Dysphania
Included in Chenopodium in Michigan Flora.
This is a segregate from Chenopodium including (in Michigan) all the species that are not farinose, and have either glands or inflorescence branches ending in spines. The glandular species are aromatic, and some have been utilized medicinally.
1. Leaves (and rest of plant) neither glandular nor pubescent; at least the upper branches ending in subulate, delicate, spine-like points: flowers solitary, in axils of branches.
1. Leaves with orange resinous glands or gland-tipped hairs at least beneath, bruised plant strongly aromatic; without spine-like branches; flowers in small clusters.
2. Leaf blades ± copiously covered with short spreading gland-tipped hairs on both sides; stem with abundant stalked glands; flowers in branched axillary cymes.
2. Leaf blades with mostly sessile glands on the underside; stem glabrous or pubescent, but not or only sparsely glandular; flowers in axillary (and terminal in D. ambrosioides) spike-like inflorescences.
3. Perianth lacking glands; leaves with only sessile glands beneath (except sometimes some appressed hairs on the main veins).
3. Perianth with sessile glands; leaves with abundant spreading hairs beneath, especially on the veins.
