Remarks.— To settle the question whether the fungi attacking five 

 different host plants belonging to Vitaceie (Ampelopsis heterophylla, Par- 

 therweissus Iricuspidata, Vitis Goigmt'uv, Vitis jlvxuusa and Vitis v in if era) 

 are of the same species or not, careful comparison was made between them. 



They agree in main important points but with some minor variations 

 which may be briefly stated as follows: 



(1) As to the paraphyses in the uredosori, those on Amp. heterophylla 

 and Parth. tricuspidata well agree in that they are clavate, curved, some- 

 what inflated at the top, stout, 30-45// in length, while those on Vitis 

 Coignetim and V. vinifera, somewhat elongated, slender, curved, 40-60 u 

 long. (Compare Fig. 4, 5, and 6). 



(2) As to the uredospores there are following gradations :
