2. H. acutlloba DC. Leaves with 3 ovate and pointed lobes, or sometimes 

 5-lobed ; those of the involucre acute or acutish. (//. acuta Britton.) Woods, 

 w. Que., south w. through w. N. H. to Ga., Mo., and Minn., more abundant

Sepals few or many, petal-like. Petals none, or in no. 1 resembling abortive 

 stamens. Achenes pointed or tailed, flattened, not ribbed. Seed suspended. 

 Perennial herbs with radical leaves ; those of the stem 2 or 3 together, oppo- 

 site or whorled, and forming an involucre remote from the flower ; peduncles 

 1-flowered, solitary or umbellate. (The ancient Greek and Latin name, a cor- 

 ruption of Namdn, the Semitic name for Adonis, from whose blood the crimson- 

 flowered Anemone of the Orient is said to have sprung.) 



1. PULSATfLLA Pers. Carpels numerous in a head, with long hairy styles 

 which in fruit form feathery tails, as in Clematis ; flower large, usually 

 with some minute or indistinct gland-like abortive stamens answering to 

 petals. 



1. A. patens L., var. Wolf gang iana (Bess.) Koch. (PASQUE FLOWER.) Silky- 

 villous ; flower erect, solitary ; leaves ternately divided, the lateral divisions 

 2-parted, the middle one stalked and 3-parted ; segments of the leaves and ses- 

 sile involucre deeply cleft into narrowly linear and acute lobes ; sepals 5-7, pur- 

 plish blue to whitish (15-35 mm. long), spreading when in full anthesis. (Var. 

 Nuttalliana Gray ; Pulsatilla hirsutissima Britton.) Prairies, Wise., 111., Tex., 

 north w. and westw. March, Apr. (Eu., Siber.) 



2. ANEM6NE proper. Styles short, not plumose. Staminodia none. 

 * Achenes densely long-woolly, compressed ; involucre far below the flower.

2. A. caroliniana Walt. Stem 7-15 cm. high ; root-leaves once or twice 

 3-parted or cleft ; involucre 3-parted, its wedge-shaped divisions 3-cleft ; sepals 

 10-20, oblong-linear, purple or whitish; head of fruit ellipsoid. Dak. to 111., 

 Fla., and Tex. May. A. DECAPETALA Ard., said to reach e. Kan., is doubt- 

 fully distinct, its strongest character being the greater prevalence of simply ter- 

 nate basal leaves with crenate uncleft leaflets. 



*- H- Rootstock not tuberous ; sepals usually 5-8 ; styles filiform. 



3. A. parviflbra Michx. Stem 1-3 dm. high, from a slender rootstock, 1- 

 flowered; root-leaves 3-parted, their broadly wedge-shaped divisions crenate- 

 incised or lobed ; involucre 2-3-leaved ; sepals 5 or 6, oval, white, with bluish

 high); principal involucre 2-3-leaved, bearing one naked and one or two 2-leaved 

 peduncles ; leaves of the involucre short-petioled, similar to the root-leaves, 

 twice or thrice 3-parted and cleft, their divisions linear ; sepals (sometimes 

 numerous) obtuse, red, greenish yellow or whitish'; head of fruit spherical or 

 ovoid. (A. Hudsoniana Kichards.) Gravelly and ledgy (calcareous) shores
