CONFUSION IN" NOMENCLATURE 



of this l) >ok, until I could personally examine the original Bpeci- 



I have now had the opportunity of examining the - 

 mens of Linnaeus and Aiton; also those of Willdenow and Link 

 at Berlin, and of Michaux al Paris; and through the courtesy of 

 Professor Dr. l!<<-k, I have obtained drawings and full notes ol 

 the specimens of Trattinniek at Vienna. 



Earing now Been the original types of i li«- American black- 

 berries and dewberries, I am able t<> make a new disposition of 

 the species. Linnaeus' Rubus Canadensis is unmistakably the 

 thornless blackberry, which \\ms described in 1891 by Britton as 

 Rubus Millspaughii p. 323 . Aiton's Rubus villosus is unmistak- 

 ably thf dewberry <>t' the North, the plant to which we have 

 Fore applied ih<- name Rubus Canaden II - specimens 



are mostly sterile shoots, and are from plants which were grown 

 in the Kew gardens. These specimens are Bhown in the illus- 

 tration mi page .'!7'_'. Ordinarily the dewberry i- noi villous, and 

 the name, therefore, is :i misnomer; but Aiton made the name 

 because the tips of the verdurous Bhoots of t 1 1 • - dewberry contain 



a villous pub< mce. These leafy tips of the dewberry are 



rarely Been in herbaria, and it i*. therefore, noi strange that 

 specimens of Aiton have been misunderstood; bul the 

 specimens are nevertheless unmistakably the dewberry. 



While the northern dewberrynow has a name (Rubus villo 

 the common high-bush blackberry is left nameless. Our nexl 

 •«•, therefore, is to look up the supposed Bynonyms of the 

 high-bush blackberry. The Rubus inermis described by Willdenow 

 in 1800, and credited by him to North America, is one of these 

 Bynonyms. The specimens in the Berlin herbarium are unmis- 

 takably a spineless form of Rubus ulmifolius of Gre< 



re, disposed of. The nexl name in order of pub- 

 lication is the Rubus argutus of Link, published in l s _"_'. Link's 

 specimens in Berlin are well presi rved, and are unmistakably the 

 form of high-bush blackberry which we have known as Rubus 

 • should be regarded a~ a Rood s|>. ,- : ,~; and 

 since Rubu was published two ier than 



that name must stand. Two pubi were described by 

 Raflnesque in hi* "Florula I. ' in l s i7 /.'
