Xli 



Some grown on land heavily manured with sewerage matter 

 and ashes ; others on land which had not been manured for 

 several years, being a very light soil. They were attacked with 

 a species of Peronospora, allied to the Potato disease ; so 

 possibly a treatment similar to that for Potatos might be 

 advantageous. 



Tzdip with Axillary Flower, — Mr. Townell, of Heaton, 

 Newcastle-on-Tyne, sent a specimen of the Tulip ''Proserpine," 

 in which an additional small flower sprang from the axil of a 

 leaf on the scape. It is not a common production, but similar 

 growths occasionally occur. 



Cineraria Crosses. — Messrs. James & Son, of Farnham Royal, 

 sent several fine grown plants, which they had raised (1) 

 between Cineraria cruenta crossed with garden forms, and four 

 plants (2, 3, 4, 5), resulting from this ; also (1) again crossed 

 with C. Heritieri (6) ; also this last true species crossed with the 

 first named (1). It had white flowers, with pink tips to the 

 petals. Of the four plants, numbered 2, 3, 4, 5, No. 2 had 

 foliage more resembling that of C. cruenta, but 3, 4, and 5 that 

 of C. Heritieri, while three had a white ray and pink disk ; 5 

 had both ray and disk of a crimson colour. 



Scientific Committee, May 11, 1897. 



Dr. M. T. Masters, F.R.S., in the Chair, and seven members 



present. 



Weevils on Fruit Trees. — Mr. Rbt. Smith, of Shrewsbury, 

 forwarded some living specimens received by him from Mr. J. 

 Jones, Chelmick Pools, Church Stretton. They were described 

 as attacking Plum and Apple grafts, Roses and Raspberry buds 

 They proved to be Otiorrhynchus pisipes. The trees and bushes 

 might be sprayed, though a better plan is to shake the boughs 

 over a large sheet of paper, in which they can be caught and 

 then destroyed. 



Birch Branch with Phytoptus. — Dr. Masters showed speci- 

 mens illustrating the early stage of the attack on boughs by this 

 insect. It is not often the commencement of the so-called 

 " Witch Brooms " can be detected as in this instance. 



Abies bracteata. — He also exhibited sprays of this handsome
