 usually much smaller, cleft to middle or beyond, the main divisions with 2 or 3 

 round-oblong lobes; cauline leaves well-developed; pedicels to about 1 dm. long;

 sepals spreading, lanceolate to ovate-lanceolate, usually acuminate, 2-3.5 cm. 

 long, 5-10 mm. wide; petal blades oblong-obovate, usually rounded at apex, 

 spreading, 8-16 mm. long; spurs usually spreading, 4-7 cm. long, 4-6 mm. wide 

 at base, gradually narrowed to an almost filiform tube with slight apical thicken- 

 ing; stamens usually exceeding petal blades by 8-10 mm.; anthers 1.5-2 mm. long; 

 staminodia 9-12 mm. long, very little crinkled, subacuminate; follicles glandular- 

 pubescent, 2-3 cm. long, the tips spreading; styles pubescent, 12-18 mm. long: 

 seeds about 2 mm. long. 



On wet seepage banks and edge of pools and streams, sometimes on edge of 

 water, in sheltered crevasses, in Tex. rare in the mts. of the Trans-Pecos, N. M. 

 (Dona Ana, Grant, Bernalillo, Catron, Socorro and Otero cos.) and Ariz. (Apache 

 to Mohave, s. to Cochise, Santa Cruz and Pima cos.), Apr.-Aug.; from Ariz., 

 Colo., N.M. and Tex., s. to n. Mex. 



4. Aquilegia longissima Gray. Longspur columbine. 



Stems 5-12 dm. high, often forming large clumps, glabrous below and glandular- 

 pubescent above or glandular-pubescent throughout, open-branched above; basal 

 leaves triternate rather thin, light-green and glabrous to slightly pubescent above, 

 glaucous and glabrous to pubescent beneath; petioles slender, 2-3 dm. long, 

 glabrous to pubescent; primary petiolules 3-5 cm. long, the secondary petiolules 

 1-5 cm. long and the tertiary to 15 mm. long; leaflets much as in /i. chrysantha, 

 15-45 mm. long; cauline leaves well-developed; pedicels to 2 dm. long; flowers 

 erect, pale-yellow, somewhat glandular-puberulent; sepals spreading, lanceolate, 

 acuminate, 25-35 mm. long, 6-13 mm. wide; petal blades spreading almost 

 horizontally, spatulate to spatulate-obovate, 1.5-3 cm. long, rounded to emargi- 

 nate; spurs filiform, pendent, mostly 9-15 cm. long, 2-3 mm. wide at base, the 

 tips about 1.5 mm. thick; stamens 5-12 mm. longer than petal blades; anthers 

 1.5 mm. long; staminodia 12-14 mm. long, rather plane, subacuminate; follicles 

 glandular-pubescent, about 25 mm. long, with spreading tips; styles 16-26 mm. 

 long; seeds almost 2 mm. long. 



Along streams and in wet places among boulders, on ledges and in sheltered 

 crevices in canyons of Chisos Mts. in the Tex. Trans-Pecos and Ariz. (Cochise 

 and Pima cos.), June-Nov.; also n.e. Mex. 



4. Delphinium L. Larkspur
