CCXXXVlll PEOCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



are on the lower (exposed) surface of the leaves instead of the upper 

 as in Drosera. 



Mistletoe on Pear. — Sir Harry Veitch, V.M.H., sent two branches 

 of Pear in which Mistletoe had been sown, to illustrate the difficulty- 

 experienced in getting the parasfte to establish itself on that tree. In 

 both cases the seed had germinated but the branches had died, and 

 they were typical of all the infections tried. 



Oncidioda x * Marjorie.' — Messrs. Oharlesworth sent a plant re- 

 sulting from a cross between Gochlioda Noezliana and Oncidium For- 

 hesii. Several crosses between members of these genera have now 

 flowered, and Messrs. Oharlesworth were awarded a Certificate of 

 Appreciation in 1910 in recognition of their work in demonstrating the 

 possibility of uniting these genera, which, although sufficiently distinct 

 morphologically, are evidently closely allied physiologically. 



Ivy leaves diseased. — Mr. Bowles showed foliage of Ivy from 

 Waltham Cross having numerous pale brown spots with a purplish 

 margin. 



Scientific Committee, December 3, 1912. 



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



members present. 



Prunus Miqueliana. — Mr. G. Wilson, F.L.S.. drew attention to 

 this beautiful shrub, which flowers in the open in December in Sussex 

 and elsewhere. Its appearance suggests a garden origin, for the 

 rosy flowers are semi-donble. 



Fern in bottle. — Mr. Fraser, F.L.S., showed a specimen of a Fern, 

 Cystopteris fragilis, growing in a bottle, in which it was found in a 

 garden. Though this Fern usually loses its leaves in July, the present 

 specimen was still green. 



Orange- fruited Holly. — Mr. Bowles showed orange-coloured fruits 

 from a Holly in his garden. The tree is probably identical with that 

 referred to in Dallmore's Holly, Yew, and Box under the name Ilex 

 Aquifolium fructu-aurantiaco . It is there suggested that this is a 

 seedling from the yellow-fruited variety, and the tree in Mr. Bowles's 

 garden is apparently of similar origin. 



Laelia pumila x Laelio-Cattleya x ' Ophir ' {Laelia xanthina x 

 Cattleya aiirea). — Mr. G. Wilson said this hybrid with cream-white 

 sepals and petals and purple labellum was raised by Mr. E. G. 

 Thwaites, of Streatham Hill, and was shown by him in support of his 

 hypothesis that white flowers are produced by a mixture of red, blue, 

 and yellow. 



Lychnis x Arkwrightii. — A Botanical Certificate was awarded to 

 this plant raised by Mr. J. S. Arkwright and exhibited by him on 

 July 16, 1912. The record of this certificate was inadvertently omitted 

 from the Minutes of that date.
