A LEDEBOUR, vol. 2, part 1 ; Stuttgard, 1844. 
We are glad to be able to announce the appearance of the 
first part of the second volume of this laborious under- 
taking, of which we gave a brief notice at p. 126 of our last 
Volume of this Journal. This second volume commences 
with the Amygdalee ; and the first part closes with Dipsacee. 
All the specific characters, and synonyms, and descriptions, 
are done with great care. Each volume commences with a 
* Conspectus Generum et Specierum," and at the close of 
each order are tables divided into three heads: 1. * Ranuncu- 
lacearum (or whatever the order may be) distributio in Im- 
perio Rossico.” 2, “ Ranunculacearum Flore Rossice dis- 
tributio quoad durationem.” 3. “Tabula comparativa Ranun- 
culacearum Floræ Rossice et Germanice ;" and 4, “ Tabula 
comparativa specierum e Ranunculacearum ordine, que 
singulis Flore Rossice regionibus cum aliis et cum Germania 
communes sunt."
