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 peUils 

 obovate, shorter than the oblong or ovate acute sepals, ecpialling or siiort<'r 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, Card.

A.* micrantha, A. Eastwood. Sleudcr, perennial (?). densely glandular-jiubescent and 

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

 lateral leaflets short: flowers about 10 lines in diameter, ochroleucous: sepals ;"} 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 Kiver, 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 

 Sikr 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: stem« several, sparinglv 

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

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

 fragrant : petals and sepals subsiiniiar, 6 to 8 lines long ; the ft)rmer merely s:ucate 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 clilTs, 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. 



-t— •*-- Scape naked, one-flowered. 



A. Jondsii, Fakuy, Densely crespitose, soft-pubescent: tufted Kulical leaves an inch or two 

 high ; leaflets only 2 or 3 lines long, much congested, the parti.al petioles very short : .scaj>e 

 little surpassing the leaves (2 or 3 inches long in fruit) : flower blue : lamina of petjils 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.

* * American type, with spnr straight, or the callous knob at tip merely obliiiue. 



1 The description of this .species has been modified to exclude the followinp. wliich .i]>iioiira wholly 

 distinct. 



2 The alpine smaller-flowered form mentioned by Dr. Watson (Bot. Kinp Exp. 10) is n>fjnrdf.l as 

 distinct by Prof. M. E. Jones. It appears to iijjproach the following species ton closely to 1k! charac- 

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