 tate, smooth both sides: sterna 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

 Sternb. Annual, smooth or nearly so: stems slender, leafy, simple or 

 branched, 2-12 inches high: leave's rotund to ovate or lanceolate, con- 

 tracted below to a short petiole, 2-6 lines long, entire or « ith one or two

 cemes on long slender pedicels ; calyx campanulate, with short erect tri- 

 angular acute lobes, the tube doherent to the lower half of the ovary 

 in fruit: petals oblong, obtuse, 2-3 lines long, more than twice the

4 SAXIFRAGOPSIS Small Bull. Torr Club xxiii, 19. 



"Low caulescent csespitose, 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 hractlets 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 ju^t 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 ; placentse central. Follicles slender, 

 the bodies united, the tips erect. Seeds minute, smooth, some- 

 what curved." 



S. frag^arioides Small 1. c. 20. Saxifraga fragarioides Qreene. 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 blade: 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, }i 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.
