Da/lieu, which brings that valuable work down to plate 1920. About the 

 same time he published " Nomcnclatura Floras Danica; cvu-ndata cum in- 

 dice Systematica et Alphabet ico" in 8vo,pp. xxviii. 214, containing indexes 

 of the plants; 1. according to their order of publication; 2. accoiding to 

 the Linnaean system ; 3. alphabetical. 



The preface contains an interesting account of the origin and progress of 

 that work, (published principally at the expence of the King,) which was 

 commenced by George Christian Oeder of Anspach, who, in 1752, was ap- 

 pointed Professor of Botany in Copenhagen; and in 1761, published a 

 prospectus and specimen of the Flora Danica, which, between that time 

 and 1771, (when he received an appointment in Norway, which took him 

 from this work,) was followed by ten fasciculi, containing 600 plates. 

 Those in the early parts are drawn and engraved by the Roeslers, father 

 and son, and are much superior to those in the later parts, where he em- 

 ployed inferior artists. Oeder was succeeded in 1772 by the celebrated zoo- 

 logist, Otto Frederick Muller, who published Fasciculi xi.-xv. plates 601- 

 900. 



He attended more particularly to the lower orders of plants, Conferva? 

 and Fungi, hitherto much neglected ; though it appears he had scarcely 

 determined in what part of the system of nature Fungi should be includ- 

 ed, as he about the same time published Clavaria militaris in his Zoolo- 

 gia Danica as an animal, and in the Flora as a plant. The plates were 

 during Muller 's editorship executed by a brother of his, and are much in- 

 ferior to those of the Roeslers. 



To him succeeded in 1783 a worthy pupil of Linnaeus, (under whom he 

 studied for several years at Upsal) Martin Vahl, by whom the work was 

 much improved, both in accuracy and in execution, though the mosses 

 are frequently so imperfectly represented in their most essential characters, 

 that it is difficult to refer them to their species or even genus. He pub- 

 lished Fasciculi xvi.-xxi. plates 901-1260. 



The present editor, Jens Wilken Hornemann, succeeded in 1805, and 

 had last year continued the work to Fasciculus xxxii. plate 1920; and is 

 zealously proceeding in his labours to which the botanical world is so 

 much indebted. He calculates, that, reckoning the Cotyledonous plants 

 of Denmark at 1600, and the Acotyledonous at 3200, about f of the former 

 or 1200, and little more than \ of the latter or 900, are published.
