Plants forming rosettes or open mats, green, conspicuously glandular, ± resinously aromatic. Stems prostrate to erect, (0.5–)1–3(–3.5) dm. Basal leaves planar; stipules usually entire, rarely deeply 2-lobed; leaflets 3–7 per side, separate, divided ± 1/4–3/4 to midrib into 5–15 teeth or lobes not restricted to apex. Inflorescences open, flowers arranged individually. Pedicels becoming reflexed or recurved, 3–15 mm. Flowers: epicalyx bractlets linear-lanceolate to elliptic or ovate, 0.3–1.5 mm wide, entire; hypanthium interior glabrous; sepals acute; petals white, elliptic or oblong to obovate, apex obtuse to rounded or slightly emarginate; filaments white, glabrous, anthers at least slightly longer than wide; carpels 3–4 or (17–)20–50. Achenes 1.3–2.2 mm, finely reticulate or coarsely rugose.
Discussion
Species 2 (2 in the flora).
Section Parryae accommodates two localized species with open inflorescences in which the slender pedicels become reflexed to recurved at or soon after flowering. P. A. Rydberg (1908c) included both species in his group Cuneatae.
Selected References
None.
