Chenopodiaceae [Amaranthaceae] Chenopodium album var. lanceolatum
Chenopodium album L. var. lanceolatum Muhl. ex Willd.) Coss & Germ.

These plants have been combined with typical album in most recent treatments, but may warrant at least informal recognition (FNA 4) or suggest introgression with C. berlandieri var. boscianum (Y). They differ from typical album (F, St, FNA 4) in their leaves, which are usually lanceolate to narrowly ovate, entire, dark green, glabrous (versus broader rhombic, toothed, glaucous, farinose); inflorescences are more interrupted, with pedicels below some flowers (versus sessile); and seeds are smaller (1-1.2 mm versus 1.3-1.5 mm long). In contrast to album, lanceolatum may be native in North America, and is often associated with vacant lots and roadsides (versus cultivated fields), often with a more sprawling habit. In Ky, these plants do appear distinct sometimes (e.g. JC from HARR for KY), but may be also associated with stress or regrowth after mowing.
