SKETCH OF THE FLORA OF ALASKA. 451 



P. stricta, Homem., after J. D. Hooker, 1. c, I include under this species 

 P. Hornemanniana and P. Mistassinica, botli of C. and S. and of Michx., 

 Kotzebue sound. 



Androsaco Chamsejasme, Willd., Kotzebue sound to Wainwriglit inlet. 



A. septentrionalis, L., Kotzebue sound and Chaniisso island, Fort Youkon, 

 Antoine Houle. 



A. villosa is stated by Ledebour to have been found at Kotzebue sound, in 

 Beechej'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 Ledebour's part. 



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

 find no valid grounds for keeping up the distinction between D. i\Ieadia, I). 

 integrifoliuni, and D. frigidum. The last is prolmbly 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 Europaea, L., Sitka, Xorton sound ; H. M. Bannister. 



GEXTIANACE^. 



Gentiana Amarella, L., Sitka. 



G. acuta, Michx., Ounalashka. 



G. teuella, 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. Bannistei'. 



G. Aleutica, Cham., Ounalashka. 



G. prostrata, Hsenke, Ounalashka and Kotzebue sound. 



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



G. platypetala, Griesb.; Sitka, Eschscholtz. 



G. Douglasiana, Bong., Sitka. 



Pleurogyne rotata, Griesb., Kotzebue sound, river Buckland and Arctic 

 coast. 



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

 Kodiak, Dr. A. Kellogg. 



Villarsia Crista-galli, Griesb., Sitka. 



Menyanthes trifoliata, L., Ounalashka and Sitka. 



POLEMOXIACE^. 



Phlox Sibirica, L., Kotzebue sound. 



Polemonium cteruleum, L., Norton sound to Point Barrow; islands of St. 

 Georj'e, 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 otlier P. casruleum, L., as made up of all the 

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

 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. 



BOREAGINACE^. 



Mertensia maritima, Don, Sitka, Norton sound to Point iJarrow and Cape 

 Bathurst. 



M. paniculata, Don, M. ))ilosa, DC ; Kotzebue sound; Fort Youkon, Antoine 

 Houle and Mr. Dall. 



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