Antennaria dimorpha

Antennaria dimorpha is a North American species of flowering plants in the daisy family known by the common name low pussytoes or gray cushion pussytoes.[2] It is native to western Canada (British Columbia, Alberta, Saskatchewan) and the western United States as far south as Riverside County in California and Rio Arriba County in New Mexico. It is generally found in dry areas. There are historical records of the species formerly occurring in northwestern Nebraska, but these populations appear now to be gone.[3]

Antennaria dimorpha is a small mat-forming perennial herb growing in a flat patch from a thick, branching caudex. The spoon-shaped leaves are up to about a centimeter long and green but coated with long, gray hairs. The erect inflorescences are only a few centimeters tall. Each holds a single flower head lined with dark brown and green patched phyllaries. It is dioecious, with male plants bearing heads of staminate flowers and female plants bearing heads of larger pistillate flowers. The fruit is an achene with a long, soft, barbed pappus.
