' RIBES ARIDUM. Near R. amictum,the stems much stouter, 
rigid and flexuous, with puberulent bark, the nodes bearing 
short very stout recurved triple spines: leaves small, ca- 
nescently hirtellous on both faces: peduncles 2-flowered ; 
calyx-tube funnelform, the lobes oblong, the whole calyx 
hoary-tomentulose, dark-red withiu: fruits small, armed 
with short and stout (slender-conical) spines, in maturity 
bursting on oue side and ejecting the pulpy mass of the 
seeds, the pericarps persisting during the succeeding winter. 
A remarkable species, discovered among the arid foothills 
of the Californian Sierra near Caliente, Kern County, in 1893, 
by Mr. N. C. Wilson. The specimens are scarcely yet in 
flower, having been collected in January, but show buds 
near the time of expansion, the branches being still loaded 
with the dry pericarps of the preceding year. The charac- 
ters of the branches, spines and foliage alone, would abun- 
dantly distinguish the species from R. amictum to which I 
at the time too hastily referred the specimens. 
v RIBES CRUENTUM. Shrub of the size and habit of R. 
amictum, but wholly glabrous, leaves with their lobes less 
-erenate; flowers larger, the whole calyx with its almost 
cylindrie tube and long spreading segments deep crimson : 
petals white or pink, not strongly involute, laciniate-dentate 
across the obtuse apex: ovary and berry strongly aculeate. 
Species common in the Californian Coast Range, from 
Sonoma Co. northward into southern Oregon. Some spec- 
imens of it were present when R. amictum was first described, 
and from these the term “glabrate” found place in the 
diagnosis, the specimens cited from Hoopa Valley being of 
the present species, not the true R. amictum. This last,
