 Actinidia in Japan snc^fjests that native h^-ahty of }J[rai)e mildew 

 disease in ihc ( )ri(.ni ( Monogr. Erisiph. 1900, p. loi ), but Hara 

 considers there is evidently a considerable morphological tlififer- 

 ence between this and the typical U. nccaior, the former being 

 characterized by short, stout, subrigid appendages, with rli'^tinct 

 swollen bases, and by typically bcakless asci.

Notes: The diseases of jute have not yet been well studied by 

 pathologists even though the plant is so important as a source 

 of textile fiber. Sawada states that this dieback disease is one 

 of tjie most devastating jute diseases in'Formosa and the annual 

 loss is sometimes recorded as 30-40 '^y of the total crop. The 

 only remedy for this is said to be to avoid an insufficient supply 

 of potash in the soil, and Bordeaux mixture was shown to be no 

 protection against the disease.
