    Description
    Global description
     
    Vicia hirsuta is a slender herbaceous plant, pubescent, prostrate or erect by climbing on other plants, reaching 70 cm long. The stem is angular. The stipulated leaves, ending by a branched tendril, are composed of many narrow elongated leaflets. The flowers, small, bluish in color, are grouped into small axillary clusters with peduncle not exceeding the corresponding leaf. The fruit is a hairy pod, short and wide, black when ripe, and containing two spherical seeds.
     
    General habit
     
    Hairy annual herb, slender, drawling to erect, by climbing on other plants, 20 to 70 cm long.
     
    Underground system
     
    Taproot system.
     
    Stem
     
    The stem is slender, angular, with a sparse pubescence.

    Leaf
     
    The leaves are alternate and composite. The petiole is framed by two half halberd stipules, 2 to 5 mm long, entire or with 2 to 3 tines. The leaflets are almost glabrous, linear-oblong, 5 to 20 mm long and 1 to 3 mm wide, arranged in 4 to 10 pairs. The leaf ends with a tendril which is usually branched.
     
    Inflorescence
     
    The flowers are grouped by 3-8 axillary racemes (2-6 cm long) with aristate stalk same length as the leaf or shorter. Inflorescences are located in the upper part of the plant.
     
    Flower

    The calyx is pubescent, 3 mm long, consists of a tube extended by long equal, linear and pointed tines. Papilionaceous corolla, 3 to 5 mm, and bluish white in colour.
     
    Fruit
     
    The fruit is an embossed hairy pod, short oblong, 7 to 10 mm long and 3 to 4 mm wide, finished in beak, pubescent, rarely glabrous, and blackish in color when ripe, containing 2 seeds.
     
    Seed
     
    The seed is spherical, o2 to 3 mm in diameter. The scar from its attachment to the pod is big as a third of its periphery.

        Vicia sativa can be easily confused with other three species of the genus Vicia present in the region V. villosa Roth, V. hirsuta (L.) Gray, V. tetrasperma (L.) Schreb. The main characters to differentiate these species are:
        - V. villosa: flowers in groups of 20 to 40, pod 20 to 30 mm long.
        - V. hirsuta: flowers in groups of 1 to 6, pod 7 to 10 mm long, 2-seeded.
        - V. tetrasperma: flowers in groups of 1 to 6, pod 8 to 15 mm long, containing 3 to 4 seeds.
