Acaulescent annual producing a cluster of small fusiform roots from a slender caudex, 

 glandular-pubescent throughout. Leaves crowded about the base of the scape, linear-elliptic to 

 oblong-oblanceolate, 0.5-3 cm. long, entire, very rarely shallowly toothed toward the acute 

 apex; scapes one to several, 0.5-2 dm. tall, becoming more or less divaricately branched above; 

 pedicels filiform, usually all but the terminal soon deflexed and bearing conspicuous bulblets; 

 terminal flower as well as the bulblets subtended by minute greenish or reddish bracts 1-3 mm. 

 long; sepals ovate, 1.5-2.5 mm. long, usually reflexed; petals elliptic to ovate-oblong, 2-3 mm. 

 long, white with 2 yellowish spots at the base, almost regular to more usually unequal, the 

 3 larger abruptly clawed ; capsule 3-4 mm. long, the extremely short styles divergent. 



In moist gravelly soil. Boreal Zones; Sierra Nevada from Plumas County to Tulare County, California. Type 

 locality: Ebbett's Pass, California. July-Aug.

Acaulescent from a perennial fibrous-rooted caudex often beset with numerous bulblets. 

 Leaves 1-5 cm. long, the blades ovate to spatulate or oblong, undulate, sinuate-crenate to shal- 

 lowly crenulate or crenate-dentate, green above, often purplish beneath, cuneately or more_ ab- 

 ruptly narrowed into the often broadly winged petioles; scapes solitary, less usually paired, 

 slender, purplish to reddish, only sparingly and very inconspicuously glandular-pubescent below, 

 5-18 cm. tall ; cymules mainly or wholly aggregated into a terminal head- or umbel-like cluster, 

 the peduncles and pedicels very short, non-glandular, glabrous ; sepals ovate or often very much 

 broader, 1-1.5 mm. long; petals obovate to oblong-obovate, 1.5-2 mm. long, longer than the 

 sepals, narrowed to a claw-like base; filaments subulate; capsule 2.5-4 mm. long, purple. 



Wet or recently moist gravelly soil, Boreal Zones chieflv; mountains of northern Trinity County eastward 

 to Mount Shasta and southward in the Sierra Nevada to Tulare County, California. Also in the mountains of 

 adjacent Oregon and Nevada. Type locality: "Near Donner Lake," California. May- Aug.

Acaulescent perennial herb from a relatively stoutish, fibrous-rooted caudex. Leaves thin- 

 nish, 2-10 cm. long, the blades ovate to oblong or elliptic, shallowly undulate and denticulate or 

 remotely serrate with gland-tipped teeth, glabrous or only sparingly pubescent, gradually to 

 abruptly narrowed into petioles usually shorter than the blades; scapes often stout, 1-3.5 dm. 

 tall, rather copiously and evenly glandular-pubescent ; cymules permanently contracted, forming 

 a narrowly pyramidal or cylindric cyme, the lower peduncles becoming somewhat lengthened; 

 hypanthium often enclosed in a filmy envelope (possibly of teratological origin) ; sepals triangu- 

 lar-oblong, 2-2.5 mm. long; petals oblong to cuneate, shorter than, though sometimes equaling 

 the sepals, often greenish, sometimes lacking; filaments subulate, about as long as the petals; 

 capsule stoutish, 4.5 mm. high, merely the tips divergent. 



Moist hillsides and rocky slopes, Arid Transition Zone; from the eastern base of the Cascade Mountains of 

 Washington eastward to Montana and south to adjacent Oregon. Type locality: Pullman, Washington. April- 

 June. Erroneously referred to 5. nidifica by St. John, Flora of Southeastern Washington. 



Saxifraga plantaginea Small, Bull. Torrey Club 23: 366. 1896. Acaulescent from a thick caudex; leaves 

 drving leatherv, oval to rhombic, varying to oblong, often rufous-hairy beneath; hypanthium often enclosed in a 

 filmy envelope'; petals broadly obovate, usuallv shorter than the sepals. Mountains of eastern Washington and 

 adjacent Idaho. Type locality: "Spokane," Washington. 



19. Saxifraga nidifica Greene. Peak Saxifrage. Fig. 2254. 



Saxifraga nidifica Greene, Erythea 1 : 222. 1893. 



Acaulescent, often diminutive perennial from a caudex densely beset with bulblet-like off- 

 shoots. Leaves broadly ovate to narrowly elliptic, 1^1 cm. long, sparingly repand-denticulate to 

 almost entire, glabrous or very rarely glandular-hirsutulous, pale green or purplish-tinged, more 

 or less abruptly narrowed to slightly winged petioles often longer than the blades ; scapes slender, 

 1-3 dm. tall, glandular-pubescent quite or almost to the ultimate pedicels ; bracts oblong-linear, 

 much shorter than the peduncles; hypanthium glabrous; sepals ovatish to oblong, obtuse, 1.5- 

 1.8 mm. long, glabrous, ultimately reflexed; petals white, oval -orbicular to more usually spatu- 

 late-elliptic, mostly sessile, varying from slightly shorter than to slightly longer than the sepals ; 

 filaments short, narrowly triangular. 



Meadows and bogs, mostly Boreal Zones; Sierra Nevada of California, from Tulare County northward to 

 Siskiyou County, westward to Trinity and Humboldt Counties, and northeastward to the mountains of eastern 

 Oregon. Type locality: above Donner Lake, Placer County, California. June- Aug.
