PAYSON—NORTH AMERICAN AQUILEGIA. 149 
14, Aquilegia rubicunda Tidestrom, Amer. Mid. Nat. 1: 168. 1910. 
More or less viscid-puberulent throughout, the stems few from a branched caudex, 
the crowns densely clothed with the petiole bases of old leaves; basal leaves mostly 
biternate though often approaching the triternate condition; leaflets rather small, 
narrow, mostly cuneate at base, the lobes rounded; stem leaves wanting; flowers 
about 3 cm. long, scarcely 2 cm. across, nodding; sepals oval, acute, pinkish, 1 cm. 
long or more, exceeding the lamin by 6 or 7 mm.; lamine light yellow, slightly 
spatulate, 5 mm. long or more; spurs pale red, slender, mostly less than 2 cm. long; 
stamens twice as long as the petals; ovaries glabrous. 
Known only from the type specimen, collected by Mr. I. Tidestrom along ‘‘ Link 
Trail,’? near Emery, Manti National Forest, Utah. 
Other collections are necessary to establish this species with certainty, but on the 
whole its characters seem fairly good. It is closely related to A. elegantula and if 
reduced to subspecific rank should be placed under that species. It differs from 
elegantula in the viscid character of the pubescence, the somewhat more dissected 
leaves, the narrow segments of the leaflets, and the lighter colored flowers with longer 
sepals and more slender spurs.

Aquilegia canadensis L. err. det, Coulter, Man. Rocky Mount. 10. 1885. 
Stems slender, usually not more than 30 cm. high, mostly glabrous; basal leaves 
biternate, the stem leaves few, the leaflets small, glabrous, glaucous beneath; flowers 
3 to 3.5 cm, long, 1.2 to 1.8 cm. across, nodding; sepals entirely red or with yellowish 
or greenish tips, ovate-oblong, erect, 10 mm. long, exceeding the lamine by only 
1 to 3 mm.; lamine yellow, about 8 mm. long; spurs scarlet, straight, somewhat 
inflated above and abruptly narrowed about 5 mm, from the apex, 20 mm. long; 
styles 12 to 15 mm. long; ovaries pubescent; follicles 5, 1.5 to 1.8 cm, long, the tips 
erect or spreading. 
Type LocaLity: Near Mancos, Colorado. 
RanaeE: In the mountains of southwestern Colorado, adjacent Utah, northern 
New Mexico, and probably Arizona, at elevations between 2,250 and 3,300 meters.

This beautiful species of the Transition and Canadian zones of the southern Rocky 
Mountains is one of the smallest-flowered and one of the daintiest of American Aqui- 
legias. Though evidently most nearly related to A. canadensis of the eastern hills, 
it is easily distinguished from that species by its smaller, more graceful habit of growth
