Atriplex patula L., a member of the Chenopodiaceae family, is a circumboreal annual herb native to Europe and naturalized in many temperate regions. It was first described by Linnaeus in 1753 and is commonly known as Common Orache. The species is characterized by herbaceous, spreading growth and subdeltoid-lanceolate leaves. Atriplex patula is often found in ruderal habitats and has a wide distribution across North America, Greenland, and parts of Europe, including the Açores and Portugal Continental. It is closely related to other Atriplex species such as A. prostrata and A. elongata, which share similar morphological traits, particularly in fruiting bracts.

Description

Atriplex patula is distinguished by its herbaceous fruiting bracts, which are indistinctly veined and often have dentate margins. It is part of the section Teutliopsis, which includes species with similar bract morphology. The plant has been studied in relation to other Atriplex species, particularly A. elongata and A. prostrata, which were previously misapplied with the name A. hastata. Atriplex patula is a common ruderal species, often found in disturbed soils and cultivated areas. Its wide distribution includes regions such as Greenland, Canada, and various European territories. The species was lectotypified by Taschereau in 1972 based on the original Linnaean description.
