CXCvi PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Exhibition of Fungi. — Mr. Douglas also suggested that it would be 

 advisable to hold an exhibition of fungi, displaying the edible and poisonous 

 species in separate collections, to be collected by the members of the com- 

 mittee or other persons interested in these plants. Rev. W. Wilks pro- 

 posed September 15, 1903, for the first exhibition. Dr. Cooke, V.M.H., 

 kindly promised to read a paper upon the subject at the General Meeting 

 of the Society on that day. 



Cactus Blistered. — Mr. Shea showed seedling plants with blistered 

 patches. Mr. Worsley observed that he was- familiar with the occurrence 

 for many years on old plants, but this appeared to be the first instance on 

 young plants. He had noticed flies on it, and thought that possibly they 

 might have been the initial cause of the mischief, the fungus following. 



Peach Mildewed. — Mr. E. Salmon sent a history of a Peach raised from 

 a stone, first in a pot, then in an unsuitable environment, and finally in 

 his garden, nine years ago. The one sent was attacked by the ordinary 

 Peach-mould. 



Lime-trees and Undergrowth. — A member inquired if there was any 

 truth in the belief that nothing will grow under Lime trees. It was 

 not generally accepted by the Committee ; but a Swede who was an 

 experienced gardener said that it was the common belief in Sweden that 

 such was the case (see page 667). 



Pine-bark and Coccus. — Mr. Saunders reports as follows on speci- 

 men sent to the last meeting by Mr. F. G. Lloyd : " As far as I could see 

 it was a different species from that which infests Beeches ; but as I was not 

 quite sure I sent specimens to Mr. Newstead, who replies as follows : ' 1 

 think the insect you sent me on Fir-bark is the Pine-aphis (Chermes Pini), 

 but I could not, unfortunately, extract an insect from the white sacs. 

 Could you send me a further and plentiful supply in order that I may 

 make quite sure of the insect ? ' It is pretty certain that Mr. Newstead 

 thinks it is a different species from that on the Beech, for he suggests that 

 it is a Chermes, whereas the other species is a Pseudococcus." 



Ipomoza rubro-ccerulca. — Mr. Worsley showed a blossom of this 

 plant, observing that it has been described as being at first red, then blue, 

 but in his experience this order was reversed, as it opens a deep blue, and 

 then becomes of a crimson tint. 



Arctotis, sp. — Mr. Worsley also showed specimens of A, arborcscens t 

 ' Jacquin ' (white), and A. Lcichtliniana (yellow). The former species was 

 the first to be introduced from South Africa ; it is commonly called the 

 South African Daisy, as it has white ray florets touched outside with 

 crimson. 



Gnaurs or Embryo buds on Tulip-tree. — Mr. F. W. Burbidge, 

 V.M.H., sent specimens with the following note : " At Sybil Hill, Clon- 

 tarf, belonging to the demesne of St. Anne's, there is growing a Tulip- 

 tree (Liriodendrou tulipiferum), and on the lower part of the gnarled old 

 trunk large rounded warts or ' gnaurs ' are clustered. They vary in size 

 from 2 to 3^ inches across, and look like rough -skinned Potatos. Simi- 

 lar warts on Beech, Cedar, Deodar, and other trees are not uncommon, 

 but I never happen to have seen a Tulip-tree produce them before. They 

 consist of thick, soft, fleshy 'bark,' surrounding a hard woody core. 

 Their branch-like character is shown by a twig and leaf growing from
