1916] McAtee, — Plants of Matinicus Island 31 



( !orroborative testimony is to the effect that most of the cleared por- 

 tions of the island were once covered by ;i dense stand of yellow birch 

 and rock maple. Only one maple (doubtfully native) now remains. 



The only publications dealing with the plants of Matinicus Island 

 are the following: (1.) by Arthur H. Norton: "Some noteworthy 

 plants from the islands and coast of Maine." (Rhodora, 15, pp. 

 137-143, August, 1913), which records Sparganium angustifolium 

 Michx., Euphorbia polygonifolia L., Empetrum nigrum L. and Teu- 

 crium canadcnsc littorale (Bickn.) Fernald, two of which are addi- 

 tional to the following list; and (2.) "The genus Euphrasia in North 

 America" (Rhodora, 17, pp. 181-201, October, 1915), wherein 

 Euphrasia purpurea, var. farlowii forma iodantha n. f. is described 

 from a specimen collected on Matinicus by A. H. Norton.
