NOTES ON UROMYCES AMYGDALI, COOKE, 
quite a variety of fruits here to which they were formerly 
strangers. 
As might be anticipated, this fungus has its peculiarities of 
attack. In nry own garden, for instance, the peach and plum 
trees were badly affected, while an apricot whose branches inter- 
laced with an affected peach tree had not a speck upon it. In 
the Royal Horticultural Gardens, Burnley, apricot and almond 
trees are as yet unaffected, and in 1890-91 not even plums were 
attacked, only peaches. J. G. O. Tepper, of Adelaide, informs 
me that in his garden the apricots are very badly affected year 
after year, peaches to a slightly less extent, and a plum tree with 
the branches touching other diseased trees is wholly unaffected. 
In contrast to this, there is the case already mentioned where the 
peach trees were unaffected and the plum trees more or less 
attacked. No doubt the variety of the respective trees will have 
an important influence on the immunity from or liability to 
disease. 
Varieties most Affected. 
In the Royal Horticultural Gardens, Burnley, where so many 
different varieties are grown, I was able, with the assistance of 
Mr. Neilson, to select some of those most affected. Kerr's Slip- 
stone, Royal George and Crimson George are very liable among 
peaches, and Darwin and Dante among nectarines. Seedling 
peaches are also badly attacked. 
Plums such as Late Harvey and Imperial Ottoman were pretty 
bad, and it was very noticeable that all those provided with 
thorns, such as the French Cherry Plum, seemed to enjoy com- 
parative immunity from the disease. 
Distribution. 
This disease has a very wide distribution, possibly co extensive 
with the cultivation of the peach and allied fruits. It has actually 
been found in Britain, France, Germany, Italy, Austria, Belgium, 
Switzerland, North America, Canary Islands, India, Cape Colony 
and Australia. As regards its local distribution in Victoria, it 
extends from the Murray to the sea— from Rutherglen in the 
north to Warrnambool in the south.
