A variable species, resembling A. cacrulea, but easily distinguished from it, although 
differing in but few constant technical characters except color. The spurs are, as 
a rule, longer and more slender, the sepals acuminate instead of acute or obtuse and 
narrower, the basal leaves more divided (triternate instead of biternate), and the 
plant taller and more floriferous. Its range, too, is farther south and the stations at 
which it is found at lower altitudes. 
24. Aquilegia chaplinei Standley, sp. nov. 
Stems slender, glabrous except in the inflorescence, about 35 cm. high; basal 
leaves borne on slender petioles 7 to 10 cm. long, scarcely triternate; leaflets small, 
suborbicular or somewhat narrowed, 10 to 12 mm, long, glabrous, thickish and firm; 
flowers about 3 cm. across, 5 to 6 cm. long, mostly erect; sepals spreading, yellow or 
slightly tinged with blue, broadly lanceolate, acute or obtuse, 13 to 15 mm. long, 
equaling or but little exceeding the lamin of the petals; laminz yellow, dilated, 
truncate or rounded; spurs very slender, straight or spreading, 3.5 to 4 cm. long, the
