CXXX PEOCEEDIXGS OF THE ROYAL HORTICULTUEAL SOCIETY. 



Italy ; and Plnjllosticta Lilii, on Lilium superhum, is at present confined 

 to Canada. There is an allied parasite, with some technical difierences, 

 called Cylindrosi)oriiLm incoiispicuum, found on leaves of the Martagon 

 Lily, but at present confined to Switzerland. Altogether, this report 

 should give courage to the English cultivator of Lilies, inasmuch as the 

 ' Lily disease ' so called, associated with Botrytis, is the only one which 

 need cause anxiety." 



Rev. W. Wilks observed that the best remedy for Botrytis was to 

 shake the diseased Lily bulbs in a bag of sulphur and then to replace 

 them in the ground, but not too deeply. 



Lily Hybrids. — ]\Ir. Bowles exhibited blossoms of L. Dalhansoni, the 

 result of L. dalmatic imi x Hansoni, to sbow the difference in colouring. 



Hybrid Passion- Flmuers. — Dr. J. H. Wilson, St. Andrews, sent 

 sjiecimens (both leaves and flowers) of a hybrid Passion-Flower, men- 

 tioned on p. 16G of the Hybrid Conference Report ; viz., P. ' Constance 

 Elliot ' X P. alba. The plant grows in an extraordinarily luxuriant fashion, 

 flowers profusely, and produces numerous yellow, seedless fruits. The 

 leaves are either five-lobed or three-lobed, the latter being in the minority. 

 He believes this Passion-Flower to be a new form, and a first-rate garden 

 acr[uisition. No steps have been taken yet towards distribution. 



He also sent specimens of the reciprocal cross referred to on p. 159 of 

 the Report. It bears a close resemblance to the above, but the leaves 

 with three lobes are in the majority, and the styles are not purple. 



Tuberose Diseased. — Some specimens were received from Mr. C. Maers, 

 Hockley, Essex, upon which ])r. M. C. Cooke reports as follows: — "In 

 the decayed crown of the corm I find no mycelium, or evidence that the 

 decay was caused in the first instance by fungus ; but plenty of insects 

 were present." Dr. Masters observed that such decay was usually at the 

 base, not at the apex, of the corm, as in the present instance. 



Carnations Diseased. — Mr. G. Roberts, of Exton Park, sent some 

 plants which were in a failing condition. Dr. M. C. Cooke examined 

 them, and reports as follows : — " The Carnations evidently sufiered in 

 the first instance from worm at the roots ; afterwards, when the foliage 

 was failing, they became attacked by the Carnation mould Heterosporiiim 

 cchinulatuDL (figured in Gard. CJiron., August 21, 1886, fig. 50). It is 

 doubtful whether these particular black moulds will attack healthy and 

 ^igorous plants ; but when they are weak, sickly, or injured, they then 

 become a ready prey." 



Apple-stems attached by Caterpillars. — Specimens were sent by Mr. 

 W. Camm, from Battle Abbey, upon which Mr. Saunders reports as 

 follows : — 



" The Apple-stems are, I should say, undoubtedly bored by caterpillars 

 of the ' Wood Leopard-Moth ' Zeuzera cesculi. The entrance to the 

 gallery may be easily found by examining the tree, and if moisture is 

 seen to be exuding from any part, mixed with sawdust-like particles of 

 wood, there the hole will be found ; a sharp-pointed wire should then be 

 passed in as far as possible, so as to stab the caterpillar. If this cannot 

 be accomplished, the entrance should be somewhat enlarged, and some 

 tow or cotton-wool steeped in tar or paraffin oil should be pushed in as 

 far as possible so as to stifle the insect. When no more can be got in,
