Rush Pussytoes

Antennaria luzuloides Torr. & A. Gray

Comments

provided by eFloras
Some authors have recognized Antennaria microcephala (= A. luzuloides subsp. aberrans) as a distinct species. Given the intergradation between A. luzuloides in the strict sense and A. microcephala in the strict sense, one species with two subspecies seems justified. Perhaps the most significant difference between the subspecies is ecologic. Antennaria luzuloides is a member of the Argenteae group.

Antennaria luzuloides

provided by wikipedia EN

Antennaria luzuloides is a North American species of flowering plant in the family Asteraceae known by the common name rush pussytoes.[2] The species is native to western Canada (Alberta, British Columbia) and the western United States (Oregon, Washington, northern California, Idaho, Montana, Nevada, Utah, Colorado, Wyoming, and a few isolated populations in South Dakota).[3][4]

Antennaria luzuloides is a perennial herb growing greenish white or gray erect stems from a small woody caudex. It reaches a maximum height of about 25 centimeters. There is a basal patch of grayish woolly leaves each a few centimeters long and linear in shape to somewhat spoon-shaped. The inflorescence holds up to 30 rounded flower heads each less than a centimeter wide. The head is lined with narrow, pointed phyllaries. The species is dioecious, with male and female plants producing different flower types. The fruit is an achene up to about 6 millimeters in length including a long, soft pappus.[2]
