SCIENTIFIC COMMITTEE. CXxi 



A Certificate of Appreciation was recommended to Mr. Smith 

 for his work with these Pelargoniums. 



Scientific Committee, August 12, 1913. 



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

 members present, with Mr. R. Farrer, a visitor. 



Agapanthus inapertus syn. A. Weilliglii Hort. — Mr. A. Worsley 

 showed a specimen of this beautiful species of Agapanthus, which he 

 had obtained irom Holland. It is fully described at p. 363. 



Double Cineraria. — Mr. Worsley also showed heads of a Cineraria 

 with proliferation similar to that seen in the ' Hen and Chickens ' 

 Daisies, but with the separate capitula more congested. He remarked 

 that this type of doubling often occurred in forms that normally 

 bear single flowers when they blossom in summer, as in the present 

 instance, and that the normal type would be resumed later on. 



Saxijraga florulenta. — This curious species of Saxifraga was sent 

 by Mr. Chaplin, of Great Amwell, Ware, in whose garden it had 

 flowered. It was collected by him and had apparently been growing 

 in shade in cultivation, though it appears to grow alike in sun and 

 shade in its home in the Maritime Alps, where it occurs at high 

 altitudes. It has perhaps only once before flowered in this country, 

 when it was shown by Maw and received a first-class certificate in June 

 1872. Its foliage is more attractive than its flowers. 



Rubus discolor double-flowered. — Mr. Chittenden showed from a 

 correspondent at Haywards Heath a beautiful pink-flowered form of 

 the common bramble with double flowers. It had been found in a hedge 

 and was apparently wild. Several such forms are in cultivation. 



Xanthorrhoea australis. — Mr. E. M. Holmes, F.L.S., showed the 

 lower part of the leaf-rosette of this plant, which is now being imported 

 for cattle food on account of the sugar it contains. 



Aphis on Picea. — Some shoots of the Picea pungens glauca and 

 P. magnifica were sent from Lexden attacked by the large aphis which 

 has been so prevalent this year and last on these trees in several 

 parts of the country, and has worked great damage to them. Mr. 

 Chittenden said that several trees had been attacked at Wisley, 

 but the insects had all been killed by one thorough spraying with 

 " Niquas " in May, and the trees had quite regained their beauty. 

 The winter is passed in the egg stage, and spraying should be resorted 

 to as soon as the insects hatch out in spring, any wash containing 

 nicotine being useful. 



Apples showing Glassiness. — Some specimens of the apple ' Lord 

 Derby ' were sent from South Devon from some cordon trees, and 

 showed the curious phenomenon known as glassiness in a marked 

 manner. The cause leading to this peculiar condition is so far 

 unknown, though it is often attributed to frost. It is evident that
