Geographic variation in Eucalyptus Globulus Labill: including studies on the distribution and taxonomy of the species

Kirkpatrick, J. B. ( 1973)

The distribution of Eucalyptus globulus Labill, is described and discussed. Geographic variation is demonstrated in a number of seedling and adult characters. This variation appears mainly to relate to climatic factors. The stepped clinal variation pattern characteristic of the species probably has a divergent origin, although the possibility of an introgressive origin cannot be excluded. A new taxonomic treatment of E. globulus, based on numerical analyses and the geographic variation data, reduces three taxa previously regarded as species to the subspecific level.
