xlvi PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Scientific Committee, April 13, 1915. 



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



present. 



Forms of Narcissus Tazetta. — Canon Fowler called attention to 

 two forms of Narcissus Tazetta which Messrs. Barr had exhibited, one 

 from a Spanish source, where it apparently grew wild, called N. Tazetta 

 canaliculars, with small yellow and orange-coloured flowers ; the 

 other, which had been found growing in an uncultivated place in 

 Wales, with larger, paler flowers, shown as N. ' Glandore.' The latter 

 had flowers of a tint and texture which suggested the possibility that 

 N. biflorus was one of the parents. 



Pelargonium Sport. — Mr. A. Worsley showed a sport of a bright 

 scarlet colour from the Pelargonium ' Double New Life.' Most of the 

 flowers in the truss were single and bright scarlet, but one or two were 

 double and cream, so far as the lower part of the flower was concerned 

 but single and scarlet so far as the dorsal petals went. The leaves 

 opposite the places of origin of the normal and " sporting " trusses 

 were apparently similar. 



Primula Reinii. — Mr. E. A. Jenkins showed a well-flowered plant 

 of this pretty and rare species, a native of Japan. It has recently 

 been introduced, and has mauve flowers of the corlusoides type, but 

 deciduous foliage more nearly approaching that of mollis, especially 

 later in the year. Mr. Jenkins was unable to state whence the plant 

 had come to him. 



Paeonia Delavayi. — Mr. Amos Perry exhibited this dark, small- 

 flowered Pseony, which resembles P. Moutan in growth, but has deeply- 

 divided leaves and somewhat pendulous flowers. It was introduced 

 by Mr. G. Forrest from Yunnan, where the Abbe Delavay collected 

 it in 1884, and described by Franchet in Bull. Soc. Bot. xxxiii. (1886), 

 p. 382. It appears to be hardy in this country and grows naturally 

 at an elevation of about 10,000 feet. 



Scientific Committee, April 27, 1915. 



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



members present. 



Roses with Crown Gall. — Mr. J. Fraser, F.L.S., showed some 

 specimens of Rose roots bearing typical spherical galls of about 1 inch 

 or rather more in diameter, produced by the attack of Bacillus 

 tumefaciens. 



Gall-like growths on Ribes &c. — Mr. W. C. Worsdell, F.L.S., showed 

 specimens of Ribes, Viburnum, and Symphoricarpos with large, gall- 

 like growths at intervals, caused by the development of numerous 

 adventitious roots which had grown out for some little distance, and 

 had then become checked. He stated on the authority of Mr. Geo. 

 Massee that the development of these gall-like masses of adventitious
