Erythranthe nasuta is a native California annual in the Phrymaceae family, recognized by annual with flowers distributed from base to top.
Erythranthe nasuta is a native annual herb found in seeps, rock outcrops, streams, and creeks at elevations of 600 to 3,200 meters. Flowering from March to July, this plant produces yellow flowers with a tube-throat 8 to 12 millimeters long, emerging just slightly beyond the calyx. Growing 2 to 35 centimeters tall with fibrous roots, it has an essentially smooth stem with glandular hairs near the nodes. Its leaves are elliptic to ovate, 3 to 25 millimeters long, with petioles 3 to 35 millimeters in length and pairs of leaves at each node that remain unfused. Fruits develop 4 to 10 millimeters long, with a calyx that becomes asymmetrically swollen, featuring unequal lobes with the lowest two curving upward.
