Abstract
A study of the genetic systems in the genoecodemes of the Senecio lautus complex
in Australia and New Zealand showed that the variation pattern of the complex may
be explained in the light of the genetic systems met with in the five Australian and one
New Zealand genoecodemes recognized previously. The probable course of evolution in
the complex is discussed, and it is shown that reproductive barriers are present between
mallee and montane genoecodemes, whereas other such groups are potentially capable of
exchanging genic material. The roles of indirect and limited gene exchange and human
influence on the evolution of this complex are discussed.
