In bogs, Canada! and Northern States! to Virginia! and Ohio. May. — 

 Leaves 4-8 inches long, rather membranaceous, pale green, slightly ciliate. 

 Scape sometimes weak, about 2 feet high, but commonly stout and at length 

 3-4 feet high. -Flowers small, greenish ; the petals yellowish : anthers pur- 

 plish-orange color. 



31. (S. erosa (Pursh) : nearly glabrous ; leaves oblong-lanceolate, acute, 

 erosely-toothed ; stem naked ; panicle oblong, with divaricate loosely- 

 flowered branches; pedicels filiform. — Pursh, fi. 1. p. 311; Don, Saxifr. 

 I. c. p. 360 ? 



"In stony rivulets on the high mountains of Virginia and Carolina. June 

 —July. — Resembles the foregoing (S. Pennsylvanica) in some respects very 

 much." Pursh. — We have seen a mere fragment of Pursh's plant in the 

 herbarium of the late Prof. Barton, and a still more imperfect specimen in 

 Mr. Lambert's herbarium, from which it appears that the species is much 

 more allied to S. Pennsylvanica than to any other ; but we greatly doubt 

 whether the cultivated plant described by Don, (or by Seringe in De Can- 

 doUe's Prodromus) is the same with that of Pursh. Hence we have retained 

 the original phrase of the latter author, and leave the species for farther ob- 

 servation. 



'!■ 32. S. hieracifolia (Waldst. & Kit.) : scape strict, a little hairy ; leaves 

 petioled, obovate-spatulate, repandly-toothed, ciliate, coriaceous ; flowers 

 spicate, subsessile ; lobes of the calyx ovate, broad, as long as the tube ; 

 petals ovate (reddish), marcescent, scarcely as long as the calyx ; filaments 

 purple ; capsules prominent, purple ; carpels divaricate at the apex ; styles 

 very short ; stigmas somewhat hemispherical. Seringe. — " Waldst. S^' Kit.

Arctic America, from Greenland and the Arctic Islands ! to Kotzebue's 

 Sound ! and the Bay of Eschscholtz. — It appears, as Hooker remarks, ex- 

 actly intermediate between S. Pennsylvanica and S. nivalis, more allied, 

 however, to the former. 



33. iS. integrifoUa (Hook.) : very viscidly pubescent throughout ; leaves 

 all radical, ovate, very obtuse, entire, or very slightly sinuate-crenate, some- 

 what membranaceous (copiously retictilately veined) ; scape elongated, 

 naked, paniculate at the apex ; panicle loose, broad or contracted, bracteate ; 

 petals obovate, twice the length of the glabrous spreading or at length re- 

 flexed segments of the calyx ; stamens short ; ovary free ; styles widely 

 divergent. Hook. ! fl. Bor.-Am. 1. p. 249, /. 86. 



Near the mouth of the Oregon River, i)/-. 6Vo«?e?-/ Mr. Tolmie! Nuttall! 

 — Caudex somewhat woody. Leaves short in proportion to the height of the 

 plant. Scape 6-12 inches high, quite leafless. Primary branches of the 

 panicle elongated, naked; the cymules either compact or quite loose. — Our 

 specimens all differ from the above specific character, as copied from Hook- 

 er, in the quite veinless leaves : in this and every other respect they fully 

 accord with his excellent figure ; whence we conclude that the phrase " copi' 

 ose reticulatim venosis,^^ was introduced by mistake.
