SKETCH OF THE FLORA OF ALASKA.. 451 



P. stricta, Horncm., after J. D. Hooker, 1. c, I include under tliis species 

 P. Ilornenuinniana and P. Mistassinica, both of C. and S. and of Micbx., 

 Kotzebue sound. 



Androsace Ghamaejasme, Willd., Kotzebue sound to Wainwrigbt inlet. 



A. septcntrionalis, L., Kotzebue sound and Charaisso island, Fort Youkou, 

 Antoine Houle. 



A. villosa is stated b}^ Ledebour to have been found at Kotzebue sound, in 

 Beechey's Voyage. I see no record of it in Hooker and Arnott's list of plants 

 collected there. Possibly it may be an oversight on Ledeboui^'s part. 



Dodecatheon Meadia, L., Sitka, Kotzebue sound, and Cape Lishurne. I can 

 find no valid grounds for keeping up the distinction l)etween D. i\Icadia, I). 

 integrifoliuni, and D. frigiduni. The last is proV)ably the most marked variety 

 of the number; but after a careful comparison of the forms comprising the genus 

 I think it safest to regard them as varieties of a widely distributed polymor- 

 phic species. 



Glaux maritima, L., Sitka. 



Trientalis Europsea, L., .Sitka, Norton sound ; H. M. Bannister. 



GEXTIANACE.S;. 



Gentiana Amarella, L., Sitka. 



G. acuta, Michs., Ounalashka. 



G. tenella, Rottb., Kotzebue sound. 



G. detonsa. Fries ; Point Barrow to Mackenzie river, Pullen ; Fort Youkon, 

 Antoine Houle. 



G. propinqua, Richards. ; G. Rurickiana, Kotzebue sound, Port Clarence, and 

 Norton sound, H. M. Bannister. 



G. Aleutica, Cham., Ounalashka. 



G. prostrata, Haenke, Ounalashka and Kotzebue sound. 



G. glauca, Pall., Kotzebue sound and Wainwright inlet. 



G. platypetala, Griesb.; Sitka, Eschscholtz. 



G. Douglasiana, Bong., Sitka. 



Pleurogyue rotata, Griesb., Kotzebue sound, river Buckland and Ai'ctic 

 coast. 



Swertia perennis, L., Kodiak, Dr. A. Kellogg ; S. perennis, L., van obtusa, 

 Kodiak, Dr. A. Kellogg. 



Villarsia Cnsta-galli, Griesb., Sitka. 



Menyanthes trifoliata, L., Ounalashka and Sitka. 



POLEMOXIACE^. 



Phlox Sibii'ica, L., Kotzebue sound. 



Polemonium caeruleum, L., Norton sound to Point Bairow; islands of St. 

 George, Ounalashka, and Chamisso ; Fort Youkon, Dall. I recognize but two 

 species of this genus belonging to northern North America — the one, P. reptans, 

 L., which is well marked, and the other P. caeruleum, L., as made up of all the 

 others. Numerous as the forms and wide as the extremes of the latter aggregate 

 species are, they can easily be connected. Even P. pulchellum, Bunge, which 

 is perhaps the best marked variety, shades off by insensible gradations into the 

 others. 



"^iapensia Lapponica, L., island of St. Lawrence. 



BOKRAGINACE^. 



Mertcnsia maritima, Don, Sitka, Norton sound to PoiQl~'Darrow and Cape 

 Bathurst. 



M. paniculata, Don, M. pilosa, DC; Kotzebue sound ; Fort Youkon, Antoino 

 Houle and Mr. Dall. 



M. Sibirica; Don; M. denticulata, Don, Kotzebue sound.
