SKETCH OF THE FLORA OF ALASKA. 443 



Cardamlne Lenonsis, Andre, Island of St. Lawrence, Ounalaslika and Sitka, 

 ide Ledeljour, Flora Rossica. 

 C. pratensis, L., Kotzebue sound, and between Point BaiTow and Mackenzie 

 river; Norton sound, H. M. Bannister. 

 C. kirsuta, L., Ounalaslika and Sitka. 



C. purpurea, Cham., Kotzebue sound, Wainwriglit inlet, and Island of Ouna- 

 lasLka. 



G. digitata, Richards., (possibly only a forjn of C. pratensis ; fide J. D, Hooker 

 in " Outlines of the "Distribution of Arctic Plants,") Waiuwright inlet, between 

 Point Barrow and Mackenzie river; Island of St. Lawrence. 



Alyssum hyperboreum, L. — A doubtful native of North America. Ledebour 

 in Flora Rossica simply tells us (on the authority of Steller and Ivi-asch) that it 

 is "in ora occidentali Araericse borealis." 



Panya macrocarpa, R. Br., Kotzebue sound, Cape Lisburne, between Point 

 Barrow and Mackenzie river, and Island of St. Lawrence. 



Draba algida, DC., Island of St. LawTcnce. 



D. alpiua, L., Kotzebue sound. 



D. glacialis, Adams, Cape Lisburne, Assistance bay, and Gariy island. 



D. stellata, Jacq., var. hebecarpa, Kotzebue sound, Ounalaslika; and fide 

 Ledebour, Flora Rossica in Island of St. Lawrence. 



D. hirta, L., Kotzebue sound. 



D. incana, L., Gany, St. Lawrence, and Ounalashka islands. 



D. gracilis, Ledeb., Ounalashka. 



D. borealis, DC, islands of Ounalashka and St. Lawrence. Perhaps only a 

 leafy form of D. incana, according to J. D. Hooker, 



D. Unalaschkiana, DC., "an var. D. borealis?" Ledebour, op. citat., Ouna- 

 lashka. 



D. stenoloba, Ledeb., Island of Ounalashka. 



D. muricella, Wahl. ; D. nivalis, Liljebl., Wainwright inlet. 



D. grandis, Langsdorff, in DC, Systema, vol. ii, p. 355; vai*. siliquosa, Coch- 

 learia grandiilora, DC, Systema, vol. ii, p. 368; Cochlearia spathulata, 

 Schlecht. See Torrey and Gray, Flora of North America, vol. i, p. 110. 

 Draba grandis is figured in Del. Icon., 2, tab. 47. One specimen differs from 

 the figure mainly in having longer and less turgid pods, and the leaves being 

 rather more entire ; but it is without doubt the same plant. A foot-note in Lin- 

 naea, vol. ii, p. 27, throws much light on its otherwise rather complicated synon- 

 ymy. This plant had not been found in Sitka previous to its recent discovery 

 there by Mr. Bischoif, the nearest known approach hitherto being Ounalashka. 



Cochlearia fenestrata, R. Br., Norton sound to Point Barrow and Assistance 

 bay. 



0. oblongifolia, DC, Sitka, Kotzebue sound, Waiuwright inlet, and between 

 Point Barrow and Mackenzie river ; also found at Norton sound by Mr, Ban- 

 nister. 



C Anglica, L., Kotzebue sound and Assistance bay, 



Tetrapoma pyriformc, Seemann, tab. 2, Botany of Voyage of the Herald. Col- 

 lected both in the voyage of the Herald and later by Mr. Bannister at Fort St. 

 Michaels, at Norton sound. Seemann regards it as introduced from Asia by the 

 Russians. He is probably correct, as it has not been found elsewhere in North 

 America. 



Hesperis Pallasii, T. and G., Kotzebue sound and Cape Lisburne. 



Sisymbrium Sophia, L., var. sophioides, Kotzebue sound, and between Point 

 Barrow and INIackenzie river. 



Erysimum lanceolatum, R. Br. ; Arctic coast, Pullen. 



Eutrema Edwardsii, R. Br., island of St. La^\Tence. 



Aphragmus Eschscholtzianus, Andi'z., Ounalashka. 



Hutchinsia calycina, Desv., Kotzebue sound and Cape Kmzenstem
