Family: Chenopodiaceae · Type: Herb · Native

Conservation status: CNPS 1B.2

Atriplex erecticaulis (Earlimart orach) is a native California herb in the Chenopodiaceae family, recognized by cordate leaf bases and central tooth equal to or smaller than others distinguish from var. cordulata.

Earlimart orach is a rare (CNPS 1B.2) California native annual found in the San Joaquin Valley in saline or alkaline soils at elevations below 100 meters. Flowering from August to September, this plant produces small, unremarkable flowers with distinctive fan-shaped or deltate bracts that become prominent in fruit. Growing to about 30 to 50 centimeters tall with erect stems, it develops a delicate, upright branching structure. Its leaves are likely small and somewhat succulent, adapting to the challenging saline environments where it grows. The fruit bracts are particularly noteworthy, with a central tooth that is typically shorter than the surrounding edges, a key identifying characteristic of this rare variety.
