About Antennaria umbrinella Rydb.
Antennaria umbrinella Rydb. is a North American species of flowering plant in the family Asteraceae, commonly known as umber pussytoes and brown pussytoes. It is native to southwestern Canada, specifically Saskatchewan, Alberta, and British Columbia, and the western United States, ranging south as far as Colorado, Coconino County in Arizona, and Tulare County in California. It grows in a wide variety of habitats across a range of elevations, from lowland sagebrush steppe to subalpine meadows.
Antennaria umbrinella is a perennial herb. It grows erect stems that reach a maximum height of around 16 centimeters, growing from a woody base with spreading stolons. Its woody base is covered in woolly leaves, each 1 to 2 centimeters long and shaped between lance-shaped and spoon-shaped. Each inflorescence holds several flower heads, with fuzzy phyllaries that range in color from whitish to brown. This plant is dioecious, meaning male and female plants produce different flower types within their heads. The fruit is an achene with a hard body 2 millimeters long, and a long pappus of hairs that can grow up to 5 millimeters long.
