PAYSON—-NORTH AMERICAN AQUILEGIA. 145 
7. Aquilegia shockleyi Eastw. Bull. Torrey Club 32: 193. 1905. 
Stems branching, glabrous on the lower part, viscid-pubescent on the upper, clothed 
at base with the persistent bleached remains of the leaves, about 40 cm. high; basal 
leaves triternate, varying in length from much shorter than the stem, scarcely reach- 
ing the lowest branches, to 50 cm. high with long, stout petioles; leaflets pale 
green, glabrous, but under the lens densely covered with shining yellow glands, 
cuneate in outline, 3-lobed with cuneate, deeply crenate lobes, the middle leaflet 
broad, petioluled, the lateral generally unequal-sided, often sessile; cauline leaves 
with short sheathing petioles, less compound, the upper ones 3-cleft, with nar- 
rowly linear, acute divisions; bracts simple, linear-acuminate; sepals lanceolate, 
obtuse, somewhat undulate, especially toward the short curved claw; blade 17 mm. 
long, 6 mm. broad; claw somewhat more than 2 mm. long; laminz truncate or rounded 
at apex, 5 to 6 mm. long, 4 mm. wide; spurs about 3 cm. long, attenuate for 6 mm. 
about the globular honey gland, then gradually dilating to the throat; ovaries pubes- 
cent; follicles spreading but little; seeds reddish brown. 
Known only from the type collection, Shockley 504, from Soda Spring Canyon, 
Esmeralda County, western Nevada. 
Aquilegia shockleyi is rather doubtfully distinct specifically from A. formosa. It 
is another of those perplexing forms into which A. formosa is seen to merge. Its 
characteristic peculiarities are the long spurs and the triternate leaves. 
8. Aquilegia wawawensis sp. nov. PiatE 10. 
Stems erect, slender, glabrous or puberulent, about 40 cm. high; basal leaves on 
slender, rather weak petioles 15 to 20 cm. long, biternate or triternate; petiolules 
filiform, puberulent, rather short; leaflets small, very thin, glabrous, glaucous beneath, 
3-lobed, each lobe rather sharply incised; cauline leaves few, similar; bracts of 1 to 3 
incised leaflets clothing the upper portions of the stem; flowers on short, slender 
pedicels, 3 to 3.5 cm. long and about as wide, nodding; sepals pale red, ovate- 
elliptic, obtuse, reflexed, about 2 cm. long; laminz yellow, rounded, about 3 mm. 
long; spurs pale red, very slender, straight or slightly hooked at apex, about 2 cm. 
long, the nectary small; styles 10 mm. long; ovaries puberulent. 
Type in the U. 8S. National Herbarium, no. 763898, collected at Wawawai, Wash- 
ington, on the south bank of the Snake River, ‘‘in dripping water,’’ May 26, 1906, 
by Rex Hunt (no. 203). 
Aquilegia wawawensis is similar in many ways to A. formosa, and though no doubt 
an offshoot from that species, is apparently deserving of specific rank. It is of unusual 
appearance because of the almost membranous texture of the leaflets, the peculiar 
bracts which clothe the upper parts of the stem, and the small, pale red flowers with 
very slender spurs. 
EXPLANATION OF PLATE 10.—Aquilegia wawawensis Payson. From the type specimen. About 
one-half natural size. 
9. Aquilegia tracyi Jepson, Fl. West. Mid. Calif. ed. 2. 165. 1911. PLATE 11, 
Puberulent and viscid throughout; stems 50 to 100 cm. high; basal leaves triter- 
nate; leaflets variable in shape, rather large, glabrous beneath, the lobes often acute 
or pointed; flowers 4 to 6 cm. long, 3.5 to 4.5 cm. across, nodding; sepals red, reflexed, 
acute, 20 to 25 mm. long; laminz obsolete; spurs red, stout, spreading, 2.5 to 3.5 cm. 
long, the throat very broad, its orifice cut backward obliquely and not horizontally, 
abruptly contracted near apex; styles 13 to 18 mm. long; ovaries pubescent; follicles 
about 2 mm. long, the tips spreading.

counties.
