SKETCH OF THE FLORA OF Al ASKA. 443 



Cardamine Lenensis, Andre, Island of St. Lawrence, Ounalaslika and Sitka; 

 vide Ledebour, Flora Rossica. 



0. pratensis, L., Kotzebno sound, and between Point BaiTow and Mackenzie 

 river ; Norton sound, H. M. Bannister. 



0. liirsuta, L., Ounalasbka and Sitka. 



C. purpurea, Cham., Kotzebue sound, Wainwright inlet, and Island of Oun,".- 

 laslika. 



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

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

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



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

 in Flora Rossica simply tells us (on the authority of Stellcr and Ivrasch) that it 

 is "in ora occidentali AmericaB borealis." 



Panya macrocarpa, R. Br., Kotzebue sound, Capo Lisbumo, between Point 

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



Draba algida, DO., Island of St. Lawrence. 



D. alpina, L., Kotzebue sound. 



D. glacialis, Adams, Oapo Lisburno, Assistance bay, and Garry island. 



D. stellata, Jacq., var. hobecarpa, Kotzebue sound, Oiinalashka; and fide 

 Ledebour Flora Rossica in Island of St. Lawrence. 



D. hirta, L., Kotzebue sound. 



D. incana, L., Gaixy, St. LawTcnce, and Ounalashka islands. 



D. gracilis, Ledeb., Ounalashka. 



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

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



D. Unalaschkiana, DG., "a var. D. borealis?" Ledebour, op. citat., Ouna- 

 lashka. 



D. stenoloba, Ledob., Island of Ounalashka. 



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



D. grandis, Langsdoi-fF, in DG., Systema, vol. ii, p. 355; var. siliquosa, Goch- 

 learia grandiflora, DG., Systema, vol. ii, p. 368; Gochlearia spathulata, 

 Schlecht. See Torrey and Gray, Flora of Xorth 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- 

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

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



Gochlearia fenestrata, R. Br., Norton sound to Point BaiTow and Assistance 

 bay. 



G. oblongifolia, DG., Sitka, Kotzebue sound, "Wainwright inlet, and between 

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

 nister. 



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



Tetrapoma pyrifonne, Seemann, tab. 2, Botany of Voyage of the Herald. Gol- 

 lected both in the vo^'ago 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 Gape Lisburae. 



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

 Barrow and Mackenzie river. 



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



Eutrema Edwardsii, R. Br., island of St. LanTence. 



Aphragmus Eschscholtzianus, Andi'z., Ounalashka. 



Hutchinsia calycina, Desv., Kotzebue sound and Gape Ivruzeustcm
