PAYSON—NORTH AMERICAN AQUILEGIA. 153 
SPECIMENS EXAMINED. 
Arizona: Pinus ponderosa area, Warm Spring Canyon, Buckskin Mountains, Tide- 
strom 2329 (type). 
Uran: Sevier National Forest. Mount Ibapah, Jones. 
This plant is to be distinguished from the subspecies albiflora by the very long, 
slender spurs. The length of the spurs in this subspecies, though otherwise unusual 
in the species, can scarcely be considered of specific value, since the spurs of the typi- 
cal form occasionally exhibit an equal length. I have at hand a specimen of A. caer- 
ulea from the La Sal Mountains of Utah (Jones, June 13, 1913), with dark blue sepals 
and with spurs quite as long as those of this subspecies. A specimen from the Lara- 
mie Hills, Albany County, Wyoming (Nelson 249, June 22, 1894), also has spurs 
nearly 7 cm. in length. The altitudes at which this form grows are somewhat lower 
than those at which the species is found (about 2,100 meters). 
18c. Aquilegia caerulea alpina A. Nels. First Rep. Fl. Wyo. 78. 1896. 
Aquilegia oreophila Rydb. Bull. Torrey Club 29: 146. 1902. 
Stems 40 to 60 cm. high; lower leaves biternate, the leaflets large, thin; flowers 
few, 3 to 5 cm. long, erect; sepals pale blue; petals yellow or ochroleucous. 
Type LocaLity: Union Peak, Wind River Mountains, Wyoming. 
Rance: Northwestern Wyoming, at high elevations. 
SPECIMENS EXAMINED. 
YELLOWSTONE NATIONAL Park: Snake River, A. & E. Nelson 6412. 
Wyomina: Union Peak, Nelson 894. Teton Pass, Merrill & Wilcox 979. 
Differing from the species by such slight characters that it is often difficult to decide 
as to the identity of a particular specimen. The color of the flowers of this reminds 
one of the flowers of A. scopulorum, but, unlike scopulorum, it has no distinguishing 
habit of growth. 
18d. Aquilegia caerulea daileyae Eastw. Proc. Calif. Acad. III. 1: 76. 1897. 
Spurs entirely wanting; sepals and petals similar, flat, blue. 
Type from Estes Park, Colorado. These so-called ‘‘stellate”’ forms seem to occur 
occasionally in most of the species.

Aquilegia eastwoodiae Rydb. Bull. Torrey Club 29: 146. 1902. 
Aquilegia mancosana Cockerell, Torreya 11:75. 1911. - 
Stems 30 to 50 cm. high, pubescent and viscid throughout, more or less irregularly 
ribbed; basal leaves triternate, the leaflets sessile or short-petioluled, rather small 
and narrow, the lobes obtuse or acute, thick, densely pubescent and viscid beneath; 
flowers about 2 cm. across, erect (?); sepals creamy white, ovate, acute, 10 mm. long, 
4mm. broad; lamine creamy white, truncate or slightly retuse, about 7 mm. long 
‘and 5 mm. broad; spurs white, reduced to saclike outgrowths at the base of the 
petals; styles 5 to 7 mm. long; ovaries viscid-pubescent: follicles 4 or 5, about 
15 mm. long, the tips spreading. 
Type LocaLity: Johnston Canyon, Mesa Verde National Park, Colorado. 
Ranae: Known only from the type locality.
