Rocky Mountain Flora 147 



vided into about 5 divisions, finely and sparingly puberulent when 

 young, dark green ; petioles 4—5 cm. long ; divisions of the blades 

 1.5-2 cm. long, cuneate-obovate in outline, divided half-way into 

 oblong mucronate lobes : inflorescence short and few-flowered ; 

 pedicels ascending, i cm. or less long, viscid ; bractlets minute : 

 sepals dark blue, oblong, obtuse or the upper acute, viscid-puber- 

 ulent ; spur 8—9 mm. long: upper petals blue and yellowish, 2- 

 toothed at the apex ; lateral petals 2-cleft ; lobes lanceolate : 

 follicles not seen. 



This is not closely related to any of the American species. It 

 has the cespitose habit of D. glaiiccscens, but is a much smaller 

 plant. It grows among rocks at an altitude of 3300 m. or more.

Delphinium multiflorum 



A tall perennial with a woody caudex ; stem about i mm. 

 high or more, viscid above, glabrate below : leaves palmately 

 divided into 5—7 divisions, glabrous and glaucous, pubescent only 

 on the margins and veins; petioles 1-2 dm. long, slightly dilated 

 at the base ; segments obovate-cuneate in outline, 5-7 cm. long, 

 first cleft about half-way and then again cleft into lanceolate, ovate 

 or oblong acute lobes': inflorescence long and dense, often 

 branched ; bracts linear ; pedicels ascending, i — 1.5 cm. long, 

 densely viscid-pubescent : bractlets small, linear, close under the 

 calyx : sepals light blue with darker median lines or blotches 

 towards the tips, oblong-oval, obtuse or the upper acutish, finely 

 puberulent; spur thick, straight or slightly curved, 12-15 mm. 

 long, almost horizontal : petals of the same color as the sepals ; 

 the lateral ones cleft only at the apex, often wavy-toothed : follicles 

 erect, densely viscid-pubescent. 



This is nearest related to D. cneulatum A. Nelson on one hand 

 and to D. occidentale on the other. From the former it differs in 

 the pubescence, which in D. cucidatuui is strigose, in D. iniilti- 

 floruin viscid. D. occidentale has much darker flowers and more 

 acute sepals. D. niultifloruui grows along streams and in damp 

 meadows or open woods at an altitude of 2000-2500 m.
