S. parvifolia Greene Pitt, iii, 116. Stems stoutish, 6-16 inches high, 

 from a small somewhat woody caudex, pubescent with coarse glandular 

 hairs : leaves ovate, obtuse, entire or slightly toothed, 6-10 lines long, on 

 winged petioles as long or longer, somewhat fleshy, glabrous : branches of 

 the panicle each cymosely 3-5-flowered ; calyx cleft to the middle into 

 deltoid erect segments; petals white, spatulate-oblong, obtuse; nearly 2 

 lines long, more than twice as long as the calyx ; filaments filiform ; an- 

 thers orbicular; mature carpels red, united to near the middle, adnate to 

 the tube of the calyx, only the beaks divergent. On damp open hillsides 

 about Grants Pass, Oregon. 



S. Oregana Howell Eryth. iii, 34. Canescently pubescent: leaves 

 and stem from a thickened fleshy caudex : leaves spatulate to lanceolate, 

 1-8 inches long, obtuse, obscurely repand-dentate, sessile or attenuate be- 

 low to a broad petiole : stem stout, t-4 feet high, leafless, branched near 

 the top, the branches subtended by linear-lanceolate mostly cuminate 

 bracts; flowers in dense cymules, sessile or nearly so; calyx adnate to the 

 base of the ovary, cleft to the middle, with short triangular obtuse or 

 acute at length reflexed segments; petals yellowish-white, 2 lines long, 

 oblong, attenuate below to a short claw; filaments subulate, half as long 

 as the petals: carpels distinct or nearly so, diverging, the short beak at 

 length bent at a right angle; seeds oblong. In marshes and about springs, 

 Washington and Oregon. 



5. ARABIDTA Tausch. 1. c. Caudex above the ground 

 scarcely any : stems annual, mostly leafless : calyx free from the 

 ovary; the sepals nearly distinct: petals with slender claws, 

 often unequal : filaments filiform : seeds longitudinally striate. 



S. Xutkama Moc. Engler Monog. Sax. 13-V Pubescent: stems and 

 leaves from the crown of a small fleshy caudex : leaves cuneate-spatulate, 

 sessile or some of the outer ones attenuate below to a broad petiole, 10-18 

 lines long, unequally ciliate, rather coarsely dentate above the middle : 

 stems 3-12 inches high, paniculately branched above, bearing numerous 

 propagula in the axils of the floral bracts; flowers numerous, in a loose 

 usually secund panicle; calyx free from the ovary, cleft to the base; sepals 

 broadly lanceolate, acute, very early reflexed, barely a line long; petals 

 white, with a yellow or red spot at the base of the blade, somewhat un- 

 equal, lanceolate, long-clawed; filaments clavate, as long as the petals; 

 carpels lance-ovate, united to above the middle, the short slender beaks 

 erect. In moist places on the highest mountains, Alaska to Oregon. 



S. reflexa Hook. Fl. i, 249, t. 85 Canescently pubescent: leaves 

 ovate, rather coriaceous, opaque, incisely serrate, attenuate into a peti- 

 ole : stem naked; panicle glabrous, compact, corvmbose; petals obovate, 

 marked with two orange spots, scarcely twice the length of the obtuse re- 

 flexed calyx-segments ; filaments dilated upward <r petaloid, often abort- 

 ive; ovary free from the calyx Northeastern Washington and Idaho to 

 the Arctic Sea shore. 



S. occidentalis Watson Proc. Am. Acad. xxiii. 264. Leaves some- 

 what fleshy, 6-18 lines long, roundish to oblong or ovate, coarsely dentate, 

 contracted below to a short petiole, tomentpse beneath with red or reddish 

 hairs, smooth above: stems 2-10 inches high, more or less pubescent and 

 glandular; flowers numerous, in a somewhat corymbose cyme: calyx free 

 from the ovary, cleft nearly or quite to the base, the oblong or ovate ob- 

 tuse segment not reflexed; petals white, oblong -obovate, obtuse, twice as 

 long as the sepals ; filaments slender-subulate about equalling the sepals; 

 carpels lanceolate, united below, the stout beaks divergent: seeds oblong, 

 apiculate at one or both ends, with a loose smooth testa. Common on 

 wet rocks, Brit. Columbia to California.
