Cistanthe is a plant genus which includes most plants known as pussypaws. These are small, succulent flowering plants which often bear brightly colored flowers, though they vary quite a bit between species in appearance. Some species have flowers that are tightly packed into fluffy-looking inflorescences, the trait that gives them their common name. Many are adapted to arid environments, with some able to withstand climates that almost completely lack rainfall. Cistanthe was a genus created to segregate several species previously classified in Calandrinia. Several species from other closely related genera have been moved into Cistanthe as well.
