Erythranthe microphylla is a California native annual found in wet meadows, seeps, and streambanks from coastal to mountain regions at elevations of 20 to 1,700 meters.

Its small elliptic to nearly round leaves measure 5 to 30 millimeters long, growing in opposite pairs along the stem. The fruit is 6 to 9 millimeters long, developing in an asymmetrically swollen calyx with unequal lobes.
