and it looks so rounded at the point of junction with the upper 
cell that one might readily mistake it for an independent, uni- 
cellular, stalked spore. 
It would appear, however, that on the continent of Europe the 
teleutospore form is the prevailing one, for De Bary k speaks of 
Puccinia pnuii belonging to the Micropuccinia, as teleutospores 
only are known. 
No doubt the absence of teleutospores helped to mislead Dr. 
Cooke in his determination, and such a case emphasises the 
necessity for continuous observation of many of these fungi on 
the spot, in order to determine accurately their affinities, for at 
certain seasons only the uredospores are present, as in this 
instance, or it may be that the teleutospores only are present as 
in the case of Puccinia burchardice determined by Dr. Saccardo 
where I had to supplement the description with that of the 
uredospores. f 
A few brief notes may now be given on each of the Victorian 
hosts mentioned, in order to show that it is the same fungus 
disease which affects them all. Puccinia prunt, Pers., has to be 
recorded as new to Victoria for the apricot. 
Peach. — Leaf -rust on the peach has been very prevalent this 
season, and yet the teleutospores are comparatively rare in the 
specimens which I have examined even in the month of July. A 
number of leaves were examined from peach trees in my own 
garden, but no teleutospores were found, only uredospores (fig. 6). 
In one instance the uredospore had germinated on the leaf still 
attached to the tree as shown in fig. 5. On some peach leaves 
from the Royal Horticultural Gardens, teleutospores were found, 
but not in great quantity, along with uredospores. I have just 
examined (July 3rd) some leaves from young trees of Bid well's 
Late, Improved China Flat, Red Ceylon, &c, and while there is 
abundance of uredospores there are no teleutospores The pustules 
containing teleutospores and uredospores mixed may be readily
