Antennaria anaphaloides Rydb.

Antennaria anaphaloides is native to the northern Rocky Mountains and is characterized by whitish phyllaries, each with a black spot at the base. Some morphologic overlap occurs between A. anaphaloides and A. pulcherrima; the two occur in different habitats: A. anaphaloides grows in dry meadows and aspen forest openings; A. pulcherrima is usually found in moist willow thickets along streams (K. M. Urbanska 1983). Antennaria anaphaloides is closely related to the other members of the Pulcherrimae group (R. J. Bayer 1990; Bayer et al. 1996).

Dioecious. Plants 15–35(–50) cm. Stolons none. Basal leaves (ephemeral) 3–5-nerved, narrowly oblanceolate or narrowly elliptic, 25–150(–200) × 4–20(–25) mm, tips mucronate, faces gray-pubescent. Cauline leaves oblanceolate or linear, 10–80 mm, usually flagged. Heads 8–30(–50+) in corymbiform arrays. Involucres: staminate (4–)5–6.5 mm; pistillate 4.5–7 mm . Phyllaries (each with dark brown or blackish spot in middle) distally white or cream (sometimes suffused pink to rose). Corollas: staminate 2.5–4 mm; pistillate 3–4.5 mm. Cypselae 1–1.8 mm, glabrous; pappi: staminate 3–4.5 mm; pistillate 3.5–4.5(–5.5) mm. 2n = 28.

Antennaria anaphaloides, the pearly pussytoes, is a North American species of plants in the family Asteraceae. It is native to western Canada (British Columbia, Alberta, Saskatchewan) and the western United States (primarily the Rocky Mountains, with additional populations in the Great Basin and northeastern part of the Colorado Plateau).
