Peduncles erect or nearly so, straight, slender, (1-)2-5(-7) cm, sparsely villous or glabrous. Involucres campanulate, 1-2 × 2-3 mm, villous; teeth 5, mostly erect to spreading, 1-3 mm. Flowers 1-3 mm; perianth white to rose or yellow, sometimes becoming reddish, glabrous; tepals dimorphic, those of outer whorl oblong-ovate, 2-saccate-dilated proximally, those of inner whorl linear-oblong; stamens mostly included, 1-1.5 mm; filaments mostly pilose proximally.

Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Annual, to 30 cm tall, dichotomously branching above the base, the branches ascending or spreading. Leaves: Linear-lanceolate to oblanceolate, to 20 mm long and 4 mm wide, white lanate beneath, pubescent above, somewhat revolute, sessile or narrowed to a short petiole. Flowers: No corolla, the calyx white or pink, the broad, oval, outer lobes with a green midvein, borne in involucres, solitary or on long peduncles arising from the leaf axils, the involucres campanulate, usually more than 10-flowered, stamens 9, styles 3. Fruits: Achenes angled but not winged Ecology: Found in pine woods from 4,500-7,000 ft (1372-2134 m); flowering July-October. Notes: The keys to this species are the white-lanate undersides of the leaves, the leaves linear-lanceolate or linear-oblanceolate, revolute, and the ovate outer perianth lobes. Ethnobotany: Unknown Etymology: Eriogonum is from Greek erion, wool and phyllon, leaf, while pharnaceoides is uncertain. Synonyms: None Editor: LCrumbacher, 2011
