Abstract

There are about twenty-two, more or less unstable,
forms of Eucalypts native of Tasmania which, may be regarded
as distinct species. The variations of some of
these are very puzzling to the student, and have been responsible
for much confusion. Some of the species respond
profoundly to change of conditions, especially soil.
Hybridisation is fairly common with many species, and is
responsible for some temporary confusion, and perhaps permanent
change. There is a further evolution progressing in
response to internal and unknown causes, not in the small
fluctuating variation present in the offspring of every
organism, but in sudden mutation. With some of our
species, especially Blue Peppermint, from seed carefully
gathered off the one tree, it is common to find conspicuous
distinction of form amongst the offspring. There is a
large field of research in all three forms of variability
open to the student; very little has been done, and we
shall not properly understand the limitation of species
until it is.
