botanist Dioscorides, from a Persian name for lucerne, or medick.

Sativa (L) Planted, cultivated, not wild, sown.

Falcata (L) Sickle-shaped

General description:- Very variable, usually hairy perennial.

Stem:-

1) 20-70 cm. procumbent.

Leaves:-

1) Leaflets, obovate to almost linear, long-cuneate, dentate at the apex.

2) Stipules, lanceolate to linear-subulate, entire or dentate at the base.

Flowers:-

1) Peduncles, longer than the subtending leaf.

2) Inflorescence, a dense, 8-25 flowered raceme.

3) Corolla, bright yellow.

Fruit:-

1) Legume nearly straight, falcate or in a spiral of 1-3 turns with a hole through the

centre, glabrous, pubescent or glandular, not spiny; transverse veins

anastomosing and forming a transversely or radially elongated network.

Key features:-

1) Inflorescence, a dense, 8-25 flowered raceme.

2) Legume, nearly straight to falcate.

Very variable, particularly in S. and S.E. Europe, where a number of distinct species

have been recognized. In view of the overall variation and the known frequency of

hybridization between M. sativa and M. falcata, two of the most distinct taxa, it

seems best to treat them all as subspecies. Hybrids between subspecies with

bluish and yellow corollas often have green or almost black corollas. The best-

known of these is subsp. falcata x subsp. sativa & M. x varia 1)
