Populus candicans Alton 

 Shore of Lake Ontario, east of Oswego. H. D. House, July 29, 

 1914, No. S779' Large trees growing with Populus del- 

 toides, Populus balsamifera and other hardwoods, 

 appearing native but perhaps adventive. The origin of this species, 

 which is common in cultivation and freely escaping, known popu- 

 larly as the balm of Gilead, seems never to have been definitely 

 settled, although it has been suggested that it has an Asiatic origin. 

 It was described in 1829 by Desf ontaines as Populus o n t a r i - 

 e n s i s , and there are numerous references to the species in litera- 

 ture which seems to indicate that the species is native to the Great 

 Lakes region and westward to Montana, where the writer has seen 

 it growing on the shores of Lake McDonald.
