About Asperugo procumbens L.
Asperugo procumbens, commonly called German madwort, is the only species in the monotypic plant genus Asperugo. It is native to Europe and the temperate regions of Asia, and has been introduced to other areas by human activity. This species is an annual plant, with stems that reach 20 to 60 centimeters in length. Stems grow trailing along the ground, and do not produce roots at their nodes. Leaves are most commonly arranged alternately along the stems, though they may be arranged oppositely on the stem sections near the stem tips.
