PAPAVERACEiE. 
5. Papaver nudicaule, Linn. spec. pi. p. 725. FI. Dan. T. 41. 
Pursh’s FI. p. 364, &c. The most liardy plant of the Polar regions, 
resisting the first frosts and remaining the last in flower. The leaves 
and especially the seeds, which are very oleaginous, are a great resort 
in scorbutic affections, and agreeable to the taste.—Dr. Kane. 
This plant was found at all the stations of the two voyages, and 
extends probably to the farthest limits of vegetation. 
CRUCIFER2E. 
6. Arabis alpina, Linn. FI. Dan. T. 62. Pursh’s FI. p. 427. 
Torr. and Gr. 1, p. 80. 
North Proven, 72°. 
7. Cardamine pratensis, /?. angustifolia , Hook. FI. Bor. Am. 1, 
p. 45. 
Sukkertoppen, 64°; Disco, 70°. 
8. Hesperts Pallasii, Torr. and Gr. suppl. p. 667. E. minima,

Cheiranthus Pallasii, Pursh’s FI. p. 436. C. pygmeeus , Adans. in 
D. C. prodr. 1, p. 137. Two fruitiug specimens 4-6 inches high, 
scarcely to be mistaken from Dr. Hooker’s fig. T. 19 of FI. Bor. Am. 
Leaves only apparently narrower by drying. Found at the extreme 
north point of Dr. Kane’s expedition, on Washington Land, 81° N. 
latitude. This plant was discovered by Pallas on the northwest coast 
of America, and never, I believe, in the Arctic Sea.

10. Draba alpina, a. Hook. FI. Bor. Am. 1, p. 50. B. alpina , 
Linn’s Herb, ex R. Br. Torr. and Gr. 1, p. 103. Silicles glabrous; 
flowers yellow; leaves less hairy than var. Just flowering, and of 
smaller size than fig. in T. 56 in FI. Dan 
North Proven, 72°. 
/?. R. Br. Spitzb. pi. in Scoresby’s Arct. Reg. Hook. FI. Bor. Am. 
1, p. 50. Torr. and Gr. 1, p. 103. Leaves, peduncles and silicles
