Ranunculacece, and ending with Lycopodiacem ; and the arrange- 

 ment of the orders^ genera, and species appears to be, with only 

 slight exceptions, the same as that of Cosson and Germain's ex- 

 cellent work on ' The Flora of the Environs of Paris/ The 

 ample descriptions of the orders are followed by dichotomous 

 analytical tables of the genera, and the description of the genera 

 is followed by similar synopses of the species. The species are 

 named, numbered, and localized. The ordinal description is fol- 

 lowed generally by a popular and brief notice of the economical 

 and medicinal uses and preparations obtainable from the plants 

 of the Order. 



Our author is not quite so liberal in his estimate of species as 

 some Continental botanists, Jourdan, Boreau, and even some 

 British members of the brotherhood. He enters only seven 

 aquatic Ranunculi, not under the name Batrachian, but simply as 

 constituting part of the genus Ranunculus. These are R. liede- 

 raceus, R. tripartitus, R. ololeucus, R. aquatilis, R. trichophyllus, 

 R. divaricatus, and R. fluitans. 



Cerastium tetrandrum does not' appear in this Belgian Flora, 

 and C. semidecandrum is entered with the remark, " Espece peu 

 connue,'' obscure species. Elatine Hydropiper is qualified by espece 

 tres-douteuse. 



Acer Pseudo-Platanus is not distinguished by the sign of 

 alienism. Corydalis lutea is branded, but not C. solida. 



The genus Rubus, the puzzle and plague of German and Eng- 

 lish botanists, is represented in Belgium by only four species, 

 viz. R. saxatilis, R. idaus, R. ceesius, and R. fruticosus. for- 

 tunati Belgici ! exclaim the tyros, sua si bona norint. We hope 

 they are sufficiently thankful, and that other botanists are en- 

 dowed with patience, for which virtue they will have much occa- 

 sion in England, Germany, and Sweden, where Nature appears 

 to enjoy the malicious pleasure of mystifying her most ardent 

 and devoted admirers with never-ending, still-beginning, new 

 , forms of Brambles, Buttercups, Hawkweeds, and Willows. 



The list of Hieracia is of moderate dimensions, only exceed- 

 ing that of the Rubi by three species, one of which, H. Auricula, 

 is one of the most doubtful of British Hawkweeds. Even here, 

 in Belgium, a new form or species has been discovered and dis- 

 tributed by M. Crepin, who promises to publish the result of 

 his labours in this fruitful field of botanical investigation.
