REMARKS. According to SYDOW'S Monographia Uredinearum, the species of 

 Puccinia parasitic on Anemone are ten in number ; three of them have compact 

 teleutosori, while the other species have powdery sori. In our country, there are 

 six species of Puccinia on Anemone, all of which have the powdery teleutosori. 

 Among them Puccinia japonica is the only species which is provided with smooth 

 epispore. The fungus under consideration is the only species that has hitherto 

 been recorded MS growing on our Anemone. 



The fungus was described by DIETEL (3) from the specimen collected by 

 KUSANO in Tokyo. Naked, powdery and chestnut-brown teleutosori are scattered 

 or confluent in a large irregular mass on both surfaces of the leaf, mostly on the 

 under surface and on the petiole. Teleutospores are fusiform, clavate or oblong- 

 clavate in shape, attenuated at both ends or rounded at the base, not or slightly 

 constricted at the septum, smooth and chestnut- brown in colour, measuring 32 53 

 X14.5 23/i. The germ-pore of the upper cell is at the apex, and that of the 

 lower is located near the septum, provided with subhyaline or hyaline papilla. 

 Pedicels are hyaline, short or sometimes attaining to 35/x and subdeciduous. 

 jEcidia are often intermixed among the sori.
