"Antennaria racemosa" is a species of flowering plant in the daisy family known by the common name raceme pussytoes. It is native to western North America from British Columbia and Alberta to northern California to Wyoming. It grows in mountain forests, generally in moist, partially shaded areas, and often colonizes bare patches of mineral-rich soil, including disturbed areas. This is a glandular perennial herb which may be small, woolly, and matted to nearly hairless and erect to heights near half a meter. It forms basal patches of oval-shaped leaves 3 to 10 centimeters long, fuzzy on the undersides and shiny green above. The patches are connected with stolons covered in leaves. The erect stem bears an inflorescence which can be shaped like a raceme, especially in higher elevations, containing several flower heads. The species is dioecious, with male and female plants producing different types of flowers in the heads. The fruit is an achene with a body only about a millimeter long attached to a soft pappus up to 7 millimeters long. The pappus catches the wind, which disperses the seed. The plant also reproduces vegetatively via its creeping stolons.
