Boerhavia, the spiderlings or hogweeds, is a genus of about 40 species of annual or perennial herbaceous plants in the four o'clock flower family, Nyctaginaceae. The common name refers to the appearance of a spider or spider's web given by the numerous long, slender and interlocking stems of the inflorescences. The genus was named for Herman Boerhaave, a Dutch botanist, and the genus name is frequently misspelled "Boerhaavia".
They are native to mostly warm tropical areas.
