Gleaming lady’s mantle

Plants medium-sized, dark green, often somewhat sericeous (abaxial surface of leaves), sometimes reddish brown, especially on exposed distal part of stems and inflorescences, ˂to 50 cm˃. Stems usually densely spreading- to slightly ascending-hairy, usually glabrous in distal 1/2. Leaves: stipules translucent, strongly wine red-tinged proximally, ˂lobes pale green, sometimes suffused wine red; petiole densely spreading- or slightly ascending-hairy (especially in distal 1/3)˃; blade usually reniform to orbiculate, 7–9-lobed, margins flat, sometimes slightly undulate, basal sinuses relatively wide or narrow, ˂basal lobes not overlapping˃, middle lobes rounded, as long as to longer than their half-widths, to as long as wide and with straight sides; incisions usually absent or relatively short; teeth usually slightly connivent, almost symmetric to ± asymmetric, apex acute, abaxial surface with nerves hairy throughout, internerve regions uniformly or irregularly hairy, adaxial densely appressed-hairy throughout. Inflorescences: primary branches often sparsely, sometimes densely, ascending-hairy; ˂peduncles glabrous or hairy˃. Pedicels glabrous or some of the proximal hairy. Flowers ˂dark green, often becoming reddish˃; epicalyx bractlet lengths 0.5+ times sepals (narrower); hypanthium ˂attenuate at base˃, usually glabrous, rarely sparsely hairy (in proximal flowers). Achenes not exserted.

Flowering late May–Sep. Meadows, moist sand; 0–400 m; introduced; Nfld. and Labr. (Nfld.), N.S., Que.; Maine, N.Y.; Europe.

Alchemilla micans has been widely known as A. gracilis Opiz; the type of that name is referable to A. monticola, a species that the original description also fits better.
