Antennaria geyeri is a North American species of flowering plant in the family Asteraceae known by the common name pinewoods pussytoes[2] or mountain pussytoes.[3] It is native to the western United States where it grows in woodland and scrub very often on the forest floor under pine trees. It is found in Washington (state) , Oregon, northern California , and northwestern Nevada.[4][3]
Antennaria geyeri is a small perennial herb growing up to about 14 centimeters tall. It produces several erect stems from a branching, woody base, and there is no basal rosette of leaves. The leaves along the stem are lance-shaped, a few centimeters long, and coated in long woolly hairs. The inflorescence bears up to 25 flower heads with coats of woolly white fibers and pink-tipped phyllaries. The species is dioecious, with male plants bearing staminate flowers in their heads and female plants bearing pistillate. The fruit is a hairy achene up to a centimeter long including its long, soft pappus.[2]
The species is named for German botanist Karl Andreas Geyer (1809-1853), who initially discovered the species near Spokane.[5]
