to whom special acknowledgement is made for these and many 

 other important services. A few specimens from Hebron have 

 been sent by Mrs. Hlawatscheck. These large collections c )n- 

 tain nearly three score of species not included in former lists of 

 Labrador plants ; and, with the collections of the Bowdoin 

 College Expedition, they furnish so remarkable an addition to 

 our knowledge of that flora as to make desirable the preparation 

 of the following notes. 



In the list which follows, no attempt is made to enumerate 

 all the plants of either collection: the larger portion of them, 

 naturally, are well known northern species which have been 

 collected many times in Labrador. The species enumerated are 

 for the most part such as are not credited to Labrador by Mr. 

 James M. Macoun in his " List of [)lants known to occur on the 

 coast and in the interior of the Labrador Peninsula;'" 

 and such plants are indicated by the asterisk (* ) before 

 the name of the species. A few of these species are 

 included in Mr. Macoun's list from the valleys of the 

 Rupert and East Main Rivers and from James Bay, but not 

 from Labrador proper as defined in the eighth report of the 

 Canadian Survey (1895) and its accompanying maps. ^ Some cf 

 the species, not enumerated in Mr. Macoun's list but here in- 

 cluded, have been already noted from Labrador in the 

 contributions from the Herbarium of the Geological Survey of 

 Canada, in the Rev. Arthur C. Waghorne's " Flora of New- 

 foundland, Labrador, and St. Pierre et Miquelon " or elsewhere. 

 In these cases, however, the former record of the plant is noted. 

 While studying the two collections which are the principal 

 source of these notes occasional Labrador specimens of some of 

 the noteworthy species there represented have been found in 

 the Gray Herbarium, and for the sake of completeness records 

 of these are here included.

 lying east of a line drawn directly north from Blanc .Salilon to 52" N. lat., thence
