About Antennaria geyeri A.Gray
Antennaria geyeri A.Gray is a North American flowering plant species in the Asteraceae family, commonly known as pinewoods pussytoes or mountain pussytoes. 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 occurs in Washington, Oregon, northern California, and northwestern Nevada. Antennaria geyeri is a small perennial herb that grows to around 14 centimeters tall. It produces several erect stems from a branching, woody base, and does not grow a basal rosette of leaves. The leaves along the stem are lance-shaped, a few centimeters long, and covered in long woolly hairs. Its inflorescence holds up to 25 flower heads, which have coats of woolly white fibers and pink-tipped phyllaries. This species is dioecious: male plants produce staminate flowers in their heads, while female plants produce pistillate flowers. The fruit is a hairy achene that reaches up to one centimeter in length when its long, soft pappus is included. The species is named for German botanist Karl Andreas Geyer (1809-1853), who first discovered it near Spokane.
