Munz's sulphur flower

Family: Polygonaceae · Type: perennial · Native

Munz's sulphur flower is a California native perennial found in the Transverse Ranges and San Jacinto Mountains on sandy or gravelly sites at elevations of 1,500 to 2,600 meters. Flowering from June to September, this plant produces distinctive yellow flowers 3 to 8 millimeters long in umbel-like clusters. Growing as a low-spreading mat 3 to 6 decimeters in diameter, it forms compact ground-covering stems 10 to 20 centimeters tall that are generally covered in soft, woolly hairs. Its leaves are relatively small, measuring 1 to 2 centimeters long and 0.5 to 1 centimeter wide, with dense tomentose surfaces that give the plant a soft, grayish appearance. The plant's intricate branched inflorescences feature involucre tubes 2 to 3 millimeters long with small teeth 1 to 2 millimeters in length.
