differ not only from those of Puccinia graminis, but from those 
of all other European species. 
From this account, then, it is extremely probable that the 
Mcidium of the berberry enters into the cycle of existence of 
Puccinia graminis, and, if this be true, wherefore should not 
other species of Puccinia be related in like manner to other 
Aicidia? This is the conclusion to which many have arrived, 
and, taking advantage of certain presumptions, have, we fear, 
rashly associated many such forms together without substantial 
evidence. On the leaves of the primrose we have commonly a 
species of Aicidium, Puccinia, and Uromyces nearly at the same 
time; we may imagine that all these belong to one cycle, but 
it has not yet been proved. Again, Uromyces cacalie, Unger, 
Uredo cacalig, Unger, and Aicidium cacali@, Thumen, are con- 
sidered by: Heufler* to form one cycle. Numerous others are 
given by Fuckel,f and De Bary, in the same memoir from which 
we have already cited, notes Uromyces appendiculatus, Link., 
U. phaseolorum, Tul., and Puccinia tragopogonis, Ca., as possessing 
five kinds of reproductive organs. Towards the end of the year, 
shortly stipitate spores appear on their stroma, which do not fall 
off. These spores, which do not germinate till after a shorter or 
longer winter rest, may conveniently be called resting spores, or, 
as De Bary calls them, teleutospores, being the last which are 
produced. These at length germinate, become articulated, and 
produce ovate or kidney-shaped spores, which in their turn 
germinate, penetrating the cuticle of the mother plant, avoiding 
the stomates or apertures by which it breathes. After about 
two or three weeks, the mycelium, which has ramified among the 
Berne by Shuttleworth in 1833. It is named by him Acidium graveolens, and 
differs in the following particulars from Acidiwn berberidis. The peridia are 
scattered as in #. Epilobii, and not collected in clusters. They are not so 
‘much elongated. The cells are larger, and the orange spores nearly twice the 
diameter. There is a decided, strong, but unpleasant odour in the fresh plant ; 
hence the name. ‘The above figures (figs. 107, 108). of the cells and spores of 
both species are drawn by camera, lucida to the same scale—380 diameters. .
