bearing both entire and spinescent leaves, proving that they were not 

 different species, as some had supposed. The Holly is not infrequently 

 similarly dimorphic. 



Scientific Committee, May 17, 1904. 

 Mr. Michael, F.L.S., in the Chair, and seven members present. 



Buttercup fasciated. — Dr. Cooke exhibited a specimen of this pecu- 

 liarity. 



Nerine proliferous. — Mr. Worsdell, F.L.S., reported on some speci- 

 mens sent by Mr. Jackson : — " It is a case of germination of bulbiferous 

 seeds, as has been described in other Amaryllises. The seed becomes so 

 swollen and fleshy that a differentiation intp endosperm and integuments 

 can scarcely if at all be made ; while the ovary falls away from around 

 the seeds, leaving them exposed. Imbedded in the seed is a cotyledonary 

 sucker, while at the other end the cotyledonary sheath forms a bulbil 

 from which a new plant is developed." 



Fasciated Stem with a multifold flower of Narcissus. — Mr. Hawkins 

 sent a specimen, the stem showing a flower with seven times the usual 

 number of parts. 



Double Cherry with Caterpillar. — Mr. Saunders, F.L.S., reported upon 

 specimens received from Miss Verner, Bournemouth : — " The caterpillars 

 infesting the buds of the double Cherry are those of a small moth, one of 

 the Tortrices, I believe Penthina cynosbatella ; but without rearing the 

 moth I cannot be quite sure, as these little caterpillars are often so much 

 alike that it is impossible to be certain as to which species they belong. 

 Spraying the tree with a solution of paraffin emulsion, ' Abol,' ' Paranaph,' 

 or any insecticide which contains paraffin and soft-soap, is a good remedy ; 

 even plain water with a little soft-soap in it would be useful." 



Tulips diseased. — Mr. Massee, V.M.H., reported on plants brought by 

 Mr. Holmes : — " The Tulip bulbs are attacked by Botrytis vulgaris. 

 Numerous sclerota are present, imbedded in the bulb-scales ; hence it 

 would not be advisable to again plant those from the same patch of 

 ground that even appear to be sound." 



Pears diseased. — Dr. Cooke reported upon some fruit sent by Mr. 

 Rogers, Launceston :— " I have no doubt that the disease is the 1 Black 

 Spot,' Fusicladium. See Journal R.H.S. xxviii. p. 14. It is in an 

 undeveloped state as yet, no hyphae or sporules being present. It is very 

 common on Pears this year. In early spring it is recommended to spray 

 with a solution of sulphate of iron, and later on with Bordeaux mixture, 

 of a strength not to kill the Pears. It is a common error to use the 

 solutions of the sulphates upon the young and tender foliage of too great 

 a strength."
