Xl PEOCEEDINGS OF THE KOYAL HORTICULTURAL SOCIETY. 



Scientific Committee, April 19, 1910. 



Mr. E. A. Bowles, M.A., F.L.S., F.E.S., in the Chair, and ten 

 members present. 



The late Mr. G. S. Saunders. — The members heard with deep regret 

 of the death of Mr. G. S. Saunders, F.L.S., who had for many years 

 been a regular attendant at the meetings of the Committee, and who 

 had acted as entomological referee. It was resolved that a vote of 

 condolence should be conveyed to Mr. Saunders's relatives, the reso- 

 lution being carried by the members in silence, upstanding in their 

 places. 



A four-merous Narcissus. — Mr. Chittenden, F.L.S., showed on 

 behalf of Mr. Murray Thompson, a flower of Narcissus ' Sir Watkin,' 

 having eight perianth pieces, eight stamens, and a four-celled ovary 

 with four-lobed stigma. The multiplication of parts in Narcissus flowers 

 is frequent, but this specimen showed the multiplication very regularly. 



Infertile Cineraria. — Mr. Worsley drew attention to a blue-flowered 

 Cineraria which he found among others in his garden with the stamens 

 developed, but containing no pollen. 



Intermittent variegation.— Mr. Bowles read a communication from 

 Canon Ellacombe concerning variegation in Sedum Telephium . This plant 

 had produced leaves variegated with pink in Canon Ellacombe's garden 

 in 1908, and a piece of the plant was placed in Mr. Bowles' garden, 

 where, also, it was variegated. In 1909, how^ever, in hotJi gardens the 

 shoots were wholly green, but this year again, in both gardens, they 

 were coming variegated. Other examples of intermittent variegation 

 were mentioned, most occurring when the plant in question had been 

 placed under different conditions from that in which it generally grew, 

 and it was considered that variegation depended largely upon the 

 environm.ental conditions acting upon the plant, as well as on an innate 

 tendency to produce variegated foliage.
