Dr. Hooker on American Botany. 27 B 



South Shetland," (U. fasciata of Torrey) ; by Mr. Lewis de 

 Schweinitz, in a valuable "Monograph of the genus Viola ;''^ 

 by Mr. Nuttall, on a " collection of plants made in East Flo- 

 rida by Mr. Ware ;" by Mr. M. C. Leavenworth, on " four 

 new species of plants from Alabama 5" by Professor C 

 Dewey of William's College, upon " Carices.^^ 



In the Journal of the Academy of Sciences, the Botanical 

 Memoirs are entirely from the pen of Mr. Nuttall. 



The Annals of the Lyceum of Natural History of New- 

 York were only commenced last year; but the numbers, (of 

 which we have received five from that excellent institution,) 

 contain several communications on the subject of botany. In 

 No. I. is a " Synopsis of the Lichens of the state of New- 

 York," by Mr. A. Halsey ; and a description by Dr. Torrey 

 of " some new and rare plants collected in the rocky moun- 

 tains, during the expedition thither, commanded by Major 

 Long, by Dr. Edwin J.ames ;" in No. II. a "Synopsis of the 

 Carices,^^ by Dr. Schweinitz. No 111. contains an article "on 

 the American Ulriculariie,*'' by M. Le Conte, who enumerates 

 1 1 species. No. IV. " on the genus Gratiola,^^ by the same 

 author. No. V. " on the genus Ritellia," by M. Le Conte ; 

 and on " some new grasses found by Dr. James, on the 

 i'ocky mountains," by Dr. Torrey. 



Mr. Schweinitz, whom we have already more than once 

 alluded to, is a native of Germany, where, as well as through- 

 out Europe, he is advantageously known, in conjunction with 

 M. Albertiui, as the author of a Latin work on the Fungi of 

 Upper Lusatia. Since his residence in America, he has con- 

 tinued to dedicate most of his attention to the fungi ; and his 

 manuscript, containing an account of 1373 fungi found in 

 Upper Carolina alone, was edited by Dr. Schwaegrichen in 

 1823, under the title of " Synopsis Fungorum Carolina Su- 

 perioris" in a thin volume, 4to ; and it is not a little singular 

 to observe how many of these are common to Europe as well 

 as America. 



We shall close our notice of American botanical publica- 

 tions by the mention of that, which, if we may judge from the 

 first number, (which is all that we have yet received from the 



rnunicated the plant, to Dr. Torrey, seems inclined to believe this lichen 

 lo be the only vegetable production of New South Shetland. We have 

 received half a-dozen different ones, and will venture to predict that- 

 many more will yet be di^covered^
