 7-seeded, with oblique partitions between seeds. The seed is 4-8 х 3-7 х 3-6 mm, globular, with smooth testa, variously coloured, with a triangular spot and a stria close to the hilum. 2n = 40.
Occurs on meadows, among rocks, in bushes, on seaside sands and near reservoirs, along the roads and, as a weed, in the field. Tends to grow on well-ventilated soils. Widespread in all Mediterranean countries and also in Asia Minor, Transcaucasia and Iran. Naturalized in Southern Africa and Southwest Australia. Widely cultivated in Northern Europe (Germany, Holland, Poland, CIS), in the southeast part of USA and in New Zealand.
It is a rather polymorphic species. The variability of characters depends on eco-geographic conditions. Wild-growing races have, as a rule, narrow pods, smaller-sized leaflets and seeds as well as lower plant height. The size of seeds and their colouring vary on all area of growing. Large-seeded plants usually occur closer to arable soils, while small-seeded ones on inshore sands and slopes. The species is described using a large cultivated form. The colouring of seeds varies from dark grey (almost black) with light spots and specks of miscellaneous size, grayish brown and brown up to light grey and white. Usually seeds with coloured testa correlate with cyan and pink flowers. In these two characters (traits) homologous variability is observed. Unpigmented (white) seeds are typical for white-flowered and lilac plants. These combinations of characters do not demonstrate any geographic arrangement. There is no abrupt gap between cultivated and wild forms. On the contrary, transition between them appears very smooth. Therefore there is nothing to justify the existence of two species (L. linifolius Roth. and L. opsianthus Atab. et Mais.) and also two subspecies (subsp. angustifolius and subsp. reticulatus (Desv.) Franko et Silva.) differing only on in the width of leaflets and the size of seeds (quantitative characters). In our opinion, it would be more correct to subdivide this species in a different way.
Using the developed criteria of intraspecific taxa, the spreading of VIR’s blue lupin collection disclosed 13 varieties of L. angustifolius L. distinctly differing from each other by the colour of seeds and the corolla.
Variations in the colour of cotyledons, vegetative parts and carina have been used for identification of 12 subvarieties.
Besides, the plants with determined branching and fascicular stems are described as 8 separate forms.

The quantity of new intraspecific taxa of Lupinus angustigolius L., and specially its subvarietas and forms, can be greater in the process of further investigation of its intraspecific diversity.
