description
Appearance and foliage leaf
Petroselinum segetum grows as a slender, annual or biennial herbaceous plant . The taproot is slender and spindle-shaped. The above-ground parts of the plant are bare and more or less frosted. It reaches heights of growth of up to 100 centimeters. The upright, not hollow, stalk-round, striped stem is branched spreading.
The leaves , arranged alternately on the stem near the plant base, have a thin petiole. The leaf blade, linear in outline, is simply pinnate . The leaf blades consist of four to twelve pairs of almost sessile, with a length of 0.5 to 3.5 centimeters almost circular to lanceolate, egg-shaped sections, whose sawn or sometimes slightly lobed edges are thickened and whose blunt teeth have a hard edge and a 0 , 5 millimeter long spike tip and tough and bent up.
Inflorescence, flower and fruit
On a long inflorescence stem stands a very irregular double-gold inflorescence with two to ten smooth, unequal, about 3 centimeters long rays, each having an awl bract and two to five awl bracts.
The almost sessile to long-stalked flowers are hermaphroditic, radial symmetry . The sepals are small. The petals are white.
The fruit stalks are short to 15 millimeters long. The split fruit disintegrates into two egg-shaped, laterally flattened, smooth partial fruits with a length of 2.5 to 3 millimeters.
Chromosome number
The number of chromosomes is 2n = 18.
Similar species
Petroselinum segetum can easily be confused with Sison amomum , which has extremely different lengths of umbellate rays and more leaf sections. It has thicker main ribs on the cleft fruits; it also lacks the characteristic smell.
Occurrence
Petroselinum segetum is native to Europe from the United Kingdom via the Netherlands , Belgium southwards via France to Italy , Spain and Portugal . It inhabits unused or grazed agricultural land, pastures , rows of hedges and river banks in the United Kingdom .
