286 ON THE LIFE-HISTORY OF PUCCINIA CORONATA, VAR. HIMALAYENSIS. 
With regard to (c), Gymnosporangium still remains alone, so far as I am aware, іп 
having more than one germ-pore to each cell of the teleutospore. | . 
With regard to (d), the absence of uredospores, this peculiarity is of course not rare, 
and I have noted a remarkably striking instance in Uromyces Cunninghamianus (Linn. 
Trans. ante, p. 141). : 
With regard to (e) the subject of this paper shows that it also is not peculiar to 
Gymnosporangium. . 
Thus, of all the peculiarities I have noted, the plurality of germ-pores is alone entirely 
peculiar to Gymnosporangium.
