1. A. quinquefolia, L. (Fig. 1, pl. 45.) Winp Fiowrer. (A. nemo- 
rosa, Michx.). Small, delicate plant with the leaf stems about as high 
as the leaves, Flowering stem 4 to 9 in. high. Leaves divided into 5 
leaflets, the terminal one being on an independent foot-stalk, the two 
lateral ones on each side having a common foot-stalk. Borders of all 
the leaves deeply notched. The flowering stem bears a whorl of 3 leaves 
an inch or two below the solitary flower. The basal leaves appear later 
than the flower stem and leaves. Flower about 1 in. broad, white or, on 
the outside, somewhat purplish. In woods of our area. April-June. 
2. A. trifolia, L. Mountain ANEMONE. Resembles No. 1, but is 
usually larger and stouter and the lower leaves are divided into 3 leaflets 
which are broad lance-shaped. Southern Penna., and southward. May. 
3. A. canadensis, L. (Fig. 2, pl. 45.) CanapA ANEMONE. Plant 
1 to 2 ft. high. Leaflets pale beneath, breadth of most of them greater 
two or more branches which bear each a leaf whorl about which there 
may spring one or more stems each bearing a flower. Leaves 3-parted by 
sinuses extending half way or more toward the base. Borders notched. 
Basal leaves on long foot-stalks. Pistils 12 to 20. Low grounds. Com- 
mon. May-June. 
4. A. multifida, Poir. (Fig. 4, pl. 45.) CurT-LEAvED ANEMONE. (A.

high. Leaves from the base on long foot-stalks. Foot-stalks of the 
whorl leaves short. Leaves cut into many linear segments. Flower of 5 
to 9 reddish or greenish-red sepals. In the northern part of our region; 
rare. June. 
5. A. virginiana, L. (Fig. 3, pl. 45.) Tarn ANEMONE. Flowering 
stem 2 to 3 ft. high. Whole plant hairy. Foot-stalks of the leaves of 
the whorl nearly as long as the leaves themselves. Leaves 3-lobed, the 
divisions of the whorl leaves less deep than those of the basal ones. 
Breadth greater than length. Sepals generally 5, white or greenish- 
white. The fruit head elongated but less cylindric than the next species. 
Shady places. Common. June-Aug. 
6. A. cylindrica, A. Gray. (Fig. 5, pl. 45.) Lona-Leavep ANEMONE. 
Flowering stem 1 to 2 ft. high. Whole plant covered with silky hairs. 
Leaves more deeply divided than in the last species. Flowers similar to 
the last. Fruit head cylindric, often an inch or more long. Open places, 
common. June-Aug. 
7. A. riparia, Fernald. Resembles A. cylindrica but is less downy, 
with thinner leaves, those of the flower stem forming the involucre, lance-
