i. Aquilegia coccinea Small. Large Red Columbine. Tall, 3-8 dm. high, 

 sparingly pubsecent at the nodes. Leaves larger than in the next; leaflets with 3 

 main lubes, glaucous beneath, nearly orbicular in outline; sepals acute or acumi- 

 nate, 17-21 mm. long; spur, 30-33 mm. long; follicles straight, 20 mm. long, tipped 

 by a style shorter than the body. On cliffs and in rocky woods, Va. to Mo., Neb.

2. Aquilegia Canadensis L. Wild Columbine. (I. F. f. 1559.) Glabrous 

 or somewhat pubescent, 2-6 dm. high. Lower leaves slender-petioled, biternate, 

 the ultimate leaflets cuneate, obtusely lobed and toothed, pale beneath; leaves of the 

 upper part of the stem lobed or divided; flowers nodding, 3-4 cm. long, the spurs 

 12 mm. long, thickened at the end; stamens and styles long exserted; follicles 

 with spreading tips, about 16 mm. long, tipped with a filiform beak of about the 

 same length. In rocky woods, N. S. to the N. W. Terr., south to N. Car. and Kans. 

 April-July. 



Aquilegia Canadensis flavifl6ra (Tenney) Britton. Flowers yellow; foliage lighter 

 green than in the type. Mass., N. Y. and N. J. Rare. 



3. Aquilegia brevistyla Hook. Small-flowered Columbine. (I. F. f. 

 1560.) Slender, erect, sparingly pubescent, branching, 3-5 dm. high. Basal 

 leaves long-petioled, biternate, the ultimate leaflets nearly sessile, broadly obovate, 

 lobed and crenate; leaves of the stem few, nearly sessile, lobed or divided; flowers 

 small, nodding; spurs about 4 mm. long; stamens and short styles barely exserted; 

 follicles slightly spreading, 16 mm. long, pubescent. N. W. Terr, to S. Dak. and 

 Alb. June-July. 



4. Aquilegia vulgaris L. European Columbine. (I. F. f. 1561.) Stout, 

 erect, 3-6 dm. high. Basal and lower leaves petioled, 2-3-ternate, the lateral 

 divisions broadly obovate, obtuse, lobed and crenate, glaucous beneath; the upper 

 few, lobed or divided; spurs 6-8 mm. long, stout, strongly hooked; sepals spread- 

 ing; stamens and styles hardly exserted. Escaped from gardens in the Eastern and 

 Middle States, in N. S. and N. B. Adventive or nat. from Europe. May-July. 



12. DELPHl'xiUM L. (See Appendix.) 

 Erect branching herbs, with racemose or paniculate showy flowers. Leaves 

 palmately lobed or divided. Sepals 5, the posterior one prolonged . into a spur. 

 Petals 2 or 4, small, the two posterior ones spurred, the lateral, when present, small. 

 Carpels few, sessile, many-ovuled, forming follicles at maturity. [Latin, from the 

 supposed resemblance of the flowers to a dolphin.] A genus comprising some 60 

 species, natives of the north temperate zone. Besides the following, some 20 others
