The natural distribution of Eucalyptus species in Tasmania - Forestry ...

and western populations, but may also be
due to misidentification of E. ovata given the
correspondence between their respective peaks
in spring flowering time (cf. Figures 14, 49).
COMMENTS: The disjunct distribution of
E. brookeriana requires clearer ecological and
taxonomic definition, considered in context
with the distribution of E. ovata, particularly
in western regions. In ambiguous cases,
botanists in the field have probably classified
populations conservatively as the more widespread
E. ovata. This predilection is reflected
in the small number of verified, outlier
occurrences of E. brookeriana between the
eastern and western population centres. For
example, E. brookeriana has been verified south
of Deloraine at Golden Valley (cells 4739, 4740;
M.I.H. Brooker, pers. comm. 1996), and other
locations within this region require verification
(cells 4638, 5035). Recent records from southwestern
coastal regions (e.g. cell 5628) also
suggest a more extensive distribution than
is shown here. In the south-east, unverified
outliers for E. brookeriana are recorded from
the vicinity of Woodbridge Hill (cell 5122),
Snug Tiers (cell 5123) and Forestier Peninsula
(cell 5724). In the north-east, voucher records
in the vicinity of Mount Barrow (cell 5342)
add credence to the unverified outlier east of
Goulds Country (cell 5943).
