CONTRIBUTIONS TO THE NATURAL HISTORY OF ALASKA. 69 



A. peregrinus, Pursh. Unalashka, Norfolk Sound. (Abundant throughout the Aleutian 

 Islands. Usually solitary stalks. On some of the islands this plant blooms until covered with snow 

 in the middle of November. Where the roots have beeu covered by heavy snow-drifts at elevations 

 of 1,500 feet it is the last plant to flower in spring; the colors of which vary from lightest pink to 

 blueish. T.) 



A.foliaceus, Lindl., Unalashka. 



A. salsuginosus, Biohards., Sitka, Unalashka, Kotzebue Souud. 



A. alpinus, L., Unalashka, 2,000 feet above sea-level. 



A. sibiricus, L., including, after J. D. Hooker and Fries, A. montanus, Richards, and A. 

 richardsonii, Spr. Kotzebue Sound, Unalashka, Point Barrow. 



Erigeron uniflorum. L., (Following Fries, I include under this species E. pulchellum, D C, as 

 a variety. There is unquestionably good ground for the union. — J. T. Rothrock.) Unalashka, 

 Cape Lisburne. 



E. glabellum, Nutt., Wainwright Inlet to Mackenzie River; var. aspersum, Fort Yukon. 



Solidago virga-aurea, L., Unalashka to Kotzebue Sound Cape Lisburne, and on northern coast; 

 var. multiradiata, Fort Yukon. 



8. confertifiora, D C, Unalashka, Cape Mulgrave, Kadiak. 



Ptarmica borealis, D C, Sitka. 



P. sibirica. Unalashka, Eschscholtz Bay. 



P. speciosa, D 0., given by Ledebour, on the authority of J. G. Gmelin, as a native of this 

 region. 



Achillea millefolium, L., Norton Sound, Unalashka, Sitka, Fort Yukon. 



Leucanthemum integrifolium, D O, Kotzebue Soiind ; Saint Lawrence Island, and from Point 

 Barrow to Mackenzie River.. 



L. arcticum, D C, Norton Souud to Washington Inlet. (Abundant at Saint Michael's and 

 throughout the Aleutian Islands; growing along the beach in solitary stalks, with roots much ex- 

 posed. The leaves of this plant at Saint Michael's are very fleshy. . T.) 



Matricaria discoidea, I) C, Sitka, Unalashka. 



M. inodorata, L., Kotzebue Sound, var. eligulata, Norton Sound. This may be yet entitled to 

 specific rank, as Seemann suggests. 



Tanacetum kotzebuensis, Bess., Cape Espenberg, fide Ledebour ex Eschscholtz. 



T. huronense, Nutt., Fort Yukon. 



Artcmesia borealis, Pallas. Kotzebue Sound, Arctic coast, and what seems to be a variety 

 with glomerate, almost capitate, inflorescence, from Sitka. 



A. vulgaris, L., var. tilesii, Fort Saint Michael's and western and northern coasts. 



A. glomerata, Ledeb. ? Kotzebue Souud. 



A. androsacea, Seem., Bot. Herald, tab. 6 ; A. glomerata of Hooker and Arnott, Bot. Beechey, 

 but not of Ledebour, fide Seemann. This, it is thought by Dr. Hooker, may prove " an arctic, 

 tufted variety of some better-known plant." 



A. globularia, Cham., Unalashka, Saint Lawrence. 



A. arctica, Less., Cape Lisburue and Point Hope, and possibly Sitka. 



A. chamissonis, Bess., Seemann states that though A. arctica and A. chamissonis are by some 

 authors united, they may be at once distinguished by their different habits. 



A. absinthium, L., Given by Ledebour (Flora Rossica), on the authority of J. G. Gmelin, as a . 

 doubtful native of Russian America. 



Onaphalium sylvatieum, L., Russian America, fide Ledebour ex J. G. Gmelin. 



Antennaria alpina, Gaert., including A. monocephala, D C. Kotzebue Sound, Saint Lawrence 

 Island and Unalashka. (Common throughout the Aleutian Islands, growing in stools among the 

 clefts of rocks on the sides of the drier ravines. T.) 



A. dioica, Gaert., Islands adjacent to the American coast, Ledebour ex J. G. Gmelin. (Com- 

 mon throughout the Aleutian Islands ; grows in the clefts of the drier rocks on the faces of 

 bluffs. T.) 



A. margaritacea, R. Br., Sitka, Unalashka. (Abundant throughout the Aleutian Islands, 

 growing on the drier hillsides. Bare at Saint Michael's. T.)
