118 BOTANY. 



Rides cebeum, DongL— Widely diffused. The expedition lias it from 

 Colorado (6), Zufii .Mountains, New Mexico (17G), and Nevada. The 

 specimens from the Zufii Mountains exactly resemble those collected in 

 1851 by Sitgreaves' Expedition, and identified by Dr. Torrey. 



RlBES VISC08I88IMUM, Pursh. — Utah. 



Kibes AUBEUM, Pursh.— San Luis Valley, Colorado (10). Northern 

 Nevada also. 



Kibes aubeum, Pursh, var. tenuiflorum, Torr. (Ilibes U nuiflorum, Lindl.)— 

 Distinguishable by having- smaller flowers and fruit than annum proper, vet 

 closely shading into it.— New Mexico (109). Specimens insufficient. 



Kibes Wolfii, Kothrock (in American Naturalist, June, 1874). [R. 

 sanguineum, Pursh, var. variegalum, Watson, King's Report, vol. v, p. 

 100.) — 2 to 4 feet high. Neither prickly nor spiny. Moderately branch- 

 ing. Young branches light brown, minutely glandular-pubescent, some- 

 Avhat angular by two ridges continued from the edges of the expanded 

 bases of the petioles above. Branches of the previous year ashy-gray, 

 with a deciduous epidermis, which, on being shed, shows the bark under- 

 neath dark brown. 



Leaves cordate-orbicular, deeply 5-cleft; lobes rather obtuse, unequally 

 serrate, though hardly doubly serrate (average diameter of the largest leaves 

 2 to 2£ inches; depth of sinus at base in largest leaves \ inch), slightly 

 viscid ; under surface with a few glandular hairs, pale green; upper surface 

 smoother and deeper green; petioles in fully developed leaves from 1 to l£ 

 inches long, margined by a continuation of the veins of the blade, expanded 

 at base and becoming semi-amplexicaul, frequently strongly pectinately 

 ciliate and glandular. 



Peduncles 1 to 2 inches long, decidedly glandular-pubescent, 4- to 10- 

 flowered; bracts ovate-spatulate, obtuse, yellowish-white (occasionally 

 verging toward red), 1 to 1 £ lines long and 1 line shorter than the pedicels, 

 which are a little longer than the flower. 



Sepals red, lanceolate, obtuse, 1£ lines long, never rcjlexcd; petals red, 

 ovate-spatulate, half as long as the sepals, equalling the stamens; styles 

 two, distinctly conical from the top of the ovary, red for half their length, 

 parted to or below the middle, recurved; stigmas slightly capitate.
