Antennaria geyeri is distinctive because it has woody upright branches and is not stoloniferous. It lacks basal leaves at flowering and has heads that are often described as subdioecious (central flowers are often bisexual). As the only member of the Geyerae group, A. geyeri is not closely related to any other species of Antennaria; it bears strong similarities to some species of Anaphalis (R. J. Bayer 1990; Bayer et al. 1996).

Antennaria geyeri ( anglais )

fourni par wikipedia EN

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, 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]
