THE VULPINA GRAPES 103 



species. Linnaeus described ;i Vitis vulpina ("fox-grape" in 

 1753, and preserved specimens of it in bis herbarium. Our 

 grapes have been so much misunderstood that there have 

 been various I the identity of Linnaeus' specimens. 



It lias been thought that they represent the true fox-grape, 

 or Vitia Lobruaca. Again it was thought that they are the 

 muscadine type, and the name vulpina was once used in 

 place of Biichanx's rotundifolia (page 98 . Then for many 

 years the oame was dropped altoi.o-tli.-r. Finally Planchon, 

 the ■•■ut monographer of the genus, declared Lin- 



asBUS 1 specimens to be the Vitia riparia of Michanx, although 

 be 'li'l not substitute the name vulpina for the more recenl 

 riparia. Professor Britton later examined the specimens, and 

 • pronounced them to be V. riparia. In the above mono- 

 ph I therefore used the older nam.- [V. vulpina). Since 

 that time, however, I have myself examined Linnaeus' speci- 

 mens in London, and find that he had specimens of two 



- under the name of vulpina < »n one sheet are two 

 leaves, one marked V. vinifera and the other V. vulpina, 

 both in Linnaeus' hand. The former is the wine-grape I 



. and the latter is the river-bank grape V. riparia). 



Another herbarium sheet, however, has a large flowering 



.men, labelled, in Linnaeus' hand, ''. vulpina, and this 



.i|"- V. cor di folia . It would have been better 



to have taken this latter Bpecitnen ax Linnieiis' type, ami to 



have made the name vulpina Bupplant cordifolia; but - 

 the other disposition has been made of the case, I shall not 

 make the change.
