Peninsula. Although the migration is generally southwards, one 
species, Cynthodes accerosa R.Br., not occurring on the Nepean 
Peninsula, suggests a northward migration. It is a Tasmanian 
shrub found at only two points in Victoria, on the high granitic 
cliffs at Wilson’s Promontory and Cape Woolamai. 
It will be noted that, in the above list. Eucalyptus does not 
appear. The author, during his geological survey of a large 
portion of the limestone surface of the Nepean Peninsula, noted 
its absence and the prevalence of Melaleuca arid Leptospermum. 
In regard to the absence of eucalypts, the Peninsula differs from 
the limestone surface at Buchan in eastern Victoria, which is 
lightly timbered with two species of it. Many of the forms of the 
Cheltenham Flora (Patton, 1932) on the shore of Port Phillip 
further north, are absent, due no doubt to their development on 
siliceous sandy beds containing very little lime. 
The Nepean Peninsula vegetation is not that of a dune flora, 
although the dune topography has been preserved, hence the local 
name “The Cups,” for the area : the dunes have been consolidated 
with little alteration to their contours. Incidentally, it may be
