Seed Storage
The storage behavior of this species is orthodox (desiccation-tolerant seeds); dry to 15-20% eRH and store at -20 °C.
Germination requirements
The seeds of this species are not dormant. Sterilize seeds before placing them on wet germination paper. Place seeds for two weeks in 4 ºC to germinate uniformly. Then germinate under an alternating temperature regime of 15/20 ºC (the higher temperature for 16 hours in light and the lower one for eight hours in dark).
Morphology
Fruit: Pods short cylindric, with glandular hairs, tubercular or spiny; 3-4.5 coils; with shallow farrow between marginal and submarginal vein; lateral veins on coil surface strongly branched, moderately curved; with 0.5-3.5 mm long spine.
Fruit size: Diameter: 5.5-8
Seed: Kidney-shaped but often flattened along edge adjacent to radicle, seed coat smooth, and yellow to light brown
Seed size:
1000 seed weight:
Biological features
Life form: Herbaceous, annual, decumbent to ascending.
Inflorescences and flower type and pollination mechanisms: Flowers in axillary pedunculate racemes, hermaphrodite, zygomorphic and asymmetric; corolla (composed of banner: upper large petal, wings: two petals adjacent to the banner, and Keel: two bottom petals); stamens are always ten in number, and their filaments are fused in a group of nine stamens plus one separate stamen (9+1). Plant monoecious, self-pollinate with 10% cross-pollination, which is carried out by insects.

Time of seed ripening:
Seed dispersal methods: The seeds are displaced by weight. Pods move by attaching to the wool and hair of animals.
Geographical distribution:
Distribution in Iran: Kermanshah and Lorestan.
