Stony creek spurge is a rare (CNPS 1B.2) California native annual found in northern Sacramento Valley counties of Glenn and Tehama in sandy or stony ground at elevations below 100 meters. Flowering from May to September, this plant produces small white flowers with distinctive gland appendages wider than the glands themselves. Growing with hairy stems in low, spreading formations, it maintains a delicate and compact structure. Its leaves are small, less than 10 millimeters long, with distinctive ovate blades that contribute to its understated appearance. The plant's subtle characteristics make it a unique component of its sparse, rocky habitat.
