172 THE JOURNAL OF BOTANY 



(1806-7), but by far his most important contribution is the 

 Tentamen Florce Bohemice. This work was prepared for pubU- 

 cation in the Ahliancllungen der konigl. bdJunischen Gesellschaft 

 der Wissenschaften ; it did not appear there, however, but was 

 issued subsequently in two volumes. The first of these, the 

 manuscript of which (with the exception of the preface and biblio- 

 graphy) was ready for printing in 1806 (Maiwald, Geschichte, 97 

 (1904) ), appeared in 1809, and was reissued in 1810. The second 

 volume, the manuscript of which was ready in 1811, appeared in 

 1814, and was reissued in 1815. A copy of the first issue is in 

 the botanical library of the British Museum (Natural History), 

 and is of special interest, as it contains an autograph presentation 

 note by Pohl dated " Prag, 19 Sept. 1809." Its title reads 

 " Tentamen Florae Bohemise. Versuch einer Flora Bohmens von 

 J. E. Pohl. . . . Erste [and Zweyte] Abtheilung. Fur die 

 Abhandlungen der konigl. bohmischen Gesellschaft der Wissen- 

 schaften. Prag. 1809 [and 1814] . Gedruckt bey GottHeb Haase." 

 It was reissued without alteration or addition by G. W. Enders 

 & Co., of Prag, in 1810 and 1815 ; it is to this reissue that Pritzel 

 refers in the Thesaurus (ed. 2. n. 7229), and copies of it are in the 

 libraries at Bloomsbury and Kew. Pohl seems to have based his 

 work on H. A. Schrader's unfinished Flora Germanica, 1806; part 

 of the cost of publication was defrayed by the Konigl. Bohmische 

 Gesellschaft der Wissenschaften. 



The work is as interesting to the botanist as to the biblio- 

 grapher. Many of the names which were here first published 

 have been omitted from the Index Keivensis, and it is obvious 

 from the mode of citation of those included that the compiler did 

 not consult the work itself, but quoted it at second-hand. This 

 fact seems to warrant the re-publication here of the names first 

 published in the Tentamen. These are given in the following list, 

 w4iich includes one British plant — " Gladium Mariscum mihi," 

 with full description, synonymy, &c., which antedates Eobert 

 Brown's pubhcation in Prodr, Fl. Nov. Holland, p. 236 (1810). It 

 has not been thought necessary to give a list of the species cited 

 in the genera Gallion, Lysimachusa, and Gentianusa, as these 

 differ only in their terminations from names already in use under 

 Galium, Lysimachia, and Gentiana respectively. The first column 

 contains Pohl's new names with a reference to the Tentamen, and 

 in the second are their citations as given in the Index Keivensis, 

 with their synonyms : —
