 Mr. Tohnie! — This species cannot be the original S. punctata of Linna3us 

 (which is perhaps S. Davurica, Willd. as Fischer suggests), and probably is 

 not the plant of the second edition of the Species Plantarum ; and hence we 

 have adopted the name long since proposed by Fischer, wlio was the first to 

 rectify the synonymy. The name S. arguta, Don, has the priority, if we 

 are correct in adducing it here ; but of this there is some doubt. To the va- 

 riety with compact inflorescence, we refer the S. Nelsoniana, Don, as well 

 from the description, as on the authority of Fischer, who has labelled the spe- 

 cimen in the Banksian herbarium, " S. semidodecandra, Wormskiold,'''' which 

 he adduces as a synonym of his S.. gestivalis. S. heterantha appears to be a 

 bulbiferous variety of the same species. — Flowers small : petals 1-nerved, or 

 occasionally with two indistinct branches. Styles very short. 



17. <S. arguta (Don) : leaves roundish-reniform, incisely serrate, glabrous ; 

 petioles filiform ; scape slender, smooth ; segments of the calyx oblong, 

 acute. — Don, Saxifr. I. c. p. 356 ; Seringe, I. c. ; Hook.! fi. Bor.-Am. 1. 

 p. 252. 



N. W. Coast, Menzies. — Panicle very simple. Flowers white, the size 

 of those of S. stellaris. Segments of the calyx oblong, acute. Petals oval, 

 unguiculate, many-nerved. Pistils very short, Don. — Probably S. aestivalis. 



18. S. nudicaulis (Don) : leaves reniform, palmate, glabrous ; flowers 

 paniculate; segments of the calyx acute; scape naked. — Don, Saxifr. I. c. 

 p. 366 ; Seringe, I. c. ; Hook. I. c. 



N. W. Coast, Mr. Nelson. — Scape 4-5 inches high, nearly glabrous. 

 Lobes of the leaves ovate, mucronate. Flowers as large as in S. rivularis, 

 white. Calyx and pedicels clothed with glandular hairs. Petals small, 

 obovate, 3-nerved, a little longer than the calyx. 



19. S. Mertensiana (Bongard) : scape nearly naked ; leaves roundish, in- 

 cisely somewhat lobed; the lobes slightly 3-toothed ; peduncles glandularly 

 pubescent ; sepals ovate, rather acute ; petals ovate, acute, \vith very short 

 claws, 3-nerved. — Bongard, veg. Sitcha, I. c. p. 141. 



Sitcha. — Leaves cordate at the base, and cuneately decurrent into the 

 petiole, li-2 inches broad. Scape simple, about a foot high. Flowers 

 panicled : pedicels filiform. Ovary ovate, about the length of the styles. 

 Bongard. 



20. S. neglccta (Bray) : stems numerous, filiform, glabrous, nearly leaf- 

 less ; radical leaves on long petioles, cuneiform at the base, deeply toothed 

 at the apex, glabrous ; bracts linear, obtuse, minute ; sepals lanceolate-ovate ; 

 petals lanceolate, scarcely longer than the calyx. Seringe. — Bray, ex Sternb.

Bay of St. Lawrence, Chamisso. — Flowers small, white. 



21. S. rejlcxa (Hook.) : canescently pubescent; leaves ovate, rather coria- 

 ceous, opaque, incisely serrate, attenuate into a petiole ; scape naked ; pani^
