received from Mr. B. G. Berry, F.R.H.S., Scarbutts Manor, 

 Boughton, Faversham, and submitted to Dr. William G. Smith, 

 who reports as follows : — " I cannot make up my mind whether 

 the fungus on Cherry leaves you sent last week is Cylindro- 

 sporium padi, Karst, or Cladosporium amygdalearum, Pass. 

 Both are given as causing spots on foliage similar to that sent. 

 The spores are different, but I get both forms (or something 

 very like them) present. In any case the fungus is the cause 

 of trouble. The disease is common in the United States, though 

 I have no definite record of its occurrence here. It is not con- 

 sidered serious, and yields easily to spraying remedies. I am 

 afraid at present the crop is too far advanced to allow of 

 immediate treatment, but as soon as it is plucked Bordeaux 

 Mixture should be sprayed on the foliage. Next year the spray- 

 ing should be continued as soon as the foliage is strong enough 

 to allow it. The preparation of Bordeaux Mixture and allied 

 fungicides I have already described in the ' Gardeners' Chronicle ' 

 last August. It should not be used towards the season of ripe 

 fruit, as it stains the Cherries, but applied before and after is 

 reliable." 



Black Currant x Gooseberry. — Mr. W. Culverwell, of Thorpe 

 Perrow, Bedale, sent a fruiting spray of this curious hybrid, 

 figured in the "Gardeners' Chronicle," September 3, 1892, p. 271, 

 showing well the resemblance to the manner of fruiting in the 

 Currant, though it was entirely without its scent. The fruit 

 resembled small Gooseberries, but the leaves had no spines. 



Four-merous Odontoglossum. — Mr. McBean sent a spray of 

 0. crispum, in which all the four blossoms upon it had the two 

 anterior petals adherent to the sepal between them, three points 

 indicating the fusion. In addition to the above, the sepals 

 fused with the petals were petaloid and the ovaries were aborted. 

 In two flowers it was S 2 , and in the other two, S 3 that was 

 petaloid. 



Tuberous Growth on Vine. — Dr. Masters exhibited a specimen 

 of an outgrowth not uncommonly met with on Vines ; similar 

 ones are occasionally associated with a multiplication of buds. 

 It is probably caused by a puncture of some insect, which sets 

 up a subsequent growth by hypertrophy. A similar outgrowth 

 is occasionally seen on Marechal Niel Koses.
