EEMAEKS. As mentioned above, in our country Anemone altaica is attacked by 



Puccinia cohaesa *var. japonica. Among the Herbarium specimens of our 

 i / 



University, I found another species of Puccinia on the same host-plant. Its 

 characters coincide exactly with those of P. singularis. The teleutosori of our 

 specimens are amphigenous, mostly hypophyllous and also on the petioles. They 

 are mostly arranged along the mid-rib of the leaf, as P. MAGNUS remarked in his 

 paper. Many small roundish sori are aggregated or confluent in large masses, 

 sometimes reaching 2 cm. or more in length, those on the petioles attain the 

 length of 4-5crn. They soon become naked, and are powdery and chestnut-brown 

 in colour. Teleutospores are ellipsoidal or oblong-clavate, rounded at both 

 ends, sometimes attenuated at the base, not or slightly constricted at the septum, 

 densely verruculose, sometimes smooth at the lower cell, and chestnut-brown in 

 colour, 32 58x19 30;*, (average size is about 42 x 23;*). Germ-pore of the 

 upper cell at or near the apex, that of the lower, at the middle or near the pedicel, 

 provided with a flattened or elevated hyaline or subhyaline papilla. Pedicels are 

 hyaline, deciduous and short, rarely attaining to 32;* in length.
