lxxxvi PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Variegated Daisy. — Mr. Worsley also showed plants of Bellis perennis 

 which had been cultivated apart from others for some years. When first 

 transplanted they were variegated, but in the fresh soil regained their 

 normal colour ; they have now again become variegated. It was remarked 

 that the variegation of plants appeared frequently to be due to the 

 presence of a certain "enzyme" or ferment in the cells, but the means 

 by which, and the conditions under which, this enzyme is produced do 

 not appear to be accurately known. 



Tritonia sp. nov. — Mr. Worsley also showed a plant which belongs 

 apparently to an undescribed species, and for which he suggests the name 

 of T. Clusiana. It appears to be nearly allied to T. securigera (—Mont-, 

 bretia securigera; = Gladiolus securiger), figured in the "Botanical 

 Magazine," t. 383, but " differs in having leaves twice as long and wide; 

 no obtuse or other indentation on the outer spathe valves, which are 

 longer than in Redoute's figure, while the flowers all face one way. The 

 plant was collected in the district of Greytown, South Africa, by Mr. 

 Layton, and was cultivated at Isleworth. It seems to form a link between 

 Tritonia and AntJiolyza, being hooded as in the latter genus. The 

 scentless flowers are produced in October from the new growth of 

 September. The plant is about one foot high." 



Diseased Timber-trees. — A portion of an oak branch attacked by Poria 

 vaporaria, and a specimen of the fungus of the beech (Polyporus 

 foment arms), were sent from Gerrard's Cross. It was recommended in 

 the latter case to cut out the fungus and dress the wounds with tar, and 

 to remove all fallen and dead timber as a means of checking the spread of 

 the disease. 



Scientific Committee, October 10, 1905. 



Dr. M. T. Masters, F.E.S., in the Chair, with twelve members present, 

 and Mr. Spencer Pickering, F.R.S., visitor. 



Asparagus plumosus fasciated. — M. O'Brien, V.M.H., showed a speci- 

 men of Asparagus plumosns fasciated and cristate, a peculiarity seldom 

 met with in this species, although common in A. officinalis. 



Cyrtanthus Bulbs, &c. — Mr. O'Brien also showed a bulb belonging to 

 the section Gastronema of Cyrtanthus, which had been kept dry through 

 the normal growing season. It had made an effort to grow by producing 

 small bulbs at the end of the stolons. He also showed flowers of Nerine 

 sarniensis syn. N. venusta and N. O'Bricni. 



Gourd Diseased. — Mr. Odell showed a variety of gourd which was 

 attacked by a fungus, which Mr. Massee, V.M.H., stated to be Glceosporium 

 sanguiuolcntmn, and which caused the appearance of numerous red 

 spots on the surface of the gourd. No other variety but this had been 

 attacked. 



Decaying Potatoes. — Mr. Veitcb, F.L.S., showed samples of potato 

 which had been dug early, and packed so that air could not freely circulate. 

 The outer part of each was quite rotten, and the decay was rapidly 

 spreading. It was thought that the potatoes when they were dug were
