ing from the root; radical leaves on petioles an inch long, ternately divided 

 and many-cleft; segments linear, obtuse, cauline, 3-5-parted. Petals small, 

 1-2" long, spatulate, equalling or exceeding the sepals — Colorado (703, 

 876). 



Ageimonia Etjpatobia, L. — Collected by Professor Loew, but neither 

 date nor locality given. Probably from Arizona or New Mexico. 



Rosa blanda, Ait. Colorado (391) ; Utah. Var. ft (Fl. N. Am. T. & 

 Gr. 1, p. 460). — With leaflets smaller and some of them puberulent beneath ; 

 appendages to the calyx-lobes are also somewhat smaller than in the average 

 B. blanda. From the solitary specimen I have I should be inclined to con • 

 sider it a distinct species. — Willow Spring, Arizona, at an altitude of 7,195 

 feet (236). 



Rosa Aekansana, Porter (Fl. Col., p. 38). — "Stem stout, erect, leafy, 1° 

 high, glabrous and glaucous, armed with weak, deciduous, bristly prickles ; 

 leaflets 9-11, ovate and oblong-ovate, 1' or more in length, acute or 

 obtuse, glabrous, sharply serrate ; midrib and long stipules somewhat prickly 

 and minutely glandular ; flowers numerous, terminal, corymbed on pedun- 

 cles, about 1' long ; fruit globose, smooth, glaucous ; calyx-segments 

 ovate, reflexed in fruit, with terminal and sometimes lateral appendages, 

 more or less glandular and tomentose-pubescent on the margins ; petals 

 broadly obcordate or emarginate, longer than the calyx-segments ; flower 

 2' in diameter'' (Porter, I. c). This, as remarked by Professor Porter, 

 may only be an extreme form of B. blanda; to which it has been refeiTed 

 by Crepin — Twin Lakes, Colorado (390). 



Rosa feaxinifolia, Bork. — Differs from B. blanda chiefly in the greater 

 size of its leaflets and fruit; the former being sometimes 1J' long and 

 1' wide, and the latter "6-8" in diameter". The flowers are also larger 

 and the pubescence greater, though in these respects this species varies 

 widely. I am indebted to Dr. Vasey for calling my attention to the fact 

 that this (393), which I had placed under B. blanda in the Enumeration of 

 Colorado Plants (1874), is a different species. This is now placed by Mr. 

 Watson, in Index Am Bot. p. 312, under B. Nutkana, Presl. — Colorado. 



capitate, single ovule ascending from the base of the cell; radicle superior. — Glandular pilose herbs 

 with woody bases, and with short, leafy branches. Stipules adnate to the petiole. Flowers white or 

 purple. — Bentham & Hooker.
