RANUNCULACEAE. 139 



2. AQUILEGIA L. Columbine. 



Erect branching perennial herbs with ternately de- 

 compound leaves and large showy flowers. Sepals 5, 

 regular, petaloid, deciduous. Petals concave, spurred at 

 base. Stamens numerous, the inner ones reduced to 

 stamlnodia. Carpels 5, sessile, many-ovuled, forming 

 heads of follicles in fruit. 



1. A. truncata F. & M. Glabrous or somewhat viscid-pubes- 

 cent, 6-12 dm. high; leaves large, biternate, the leaflets roundish, 

 cuneate at base, incised, the segments lobed or crenately toothed, 

 long-petioled; flowers scarlet, tinged with yellow, reflexed; sepals 

 truncate, widely spreading, shorter than the spurs; follicles 2-3 cm. 

 long, veined, beaked by the long persistent style. 



Occasional in moist shady places, mostly above 2500 feet alti- 

 tude. May-July. 



3. DELPHINIUM L. Larkspur. 



Annual, or ours perennial, erect branching herbs with 

 palmately divided leaves, and racemose or paniculate 

 showy flowers. Sepals 5, the posterior one prolonged 

 into a spur. Petals usually 4, the 2 posterior spurred. 

 Carpels few, becoming many-seeded follicles. 



Flowers not red. 



Stems hirsute, at least below. 2. D. variegatum. 



Stems glabrous or puberulent. 



Divisions of the leaves linear. 1. D. parryi. 



Divisions of the leaves round-ovate to 



cuneate. 3. D. decorum. 



Flowers red. 4. D. cardinale. 



1. D. parryi Gray. Glabrous or minutely and sparsely puberu- 

 lent; stems erect, 4-8 dm. high, from rather simple or lew-fascicled, 

 elongated roots, neither fusiform nor tuberiform; leaves 3-5-parted, 

 the divisions and few lobes linear, obtuse; raceme virgate, at length 

 rather loose; sepals mostly broadly oblong, about 10-15 mm. long, 

 equaling the spur, deep blue, sparsely and minutely puberulent or 

 glabrate; upper petals white-margined, 7-8 mm. long; follicles 

 about 15 mm. long, apparently glabrous and shining, but minutely 

 puberulent under a lens. 



Frequent in the foothills throughout our region. April-June. 



2. D. variegatum T. & G. Usually hirsute-pubescent below; 

 stems erect and rather rigid, 3-6 dm. high, from rather short and 

 closely fascicled, somewhat fusiform roots; leaves 3-5-parted, the 

 divisions and lobes broadly linear, obtuse; raceme mostly few- 

 fiowered and rather close, sepals roundish-obovate or oval, 15-20 

 mm. long, equaling or exceeding the spur, violet-blue or purple, at 

 least the spur grayish puberulent; upper petals entirely white or
