cone" BOTANY. 
-A New Rises. — Among the Ribes collected in Colorado Ter- 
ritory during the past season by Prof. John Wolf, who was acting 
as botanist to Lieut. Wheeler’s Expedition, I find a form which 
appears distinct enough to have specific rank assigned it. A 
description is herewith sent. 
Riwes Worrt, sp. n. (R. sanguineum Pursh., var. variegatum 
S. Watson, King’s Report, völ. v, p. 100). Shrub, neither prickly 
nor spiny; two to four feet high; somewhat branching; young 
branches light brown, minutely glandular-pubescent, angled by 
two slight ridges, continuing down from the expanded base of the 
petiole above; branches of the previous year ashy-gray with a 
deciduous epidermis, which, on being shed, reveals a dark brown 
bark beneath. 
Leaves thickish cordate-orbicular, deeply 5-cleft, lobes’ rather 
obtuse, unequally serrate (though hardly doubly serrate). Aver- 
age of largest leaves two, to two and one-half inches in diameter, 
with sinus at base one-half an inch deep. Leaves slightly vis- 
cid; under surface pale green, with a few short glandular hairs; 
upper surface smoother and deeper green. Petioles from one 
half an inch to one and a half inches long, slightly margined by 
-a continuation of the principal veins of the blade; expanded at 
base, becoming semi-amplexicaul, and at times with the expat- 
sion strongly pectinately-ciliate and glandular-pubescent. 
Peduncles decidedly glandular-pubescent, one’ to two inches 
long, including the raceme, loosely 4 to 10-flowered. Bracts 
ovate-spatulate, obtuse, yellowish-white, verging to red occasion- 
ally, one to two lines long, and one line shorter than the pedicels, 
which are a little longer than the flowers. 
Sepals red, lanceolate, one to one and one-half lines long» 
never reflexed. ; 
Petals red, ovate-spatulate, half as long as the sepals and as 
long as the stamens. 
- Styles two, recurved, rising conically from the summit of the 
ovary, red for half their length and parted to, or below, the middle. 
Stigmas slightly capitate. ee 
Fruit when young, strongly glandular-hairy, but never prickly, 
becoming much smoother with age. Mature fruit not pulpy ? "i
