cxlii PROCEEDINGS OF THE EOYAL HORTICULTURAL SOCIETY. 



There is no necessity for following up the history of this Fumago 

 varians except to remark that its full development is attained in species 

 of Capnodium, which possess perithecia enclosing sporidia contained 

 in asci. 



Hybrid Tomatos. — Mr. Worsley showed somf very fine specimens of 

 Tomatos, the result of crossing the Grape- Tomato with a red garden 

 form. The hybrid was remarkable for the number of fruits borne by it, 

 some twenty-five being on one branch ; on another were two closely 

 arranged rows of fruit. Another hybrid was between an egg-shaped 

 Tomato and the Grape- Tomato as male parent ; the fruits were not large, 

 but remarkably well- shaped. 



Troposolum Hybrid. — Mr. Worsley showed flowers of T. Lobbianum 

 X majns, which were intermediate in character between the parents. 



Afjapantlius nmbellatus. — Mr. Worsley also showed a flower of this 

 plant with ten leaves to the perianth, from symmetrical increase. 



Watsonia Ardernci. — Dr. Masters showed leaves of this plant, which 

 are remarkable for being quite incapable of bearing the least fumigation 

 without injury. 



Beech-tree Bug. — Mr. Burbidge, V.M.H., Trinity College, Dublin, sent 

 samples of the w^ell-known pest, Cryptococcus fagi, exceedingly common 

 this year He wrote as follows: — "The specimen came from Croydon, 

 where trees 12 feet in circumference have perished. We have it in Dublin 

 on the stem of a Weeping Beech, in the College garden. This stem is of 

 the common Beech, and the weeping variety is grafted upon it, about 

 5 feet above ground. The pest only infests the bark of the stock up 

 as high as the graft-line, and does not spread or live on the scion or 

 weeping variety above the graft- line." Mr. Burbidge refers to an 

 opinion that this insect never attacks the purple Beech — an undoubted 

 error, as a large tree of it died at Ealing in 1898 from this cause, in 

 Professor Henslow's garden. 



Plane-tree Leaves Diseased: — Mr. Burbidge also sent leaves of this 

 tree attacked by Fumago. Several other plants, he observes, are similarly 

 attacked by it. 



Proliferous Barley. — Mr. Burbidge sent specimens of Barley with 

 extra short ears at the base, imitating the so-called " Egyptian Wheat." 

 They appeared among a crop of " Chevalier." He raised the question 

 w^hether it could have resulted from a cross with the six-rowed Barley ; 

 but without experiment this could not be decided. Probabilities would 

 seem, however, to be averse to this view, as no such crossing would apj)ly 

 to proliferous Wheat and other cereals, or to Plantains, in w^hich it is 

 of common occurrence. 



Prunus sp. Diseased. — Dr. M. C. Cooke reported upon specimens sent 

 to the last meeting by Mr. Veitch : " Plum and Cherry and some other 

 orchard trees suft'er from the attacks of what are, apparently, wound 

 parasites. These are in the form of a white mycelium, which grows 

 between the bark and the wood, and ultimately kills the tree. This is 

 presumed to be the mycelium of some Agaric, probably growing in the 

 vicinity of the tree, first attacking the root, and then proceeding upwards 

 beneath the bark. From the mycelium alone it is impossible to determine 

 the species, but in such cases it should be noted whether any Agarics
