[Wikipedia] Native to North Africa, Europe, Asia; Description, Taxonomy: Fumaria officinalis, the common fumitory, drug fumitory or earth smoke, is a herbaceous annual flowering plant in the poppy family Papaveraceae. It is the most common species of the genus Fumaria in Western and Central Europe.
It is an herbaceous annual plant that grows weakly erect and scrambling, with stalks about 10?50 cm (3.9?19.7 in) long. It has slender green leaves. Its pink 7?9 mm (0.28?0.35 in) flowers appear from April to October in the northern hemisphere, or May to September in the UK. They are two lipped and spurred, with sepals running a quarter the length of the petals. The plant commonly has more than 20 and up to 60 flowers per spike. The fruit is an achene containing one seed. It is approximately globular, slightly wider than high and with an apical notch. It contains alkaloids, potassium salts, and tannins and is also a source of fumaric acid.
It was first formally described by the Swedish botanist Carl Linnaeus in his seminal publication 'Species Plantarum' on page 700, in 1753.
There are 2 known subspecies:
Fumaria officinalis subsp. cilicica (Hausskn.) Lidén
Fumaria officinalis subsp. wirtgenii (Koch) Arcang.
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.
Distribution and habitat
It is native to temperate regions of North Africa, Europe and parts of Western Asia. (contributed by Mary Ann Machi)
