no Junif'cnis chincnsis was found in the vicinity. After careful 

 examination, liara found J. littoralis growing wi'd in the region 

 which carried tclia looking quite different from those of /. chi- 

 ncnsis. Inoculation, using type material colected by Watanabe, 

 proved that this telial form infects P. sinriisis very easily, hut P. 

 aiicitparia {Sorhus oiicuparia, S. japonica) remained free (1. c. 

 6°: 751-75-)- tiara also suggested that the case reported by 

 Ideta, regarding tlie leaf-inhabiting form of Gyninosporaiininm 

 en J . rit/Ula as the pe:ir-rust organism, is one of misidentification 

 of the host, because J. littoralis is often mistaken for /. rig'.da (1.

* In looking over this synopsis. Prof. Miyabe kindly made the following 

 comments : 



(i) The plant here called Juniperus chincnsis var. procumbens should be 

 /. chinensis var. Sargenti, since /. procumbens, according to E. H. Wilson, 

 represents an entirely different plant. 



(2> The plant here called Juniperus littoralis is better called /. conferta. 

 in accordance with modern classification. 



(3^ The apple rust fungus probably had been existing in the prefecture 

 of Anmcri for centuries, where the wild crab apple is found common.
