SCIENTIFIC COMMITTEE. 



September 8, 1914. 



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



members present. 



Insect on Bay Leaves. — Mr. E. M. Holmes, F.L.S., reported that the 

 Lecanium on the leaves of Bay was L. hesperidum Linn. = L. Lauri 

 Signoret. There seems no difference between the two, except that they 

 occur on different plants. 



Gall on Gerbera nov. spec. — Mr. W. C. Worsdell, F.L.S., showed a 

 leaf of a pink-flowered Gerbera from the Transvaal, with galls on the 

 veins. 



Pelargonium hybrid. — Mr. J. Eraser, E.L.S., showed living specimens 

 of a natural hybrid between P. denticulatum ' Stella ' (male parent) 

 and P. quercifolium minus (female parent). He exhibited dried speci- 

 mens of the parent forms. The crossing had been effected by bees. 



Pancratium canariense. — Mr. A. Worsley showed a " spike " from 

 one of the seedlings of this plant raised by him. He has also succeeded 

 in crossing the species with P. maritimum. 



Dahlia Stem Eaten by Wasps. — Mr. Holmes exhibited a piece of 

 stem, the fleshy cortical part of which, on one side, had been devoured 

 by the common wasp (Vespa vulgaris), specimens of which were 

 brought, showing them to be v/orkers, not drones. 



Papaver orientate x P. somniferum. — Mr. E. A. Bowles exhibited 

 a supposed hybrid plant of this nature from Mr. Perry's garden. Mr. 

 Perry had made a sowing of his white variety of P. orientate, amongst 

 which a few plants of P. somniferum and a few of the hybrid had 

 appeared, the majority coming true. The hybrid is infertile, and has 

 so far proved to be hardy. It is a perpetual flowerer. Evidence of the 

 presence of P. somniferum blood is found in the shiny, rather glaucous 

 character of the leaves. 



Rose Galls. — Mr. Bowles brought some small Rose galls from the 

 Alpes-Maritimes. 



Scientific Committee, September 22, 1914. 



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



members present. 



Sawfly on Viola. — Mr. Bowles said he had received a letter from 

 Mr. F. D. Morice, of Woking, concerning the sawfly larvae which he had 

 found feeding on Violet. He thought they were probably the larvae of 

 laxonus glabratus, a small purpHsh-black insect with red legs, which is 

 widely distributed, and does not feed exclusively on Violas.
