GREEN 



GREEN-FLOWERED MILKWEED. 



Asclepias verticillata. Milkweed Family. 



Stem. Slender; very leafy to the summit. Leaves. Very narrow ; from 

 three to six in a whorl. Flowers. Greenish- white ; in small clusters at the 

 summit and along the sides of the stem. Fruit. Two erect pods, one often 

 stunted. 



This species is one commonly found on dry uplands, espe- 

 cially southward, with flowers resembling in structure those of 

 the other milkweeds. 



BLUE COHOSH. 



Caulophyllum thalietroides. Barberry Family. 



Stems. One to two and a half feet high. Leaf. Large; divided into 

 many-lobed leaflets ; often a smaller one at the base of the flower-cluster. 

 Flowers. Yellowish-green or purplish ; clustered at the summit of the 

 stem ; appearing while the leaf is still small. Calyx. Of six sepals ; with 

 three or four small bractlets at base. Corolla. Of six thick, somewhat 

 kidney-shaped or hooded petals, with short claws. Stamens. Six. Pistil. 

 One. Fruit. Bluish; berry-like. 



In the deep rich woods of early spring, especially somewhat 

 westward, may be found the smooth, purplish stem, divided 

 leaves, and clustered green or purplish flowers of the blue cohosh. 

 The generic name is from two Greek words signifying stem and 

 leafy "the stems seeming to form a stalk for the great leaf."

EARLY MEADOW RUE. 



Thalictrum dioicum. Crowfoot Family. 



One to two feet high. Leaves. Divided into many smooth, lobed, pale 

 drooping leaflets. Flowers. Purplish and greenish ; unisexual. Calyx. 

 Of four or five petal-like sepals. Corolla. None. Stamens. Indefinite 

 in number ; with linear yellowish anthers drooping on hair-like filaments 

 (stamens and pistils occurring on different plants). Pistils. Four to four- 

 teen. 



The graceful drooping foliage of this plant is perhaps more 

 noticeable than the small flowers which appear in the rocky 

 woods in April or May.
