SCIENTIFIC COMMITTEE. 



ll 



Fruit of Chimonanthus fragrans. — Mr. J. Eraser, F.L.S., showed a fruit of 

 the ' Winter Sweet ' ripened in this country. 



Various Plants. — Mr. Hay sent specimens of the following uncommon plants : 

 Antirrhinum Coulterianum and Lupinus Grayi, from California; Saxifraga 

 fimbriata, from the Himalaya ; a deep-coloured form of Impatiens Roylei ; 

 Meconopsis latifolia with incipient doubling. 



Scientific Committee, August 13, 1918. 

 Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and seven members present. 



Trigonella coerulea. — Mr. J. Fraser, F.L.S., showed a specimen of this plant, 

 which has a very persistent odour somewhat like that of curry. It is a native 

 of Southern Tyrol and Italy, and is said to be used for giving scent to cheese 

 and for spicing cattle cake. 



Doubling of Tropaeolum. — Col. H. E. Rawson showed some examples of 

 Tropaeolum with enations from the calyx adjacent to the spur, where petaloid 

 growths had been produced bearing an anther (or part of one) on their margins. 

 He considered that this might be the beginning of the doubling of the flower. 

 Mr. E. J. Allard pointed out that there were two forms of double Tropaeolums 

 arising from different kinds of multiplication of parts. 



Plants from Palestine. — Mr. J. W. Odell showed examples of Marrubium 

 vulgare, Verbascum Blattaria, and a species of Nigella raised from seed sent from 

 Palestine. The last was not recognized, and Dr. Rendle took it for further 

 examination. 



Rubus sp. — Mr. Bowles showed a species of Rubus, a chance seedling in his 

 garden, and probably of Chinese origin, with palmate leaves, v/hite tomentose 

 beneath, and drooping clusters of large black fruits. Dr. Rendle also took this 

 for further examination. 



Damage by Hail. — The Rev. W. Wilks showed a specimen of Vitis with the 

 foliage perforated by hailstones in a recent storm at Shirley, and the stem with 

 large warts resulting from damage from the same agency. 



Scientific Committee, August 27, 1918. 

 Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and three members present. 



Atropa Belladonna. — Leaves were sent by the Leinster Herb Association 

 showing perforation, these were referred to Mr. A. D. Cotton. 



Apple Rot. — Fruit sent by Mrs. J. D. Crosfield showed Sclerotium pyrinum 

 in various stages. 



t A Certificate of Appreciation was unanimously recommended to Mr. C. J. 

 Lucas of Warnham Court for his work in raising Odontoglossum x ' Joy ' (Uro- 

 Skinneri x eximium). 



Scientific Committee, September io, 1918. 

 Mr. E. A. Bowles, M.A., V.M.H., in the Chair, and four members present. 



Perforated leaves of Atropa. — Mr. A. D. Cotton, F.L.S., reported that he 

 found no fungus on the leaves referred to him, but considered the trouble was 

 probably due to a biting insect which search would most likely reveal. 



Potato Wart Disease (Synchytrium endobioticum) . — Mr. F. J. Frogbrook 

 attended and exhibited Potatos affected with wart disease. It was pointed 

 out by the Committee that the disease was notifiable, and every effort should be 

 made to destroy the affected tubers on the Leyton Allotments, where the outbreak 

 had occurred. 



Fasciated Maize. — Mr. A. T. Johnson exhibited a spike of Maize showing 

 fasciation with male and female parts reversed. A similar exhibit also came 

 from Mr. J. Fraser. 



Pseudolarix Kaempferi. — A fruiting branch of this Larch, taken from the 

 original imported plant, was sent by Mr. G. Paul. The specimen was well 

 covered with small, green, Artichoke-like cones. 



Lycium chinense. — Mr. J. W. Odell showed a branch of this Chinese Box 

 Thorn bearing numbers of coral fruits. It was grown in the London area, and 

 was considered by the Committee to be the variety megistocarpum. 



Potato Scab. — Mr. H. P. Betts showed tubers with this disease.
