Pygmy lotus is a rare (CNPS 1B.3) California native perennial found in southeastern Peninsular Ranges and southwestern Desert Southern California, especially San Diego County, in creosote-bush scrub and pinyon/juniper woodland at elevations of 600 to 1,200 meters. Flowering from March to June, this plant produces delicate yellow flowers with a distinctive keel slightly longer than other petals. Growing with ascending or sprawling rush-like stems 10 to 200 centimeters tall and bushy in form, it develops sparse, early-deciduous subpalmate leaves with three small elliptic leaflets. Its leaves are notably minimal, with leaflets measuring just 2 to 5 millimeters long and often appearing almost absent. The fruit is an interesting curved, oblong structure 6 to 9 millimeters long with a distinctive 2 to 3 millimeter curved beak.
