XXXViii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Eochelle and Saintes, which were both great places for this 

 import in olden times." 



Tomatos and Sulphate of Copper. — As another instance of 

 the possibly injurious effects of this substance, Dr. Masters 

 mentioned that M. Cornu found that its application, though 

 given in the prescribed quantity, proved fatal to the foliage of 

 the Tomato. Prof. E. Smith was asked if Tomatos and 

 Potatos suffered in California, as here, with the same fungus, 

 Phytophthora infestans. He replied that though Tomatos are 

 grown in 103 acre tracts there is no disease to which they are 

 subject, though Potatos are, if not to the same at least to an 

 allied form of fungus. 



Calochilus. — Mr. Ware sent a spray of this Australian Orchid. 

 It has an erect oscillating and fringed lip, the column being 

 declinate, and the whole flower a delicate mauve colour. Dr. 

 Kranzlin observed that it is very difficult to cultivate, as the 

 natural conditions of its native habitat cannot easily be supplied. 



Pinus sylvestris injured. — Dr. Masters showed a drawing of 

 a bough of this tree which he had observed at Boscombe. It 

 had apparently been split longitudinally into three pieces. They, 

 however, were reunited beyond the spaces injured. No cause 

 could be assigned for the remarkable occurrence. 



Dianthus attacked by Fungus. — Eev. W. Dod sent some 

 specimens of different species attacked with fungi. They were 

 sent to Kew for examination and report. 



Mcidium on Paris quadrifolia. — Mr. Plowright forwarded 

 specimens with the following communication: "During the 

 present summer Mr. W. Thompson, of Carlisle, and I have been 

 engaged in working out the life history of this iEcidium. The 

 details of our work we hope shortly to publish. In the mean- 

 time it seems desirable to state briefly that we find the iEcidium 

 on Paris quadrifolia, which occurs near Carlisle, is connected 

 with a Puccinia allied to P. sessilis, P. digraphidis, and P. 

 Phalaridis, which species, it will be remembered, have their 

 fecidiospores on Allium ursinum, Convallaria majalis, and Arum 

 maculatum respectively. The Carlisle Puccinia was found by 

 us to germinate freely from the end of April till the middle of 

 May. Applied to the above-named host plants it produced no 

 result, but succeeded upon Paris quadrifolia, on which plant it 

 gave rise to Spermagonia followed by zEcidia. The resulting
