lxviii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



and were now in full bloom. As another instance of a late 

 recovery he mentioned an Ailanthus glandulosus, which sent up 

 suckers fifteen years after it had been cut down. 



Malformed Narcissi. — Rev. C. Wolley-Dod exhibited speci- 

 mens of different varieties of Narcissus, showing a constriction of 

 the mouth of the trumpet or " corona." It was suggested that it 

 might be due to some check or enfeeblement, since it was always 

 the later flowers which exhibited the peculiarity. An analogous 

 constriction in corollas sometimes occurs in flowers reverting to 

 self- fertilisation — as, e.g., in Gentiana Andrewsi. 



Excrescence on Willows. — Mr. Blandford exhibited a branch 

 with a tumour-like growth, 3 to 4 inches in diameter. They 

 appear to be common on Willows by the river Meuse. It was 

 suggested that a species of saw-fly might prove to be the cause. 

 Mr. MacLachlan undertook to report further upon it. 



Oak Wood Destroyed. — He also exhibited a piece of Oak com- 

 pletely converted into powder by attacks of Lyctus canaliculars. 

 It is a beetle which causes great mischief to gun-stocks in Birming- 

 ham. He also showed specimens of wood from barrels perforated 

 by Carpophilus hemipterus. In a previous case the staves were 

 perforated on both sides ; in the present instance the attack b^y 

 the insects was made after the barrels had been completed, as the 

 perforations only occurred on the exterior. 



Primrose Seedling. — Miss Woolward sent a new and remark- 

 able form of a Primrose which accidentally appeared in a cottage 

 garden at Belton, near Grantham. Its peculiarities consist in 

 the corolla lobes being red below and yellow above, as well as in 

 possessing a sweeter and more powerful perfume than most 

 varieties. 



Heterozcismal Fungi. — Dr. Plowright exhibited specimens of 

 Puccinia Digraphidis, Soppitt, on the leaves of Phalaris arundi- 

 nacea, which were found by Dr. D. Franzschel near Wiborg in 

 Finland, growing in the vicinity of ^Ecidium Convallariae ; also 

 specimens of Puccinia Agrostidis, Plow., on Agrostis vulgaris 

 collected by the same gentleman near Lewaschow, in Bussia, 

 growing in the vicinity of ^Ecidium Aquilegiae. He further stated 

 that he had this year produced the Caeoma Laricis upon Larch 

 by infecting this plant with the germinating teleutospores of 

 Melampsora betulina, the converse experiment of producing the 

 Melampsora on Birch from the spores of Casoma Laricis having
