Following the Botany of California this would probably be referred 

 to the true P. contorta, of Douglas, and the first named to P. 

 contorta, var. Murray ana ^ though the characters, as I find them, 

 do not quite agree. I have thought best to leave the determina- 

 tion indefinite. 



Tsuga Mertensiana Carriere. Port Townsend, W. T. ; Victoria, B. C, and common 

 along the coast. Specimens from Fort Wrangel. 



This is the "hemlock" of these parts, and some of the trees at 

 Sitka and Fort Wrangel were as large, at least, as the best spec- 

 imens of the hemlock found at the East. 



Tseudtsuga Douglasii Carriere. Port Townsend, W. T. ; Victoria, B. C. ; Sitka, 



Alaska. 

 Thuja gigantea Nutt. Port Townsend, W. T.; Victoria, B. C. ; Kaigan, Alaska. 



Common along the coast. • 



This, Tsuga Mertensiana, and alders, form most of the arbor- 

 escent vegetation of the southeastern Alaskan coast. 



OBCHIDACEJE. 



Habenaria dilitata Gray. Port Townsend, W. T. 



As it seems to me, though it may be a form Qf .S. leucostachys, 

 Wat. 



H. hyperborea Bartlett Bay, in glacial drift. 

 Spiranthes Bomanzoffiana Cham. Bartlett Bay, Alaska. 



IRIDACE^. 



Sisyrincbium anceps L. Sitka 



Not abundant, but probably indigenous. 



LILIACE^, 



Allium acuminatum Hook. Victoria, B. C. 



Brodiaea lactea Watson. Port Townsend, W. T. ; Victoria, B. C. 



B, grandiflora Watson. Victoria, B. C. 



An imperfect specimen ; probably belongs here. 



Frosartes Oregana Watson. Victoria, B. C. 



Smilacina bifolia, var. dilitata Wood. Sitka, Fort Wrangel, and many places along 

 the coast, but seldom found in fruit. 



The fruiting specimens here from Sitka, have also three, and 

 sometimes four, leaves on the scape. 



Streptopus amplexifolius D. C. Fort Wrangel, Alaska. 

 Tofieldia glutinosa Willd. Bartlett Bay, Alaska.
