Abstract

Two morphologically similar populations of Diuris semilunata Messmer, each having basic differences in flower colour (Black Mountain: flower yellow and lightly blotched and Mount Jerrabomberra, N.S.W.: flower orange yellow and heavily blotched), were examined genetically using starch gel electrophoresis. There was no significant difference in the allele frequency in seven polymorphic enzyme systems observed, thus both populations are genetically similar and the observed differences in flower colour were not due to the alleles studied.
