smaller than the ordinary European forms, and have fewer veins in the se- 

 pals and fewer sela; to the scales: they af^ree almost wholly with authentic 

 specimens of P. palustris /?. tenuis, Wtilil, from Lapland. — We take llie cha- 

 racters of this and the two foUowin^f nearly allied species from Hooker, not 

 beins: perfectly satisfied of their distinctness. The sets in these species do 

 not appear to furnish well-marked characters: we observe 7-12 in the Ameri- 

 can P. palustris, 5-8 in P. parviflora, Hook., and 3-5 in P. Kotzebuei. 



-f^2. P. parviflora (DC.) : very slender ; scales with about 5 very; slender 

 'setae ; radical leaves ovate, attenuate into a petiole ; the cauline one linear-ob- 

 long, sessile. Jlook. — DC. prodr. 1. p. 320; Honk.! Jl. Bor.-Am. 1. p. 82,

Sandy banks of rivers among the Rocky Mountains, Drummond! ex 

 Hook. IV. America, DC, who described from a specimen in the Banksian 

 herbarium. — Scapes from a span to a foot high, with a single bract-like leaf. 

 Flowers considerably smaller than in P. palustris : petals slightly unguicu- 

 Jate. Hook. 



-7—3. P. Kotzebuei (Cham. & Schlecht.) : scales with 3 slender seta^; radi- 

 cal leaves (and cauline one when present) subcordate-ovate, petioled ; petals 

 about 3-nerved, shorter than the calyx. Hook. — Cham. ^ iivhhxht. in Lin-

Unalaschka and Kotzebue's Sound, Cliamisso ; Rocky Mountains, be- 

 tween lat. 52^ & 56° {Drummond) to Bear Lake and the shores of the Arc- 

 tic Sea, Richardson ! — Scapes slender, naked or with a single leaf near the 

 base, 3-6 inches high. Leaves membranaceous, very small. Sepals ellipti- 

 cal-lanceolate. Petals elliptical. Anthers subrotund. Ovary oval-globose, 

 nearly a third part inferior. — Hooker, and also Cham. & Schlecht., expressly 

 state the stigmas to be four and the capsule 4-valved, as in the rest of the 

 genus, and this we find to be the case in our specimens ; but the figure in 

 the Flora. Boreali- Americana exhibits several views of a pentacarpellary 

 ■capsule, probably a monstrosity. 



— ^ 4. P. Caroliniana (Michx.): scales of 3 stout and thick sterile filaments, 

 ■distinct to near the base, about the length of the fertile stamens ; i)etals sub- 

 sessile, more than twice the length of the calyx, with strong greenish veins; 

 leaves (coriaceous) orbicular-ovate or somewhat elliptical-ovate^ subcordate, 

 the cauline one usually low down and clasping. — Michx. Jl. 1. p. 184; Bot.

Wet meadows and along shady streams, &c. Canada ! to Florida I Avest 

 to the Mississippi. 0. New-Orleans, Drummond. July-Aug. — Leaves 

 about 7-nerved, varying from orbicular-subreniform to ovate-cordate and 

 broadly oval with no sinus at the base. Scape 8-18 inches high. Flower 

 an inch in diameter. — We have seen no Southern specimens which agree 

 with the /?. of Hooker in the sterile stamens, &c. ; but Elliott describes them 

 as " nearly the length of the corolla," and " filaments very short." 



5. P. asarijolia (Vent.) : scales of 3 sterile filaments ; petals broadly 

 ovate and very obtuse, naked and abruptly unguiculate at the base ; leaves 

 reniform; the cauline one reniform-cordate or somewhat orbicular, sessile.—
