Graft Hybrid, Peach and Almond. By L. Daniel and I. 



Delpon (Rev. Hort. pp. 394-395. Sept. 1, 1913). — An interesting 

 record of a case somewhat similar to that of Cytisus Adami. A Peach 

 grafted on an Almond yielded as first crop true Peaches, but in the next 

 year a number of buds were produced of mixed character, Almond, 

 Peach, and intermediates being intermingled. Two seeds of the graft 

 have yielded trees, one strong, the other feeble, which have not so 

 far flowered, but the foliage presents resemblances to both kinds. 

 These results assimilate to those produced by Amygdalus communis 

 persicolor, a presumed sexual hybrid. — C. T. D. 



Grafts, On the Transmission through the Graft of Chemical 

 Substances formed by the Stock Plants and vice versa. By 



Lucien Daniel (Rev. Hort. pp. 329-330, July 16, 1913 ; pp. 348-350, 

 August 1, 1913 ; 2 ill.). — A very interesting article, dealing with the 

 effect of th« stock on the scion in connexion with fruit production, 

 &c. A proved instance that such transmission of different chemical 

 products does occur as cited when a graft of a tomato on a Belladonna 

 stock produced tomatos containing an alkaloid allied to atropine, 

 and capable of producing the same pathological effects, though nor- 

 mally there is no trace of this in the tomato on its own roots. — C. T. D. 



Grape « Panariti ' (U.S.A. Dep. Agr. Year Book, 1911, p. 433; 

 col. plate). — A Grecian variety used for drying for the Currant of 

 commerce. Recommended for experiment in California. — E. A. Bd. 



Grasses, New, for Southern Climates (U.S.A. Dep. Agr. Year 

 Book, 1912, pp. 495-504 ; 6 plates). — An account of experimental 

 trials with New Grasses for fodder purposes. Rhodes Grass, Sudan 

 and Tunis Grass, and others are described and figured, and cultural 

 methods indicated. — E. A. Bd. 



Grass Parasite, A New. By G. Massee (Jour. Bd. Agr., vol. xx. 

 No. 8, pp. 701-703 ; 1 plate). — The disease caused by the fungus 

 Cladochytrium graminis, Biisgen, which was first observed in this 

 country in 1908, has been notified at Kew during 1913 from several 

 widely separated localities in the south of England. The disease, 

 which so far seems to be most prevalent on lawns, tennis grounds &c, 

 first appears in the form of small yellowish patches, a few inches across, 

 scattered over the lawn. These patches increase in size, more par- 

 ticularly after a fall of rain, and often encroach on each other, forming 

 large irregularly shaped areas, which eventually become brown, owing 

 to the entire disappearance of the grass. 



Watering after rain has fallen with a solution of iron sulphate, 

 half a pound to a gallon of water, is recommended. The treatment 

 should be repeated two or three times at intervals of about ten days. 



The fungus is probably distributed with grass seed, for microscopic 

 examination showed that 5 per cent, of the seeds in a sample which 

 had produced a diseased crop contained resting-spores of the fungus 

 in the seed coat. It is doubtful whether any known method of seed
