Orchards, Sug-g-estions on Planting-. By O. E. White {U.S.A. 

 Exp. Stn., Mich., Bull. 262; July 1910). — One of the suggestions is 

 that it would be to tlie advantage of the orchardist if he furnished the | 

 nurseryman with scions or buds secured from trees of known productive- 

 ness, hardiness, and health (p. 10). — A . P. 



Oxalis adenophylla. By W. I. (Gard., July 29, 1911, p. 358).— 

 Has glaucous foliage similar to 0. enneaphylla from the Falkland 

 Islands, but the leaflets are more numerous and the rootstock is large 

 and bulbous, covered with a strong fibrous coat ; the flowers are borne 

 two and three on each peduncle and are of a rosy-pink with deeper | 

 lines and a purple base. It was collected near San Martin, in Chile, by 

 Mr. H. J. Elwes, growing at an elevation of 6,000 feet, and it first \ 

 flowered at Kew in May 1905. With a slight covering of bracken it 

 came through the winter all right and appears to be hardy. It is dwarf.

Paris Dahlias. By Hortulus (Le Jard., xxv., 573, p. 7; Jan. 5, 

 1911 ; coloured plate). — A useful note on the race of Striped Dahlias 

 introduced by MM. Millet et fils ; twenty-eight varieties are enumerated, 

 all distinguished as regards nomenclature by the name of the buildings 

 in Paris, e.g. Tour Eiffel, Trocadero, Pantheon, Metro, and Tuileries, 

 which are figured in the plate. — F. A. W. 



Peaches, Spraying- for Brown-rot. By C. A. McCue {Trans. 



Peninsular Hort. Soc, U.S.A., pp. 48-53; 1911). — A four-year-old 

 orchard of Champion peach was sprayed three times in the season of 

 1910 with various fungicides, and the best results followed the use 

 of self-boiled lime-sulphur spray, and a solution of commercial lime- 

 sulphur diluted 1 to 50. The latter, however, is not recommended, 

 as i't is always dangerous, and the foliage of the peach is extremely 

 fickle. The writer thinks that the ideal fungicide will be found when 

 some way is discovered of obtaining sulphur in an extremely finely 

 divided state, and atomic sulphur, which gave some good results in the 1 

 experiments, seems to be a good step in that direction. It is a 

 preparation of arsenate of lead and self-boiled lime-sulphur, that is 

 made with no more heat than that afforded by the slaking of the 

 lime. The use of lime-sulphur is further dealt with on pages 54 to 

 61 of the same publication. — A. P. 



Plum-rust, Life-History of. By E. F. Brooks, M.A. {New 

 Phytologist, x., p. 207; May 1911).— It is shown that the fungus 

 Aecidium punctatum, which attacks the anemone, especially Anemo7ie\T^ 

 coronaria, is a stage in the life-history of the plum-rust, Pucci?iia\ 

 pruni, in England, as it is in America, where it occurs on Hepatica\ fo 

 acutiloha, and in Russia. Destruction of affected plants of Anemone^ 

 coronaria would be of assistance in checking \he attack on the plum, i
