1. Carnot1 Linnaz1 Systema, Genera, Species Plantarum uno volu- 
mine. Editio critica, adstricta, conferta; sive Codex Botanicus Lin- 
neanus, tectum Linneanum integrum ex omnibus Systematis, Generum, 
Specierum Plantarum editionibus, Mantissis, Addimentis, selectumque 
ex ceteris ejus botanicis libris digestum, collatum, contractum, cum plena 
editionum discrepantia exhibens : In usum Botanicorum practicum edi- 
dit brevique adnotione explicavit Hermannus Exernarpus Ricurter, 
M. Dr. Prof. Dresd., ete. Leipsic, (Wigand,) 1840.—This book is, as 
its title denotes, a complete digest of the writings of the immortal Lin- 
nus upon systematic botany, an undertaking of great labor, and, we 
believe, very faithfully executed. It forms a volume of 1100 pages of 
the small folio or imperial octavo size, (the same as that of the new 
edition of Steudel’s Nomenclator,) closely printed in double columns ; 
prefaced by some critical and explanatory editorial observations, and 
by a complete list of the botanical writings of Linnzus, with notices of 
the different editions, a catalogue of the authors cited by Linneus, &e. 
The prefaces, dedications, and introductory observations of all the sys- 
tematic works are next given ; and the body of the work is devoted to 
the genera and species, in which, by a well arranged system of abbre- 
viations, nearly the whole Linnzean text, and the changes or variations 
of the different editions, are brought within a moderate compass. Such 
a thesaurus is of great value to botanists, and especially to those av 
do not possess the original editions of all ihe works it comprises, m 
of which are exceedingly rare. To the volume is appentled a euikis 
index to the Linneean genera and species, with all the original synonymy, 
entitled : In Codicem Botanicum Linneanum Index Alphabeticus, Gen- 
erum, Specierum ac Synonymorum omnium completissimus, composuit 
atque edidit Dr. G. L. PetErmann, which is paged separately, and oc- 
cupies 200 pages, printed in triple columns, extending the work to above 
1300 pages. It is published at 16 Saxon thalers. 
2. Genera, Species, et Synonyma Candolleana, alphabetico ordine 
_ disposita, seu Index generalis et specialis ad A. P. De Candolle Pro- 
dromum Syst. Nat. Regni Vegetabilis: auctore H. W. Buex, M. D. 
(Berlin.)—An index of the genera and species contained in the Pro- 
dromus of the lamented De Candolle, and of their synonyms, has been 
greatly needed, those of the several volumes of that most important 
work extending only to the genera. This want Dr. Buek has in part 
Supplied by publishing an index to the fifth, sixth, and first part of the 
seventh volumes of the Prodromus, that is, of the immense family of
