when he renamed " Mr. Brown's /S. arctica." His name was 

 an evident homonym, for, while S. Brownii Bebb was pub- 

 lished in 1889, S. Brownei (Anderss.) Lundstr. had been 

 published in 1877. Sadder still, the latter is even more 

 closely related to S. arctica R. Br. than was S. arctica 

 Pallas. Indeed, it was first established by Andersson in 1868^ 

 as a variety of his /S. arctica Pallas (= /S. arctica R. Br.). 

 Mr. Bebb was fully aware of this variety, even if ignorant of 

 its elevation to specific rank, when he named his S. Brownii. 

 We can attribute his action only to a strong desire to com- 

 pensate the wrong done by Andersson to the labor and 

 memory of Robert Brown. But in thus using a name which 

 he knew to be occupied he deliberately laid himself open to 

 the very charge on which he had just scored Andersson so 

 severely, and left the nomenclature of the species in worse 

 shape than he found it. I shall not rename the plant now for 

 I believe the name which has been in use for eighty years {8. 

 arctica R. Br.) can yet do duty until both the numerous 

 variations and the synonymy have been given careful study. 

 As indicated by the numerous descriptions, the leaves of this 

 variety vary much in both size and shape. It is rarely mis- 

 taken for any other species, however. It approaches most 

 nearly, in its larger forms, to small specimens of the Rocky 

 Mt. form of S. glauca.
