clxxii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Baspberry, Wineberry, Blackberry Hybrids. — Mr. H. Peerman sent 

 specimens of the foliage (the fruits had fallen off, and could not be 

 identified) of three hybrids, Blackberry x Raspberry, Raspberry x Wine- 

 berry, Wineberry x Raspberry. They were considered most interesting, 

 and he was requested to send them again next year, each in a separate 

 box, with both fruit and foliage. 



Bud Formation. — Mr. J. Robson sent "a section from a young 

 Sycamore exhibiting the extraordinary facility with which this tree 

 develops woodbuds from the bark." The tree had been budded on the bare 

 space between two leaves, and the bud had failed, but from the base of 

 the incision the stock had sent out a growth " where no eye previously 

 existed. I have twenty-five or more examples of the same thing in 

 Sycamores, but though I have budded many subjects I have never noticed 

 it in any other genus." 



Hippeastrum Blistered. — Dr. Bonavia sent some leaves of Hippe- 

 astrum " covered with something that looks like scale, but which adheres 

 so closely to the epidermis that it is difficult to remove." The scalelike 

 blotches, on examination, proved to be not of insect formation at all, but 

 blisters due probably to defective root-action, itself due to a check of some 

 sort, such as cold or too much wet. 



Cryptococcus on Weymouth Pine. — Mr. R. Knight-Bruce sent a 

 specimen of bark literally swarming with the white woolly or waxy 

 Cryptococcus which attacks Pines, and which, he says, is rapidly spreading, 

 and killing plantations of the Weymouth Pine. The Committee considered 

 the case almost hopeless, but suggested spraying the trees with a 

 paraffin emulsion. Rev. W. Wilks said he had but little hope in spraying 

 Cryptococcus, as, unless the sprayer was peculiarly strong and powerful, 

 the liquid would not penetrate the downy wax with which the insect 

 covers itself. He had known a case of a Beech-tree being saved by hand 

 scrubbing with a brush, using soft soap and paraffin emulsion, but he had 

 never known spraying to be successful. 



Discoloured Vine-leaves. — These were received from Mr. Neild, of 

 Holmes Chapel. Dr. Cooke reports : " Vine-leaves with broad irregular 

 patches of bright coloration have been known and observed for the past 

 half-century. Sometimes the colour is yellow or becoming brown, and 

 sometimes reddish or claret colour. In America it is known as the 

 Californian Vine disease (see U.S.A. Dep. Agr., Div. Veg. Pathol. Bull. n. 2, 

 1892). This or a similar disease is known in Sicily as 'Folletage,' and in 

 Italy as £ Mal nero.' No satisfactory reason has yet been assigned 

 for this affection, as no trace of fungus has been found, and there is no 

 cause to suspect that fungi of any kind have anything to do with the dis- 

 coloration. Leaves are constantly being submitted to the Scientific 

 Committee for report as to the cause or remedy, but none can be given." 



Floriferous Sweet Pea. — Mr. Hunt sent a flower-stalk of Sweet Pea 

 having seven fine blossoms. 



Proliferous TIelenium. — The Rev. C. Wolley-Dod, V.M.H., sent flower- 

 heads of this, remarking that one particular plant in his garden always 

 produces them ; and that, as a rule, small secondary flowers grow out of 

 the disc. 



Campanula lactiflora, linear-leaved. — The Rev. C. Wolley-Dod sent a
