oblong to obovate, tapering to a rather long slender petiole, coarsely den- 
tate, smooth both sides: stems 3-6 inches high: flowers rather few, in a 
loose corymbose cyme: calyx free from the ovary, cleft nearly to the base, 
the narrow oblong segments obtuse or acutish, spreading in flower; petals 
oblong, obtuse, but little longer than the sepals, the claw very short 
. or obsolete; filaments filiform, as long as tlie petals: seeds obscurel

above the ground none: , stems annual, leafy; bracts at the base

4 SAXIFRAGOPSIS Small Bull. Torr Club xxiii, 19. 
“Low caulescent cespitose, sparingly glandular-pilose plants 
perennial by woody rootstocks. Stems straw-like, rather slender, 
not fleshy, sparingly leafy. Leaves alternate, membranaceous, 
the blade articulated to the petiole and not decurrent: petiole 
wiry, dilated into a scarious ribbed base. Inflorescence consist- 
ing of a terminal thyrsoid-panicle, its cymules peduncled, sub- 
tended by small bracts: pedicels usually bearing several opposite 
or nearly opposite bractlets below the flower. Calyx hemis- 
pheric, its tube ribbed, united to the ovary, its segments 5, 
unequal in size and shape, reflexed. Petals 5, inserted just be- 
low the sinuses of the calyx-tube, long-clawed, at length deflexed. 
Stamens 10, converging; filaments inserted at the base of the 
calyx-segments, dilated below into two thin wings ; anthers sagit- 
tate, 4-angled. Ovary very short when young, soon elongating, im- 
mersed in a glandular disk ; placente central. Follicles slender, 
the bodies united, the tips erect. Seeds minute, smooth, some- 
what curved.” 
S. fragarioides Small |. c. 20. Sazifraga fragarioides Greéne. Ces- 
pitose, the short, much branched woody caudex leafy at the ends: leaves 
thin, broadly cuneate to oblong, coarsely dentate above the middle, spar- 
ingly pubescent both sides, 8-14 lines long, on slender petioles as long or 
longer than the biade: flowering stems 3-10 inches high, slender, glandu- 
lar-pubescent, leafy; flowers numerous, in an elongated panicle; calyx 
hemispheric; its segments longer than the tube or at length shorter, ovate, 
ciliate, obtuse, reflexed. a line long; petals oblong-spatulate or spatulate, 
persistent, white, 44 longer than the calyx-lobes, at length reflexed : cap- 
sule cleft to the middle, the slender beaks slightly diverging. On dry 
cliffs in the Siskiyou Mountains, Oregon and adjacent California.
