Duration: Perennial Nativity: Native Lifeform: Subshrub General: Herbaceous perennials to low subshrubs, to 60 cm tall, stems erect, herbage densely tomentose and silvery-green, the stems arising from several caudices. Leaves: Alternate, twice pinnately dissected, lobes linear, 3-15 mm long, threadlike, the axils of the basal leaves densely tomentose, the cauline leaves 0-3. Flowers: Heads discoid, disk flowers yellow, 1-many, corollas campanulate, phyllaries 6-10 mm long, 2-5 mm wide, the margins white or yellowish, scarious, the tips acute to obtuse, heads 3-8, borne at the stem tips. Fruits: Achenes 4 angled, 5-6 mm long, desnely short-hairy, Pappus scales 12-22, generally linear-oblong. Ecology: Found on sands, clays, rocks schists, volcanic, and limestone substrates from 5,000-9,000 ft (1524-2743 m). Distribution: Arizona, California, Nevada, New Mexico, Utah; Mexico. Notes: The keys to this variety are the axils of the basal leaves densely tomentose; the cauline leaves 0-3, with the terminal lobes of basal the leaves 3-15 mm, the phyllaries somewhat smaller than the parent species at 6-10 mm, and the heads few at 3-8. Ethnobotany: A compound of the plant was used as a ceremonial emetic, a decoction of the plant was taken for blood poisoning, a poultice of the plant was applied to sores and infections, and the roots were chewed for decaying teeth. Etymology: Hymenopappus comes from Greek hymen for membrane and pappos for pappus, for the chafflike scales, while filifolius means thread like leaves, and lugens comes from the word lugere, to mourn.
