362 Analysis of Scientific Books and Memoirs. 



some time in the Mauritius, New Holland, at the Cape, in Trinidad, &c; 

 and on his return has published beautiful specimens, under the titles of 

 Floral of the separate countries. Helsinborg and Bojer have directed 

 their attention principally to the plants of the Mauritius, Madagascar, 

 and the opposite eastern coast of Africa, in which latter country Helsin- 

 borg has fallen a sacrifice to the unhealthiness of the climate. Bojer still 

 remains at the Mauritius. 



We must now devote a brief space to the work immediately under 

 our review, Meriens and Koch's Flora of Germany, or, as the title express- 

 es it, " T. C. liohling's Deutschland's Flora neu Bearbeitet von Mertens 

 und Koch." Much as the botany of Germany had been explored, and nu- 

 merous as were the partial Floras of the country, it was to be regretted 

 that there did not exist one work including a full and complete account 

 of all the plants of Germany, similar to our Flora Britannica and English 

 Flora. Roth's " Tentamen" was manifestly very imperfect. Hoffman's 

 " Flora Germanica" is little more than a synopsis. " Schrader's Flora 

 Germanica" promised to make up every deficiency, but, (from what cause 

 we know not,) the first volume, extending to the end of the third class, has, 

 in the space of twenty years, been succeeded by no other. It was left for 

 the authors now immediately under consideration, to commence such an 

 undertaking ; and it is not a little remarkable, that the two first volumes 

 made their appearance in Germany nearly at the same time with those of 

 the " English Flora" of our Smith ; a work with which, perhaps, it may 

 best be compared for general plan and arrangement. It is entirely in the 

 German language. The first volume is devoted to some introductory mat- 

 ter, an Alphabetical Dictionary of Terms, and a general view of the Artifi- 

 cial and Natural Arrangement. 



The second volume, all we believe that has yet been published, com- 

 mences with the description of the genera and species, classed according 

 to the Linnsean system, comprising the first four classes, and is concluded 

 by a very copious index both of species and synonyms. Each class is 

 headed by an enumeration of the genera, with their full characters, and, 

 as in Smith, the name of the natural order to which they belong ; so 

 that, by referring to the character of that order in the first volume, the 

 student will become well acquainted with their arrangement in both sys- 

 tems. It will be most to our purpose, in the few observations we shall 

 here offer, to confine ourselves to the second volume of the work, and to 

 the mention of such plants as, from their identity with those of our own 

 island, may be likely to be most interesting to the British botanist. 



Of such, the first class contains Hippuris and Zostera ; Chara as well as 

 Callitriche being removed to the Diclinia. In Diandria we have Salicor- 

 nia and Lemna. With the Salicornia herbacea the authors unite, as we 

 have done in the Flora Scotica, the S. procumbent of Smith. The spicate Ve- 

 ronicas are, with propriety, much reduced in point of number of supposed 

 species. Circcea Lutetiana and alpina are kept distinct, and the C- inter- 

 media mentioned as a variety, but of which species the authors seem 

 doubtful. Sprengel is perhaps correct in considering them all the same-
