Abstract
On the basis of symposium contributions onChlorella, Hibbertia, Eucalyptus, Ambrosia and on numerical approaches some fundamental problems of (bio)systematics, evolution, and taxonomic categories are discussed: Methods available for analysing “affinities”; conflicting evidence from phenetic, biochemical, cytogenetic and other analyses; further classification problems in cases of “intermediacy”, etc. While “sibs” of various levels and their “natural” hierarchy often can be objectively defined, this appears impossible for particular taxonomic levels itself (e. g. “species”). A single objective taxonomic system of organisms is unrealistic. Certain guiding lines for relative and practicable concepts of “species” and “genus” are proposed.
