Chenopodium album Linnaeus var. missouriense (Aellen) Bassett & Crompton
(Lamb's Quarters)

Family: Amaranthaceae

Status: Native

Synonyms:
Chenopodium missouriense Aellen

Chenopodium album var. missouriense is an erect herb with sinuate or dentate leaves that are not stinky. The leaves are sparsely farinose underneath. The glomerules are densely packed and 2-4mm in diameter. There are five sepals which are farinose, keeled and enclose the seed. The pericarp (seed covering) is densely adherent such that the seed tears before the pericarp will separate. This variety of Chenopodium album is the native one, and is distinguished by stiff panicles, dense glomerules without interrupted areas, and purplish nodes. Chenopodium album var. missouriense is found at the roadside.
