Plants green, ± tufted, often forming hanging clumps, sometimes rosetted. Stems pendent or prostrate to ascending, 0.5–2(–2.5) dm. Basal leaves planar, 3–12(–18) cm; sheathing base not or sparsely strigose abaxially; petiole 1–8 cm; lateral leaflets 2–6(–10) per side, separate to slightly overlapping distally, ovate or obovate to flabellate, 4–15(–25) mm, incised 1/4–3/4 to base into 3–11(–15) ovate to oblanceolate teeth or lobes, apex not setose, surfaces ± sparsely short-pilose or hirsute, ± glandular; terminal leaflets ± distinct. Cauline leaves 1–2; blade reduced. Inflorescences (1–)5–40-flowered, open, (1–)1.5–8(–10) cm diam. Pedicels 2–15(–30) mm. Flowers 4–10 mm diam.; epicalyx bractlets 5, narrowly lanceolate to ovate, 0.8–2.5 mm; hypanthium patelliform, 0.5–2 × 2–4 mm; sepals (1.2–)1.5–4 mm, acute; petals white or pale yellow, oblanceolate to narrowly spatulate, 1.5–2.5 mm; stamens 5, filaments 0.5–1.1 mm, anthers yellow, sometimes with reddish margins, oblong, 0.4–0.7 mm; carpels (1–)3–8, styles 0.9–1.8 mm. Achenes greenish white to light tan, 1.5–2 mm, smooth or rugose, ± carunculate.
Distribution
Calif., Idaho, Nev., Oreg.
Discussion
Varieties 2 (2 in the flora).
The two varieties accepted here were not recognized by D. D. Keck (1938), who instead treated Ivesia setosa as a variety of I. baileyi. Field investigations confirm that the three entities are reasonably distinct morphologically, with intergradation where their otherwise distinct ranges overlap in central Nevada.
Selected References
None.
