specimens of the Boronia serrulata, or native Rose, from the north shore, 
Port Jackson, the flowers of which, instead of having the normal rose- 
magenta colour, were of a pure white, a few having a very faint tinge 
of pink. A few days since, I had given to me a bunch of another 
beautiful species of Boronia (B. pinnata), growing to more than two 
feet high, and bearing a profusion of very fine and unusually large 
blossoms, some of a pure white, and others tinted with a very delicate 
shade of pink, the normal colour being a deep pink. These were gathered 
in the vicinity of Middle Harbour, Port Jackson. In the month of 
November, 1866, a “ Blueberry-tree” (Hleocarpus cyaneus), grow- 
ing on the grounds at Claremont, Rose Bay, near Sydney, the resi- 
dence of my friend George Thorne, Esq., produced flowers of a beautiful 
pink colour, instead of the usually delicate white. It would be interest- 
ing to observe whether a similar change takes place in the same tree 
the following year; if so, it may be considered an established variety. 
There is also a pink variety of more than one species of Eucalyptus, or 
Gum-tree, found in the interior of New South Wales, the normal 
colour of the flowers being white. Mr. James Norton, of Ecclesbourne, 
near Sydney, brought me a white variety of Sowerbea juncea, the usual 
colour being purplish, varying when fading to a reddish tinge. This 
gentleman, who has devoted some attention to the variation of the 
native plants in their wild state, gave me the following list of those 
which he has found white-flowering varieties or albinos :—

While travelling in New Zealand in 1861-2, I was much impressed 
with the following facts or convictions :—
