40 Introduction to Botany. 



1. 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, delpkiition.) 



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 aziireum, 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 tricome, Michx. (L., tricornls, 3-homed.) Dwarf Lark- 

 spur. Stout, 6 inches to 3 feet high. Leaves s-7-parted, the divisions again 

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

 flowered. Flowers 1 inch or more long, spur slightly curved. Follicles widely 

 spreading. In open grounds. 



V. ANEMONE. Windflower! 

 (The old Greek and Latin name, from Gr. , anetnos^ 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, Wall. 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 15 inches broad. Sepals 6-20, linear oblong, 

 purplish or whitish. In open meadows. 



2. Anemone Pennsylvanica, 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 J to i inch 

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