Calyptridium parryi, synonym Cistanthe parryi, is a species of flowering plant in the family Montiaceae. It is known by the common name Parry's pussypaws. It is native to the southwestern United States and Baja California. It is a small annual herb producing spreading stems up to about 11 centimeters long. There is a basal rosette of small, thick, spoon-shaped leaves no more than about 3 centimeters long, with many along the stems as well. The inflorescence is a cluster a few centimeters wide, with each bearing three white petals surrounded by a few thin sepals. The fruit is a capsule less than a centimeter wide.
Calyptridium pulchellum, synonym Cistanthe pulchella, is a rare species of flowering plant in the family Montiaceae. It is known by the common name mariposa pussypaws. It is endemic to the Sierra Nevada foothills of central California, where it is known from only a few scattered occurrences. It grows on barren patches of granite gravel in woodland and grasslands.
