A.* brevistyla, Hook.i A foot or more high, pubescent and somewhat glandular-pubescent 

 above: flower small: lamina of yellowish petals little shorter than the (half inch) obtuse 

 sepals and longer than the blue spur: styles (2 lines long) much shorter than the forming 

 pubescent-follicles. — Fl. Bor.-Am. i. 24; Torr. & Gray, Fl. i. 30. A. vulgaris, Richards, 

 in Frankl. 1st Jour. ed. 1, App. 740 (reprint, p. 12). — Rocky Mountains of Brit. America, 

 Bourgeau, Macoun, northward to Bear Lake, where first collected by Dr. Richardson, and 

 southward according to Rydberg to the Black Hills of S. Dakota, L. Anderson. 



A.* saximontana, P. A. Rtdberg. Much lower, scarcely a span high : stems slender, 

 several from a scaly rootstock, quite glabrous : leaves small, twice ternate, even the upper 

 slender-petioled, smooth : flowers much as in the preceding, but carpels glabrous. — Rydberg 

 in ms. A. vulgaris, var. brevistyla. Gray, Am. Jour. Sci. ser. 2, xxxiii. 242 ; Porter & 

 Coulter, Fl. Col. 4. A. brevistgla. Coulter, Man. Rocky Mt. Reg. 10; Jones, Zoe, iv. 258. — 

 Rocky Mountains of Colorado, first collected by Parry. 



A. flavescens, Watson, a foot or two high, branching freely : flower lemon-yellow, green- 

 ish yellow, or ochroleucous, the sepals sometimes scarlet-tinted outside : lamina of the jjetals 

 obovate, shorter than the oblong or ovate acute sepals, equalling or shorter than the spur : 

 styles 3 to 6 lines long, much longer than the pubescent ovary, half the length of the full- 

 grown follicle. — Bot. King Exp. 10; Gray, Am. Jour. Sci. ser. 3, iii. 149 ;. Baker, Gard.

 Columbia, and south to Oregon and Utah.''^ 



A.* micrantha, A.Eastwood. Slender, perennial (?), densely glandular-pubescent and 

 viscid above : leaflets small, cuneate, 3-cleft, with 2-3-lobed segments ; petiolules of the 

 lateral leaflets short : flowers about 10 lines in diameter, ochroleucous: sepals 5 lines long, 

 2 lines broad: petals truncate or nearly so, with a short straight or curved spur. — Proc. 

 Cal. Acad. Sci. ser. 2, iv. 559, t. 19. — Abundant in canons of the San Juan River, S. E. 

 Utah, A. Wetherill. Description here condensed from the original characterization. A very 

 similar if not identical plant was collected in imperfect specimens in Southern Utah by 

 Siler in 1883. 



A-* ecalcarata, A. Eastwood. A slender branched perennial, U to 2 feet high with 

 foliage and habit nearly as in the preceding : root long, woody : stems several, sparingly 

 glandular-puberulent above : leaflets obovate, cuneate, cleft as in the last ; the lateral as 

 well as the terminal on slender more or less elongated petiolules : flowers white or roseate, 

 fragrant : petals and sepals subsimilar, 6 to 8 lines long ; the former merely saccate at base : 

 styles rather long. — Zoe, ii. 226, iv. 3, & Proc. Cal. Acad. Sci. ser. 2, iv. 560, t. 18; Jones, 

 Zoe, iv. 259. — Shaded cliffs, S. W. Colorado, A. Wetherill, Miss Eastwood. As yet too 

 little known and appearing rather near the preceding, of which it may well prove a nearly 

 spurless form. 



H— -t— Scape naked, one-flowered. 



A. Jonesii, Parry. Densely caespitose, soft-pubescent : tufted radical leaves an inch or two 

 high ; leaflets only 2 or 3 lines long, much congested, the partial petioles very short : scape 

 little surpassing the leaves (2 or 3 inches long in fruit) : flower blue : lamina' of petals half 

 the length of the oblong obtuse sepals and of its own spur : follicles proportionally large 

 (almost an inch long), twice the length of their styles. — Am. Nat. viii. 211 ; Coulter, Man. 

 Rocky Mt. Reg. 10. — N.W. Wyoming, alpine region. Mount Phlox, Parry; Maria Pass in 

 Montana, at 8,200 feet, Canby.^ 



* * American type, with spur straight, or the callous knob at tip merely oblique. 



1 The description of this species has been modified to exclude the following, which ai)pears wholly 

 distinct. 



2 The alpine smaller-flowered form mentioned by Dr. Watson (Bot. King E.xp, 10) is regarded as 

 distinct by Prof. M. E. Jones. It appears to approach the following species too closely to be charac- 

 terized as a separate species without more copious material of both.
