Pectocarya

Pectocarya is a plant genus of about 15 species in the family Boraginaceae. Plants in this genus are known generally as combseeds. They are small annual plants which bear tiny white flowers no more than 3 millimeters in diameter. Their fruits are nutlets which often have small projections that look like the teeth of a comb, hence their common name. The nutlets usually come in clusters of four. These plants are found mainly in western North America.
