Description of Fumaria
Annuals with erect, diffuse or climbing stems. Leaves cauline, 2- to 4-pinnatisect. Inflorescence racemose, bracteate, with short pedicels. Sepals 2, lateral. Corolla zygomorphic, consisting of a spurred upper petal, 2 inner petals, and a lower one. Fruit 1-seeded, indehiscent, showing 2 apical pits in the mesocarp when dry. In W. Europe mostly weeds of arable land, but in S. & E. Europe found also in rocky, sandy and grassy places. Measurments are meant for typical specimens growing in their natural habitat. Fumaria can form reduced, undeveloped or dwarfed structures in impoverished habitats.
