Alchemilla obtusa Buser; A. obtusa var. comosa Brenner; A. pseudomicans Böcher; A. vulgaris Linnaeus var. comosa (Brenner) Fernald & Wiegand

Plants medium-sized, grass green or glaucous, often becoming reddish orange when young changing to dark brownish especially on margins of leaves and flowers (young flowers are yellowish), ˂often coarse, 30–40 cm˃. Stems appressed-hairy throughout (hairs becoming looser and ± ascending distally). Leaves: stipules translucent to pale green, appearing brownish upon drying; ˂petiole thickly, usually densely appressed-hairy throughout, rarely glabrous or sparsely hairy (on spring leaves)˃; blade reniform to orbiculate, 7–9-lobed, margins undulate, basal sinuses narrow, middle lobes equal to longer than their half-widths; incisions absent; teeth: sometimes proximal sides at least slightly connivent, slightly concave near apex, slightly asymmetric, apex subobtuse to acute, abaxial surface with nerves hairy throughout, internerve regions ± hairy throughout, adaxial ˂light to grass green, sometimes glaucous, margins and folds usually turning reddish orange˃, sparsely to densely appressed-hairy throughout or only on folds. Inflorescences: primary branches densely appressed- to ascending-hairy; ˂peduncles appressed- to ascending-hairy or glabrous˃. Pedicels mostly glabrous or some of the proximal hairy. Flowers: epicalyx bractlet lengths 0.5 times to almost equal to sepals (narrower); hypanthium glabrous or sparsely appressed-hairy (on proximalmost flowers). Achenes not exserted.

Flowering late Jun–Sep. Moist herb slopes, willow scrub; 0–500 m; Greenland; Nfld. and Labr. (Labr.), Que.; Europe.

In contrast to Alchemilla wichurae, A. glomerulans occurs throughout the southern (unglaciated) portion of Greenland.
