Rem.VRKS. Tliere are three species of I'uccinia known at present to be 

 parasitic on Pollinia. They are Piiccinia Enlaliic, P. Pollinicc and /'. 

 icstivalis. 



Pucciuia EulaliiC and P. (CStivalis have alrcad}' been found in our 

 country and the urcdospores and paraphyses differ entirely from those of 

 this species. Now, when comparing the present species to Piiccinia Polli- 

 niiC, I noticed two ]5oints of difference between them, (i) Our species has 

 numerous germ-pores while they are three in the case of Pucciuia Polliniic. 

 (2) Paraphyses are irregularly bent in our species, while they are capitate 

 in Pucciuia Polliniic. I shall call this species provisionally imder the present 

 name imtil its teleutospores will be found. 



7. Uredo inflexa S. Its. n. sp.— (PI. XII. Fig. 12). 



Urcclosoi-i, hypoiihyllous ; minute, roundish or oblong, on discolored 

 spots, scattered or subgregarious, sometimes confluent, naked, puherulent, 

 brownish yellow. Uredospores, broadly ellipsoidal, subglobose or piriform, 

 echinulate, 28-40x20-26//; paraphyses numerous, curved, clavatc, light 

 yellowish, 40-45 x 5-9«.

Remarks. Among the description of the uredosori of many Puccinia 

 on Bambuseae, that of Piiccin'a mclanoccphala Syd., of India approaches 

 most closely to the present Uredo. But as our species is still lacking its 

 tcleutostage, the exact identification can hardly be made. But the uredosori 

 are amphigcnous in the Indian species, while they are all hypophyllous in 

 ours. The epispore is a little' thinner in our species. The jiaraphyses are 

 curved in ours. I shall call the fungus under consideration by the present 

 name, until its other stages will be found.
