Cistanthe

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.

The genus has a disjunct distribution, with species in California and northeastern Mexico, on the Mexican Pacific Islands, and western and southern South America from Peru to northern and central Chile to northwestern and southern Argentina.

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.
