Citrus Fruits, The Cause of Stem-end Rot of. By H. S. 



Fawcett {Phytopathology, ii. p. 109 ; June 1912 ; 2 plates).— Dark 

 brown, reddish-brown, or black discoloration appears about the base 

 of the fruit, which has usually fallen previously. The rotting often 

 proceeds after packing. The fungus causing the rot is a new species 

 named Phomopsis citri, and has been isolated and infection experi- 

 ments carried out with it. — F. J. C. 



Citrus Scab. By H. S. Fawcett (U.S.A. Exp. Stn., Florida, 

 Bull. 109 ; May 1912). — Citrus scab is caused by Cladosporium citri. 

 It attacks sour oranges and lemons badly, but only disfigures tangerines, 

 grape-fruit, and rarely sweet orange. 



It can be prevented by removing all sour orange or lemon sprouts, 

 by pruning all scabby young growth, and by spraying with ammoniacal 

 copper carbonate in bad attacks. — D. M. C.

Coffee. By T. B. McClelland (U.S.A. Exp. Stn., Porto Rico, 

 Ann. Rep., 1911, pp. 28-30). — As coffee seed does not long keep its 

 viability, experiments were made to see if it might be longer preserved 

 by excluding the moist air of the tropics. The conclusions arrived at 

 were that the viability of coffee seed is destroyed by very severe drying, 

 and that a certain amount of moisture as yet undetermined is necessary 

 for its prolongation. — A. P.
