Hab. Labrador. Kohlmeister, Dr Morrison. Hudson's Bay. Dr Wriyht. Woody country between 

 lat. 54** and QAi'^. Dr Richardson. — My Labrador specimens thus referred to this plant, are too imperfect 

 for me to venture to offer a character from them. Dr Richardson's ** S, Ammanniana ?" appears to me to 

 be the same with this,

Rab. Kotzebue's Sound. Beechey. Arctic Sea-shore. Dr Richardson (whence, however, only one 

 specimen was brought home).— A very distinct and beautiful species, with glossy, strongly nerved, perennial 

 leaves, the skeleton nerves remaining in the lower parts of the stem. Ovaries and fruit very large in pro- 

 portion to the size of the plant.

Hab. Unalaschka. Chamisso in Herb. no^^r.—Chamisso doubts if this be the true S. polaris of 

 Wahlenberg, on account of the glabrous ovary. It does not seem to have been elsewhere found in Arctic 

 America ; but I have specimens gathered by Sir Edward Parry's officers in Spitzbergen. 



(Many specimens of Salxx yet remain in the British N. American Herbarium, in too imperfect a state to 

 be determined. Chamisso quotes the S. arctica of Pallas (not Br.), a very dubious species it must be con- 

 fessed, as "a native of Ifnalaschka, and S. glauca, L. and Koch. (5. sericea, Vill. and Ser.), of Chamisso's 

 Island and Cape Espenbcrg, in Bchring's Straits. Bongard, in his ''Veget. de Sitcha^ gives the following 

 brief character of " 5. Sitchensis,*' Sanson, »25^:— ''amentis fructiferis breviter pedunculatis, pedunculo 

 subfoliato ; capsulis ovato-lanceolatis tomentosis pedicellatis, pedicello nectarium S-S-superante, stylo elongate, 

 stigmatibus bifidis (?) ; foliis oblongo-obovatis obsolete crenulatis, supra pubescentibus, subtus cano-tomen- 

 tosis."— A single specimen, with foliage only, which M. Bongard has kindly communicated to me, does not 

 enable me to refer it to any previously described species).
