Lupinus luteus, Linn. Yellow Lupine. Fig. 2218. St. erect, nearly simple, hairy, 2 ft. high: 1fts. lanceolate, acute, hairy: fls. on pubescent stalks longer than the lvs., verticillate, yellow, fragrant: pod oblong, flat. June, July. S. Eu. B.M. 140.—Succeeds in the poorest soil. Useful for cut-fls., for the border, for fodder or for plowing under to improve sandy soils. As a fodder, it may be fed green or as hay.

Description

Distribution and common names: W Iberia, scattered pan-Mediterranean, native or semi-cult.; elsewhere, cult.

"Yellow lupin".

Plants are 20-80 cm high, rosetted in the beginning and becoming erect in subsequent, with vigorous basal branching. Stems are short and hirsute, with intesive branching in the lower part. The leaf consists of 7-9 (11) ovate-oblong or lanceolate leaflets, prolated at the basis, densely villous on both sides, sized 30-60 х 8-15 mm. Stipules of the rosetted leaves are crescent and chuffy on stalks, linear-obovate in shape. The inflorescence is an elongated truss, 5-25 cm long, set on a peduncle of 5-12 cm. Flowers are verticillate, odorous. Floral bracts are small-sized, obovate, silky-pubescent, easily falling. The upper labium of a calyx is bipartite, the lower one has 3 small denticles. The corolla is 14-16 mm long, bright goldish-yellow in color. Pods are elongated, 40-60 х 10-14 mm, densely villous, 4-6-seeded, with oblique partitions between seeds. Seeds are 5,5-6,5 mm in diameter, spherical-reniform, oblate, variable colouring - from pinkish, brown and yellowish up to dark-violet and mottled.

Usually this species is considered as an annual one, but in wild environments it is sometimes possible to find two- and four-year plants. The variability of characters in this species is less expressed than in L.angustifolius; however a homologous series can be modeled on the color of seeds, which is more or less similar to L. angustifolius. 2n=52 .

The scheme of classification of Lupinus luteus L.

Using combinations of such characters as the color of the corolla, the carina's edge, vegetative organs and seeds, 18 varieties, 4 subvarieties and 6 forms have been identified.
