A descriptive system for corona analysis inAsclepiadaceae andPeriplocaceae

  • Sigrid Liede
  • Henning Kunze


A general system for description of the corona in theAsclepiadaceae is introduced. It is based on the identification of the components constituting the corona, the relationships among those components, and the relationships among those components and other floral features. The components can be placed in both an evolutionary and ontogenetic context, the latter allowing the identification of homology problems. This approach to corona description reveals certain evolutionary constraints in that some possible combinations of components are not realized.
