40 Introduction to Botany. 



i. Aquilegia Canadensis, L. WILD COLUMBINE. Erect and branching, 

 from i to 2 feet high. Flowers about 2 inches long, usually scarlet and yellow, 

 nodding so that the straight spur points upward. In woods or on shaded, rocky 

 banks. 



IV. DELPHINIUM. Larkspur. 



(From the Greek name, delphinion.} 



Erect, branching annuals or perennials, with palmately lobed or 

 divided leaves, and irregular, showy, racemose, or paniculate flowers. 

 Sepals 5, petallike, the upper one prolonged backward into a spur. 

 Petals, 4, irregular, the upper pair sending spurs into the spur of 

 the sepal, the lower petals small, sometimes wanting. Carpels 1-5, 

 forming many-seeded pods in fruit. 



1. Delphinium azureum, Michx. (L., azureus, sky-blue.) Stems i to 2 feet 

 high, slender and somewhat pubescent. Flowers blue to white, about i inch long, 

 with upward-curving spur. Leaves deeply 3~5-parted, the divisions again deeply 

 cleft into linear segments. Racemes short and strict; follicles erect. In open 

 grounds. 



2. Delphinium tricorne, Michx. (L., tricornis, 3-horned.) DWARF LARK- 

 SPUR. Stout, 6 inches to 3 feet high. Leaves 5~7-parted, the divisions again 

 lobed or cleft. Racemes 4 to 7 inches long, loosely or compactly several to many- 

 flowered. Flowers i inch or more long, spur slightly curved. Follicles widely 

 spreading. In open grounds. 



V. ANEMONE. Windflower. 



(The old Greek and Latin name, from Gr. , anemos, wind.) 



Perennial herbs, with both radical and stem leaves, those of the stem 

 forming an involucre near or remote from the flower ; the radical leaves 

 variously lobed, divided, or dissected. Sepals 4-20, petallike ; petals 

 none. Fruit an achene, pointed or tailed. 



1. Anemone Caroliniana, Walt. CAROLINA ANEMONE. Simple stem from a 

 tuberous root ; becoming 4 to 10 inches high. Basal leaves usually 3-divided, the 

 divisions variously lobed or cleft. Involucre of 3 wedge-shaped divisions, which 

 are again 3-cleft. Flowers from | to ii inches broad. Sepals 6-20, linear oblong, 

 purplish or whitish. In open meadows. 



2. Anemone Pennsylvania, L. PENNSYLVANIA ANEMONE. From i to 2 feet 

 high; somewhat hairy, particularly on the under side of leaves. Basal leaves 3-5- 

 parted, and the divisions variously cleft ; long-petioled. The leaves of both primary 

 and secondary involucres sessile. Peduncle branched above the primary involucre, 

 the branches bearing 2-leaved involucres at the middle. Flowers from to i inch 

 or more broad; sepals white. Achenes merely pubescent or smooth. In low 

 grounds or in woods.
