	Anemone parviflora	Anemone occidentalis
	northern anemone, small-flowered anemone, northern windflower	mountain pasqueflower, western pasqueflower
Habit	Sub-glabrous to densely hairy perennial from slender, horizontal rhizomes, the flowering stems 5-20 cm. tall.	Grayish, hairy perennial from a stout, branched, woody base, the stems 2-5 dm. tall.
Leaves	Basal leaves several, the blades cordate-reniform, 1.5-3 cm. broad, ternate, the leaflets wedge-shaped, coarsely toothed, the lateral pair deeply lobed as well; the flowering stem naked except for a whorl of 3 leaves above the midpoint, these simple but deeply tri-lobed.	Basal leaves long-petiolate, the blades large, ternate and 2-3 times pinnately compound, the ultimate segments linear, 0.5-2 mm. broad; the flowering stem naked except for a whorl of 3 leaves above the midpoint, these similar to the basal leaves but sessile.
Flowers	Flowers single: sepals usually 5, white or bluish tinged, hairy on the outer surface, 10-15 mm. long; petals none; stamens and pistils numerous.	Flowers single; sepals 5-8, oblong, broadly rounded, white or purplish-tinged, 2-3 cm. long; petals none; stamens and pistils numerous.
Fruits	Achenes densely woolly, obovate, 2-2.5 mm. long; style straight, 1.5-2 mm. long, glabrous.	Achenes with long, soft hairs, 4 mm. long; styles sinuous, 2-3.5 cm. long, silky-plumose.
