Crinum Johnstoni. By Sir J. D. Hooker (Bot. Mag. tab. 7812).— 

 Nat. ord. Amaryllidece, tribe Amaryllece. Native of British Central 

 Africa. "It is clear," writes Sir Joseph, "that Tropical Africa is the 

 head-quarters of the genus, as it has yielded nearly forty species." It is 

 intermediate between C. latifolium and C. longifolium. It has flowered 

 freely in the succulent house at Kew. The flowers are umbellate, the 

 perianth is slightly tinged with pink, being 3 inches long, and the 

 green tube about 4 inches in length. — G. H. 



Currant Anthracnose, An Epidemic of. By F. C. Stewart and 

 H. J. Eustace (U.S.A. Exp. Stn. New York, Bull. 199 ; 1901).— During 

 the past season the Currant crop in the Hudson Valley has been seriously 

 injured by anthracnose, causing numerous small dark brown spots on the 

 leaves, which turn yellow and fall. Currant canes were quite generally 

 defoliated early in the season, and the exposure of the ripening fruit to 

 the sun brought about sun-scald and a loss of nearly one-half the crop 

 on some plantations. It is recommended that Currants be sprayed with 

 Bordeaux mixture regularly every season in the affected districts. — M. C. C. 



Cyclamen persieum, Old Corms of. By E. Hambro (Garden, 

 No. 1587 ; 19/4/1902). — A note of a system of culture that has been 

 followed with wonderful results. The corms, instead of being dried off 

 every year, were really never dried off at all, but grown on every year.

Cyclamen (persieum) splendens giganteum hybridum. By 



C. Stoldt (Die Gart. p. 366; 3/5, 1902; with coloured plate).— Herr 

 Stoldt, the first German specialist and hybridist, who has perhaps single- 

 handed done more than any other grower of Cyclamens to improve and 

 popularise these fine greenhouse plants. It is this gentleman who 

 claims the superiority of German Cyclamens over English. In a well- 

 written article he gives a history of the different forms raised by him.
