Rosa feaxinifolia, Bork. Resembling the last ; flowers large, 3' in 

 diameter, and fruit also much larger, 6-8" in diameter ; rather more pubes- 

 cent and glandular; 2-3° high, growing solitary on dry ridges. — The more 

 usual form in Utah ; not seen in Nevada. Common from Washington Territory 

 to Northern California; "Wyoming Territory, (Fremont.) (350.) 



Pybus sambucifolia, Ch. & Schl. From the northern frontier of the 

 United States to latitude 55-60° and west to the Pacific ; Cascade Mountains, 

 Washington Territory; Rocky Mountains of Colorado, (Vasey.) Found in 

 the East Humboldt Mountains, Nevada, (rare,) and in the Wahsatch and 

 Uintas ; 7-8,000 feet altitude ; June-September. (351.) 



Ceat^gus eivulaeis, Nutt. (?) Leaves obovate, subrhomboidal or 

 lanceolate, cuneate at base and attenuate into a slender petiole, acuminate, 

 unequally serrate, sometimes slightly lobed, slightly pubescent above vvdth 

 the petiole, at length coriaceous and shining ; corymb glabrous or somewhat 

 pubescent, 6-12-flowered ; calyx-segments long-acuminate, subglandular, as 

 also the slender pedicels; petals rather large, 2-3" in diameter; styles 

 3-5 ; fruit large, 4-6" in diameter, dull purple with whitish dots, juicy and 

 edible. — A shrub 8-12° high, with reddish branches and few short stout 

 thorns. There is an uncertainty in the determination of these specimens ; 

 they certainly do not agree with Nuttall's description in the characters of the 

 calyx, and the leaves are rarely obtuse as in his scant specimen in Herb. 

 Torrey ; nor yet do they accord with Var. Douglasii, T. & Gr., of C. sanguinea, 

 Pall., (which had been before referred to both punctata and glandulosa, and 

 made by Lindley a distinct species, C. Douglasii,) which has broadly ovate 

 leaves, doubly serrate and usually lobed, and smaller fruit. Banks of streams, 

 Oregon. Found in the Humboldt Valley at the foot of the Clover Mountains, 

 Nevada, and in the Wahsatch, Utah ; 5,500 feet altitude ; flowering in May, 

 fruit ripe in September. (352.) 



Amelanchiee Canadensis, T. & a., Var. alnifolia, T. & G. In the 

 Western States and from the Upper Missouri to Washington Territory and 

 California, Arizona and New Mexico. Abundant in all the higher ranges of 

 Nevada and Utah, and giving their name to the " Toyabe" Mountains; 5- 

 10,000 feet altitude ; in flower, May-July ; fruit ripe in August. (353.)
