Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Dwarf perennial herbs, to 8 cm tall, tomentose, not stipitate glandular, with wooly stolons; individuals staminate or pistillate, generally occurring equally in populations, however occasionally only pistillate individuals will be present. Leaves: Leaves mostly in a basal rosette, 1-nerved, obovate to spatulate, 5-9 mm wide, persistently tomentose abaxially, margins entire, caulescent leaves reduced, linear to oblanceolate, with acute apices. Flowers: Small discoid heads, staminate or pistillate, whitish, staminate corollas tubular, 5-toothed, pistillate corollas filiform, 8-10 mm or more high, involucres strongly graduated, phyllaries thin, membranaceous, distally white, pink, red, or brown, borne in corymbiform clusters in groups of 2-7 at the stem tips. Fruits: Achenes small, the pappus of the pistillate flowers of copious capillary bristles, pappus of the staminate flowers of clavellate, slightly flattened bristles. Ecology: Found in pastures, prairies, roadsides, parks, open woods, and drier coniferous forests, from 5,000-12,000 ft (1524-3658 m); flowering May-August. Distribution: This widespread species ranges from Manitoba to British Columbia, south to New Mexico and central Arizona. Notes: Pussytoes! Look for this species under Antennaria aprica. The keys to this species are the pistillate heads 8-10 mm or more high, the non-glandular inflorescence, and the abaxially tomentose leaves 5-9 m wide. Ethnobotany: This species was used in a variety of preparations to treat swellings, as a blood purifier, for the mad coyote bite, and as protection against witches, and the young leaves were used as greens. Etymology: Antennaria is from Latin antenna, because the flowers look like insect antennae, while parvifolia means small-leaved. Synonyms: Many, see Tropicos Editor: LCrumbacher 2011
