16 THE AUSTRALIAN NATURALIST. 
It must be understood that I am writing solely of a par- 
ticular district—the sandstone country embraced by French’s 
Forest and Kuringai Chase, the shale country being comprised 
‘in the ridge up the North Shore line to Asquith and patches 
on Berowra Creek, a district that has taken me nearly 3 years 
to work systematically. There is a lot yet to be accomplished 
from Hornsby right across to Parramatta, amd I appeal to 
members to assist and note the flowering periods of such species 
‘as acmeniodes, etc., to be found there. 
There is work for all on the eucalypts, more particularly 
for those Interested in the pollination of the flowers. 
This is a subject which will throw considerable light on 
supposed natural hybridisation, for it is my opinion that the 
eucalypt flower does not lend itself to outside pollination. The 
arrangement of the stamens seems to guard against any outside 
influence. :
