PAYSON—-NORTH AMERICAN AQUILEGIA. 155 
21. Aquilegia scopulorum Tidestrom, Amer. Mid. Nat. 1: 167. 1910. 
Aquilegia caerulea calcarea Jones, Proc. Calif. Acad. II. 5: 619. 1895. 
Aquilegia scopulorum forma calcarea Tidestrom, Amer. Mid. Nat. 1: 170. 1910. 
Cespitose alpine perennial, the stems 8 to 15 cm. long, more or less viscid-pubescent, 
especially above; basal leaves forming a dense tuft on the apices of the large caudex, 
biternate; cauline leaves mostly reduced to 1 or 2 entire or 3-lobed bracts; leaflets 
small, about 1 cm. broad, coriaceous, rounded, the base truncate; flowers solitary, 
erect, about 5 cm. long; sepals pale blue, broadly oblong, obtuse or acute, 3 to 4 cm. 
long; petals yellow or white, oblong, the apices rounded; spurs straight, 3 to 4 cm. 
long; ovaries densely pubescent; styles about 5 mm. long; follicles about 2 cm. long, 
the tips spreading. 
TYPE LOCALITY: Wasatch Peak, central Utah. 
Rance: High altitudes in Utah, Nevada, and southwestern Wyoming. 
SPECIMENS EXAMINED. 
Wyomina: Bridger Peak, Cary 635. 
Uran: Wasatch Peak, Tidestrom 1788 (type). Divide between Sevier and Beaver 
rivers, near Belknap Peak, Rydberg & Carlton 7334. Canyon above Tropic, 
Jones (type of A. caerulea calcarea). Gold Mountain, near Marysvale, Jones. 
Nevapa: Bunker Hill, Lander County, Kennedy 4181, Hitchcock 884. 
An alpine relative of A. caerulea, differing from that species by its low, one-flowered 
stems, its very small, congested, coriaceous leaflets, and its smaller, light blue and 
yellow flowers. It is extremely difficult, if at all possible, to separate the form 
calcarea from the species scopulorum. 
22. Aquilegia pubescens Coville, Contr. U. S. Nat. Herb. 4: 56. pl. 7. 1893. 
Stems 20 to 30 cm. high, glabrous below or minutely pubescent throughout; basal 
leaves from once to twice ternate; leaflets medium in size, glabrate to densely pubes- 
cent beneath, the lobes rounded; stem leaves few or none, passing into linear tri- 
partite bracts; flowers few, canary yellow thoughout, erect, 4 to 5.5 cm. long, 4.5 to 
6 cm. across; sepals linear-oblong, bluntly acute, 20 to 25 mm. long, spreading hori- 
zontally; laminz 8 to 14 mm. long, truncate or retuse at apex; spurs 35 to 40 mm. long, 
straight or spreading; styles 10 to 15 mm. long; ovaries pubescent. 
Type LOCALITY: White Chief Mine, Mineral King, Tulare County, California (Co- 
ville 1513). 
RanGE: Alpine in the Sierra Nevada of California from Tulare County to Mari- 
posa County.

This species of the high California Sierra is somewhat similar to A. chrysantha of 
the warmer and drier mountains of New Mexico and Arizona, but is distinguished 
from it by the much less dissected leaves, lower hebit of growth, and fewer, smaller 
flowers. The illustration accompanying the description of this species is excellent. 
Jepson ! says: ‘‘The typical pubescent form occurs south of Kings Canyon; the speci- 
mens received by us from north of Kings Canyon are glabrous or nearly so.”’
