282 THE CANADIAN NATURALIST. [^^g* 



Lastrea Filix-mas is erreneously referred to in some American 

 works on Materia Medica as a common North American and 

 Canadian fern. It has recently, however, been found on the 

 Rocky Mountains by Br. Parry. Professor Gray says that Dr. 

 Parry's specimens are apparently identical with the European 

 plant. Nothing like it occurs in Canada, so far as I can ascertain. 

 Varieties of L. marginalis have been sent to me under the name 

 of L. Filix-mas.

 stipe with few pale scales. Lastrea cristata, Presl, Moore, &c.
