DE CANDOLLE'S PRODROMUS. 31 



635 species, Peperomia of 389 !) ; Chloranthacece by Solms- 

 Laubach of Halle, reduced to three genera ; and finally, Gar- 

 ryacecB by the editor, comprising nine species of Garrya. It 

 appears that the latter end of the volume was printed first, 

 which explains the omission of G. huxifolia, a species discov- 

 ered in northern California by Bolander, and published a 

 year and a half ago. If one or two collaborators wiU now 

 bring up their arrears, the editor may very soon have the 

 great satisfaction of announcing the completion of the great 

 Dicotyledonous series. 



The seventeenth volume of De CandoUe's " Prodromus " 

 contains, in the first place, certain small outlying orders, or 

 some of them genera that have to do duty as orders, which 

 on various accounts have been left out of the " Prodromus " 

 as it went on, namely, Sarraceniacece^ Phytocrenece, Car- 

 dioptemdecBj Salvadoracece, Cynocrambe, Batidacem (one Ba- 

 tis), Lennoacece (by Solms-Laubach), Podostemacece (by 

 Weddell). Then iVepew<A«cece, by Dr. Hooker ; Cytinacece^ 

 by the same ; BalanophoraceoB^ by Eichler ; Vlmaceoe^ by 

 Planchon ; Moracem^ by Bureau ; and a synopsis of the genera 

 of ArtocarpecB. For the complete elaboration of the last 

 family the volume has been a good while kept back, and has 

 at length been issued, and (sad to say) the work concluded 

 without it. It is to be hoped that whenever M. Bureau 

 finishes his undertaking, the publishers of the " Prodromus " 

 may print the Artocarpem uniformly with the rest, so that it 

 may be appended. 



Then follow a few pages of Genera omissa, with brief 

 references, indicating that they are, or may be, so far as has 

 been made out or conjectured ; and finally, the wearied editor 

 appends his " Prodromi Historia, Numeri, Conclusio." It is 

 a terse and highly interesting account of this work, which 

 (including the two preceding volumes of " Systema") occupied 

 his celebrated and indefatigable father from the year 1816, or 

 earlier, down to the end of his life, in 1841, and himself to 

 the close of the past year ; an enumeration of the contributors 

 who have worked up particular families or genera ; an enu- 

 meration of the orders, specifying the volume which contains
