SCIENTIFIC COMMITTEE, JULY 20. 



cxix 



last year (see Journal E.H.S., vol. xxxiv., p. cxii.). This is now the 

 third year in which the plants have borne similarly modified flowers. 



Large flower in Apple. — Mr. Pickering, F.R.S., enquired whether 

 anyone had noticed flowers of apples with very numerous petals. He 

 had seen this season in the case of ' Bramley's Seedling ' a single flower 

 (the only one on the shoot) which though showing no sign of synanthy, 

 bore twenty-five petals, the stamens and other organs being well 

 developed. 



Helianthemum sporting. — Messrs. Barr sent an interesting sport of 

 Helianthemum ' Golden Ball,' a yellow variety, bearing branches 

 producing double scarlet flowers in the upper part of the plant. 



Nomenclature of multigeneric hybrids. — The secretary read the report 

 of the sub-committee upon the nomenclature of multigeneric hybrids, 

 the committee approving the recommendations contained therein. After 

 being read to the Orchid Committee, it will be presented to the Council 

 for its approval. 



Certificate of Appreciation. — A Certificate of Appreciation was 

 recommended to be awarded to Mrs. Scott-Elliott, of Teviot Lodge, 

 Hawick, N.B., for work in connection with the hybridizing of Aquilegias. 



Scientific Committee, July 20, 1909. 



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

 members present. 



Water Lilies dying. — Mr. Saunders, F.L.S., reported that he had 

 examined the dead water lily rhizome shown at the last meeting, and had 

 failed to find any organism present which would account for the death 

 of the plants. He considered the water in which they were growing very 

 foul. Some further material was referred to Mr. Saunders. 



Galls on Bhododendron. — Galls similar to those frequently seen on 

 B. ferrugineum, caused by the fungus Exobasidium rhododendri, were 

 exhibited on behalf of Mr. Veitch on Bhododendron Wilsonianum. The 

 occurrence of these galls in succeeding years may be materially lessened by 

 their removal before they acquire the white bloom which marks the time 

 of spore formation. 



Late- flowering Bhododendron. — Sir J. T. D. Llewelyn made some 

 remarks upon a Rhododendron now flowering at Wisley, which he con- 

 sidered to be a hybrid of B. Auchlandii or B. Fortunei. The bush 

 always flowers at this season, and bears bunches of white flowers on long 

 viscous peduncles subtended by deciduous bracts. 



Malformed flower in Lilium auratum. — Mr. Shea showed a flower of 

 this species which for the third year in succession produced very narrow 

 perianth segments, which were green. The plant was very strong, but all 

 the flowers were of this type. 



Sweet Pea stripe. — Mr. Shea also showed specimens of sweet peas 

 with the "stripe " disease, the cause of which is unknown. 



Sweet Pea double. — Mr. Chittenden, F.L.S., showed a flower of 

 sweet pea with three standards, the only one of the kind on the plant.
