Atriplex patula L.
Common Name: SPEARSCALE
Coefficient of Conservatism: *
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Ad A-Forb

Introduced from Eurasia to roadsides, railroads, gardens, and disturbed ground generally, thriving where salting of streets and highways has killed the competition; also in marshy ground. First collected in Keweenaw Co. in 1885.

Often only the lowest leaves have the distinctive, forward pointing lobes, and some collections lack lobes. Such narrow-leaved plants lacking the lobes may resemble A. littoralis L., which differs in having the bracteoles surrounding the seeds spongy-thickened towards the base at maturity.
