[Botany of Artemisia].

Artemisia vulgaris L. belongs to the family Compositae, sub-family Corymbiferae. The genus Artemisia groups together almost 200 species, the most of them are native of Eurasia and Northern America steppe regions. Artemisia are wind-pollinated plants, the flowers do not secrete any nectar and are not visited by bees. Two species of Artemisia are widely spread through the Lyon region and are with Ambrosiaceae to blame for the pollinosis in summer and autumn: A. annua and A. vulgaris.
