Synopsis Rosarum Spontanearum Europæ Mediæ: Übersicht über die mitteleuropäischen Wildrosen mit besonderer Berücksichtigung ihrer schweizer-ischen Fundorte

Abstract

THE publication of this monograph marks a definite stage in the history of the taxonomy of Rosa and also raises important questions of more general interest. It represents the consistent labours of half a century of the eminent rhodologist, Dr. Robert Keller, of Winterthur, who is to be congratulated on the crowning achievement of his life's work. It is probably the last word on the problem of species in Rosa of the purely morphological school of taxonomy before the new genetical taxonomy takes up its inevitable position as an exact science on an experimental basis. In his foreword, Dr. Keller remarks that the parents of the 428 natural hybrids described have been determined morphologically and not experimentally. That expresses in a sentence the fundamental diference between the old and the new taxonomy.
