Aerial shoots (20-)30-70(-80) cm, from caudices, rarely with very short ascending rhizomes, caudices ascending to vertical. Basal leaves (2-)5-10(-13), ternate; petiole 9-21 cm; terminal leaflet sessile, broadly rhombic to oblanceolate, (2.5-)3-5(-6) × (3-)4-10(-14) cm, base narrowly cuneate, margins crenate, or serrate and deeply incised on distal 1/2, apex narrowly acute, surfaces strigose, more so abaxially; lateral leaflets 1-2×-parted and -lobed; ultimate lobes 4-10(-13) mm wide. Inflorescences (1-)2-8-flowered cymes, sometimes appearing umbellike; peduncle villous to densely villous; involucral bracts 3-7(-9), 2(-3)-tiered (can appear 1-tiered), ternate, ±similar to basal leaves, bases distinct; terminal leaflet sessile, rhombic to oblanceolate, 2.5-6.5 × (1-)1.5-2(-2.5) cm, bases narrowly cuneate, margins serrate and incised on distal 1/3-1/2, apex narrowly acute, surfaces puberulous, more so abaxially; lateral leaflets 1(-2)×-parted or -lobed; ultimate lobes (4-)6-10(-15) mm wide. Flowers: pedicel usually appearing bractless; sepals 4-5(-6), green to whitish, oblong to elliptic or ovate, 5-12(-15) × 3-6 mm, abaxially silky, adaxially glabrous; stamens 50-75. Heads of achenes cylindric; pedicel 10-30 cm. Achenes: body ovoid, (1.8-)2-3 × 1.5-2 mm, not winged, woolly; beak usually recurved, (0.3-)0.5-1 mm, hidden by achene indument, glabrous. 2 n =16. Flowering summer (Jun-Jul). Prairies, dry, open woods, pastures, roadsides; 300-3000 m; Alta., B.C., Man., Ont., Que., Sask.; Ariz., Colo., Conn., Idaho, Ill., Ind., Iowa, Kans., Maine, Mass., Mich., Minn., Mo., Mont., Nebr., N.H., N.J., N.Mex., N.Y., N.Dak., Ohio, Pa., R.I., S.Dak., Vt., Wis., Wyo. The cymes of Anemone cylindrica may appear 1-tiered because the second tier of involucres is closely nestled among the leaves of the first tier. The cymes then resemble umbels with unusually leafy involucral bracts; they might be misinterpreted as such. Anemone cylindrica was used medicinally by Native Americans for headaches, sore eyes, and bad burns, as a psychological aid, and as a relief for tuberculosis (D. E. Moerman 1986).
From Flora of Indiana (1940) by Charles C. Deam
Infrequent throughout the lake area. It prefers a very sandy or gravelly soil and is usually found in prairie habitats along railroads and roadsides and in open woodland, usually on open, black and white oak ridges. Apparently it prefers a dry habitat, although the only place I ever saw it growing in abundance was on a gravelly bench on the north side of Wall Lake in Lagrange County, which was only a few feet above the water level. This bench was made several years ago when the water level of the lake receded. In this moist habitat the plants were common and vigorous, one of the specimens having 7 fruiting heads.
Indiana Coefficient of Conservatism: C = 7
Wetland Indicator Status: N/A
Diagnostic Traits: Plants mostly >30 cm; basal leaves deeply 5-parted; leaf-like cauline bracts petiolate, more than 3; flowers 1-several, white; perianth of 4-6 sepals; fruiting head to 1 cm thick, cylindrical, ca. 2–4 times as long as thick; achenes wooly.
Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Perennial, 30-70 cm tall; stems erect, silky pubescent; arising from a caudex. Leaves: Basal, ternately compound, 3-5 cm long, 4-10 cm wide, the leaflets broadly rhombic to oblanceolate, surfaces strigose, usually more so below, margins crenate or serrate and deeply incised towards the apex, base wedge- shaped, apex acute; petiole 9-21 cm long. Flowers: Inflorescence a raceme, pyramidal-shaped, often as long as wide at time of flowering, 25 or more flowers; flowers radial, pedicellate, with 1-2 bractlets at the base of each pedicel; sepals 3-5, orbicular, 2-4.5 mm long, whitish green, not persisting in fruit; petals 4-10, spatulate to obovate, 2-4.5 mm long, cream-colored, apex acute to obtuse; stamens numerous; pistil 1, the stigma nearly sessile; flowers May-July. Fruits: Achene, the body ovoid, 2-3 mm long, woolly, numerous, arranged in a cylindric-shaped head, 2-4 cm long. Ecology: Streambanks, rich soils, open woods; 1700-2300 m (5500- 7500 ft); Apache, Coconino and Gila counties; south- central Canada, northeastern, north-central, and southwestern U.S. Notes: Anemone multifida (cut-leaf anemone) [=A. globosa] is distinguished by the narrow ultimate lobes of the involucral bracts (1.5-3 mm wide); sepals are 5, green to yellow, blue, purple, or red; and the achene body is tomentose, woolly, or villous, and arranged in a spheric head. Ours is var. multifida, and in Arizona it occurs only on the San Francisco Peaks (Coconino County). Editor: Springer et al. 2008
Plants 3-10 dm, from a short caudex; basal and involucral lvs similar, the former several, the latter 3-10 and commonly twice as many as the mostly naked peduncles, both types petiolate, broad, deeply 3-5-parted into basally narrow and cuneate segments that are again few-toothed or cleft above the middle; peduncles mostly 2-6, 1-3 dm; sep 5(6), greenish-white, 8-12 mm long; styles crimson in life; fruiting head dense, cylindric, 2-4.5 cm, scarcely 1 cm thick; achenes densely woolly, 2 mm, the style 0.5-1 mm, subglabrous, seldom strongly spreading; 2n=16. Dry, open woods and prairies; Me. to B.C., s. to N.J., O., Mo., and Ariz. June-Aug.
