SCIENTIFIC COMMITTEE, AUGUST 30. 



CXIX 



of several of the same raising, all of which showed the same charac- 

 teristics and colouring. The habit of the plant was intermediate 

 between the two parents. Inflorescence not short and curved as in 

 Cochlioda Noezlima, but slender and elongated (about 2 feet 6 inches) 

 as in Oncidium incurvum. Flowers about 1 inch across. Sepals and 

 petals light mauve, lanceolate, nearly equal, somewhat reflexed. Lip 

 three-lobed, constricted in the middle between the front and side lobes, 

 pale rose. Crest toothed or spiny, yellow. It is curious that the purple 

 colour in the flowers of 0. incurvum has obliterated the orange-red of 

 Cochlioda Noezliana. A Certificate of Appreciation to Messrs. Charles- 

 worth was recommended. 



Rhododendron ponticum. — Mr. Bowles showed a terminal bud of 

 Rhododendron ponticum, the leaves having petaloid coloration. 



Adventitious Root of Plane Tree. — Eev. W. Wilks sent an adven- 

 titious root of a Plane tree which he had found penetrating a straw 

 stake-band 6 feet from the ground. It was thought that the moisture 

 which had been held by the band had induced the formation of the root. 



Grapes. — A sample of Muscat Grapes was submitted from Colonel 

 Turnor, of Pinkney Park, which showed cracking and decay at the 

 point of union of berry and stalk, and the leaves were badly spotted. It 

 was agreed that the defects were due to too low a temperature in the 

 house, with insufficient ventilation. 



Decayed Monthretia Foliage. — Some Montbretias, Irises, and 

 Gladioli having decayed foliage were sent by Mr. Edward Hall, of 

 Leamington Spa. The bulbs and corms were apparently in good health, 

 without traces of disease. Many similar specimens had been lately 

 received, but up to the present no explanation of the trouble was forth- 

 coming.
