cxiv PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY 



SCIENTIFIC COMMITTEE. 



May 5, 1914. 



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



members present. 



Pelargonium hybrids. — Mr. J. Fraser, F.L.S., continued his remarks 

 upon Pelargonium hybrids, deahng with those into whose composition 

 P. quercifolium had entered. The complete record of his examina- 

 tion of these forms will be published in the Journal of the Society 

 later on. 



Scale Insect on Furze. — The Rev. W. Wilks, V.M.H., exhibited a 

 branch of Furze thickly infested with a cottony-white insect looking 

 very much like a scale insect, and probably identical with Pseudococcus 

 ulmi, which has previously been recorded as attacking that plant. 



Malformed Rose. — Miss Collin sent from Surbiton a very curious 

 malformed Rose, which Mr. W. C. Worsdell, F.L.S., took for further 

 investigation {see p. cxvi). 



Beech with curious root growth. — A specimen of Beech came from 

 Mr. P. T. Godsal, of Iscoyd Park. The tree had been, it is supposed, 

 struck by lightning and partly killed; the upper hving portion had 

 sent out roots which had grown down, branching as they went, to the 

 ground, beneath the dead bark. This kind of growth is not infrequent 

 in Willows. 



" Fire " in Tulips. — Rev. Canon Fowler said that this season 

 the Tulips in his garden were remarkably free from '* fire," though 

 last season they had been badly diseased. Mr. F. J. Chittenden 

 said that plants in his garden exposed to wind had suffered badly, 

 but in the Tulip trial in the Wisley Garden scarcely any disease was 

 to be seen. There they had been protected by putting branches of 

 Broom between the beds. 



Schizanthus malformed. — A Schizanthtts in which the flowers had 

 apparently been displaced by vegetative shoots was received from 

 Mr. Crosswell, of Pickhurst Manor, Flayes, and referred to Mr. Worsdell 

 for further examination (see p. cxvi). 



Uncommon Plants. — Messrs. Perry exhibited Iris minuta with 

 narrow -petalled yellowish flowers about an inch across, native of 

 Japan, and Glaucidium palmatum, a beautiful Ranunculaceous plant, 

 with divided bracts on the single -flowered scapes, and a mauve flower, 

 about two inches in diameter, with yellow stamens, native of the same 

 country. 



Hippeastrum vittatum x H. calyptratum. — Mr. A. Worsley made the 

 following remarks concerning the hybrid Hippeastrum exhibited on 

 March 24 (see p. xHv) : " The Amarylleae genuinae form a tribe 

 distinguished from the Coronatae, on the one hand, and from the
