Index Seminum (Göttingen) 1838: 4. 1838 ,.
Herbs acaulescent; caudex branched or unbranched. Flowering-stems 9–45 cm, short to long-stipitate-glandular, viscid. Leaves: petiole usually long-stipitate-glandular, sometimes short-stipitate-glandular; blade (often purple abaxially), reniform to orbiculate, shallowly 5–7-lobed, 3–13 cm, base cordate, lobes rounded, margins crenate, apex obtuse, surfaces short or long-stipitate-glandular abaxially, short-stipitate-glandular adaxially, viscid. Inflorescences diffuse. Flowers: hypanthium radially symmetric, free to 0.3 mm, white or pink, obconic, 1.2–3.2 mm, short or moderately long-stipitate-glandular; sepals erect, green-tipped, equal, 0.5–1.3 mm, apex rounded; petals reflexed, white or pink, narrowly oblanceolate, unlobed, 1.5–3.5 mm, margins entire; stamens exserted 1.2–3.2 mm; styles exserted 1–3 mm, 1.5–4 mm, to 0.1 mm diam. Capsules ovoid, 2–5.7 mm, (minutely stipitate-glandular or glabrous), beaks divergent, not papillose. Seeds dark-brown, ovoid, 0.4–0.6 mm, smooth.

Discussion
Varieties 2 (2 in the flora).
The specific epithet, parviflora, is similar to that of another species, Heuchera parvifolia, but these two species are distinct and have different legitimate names. The varieties of H. parviflora are not sympatric. The species merits phylogenetic study. The Blackfoot Indians applied a poultice of the pounded root to sores and swellings (D. E. Moerman 1998).
