Identification Comments: | Plants herbs, erect or spreading, annual, 0.5–4 (5) dm tall, minutely viscid, yellowish-green; stems with caudex absent, the aerial flowering stems erect, solid, not fistulose, 0.2–1 dm long, minutely viscid; leaves basal, the petioles 0.5–4 cm long, floccose, the blades elliptic to broadly ovate, 0.5–3 cm long and wide, densely white-tomentose abaxially, thinly floccose to glabrate and greenish adaxially, the margins plane; inflorescences cymose, open, 3–35 cm long, 3–30 cm wide, the branches minutely viscid, the bracts 3, scalelike, 1–2 mm long and wide; peduncles erect or nearly so, straight, filiform, 0.5–1.5 cm long, viscid; involucres narrowly turbinate, 1–1.2 mm long, 0.6–0.8 mm wide, viscid, the teeth 4, erect, 0.3–0.5 mm long; flowers 1.3–1.5 mm long in early anthesis, becoming 1.5–2 mm long, the perianth pale yellow to yellow in early anthesis, becoming tinged with red, glabrous, the tepals monomorphic, oblong, the stamens included, 0.9–1.1 mm long, the filaments glabrous; achenes light to dark brown, trigonous, 0.8–1 mm long, glabrous. |
Subspecies Comments: | |
Lookalikes: | Related to Eriogonum subreniforme, may be distinguished from all related annual species by the viscid glandularness of the stems and branches. |
Phenology Comments: | Flowering Apr-Jun. |
Reproduction Comments: | |
