upon slender pedicels, in a loose open panicle, nodding in fruit ; calyx con-

than the oblong obtuse accessory segments ; petals yellow, spatulate-oblong, 
shorter than the sepals ; stamens 5 ; carpels 1-5 ; receptacle flattened, very 
hirsute. — Resembling Potentilla Newlerryi^ Grray, (/. gracilis, Torr.,) but dif- 
fering in its perennial root, the small number of stamens and carpels, the 
style not at all enlarged or glandular at base, the small receptacle, and the 
achenium but slightly rugose. P. Newherryi was found on the shore of Rhett 
Lake in Northern California. This species is confined to the dry debris of 
granite rocks on mountain ridges. West Humboldt Mountains, Wright's 
Canon, Nevada, (W. AV. Bailey ;) 7,000 feet altitude ; September. The 
typical form has the leaflets toothed but not parted, and but 1-3 car- 
pels. (346.) 
Var. SETOSA. Leaflets deeply lobed or parted, the segments setose at 
the tip ; carpels 5. East Humboldt Mountains, Nevada, (Fremont's Pass ;)

or ascending, 6'-l° long, and with the leaves very glabrous and glaucous ; 
leaflets (often imbricated on the younger leaves) ternate, the segments 1-3"

slender elongated pedicels somewhat pubescent; accessory lobes narrow- 
subulate, shorter than the lanceolate true ones ; petals 2" long, white, un- 
guiculate, orbicular, emarginate, longer than the sepals ; stamens 20, (some-

ones inserted lower upon the broadly turbinate calyx-tube ; anthers not mu- 
cronulate ; carpels 5-8. — Near /. Pidceringii, Torr. Found in wet clayey 
subalkine soils in Monitor, Diamond and Ruby Valleys, Nevada ; 6,000 feet 
altitude; July. (348.) 
Rosa blanda. Ait. From Vermont to Pennsylvania and Wisconsin, 
west to the Rocky Mountains, and north to the Arctic Circle ; California, and 
in the Rocky Mountains of Colorado and New Mexico. Frequent on 
stream banks in the mountain ranges through Nf'vada, and in tlie Walisatch ; 
4,500-8,000 feet altitude ; May-September. Usually 4-6^ high and grow-
