Clxxvi PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Origanum species. — Mr. J. Fraser, F.L.S., showed specimens of 

 Origanum which he had been growing, and pointed out that some 

 confusion had apparently arisen with regard to the habit and duration 

 of some of the species. Mr. E. M. Holmes, F.L.S., who has given 

 particular attention to this genus, took some of the specimens for 

 further examination and report (see p. clxxviii). 



Two-podded Sweet Pea. — photograph of an inflorescence of Sweet 

 Pea was received, from which it was evident that one flower had pro- 

 duced two pods arising from distinct carpels. They both appeared to 

 occupy an anterior position, but this could not be certainly determined. 



Scientific Committee, October 6, 1914. 



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



members present. 



Hybrid Saxifrage. — Mr. J. Fraser, F.L.S., showed a hybrid Saxifrage 

 which had appeared in his garden, evidently a cross between 5. granu- 

 lata and one of the mossy Saxifrages, probably 5. Rhei. It produced 

 leaves in autumn somewhat intermediate between those of its putative 

 parents. The inflorescence is about 12 inches in height, and the white, 

 cup-shaped flowers are tinted with red. 



Sempervivum chrysanthum. — Mr. A. Worsley showed an inflorescence 

 of this plant, and remarked that apparently two forms are grown in 

 gardens under this name, one having lateral inflorescences only, the 

 other a large terminal inflorescence. 



Malformation in Pinus Thunbergii. — Mr. W. C. Worsdell, F.L.S., 

 exhibited a curious growth of this Pine from Sir Edmund Loder's 

 garden at Leonardslea, in which the normal foliage spurs were re- 

 placed by recurved fleshy scale leaves, and in some cases by a pair, 

 probably homologous with the paired ovuliferous scales of the Pine 

 cone. Here and there an abortive female cone occurred. A fungus 

 was present in all parts of the shoot, and this had probably induced 

 the malformation. 



Black Apple. — Mr. L A. Walker, of Woodberry, Sydenham Hill, 

 S.E., sent a perfectly black apple. Only once before has an Apple 

 having this appearance been shown before the Committee, and on that 

 occasion Dr. M. C. Cooke attributed the appearance to an attack of 

 the fungus Sclerotinia fructigena ( = Monilia fructigena), the cause of 

 brown rot of various fruits. 



Scientific Committee, October 20, 1914. 



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

 members present. 



Lachnus viminalis. — Mr. J. Fraser showed specimens of this very 

 large species of aphis, which attacks various Willows and is very 

 destructive to them.
