190 SAXIFRAGACE A. PELTIPHYLLUM. 
SAXIFRAGA. 
etiole which is dilated and sheathing at base; cauline similar: petals 
inear, 1-2 lines long, scarcely longer than the calyx, white: carpels 
becoming 4-6 lines long:, purplish, but slightly divergent. In high moun- 
tain marshes, Alaska to Washington and the Rocky Mountains. 
2 PELTIPHYLLUM Engler Nat. Pil. iii, Abt. 2, 61. 
Coarse perennial herbs with peltate leaves and rather large 
flowers in paniculate cymes on scapes that appear before the 
leaves. Calyx flat, deeply 5-cleft, the very short tube adherent 
to the base of the ovary. Petals 5, entire, deciduous. Stamens 
10, persistent, inserted at the base of the calyx; anthers 2-celled. 
Carpels 2, distinct, becoming many-seeded follicles with pla- 
cente on the margin. Stigma capitate. Seeds angular, obconic 
with a loose testa. 
P. peltatum Engler |. c. Suzifraga peliata Torr. Rootstock large 
and creeping, 1-3 inches in diameter, branching; scapes and leaves from 
the ends of scaly branchlets: leaves centrally peltate, at length 6-18 
inches in diameter, orbicular, 9-14-lobed and sharply serrate, on stout 
petioles, 2-4 feet high: scapes rather stout, at length equalling the leaves, 
striate, more or less hispid with brownish hairs; flowers numerous, in 
rather large paniculate cymes; calyx-lobes oblong, obtuse, 2 lines long, 
much longer than the shallow tube; petals round-oval to obovate, 3-4 
lines long, white vr pinkish, tardily deciduous; filaments subulate with a 
broad flat base: mature follicles turgid, 3-4 lines long, dehiscent to the 
base. In mountoia streams, central Oregon to California. 
3 SAXIFRAGA L. Gen. n. 559. 
Herbs with alternate simple leaves, their petioles commonly 
sheathing at base, and usually rather small flowers in one to 
many-flowered cymose thyrsoid or panicled clusters, Sepals 5, 
united at base or nearly distinct, valvate in the bud. Petals 5, 
inserted on the tube of the calyx, entire. Stamens 10, inserted 
with or below the petals on the base of the calyx, or between it 
and a fleshy disk: anthers 2-celled, opening longitudinally. 
Carpels 2—beaked, rarely 3-6-beaked, as many-celled below, 
many-seeded, opening by a roundish hole between the diverging 
beaks. Seeds numerous, smooth or rugose, not winged, the 
testa mostly thin and conformed to the nucleus. 
S$ 1 Hircutus Tausch Hort. Canal. i. Caudex perennial, 
leafy: leaves flat, mostly persistent, often bristly ciliate, the 
margins not punctate nor cartilaginous: flowering stems annual, 
leafy: sepals united at the base, slightly coherent with the base 
of the ovary: cilia of the leaves not articulated. 
S. bronchialis L. Sp. 572 Stems ascending, slender, producing 
short branchlets: leaves somewhat coriaceous, narrowly lanceolate, acumi- 
nate-cuspidate, sessile with a broad base, finely ciliate, 2-3 lines long, 
crowded on the short branches: flowering stems 1-4 inches high; flowers 
solitary or few in an open corymh, on slender pedicels; sepals lanceolate, 
sub-mucronate, spreading; petals obovate-oblong, white marked with 
orange spots; capsule opening only half way .down, there diverging at 
right angles. Alaska to Mt. Adams, Washington, and the Rocky Moun- 
tains.
