Deterioration of certain species of orchids, G. Tkifkant and A. Hebert (Jour. 

 Soc. Xat. Hort. France, 19 (1897), p>p. 85-98). — A part of the data of the paper is given 

 in Rev. Hort., 69 (1897), No. 14. pp. 337, 338. Orchids taken from South America to 

 Europe do well for a year or two and then deteriorate so that new importations have 

 to be made. Chemical analyses made of plants when imported and at different times 

 several years later show an increase in percentage of mineral matter and a decrease 

 in percentage of nitrogen in the deteriorated plants. The authors believe this dete- 

 rioration due largely to improper nutrition under cultivation. Figures are given 

 comparing the amount of nitrogen in French rain water and in the rain water of the 

 native habitat of these orchids. The authors also think this deterioration due some- 

 what to the fact that under cultivation the flowers and flower stalks are always 

 removed from the plant, while in nature they remain, so that the nutrient matter 

 they contain may be reabsorbed by the plant. A table is given showing the amounts 

 of the various constituents in the flowers and flower stalks. A fertilizer is recom- 

 mended which is intended to supply proper nutriment, and in that way check 

 deterioration.
