INDEX GENERUM PHANEROGAMARUM. 317 



have been rearranged for this Index by Prof. Eadlkofer) where the 

 numbers stand as 24 against 38 ; and in Asciepiadea, where they 

 are 146 against 204. M. Durand has of course simply taken these 

 genera on the faith of their authors, and it is more than probable 

 that many of them would not be accepted by Bentham and Hooker 

 as coming up to their standard of distinctness; but critical revision 

 is no part of M. Durand's work, and he has wisely confined himself 

 to the lines he has laid down. 



The plan of the book will be best shown by an extract, which 

 we take from the first page : —

M G." stands, of course, for Bentham and Hooker's 'Genera'; 

 the other abbreviations need no explanation. There are two 

 series of numbers : one running throughout the book, a useful 

 return to the plan adopted by Endlicher ; the other peculiar to each 

 order. Every care has been taken to insert additions in the place 

 foey hold in relation to their allies, and this, again, is useful to 

 those whose libraries are limited : it is, indeed, to this care in 

 small details that much of the excellence of this Index is due. 

 The place and year of publication of new genera is, of course, in- 

 dicated; thus:

Sp. 1. Madagascar. 



As might be expected, a certain number of names are here 

 proposed for the first time, owing for the most part to the double 

 occupation of certain generic titles. These occur in their proper 

 places, but a list of them is thoughtfully placed by M. Durand at 

 the beginning of the book. It may be useful to cite them :—
