recognised by the dark brown almost black appearance in contrast 
to the rusty-brown pustules containing uredospores alone. 
Nectarine. — On the leaves of a nectarine (Dante) from the 
Royal Horticultural Gardens teleutospores were found, agreeing 
closely with those on peach (fig. 6) as well as on the variety called 
Darwin. 
Plum. — On plum leaves from the Gardens, only comparatively 
few uredospores were found, while teleutospores were plentiful 
(fig- 7). 
A specimen of plum leaf with rust upon it, plucked on May 
19th, was sent from Hobart by Mr. Rodway, and both uredospores 
and teleutospores were found upon it (fig. 8). 
Apricot. — The rust on the apricot leaf is still comparatively 
rare in Victoria. I am indebted for specimens to an indefatigable 
worker, Mr. G. H. Robinson, of Ardmona, who sent them as far 
back as June 23rd, 1894. The teleutospores were not numerous 
among the uredospores, and one is shown in fig. 9. 
In Mr. Tepper's specimen on the fruit forwarded early in 
January, only uredospores were found ('fig. 10). The skin of the 
apricot had small yellowish to brownish blotches over it, and the 
uredospores are seen to be of the normal type, but sometimes 
rather elongated, even attaining a length of 44 ^. On the other 
hand, they are sometimes excessively shortened, and the extremes 
of length, 26 to 44 p, were met with in this one specimen. They 
are, however, in relatively small quantity, and I am inclined to 
think that the close-set, downy hairs interfered with their proper 
development. When a microscopic section of the skin is made, 
only a few uredospores are seen with difficulty among the hairs, 
attached to the matrix. 
Almond. — As in the case of the apricot, the fungus is also very 
scarce as yet on the almond in Victoria, On June 17th of last 
year, Mr. Robinson found at Ardmona only a few leaves, and each 
with one pustule containing uredospores which are shown in fig. 11. 
I had also specimens from Netherby in December, 1893, and 
the undersurface of the leaves had quite a rusty appearance, owing
