Volunteer lentil
Lens esculentum (Lens culinaris)

Overview: Lens culinaris is an erect, pale green annual herb up to 75 cm tall. Its main stem is square in cross-section, and from it many branches extend.
Leaves: The pinnately compound leaves are arranged alternately along the stem. Each leaf consists of 5-16 leaflets which are inserted along the leaf’s central axis (the rachis).
Flowers: The stalked flowers are arranged along an unbranched axis (a raceme). The racemes are about 7-flowered and axillary (arising from the point between the main stem and a leaf). The flowers are pale blue, white or pink and are papilionaceous, typical of species belonging to the Leguminosae subfamily Papilionoideae, and resemble, for example, the pea (Pisum sativum) flower. Each flower has 10 stamens (male reproductive organs) 9 of which are fused into a partial tube, with the tenth stamen free. The ovary (female reproductive organ) is positioned above the sepals, petals and stamens. The style is inflexed (bent inwards) and its inner surface is bearded.
Fruit: The fruit is a 6-20 mm long x 3-12 mm wide pod containing up to 3 seeds. The seeds are lens-shaped, 2-9 mm long x 2-3 mm wide and can be grey, green, brownish green, pale red speckled with black or pure black in colour.
