 However, according to him, there are transitional forms between these two

Lately, W. Tranzchel (2) proved the genetic relation of the present 

 species by infection experiments to /T£:idiuin Plantaginis on P'lantago 

 lanccolata in Russia. At about same time, Fr. Bubak (i) also obtained the 

 similar results, but he failed to prove the relationship of the /Ecidia on 

 Plantago major, P. vu-dia, P. Cynops and P. Psylluin witli this species. 

 /Ecidium Plantaginis on Plantago major occurs very commonly in our 

 country, but yEcidium on Plantago lanccolata is not yet found. 



In 1908, Dietel(i2) described this fungus sent from Japan as a new 

 species under the name of Pnccinia varians. His description correspond 

 closely that of Pnccinia Cvuodontis, but he did not give any remarks on the 

 affinity with the latter species.
