It is the most common species of the genus Fumaria in Western and Central Europe. Taxonomy - It was first formally described by the Swedish botanist Carl Linnaeus in his seminal publication 'Species Plantarum' on page 700, in 1753.[5][6] Flower and leaves of Fumaria officinalis The "smoky" or "fumy" origin of its name comes from the translucent color of its flowers, giving them the appearance of smoke or of hanging in smoke, and the slightly gray-blue haze color of its foliage, also resembling smoke coming from the ground, especially after morning dew.
