 Salts of copper have been found efficacious in experiments 



made at Vineland, N. J., by A. W. Pearson. The treatment 



met with great success, as only ten to fifteen per cent., instead of 



ninety-five per cent., of the fruit was lost

The generic name antedates Mitremyces, Nees, under which 

 most of the species have been described. The American species 

 recognized are C. ci?iHabarinum,T)tsy,y^.nd C. Ravenelii (Berk.), 

 Mass. The development and structure of the former are well 



illustrated.

John Macoun. (8vo., 



pp. 248, Montreal, 1888.) 



This part is devoted to the Endogens, numbering seven hun- 

 dred and forty-seven species. The genera and orders are arranged 

 in accordance with Bentham & Hooker's Genera Plantarum- As 

 in the preceding parts, this is beautifully printed, the only serious 

 blunder in that line we have noticed being on page 9, where all 

 except the final letter of Goodyera have slipped in the presses, 

 and a curious result been attained. The system of nomenclature 

 adopted is that of Gray's Manual, except in Disponimy where 

 Mr. Macoun has followed the practice of some zoologists of citing 

 the author of the earliest specific name as author of the accepted 

 binomial, which is a good deal better than the plan current in 

 this country, but certainly open to the objection that it falsifies 

 the record. Mr. Macoun notes that Lnzula seems to be in great 

 confusion, and needs complete revision, in which we are disposed 

 to agree with him, although a bringing together of scattered ob- 

 servations is probably what is needed. Potamogeton Claytonty 

 Tuckerm., is antedated by P. Pennsylvanictis^ Cham., and P^ 

 ^ lone kites, Tuckerm,, by P, Jluitans L., as has already been 

 shown. I credited Cyperus flavescens to Canada on a specimen 

 from Niagara, from Herb. Leggett, marked " Niagara, Canadian
