Calyptridium umbellatum, synonym Cistanthe umbellata, is a species of flowering plant in the montia family known by the common name Mount Hood pussypaws or — especially outside the Pacific Northwest — simply pussy-paws.

A small subgroup of C. umbellatum are located in the Zayante Sandhills, a biological island in the Santa Cruz Mountains.

[6] These individuals reside on a singular hill in the entirety of the sandhills, and their frail petals and loose seeds allow for easy wind dispersal.

It is a perennial herb forming generally two or more basal rosettes of thick, spoon-shaped leaves each a few centimeters long.

The inflorescence arises from the rosette, a dense, spherical umbel of rounded sepals and four small petals.
