118 BOTANY. 
Rises cereum, Dougl.—Widely diffused. The expedition has it from 
Colorado (6), Zuni Mountains, New Mexico (176), and Nevada. The 
specimens from the Zuni Mountains exactly resemble those collected in 
1851 by Sitgreaves’ Expedition, and identified by Dr. Torrey. 
RiBEs viscosissimumM, Pursh—Utah. 
Rises aurruM, Pursh—San Luis Valley, Colorado (10). Northern 
Nevada also. 
Rupes avrevM, Pursh, var. tenuiflorum, Torr. (Ribes tenuiflorum, Lindl.)— 
Distinguishable by having smaller flowers and fruit than awreum proper, yet 
closely shading into it—New Mexico (109). Specimens insufficient. 
Rises Worru, Rothrock (in American Naturalist, June, 1874). (RB. 
sanguineum, Pursh, var. variegatwm, 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- 
what 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 23 inches; depth of sinus at base in largest leaves 4 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 14 
inches long, margined by a continuation of the veins of the blade, expanded 
at base and becoming semi-amplexicaul, frequently strongly saseecires J 
ciliate and glandular. 
Peduncles 1 to 2 inches long, decidedly Siandulas-nuleasons, 4- to 10- 
flowered; bracts ovate-spatulate, obtuse, yellowish-white (occasionally 
verging toward red), 1 to 14 lines long and 1 line shorter than the pedicels, 
which are a little longer than the flower. 
Sepals red, lanceolate, obtuse, 14 lines long, never reflewed; 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.
