Chenopodium californicum is a species of flowering plant in the amaranth family known by the common names California Goosefoot and (ambiguously) "Indian lettuce".
This is a perennial herb producing a number of decumbent to erect stems which approach a meter in maximum height when growing upright. It grows from a thick, fleshy caudex. When there are many stems the plant may form a clump or mat. The leaves grow on long petioles and are triangular or arrowhead-shaped and up to about 10 centimeters long. The edges are deeply and sharply toothed. 
The inflorescences are spherical clusters dotted along an inflorescence-like spike. Each dense cluster contains several rounded flowers, with each flower a series of flat lobes covering the developing fruit. The fruit is a reddish utricle layered around the surface of the seed.
California goosefoot was used for a variety of purposes by Native Americans including use as a medicine and a source of soap, in addition to the use of the seeds for flour and the leaves and shoots as a cooked vegetable.
