MORRIS: "The Coffee Leaf Disease of Ceylon and 

 Southern India." 



Hemileia Canthii, Berk, and Broome, which infects 

 Plectronia campanulata, a wild plant in Ceylon, and 

 Hemileia Woodii, Kalchbr. and Cooke, which occurs on a 

 plant allied to coffee in Natal, are very closely allied to 

 Hemileia vastatrix, and are considered by some as being 

 identical with it. 



USTILAGINE^E. 



USTILAGO SACCHARI, RABENH. 

 (Sugar Cane Brand). 



In Java this fungus has been reported to do serious 

 damage to the sugar cane. Mr. O. W. Barrett has observed 

 it in Trinidad, where, however, it appeared to be limited 

 to one or two plantations, and the extent of the damage 

 done seemed to be of a less serious nature. 



The leaves are the parts affected, and more especially 

 the younger ones which have not yet separated from each 

 other. The whole of these upper leaves is converted into 

 a discoloured, projecting structure. From the upper part 

 of the affected cane, as a rule, no secondary shoots arise, 

 and those which arise from the lower part become in- 

 fected in their turn. The discoloured whip-like structure 

 at the end of an attacked cane becomes dusty black and 

 contains the spores of the fungus. 



Care should be taken to burn all diseased plants as 

 soon as they are attacked. Cuttings should not be taken 

 from diseased plants. Soaking the cuttings in Bordeaux 

 mixture for six hours or more before planting should 

 prove efficacious in diminishing the spread of the disease. 



Diagnosis : Spore-mass black, spores globose or 

 angularly globose, 8-18 microns diam., olive brown or 

 rufous, epispore thick, smooth.
