 This Ciic/iiiilnirinn is ahiiiMlaut in tlu' rc^jriou of tiio typf locality of Micliaiix's 

 l.ciiislictiiii aclni'lfoHiiiii, associated witli A. .•<c(illili-itiii i>.,\vliicli .Micliaiix collected at 

 till saiMc station. Sucli a [ilant could liardly have cscaju'd him, and he would nat- 

 urally associate it with L. xcdlhirinii. I?esides, it is the only jilant of the I'e^ioii 

 uliicli a^Tees with the original description of J,, (icldrifiiliiini. Therefore, while we 

 lia\(' not st'Cii the type specimen, we t\'el justified in identifying; Michaux's jilant as 

 (iiu- ' 'iiilnjilriirinn of the northeast coast, heretofore referre<l to tlu' Alaskan ('. tjiiiclliii. 

 A form from the "rocky shore of the St. Lawrence, Temiscoiiata, Canada," col-
