as to species, but are usually few as to individuals." In discussing pre- 

 ventive measures, various methods of cultivation are mentioned which are 

 of benefit in this respect. Arsenical sprays are recommended as the best 

 remedial agents, and of these the one that takes the first place is arsenite 

 of lime with soda. This compound in the States is about a quarter of the 

 price of "Paris green." It is made by boiling one pound of white arsenic 

 and four pounds of sal soda (crystal) in one gallon of water until they are 

 dissolved ; the loss of water by evaporation should then be made good. A 

 pint of this solution should be added to fifty gallons of water, and finally 

 three or four pounds of freshly slaked lime should be added. " It is always 

 desirable to have an excess of lime present, in order to prevent all danger 

 of burning." It is recommended that the spray should be applied a few 

 days after the blossoms have fallen, and before the calyx has closed, and 

 another about two weeks later, when the majority of the larvae are 

 entering the fruit. Spraying for the second generation should be carried 

 out as soon as the caterpillars are hatched. This bulletin is well illustrated 

 with sixteen plates and various figures in the text, and concludes with a 

 very full bibliography down to 1898. — G. S. S. 



Coelogyninse, Anatomy Of the. By H. Zornig {Engl. Bot. Jahrb. 

 xxxiii. March 1904, pp. 618-741 ; 60 figs.). — The author has investigated 

 the leaf-anatomy, and in part also the anatomy of the tubers of fifty-four 

 species of this tribe of Orchids, including the genera Gcelogyne, Pleione, 

 Pholidota, Neogy?ie, Platyclinis, Otochilus, Crinonia, and Dendrochilurn. 

 His figures illustrate the form of the stomata and surrounding epidermal 

 cells, the general arrangement of the tissues in a transverse section of the leaf, 

 and also to a smaller extent histological details of the transverse section 

 and the nature of the cell-contents. He gives a key by means of which 

 species of Pholidota, Platyclinis, and Ccelogyne may be determined by a 

 study of the leaf-anatomy, and to a more limited extent of the structure 

 of the pseudobulb. — A. B. B. 



Coffee-leaf Stilbum. Sur la Maladie du Cafeier, Stilbella flavida. 

 Par M. A. Puttemans (Bull. Soc. Myc. France, xx. fasc. 3, 1903 ; 1 plate). — 

 This communication rehearses that this fungus on the leaves, fruit, and 

 young branches was first described by Cooke as a Hyphomycete under 

 the name of Stilbum flavidum in 1880 ; disputed by von Tavel in 1894, 

 who contended that it was a Hymenomycete, and called it Physalacria ; in 

 1896 Spegazzini also considered it a Hymenomycete, and called it Pistillaria ; 

 afterwards, in 1903, Kohl restored it to its position as a Hyphomycete, 

 and called it Stilbella flavida, after Lindau. The paper is principally 

 descriptive and technical, and treats also of the relationship of the Stilbum 

 to Phyllosticta coffeicola, with which it was often associated. — M. C. C. 



Coffee Parasites. Champignons parasits sur les Cafeiers. Par Dr. 

 Geo. Delacroix (Bull. Soc. Myc. France xx. fasc. 3, 1904 ; 1 plate). — The 

 species enumerated in this paper, which is mainly descriptive, are 

 Gapnodium coffece (Pat.) on the leaves ; Anthostomella coffece (Del.) on 

 floriferous branches, Mexico ; Hendersonia coffece (Del.) on branches, 

 Mexico ; Bhabdospora coffeicola (Del.) on dead branches, Mexico ;
