EuBATrs, or Blackberries and Dewberries, The botany of the American Blackberries and Dew- berries is interminably confusing. If the kind of spe- cies-making that has l>een applied to the European Rubi were applied to the American, the number of species would straightway be quadrupled or trebled at the least. There is no difiiculty in finding forms that are distinct enough to be described as species. The difficulty lies in the endless series of intermedi- ate forms, that confound all efforts at limitation and make printed descriptions of no avail. This difficulty is greatly increased from the fact that the foliage often differs widely between the verdurous and flower- ing shoots of the same plant. There seems to be little utility in separating forms that cannot be distin- guished in at least a fair proportion of the specimens that come to one's hand, however well marked they may be in their extremes. It is to be expected, how- ever, that long-sustained studies in the field, as well as in the herbarium, will discover means of separat- ing some of the forms that are now confused, but it is doubtful if there are any species in this section of Rubus, as the term species is commonly understood. The best one can do is to throw them into groups. For a history of nomenclatorial
