Mimosece, in the " Transactions of the Linnasan Society," the 

 latter (a quarto volume in size) published as late as the jrear 

 1875. Both are perfect models of monograpkical work. 



An important series of monographs in another and more 

 condensed form was contributed to DeCandolle'a "Prodro- 

 mus," namely, the Tribe Ericeazm the seventh volume, the 

 Polemoniacece in the ninth, the Scrophulariacece in the tenth, 

 the Labiatce forming the greater part of the twelfth, and the 

 Eriogonece in the fourteenth ; these together filling LI 33 

 pages according to the surviving editor. If not quite the 

 largest collaborator of the De Candolles, as counted in pi 

 he was so in the number of plants described, and his work 

 was of the best. It was also ready in time, which is more 

 than can be said of the collaborators in general. 



There are few parts of the world upon the botany of which 

 Mr. Bentham has not touched — Tropical America, in the am-

 tivation of the narrow and more exhausted lid. I of British 

 botany. His "Handbook of the Briti>h Flora," for the nse of 

 beginners and amateurs, published in 1858, ha- gone through 

 four large editions. Its special object was to enable a h« --in- 

 ner or a mere amateur, with little or no previous scientific 

 knowdedge and without assistance, to work out understand- 

 ingly the characters by which the plants of a limited flora may 

 be distinguished from each other, these being expressed as 

 much as possible in ordinary language, or in such technical 

 terms as could be fully explained in the hook itself and easily
