tina vulgaris. The name does not hold for the species owing to

10. Padus, is of late again coming to be recognized as a 
genus distinct from Prunus. It includes the Choke-Cherries and 
is to be attributed to P. Miller, and not to Borckhausen. 
11. Toxicodendron, Poison Oak or Poison Ivy, has been 
recognized as a valid segregate from the Linnaean Rhus, and has 
been attributed to P. Miller.* Duhamel had restored it. 
Toxicodendron, Duhamel, 1755.
