GOLDEN CORYDALIS-Corydalis aurea Wilid.

DESCRIPTION-Low bluish green fleshy biennial or short lived perennial, reproducing by seeds. The weak hairless stems, diffusely branched and spreading from the base, are often prostrate with the tips turning upward. The leaves are dissected into many small segments.

The narrow bright yellow flowers, 3/8 to 3/4 inch long, have a short conspicuous spur at the base, and 2 sepals. They occur in short spikelike flower branches at the end of the stems. The bluish green seed pods are usually curved, and often hang downward. They are cylindrical, 1/2 to 1 inch long, and produce many black and shining seeds. The smooth seeds have rounded margins, and are about 1/12 inch in diameter.

DISTRIBUTION-Golden corydalis occurs throughout the state, except in the extreme southwestern part. Common in moist disturbed soil of roadsides, open flats, river bottoms, stream banks, rocky slopes, in creosote-mesquite desert, sagebrush, grassland, oak-woodland, pine forests, and spruce-fir associations; flowering March to August.

POISONOUS PROPERTIES-Golden corydalis contains 10 alkaloids, some of which are known to be poisonous. It may cause some livestock losses in Arizona.
