Eucalyptus L'Herit. is one of Australia's largest genera, with over 700 species (Brooker & Kleinig 1994).
Despite its importance in the Australian flora and in the Australian economy, numerous questions of systematic
relationships within the genus remain to be addressed.
The series Viminales (subgenus Symphyomyrtus)
contains about 40 species, is
characterised by markedly different
adult and juvenile foliage, and includes
Australia's most important temperate
hardwood plantation species (E. nitens,
E. globulus). Despite numerous morphological
studies and some chemical studies, the delimitation and subdivision of species within the series Viminales
remain problematic (Chappill & Ladiges
In cases where morphology has not
effectively resolved phylogenetic relationships
among taxa, chloroplast DNA
has frequently proved to be highly
informative at the species level and
above. By cutting the DNA with specific
enzymes, a 'fingerprint' of the cpDNA
can be constructed. A particular chloroplast
DNA 'fingerprint' is often referred
to as a 'haplotype' (a haploid genotype).
