3. ERŅDIUM L'Her.; Ait. Hort. Kew. 2: 414. 1789.

Herbs, generally with jointed nodes, opposite or alternate stipulate leaves, and axillary umbellate nearly regular flowers. Sepals 5, imbricated. Petals 5, hypogynous, imbricated, the 2 upper slightly smaller. Glands 5. Anther-bearing stamens 5, alternating with as many sterile filaments. Ovary 5-lobed, 5-celled, beaked by the united styles, the beak terminating in 5 stigmas; ovules 2 in each cavity. Capsule-lobes I-seeded, the styles elastically dehiscent and coiled spirally at maturity, villous-bearded on the inner side. Seeds not reticulate. [Greek, a heron, from the resemblance of the fruit to its beak and bill.]

About 60 species, widely distributed in temperate and warm regions. There are three native species in the southwest and several exotic ones have been collected on ballast at the seaports. Type species: Erodium crassifolium Soland.
