number of hair-like teeth, there is a single very large lateral tooth 

 divided into numerous more or less slender hair-like pectinate lobes, 

 somewhat similar to the teeth of the Ovulidce. 



Prodromus Systematis Naturalis Reyni Vegetabilis ; Auctore 

 Alphonso de Candolle. Vol. 14. pars prior. Parisiis, 1856, 

 pp. 492. 



It is pleasing to have to announce the publication of another 

 volume of this invaluable work, and to be able to state that it fully 

 supports the character borne by its predecessors. These later volumes, 

 which treat of Monochlamydeous plants, are also the more acceptable 

 from their containing descriptions of Natural Orders, which, from 

 their position in the usual sequence of the orders, have not been ela- 

 borated in many extensive systematic works. Some authors have 

 commenced with the Ranunculacese, others have started from the 

 Algse or Graminese, and have not been enabled to extend their 

 respective works so far as to arrive at them. 



This volume contains the Polygonacess by Bentham and Meisner, 

 Myristicacese by A. de CandoUe, Proteacese by Meisner, Penaeaceae 

 and Geissolomaceae by A. de Candolie. The last of these, if really 

 a distinct order, is singular as including only one known species of 

 plant. The names of the authors are a sufficient surety that the 

 plants have been carefully studied and skilfully described and arranged. 

 We have had occasion to examine some parts of the book with 

 care, and must be allowed to express our admiration of them. We 

 may especially refer to the suborder Polygonese, including, with 

 others, the genera Rnmex and Polyyonum. Both of these present 

 exceeding difficulty from the large immber of closely allied species 

 included in them. They are genera to which Professor Meisner has 

 long paid much attention, and he seems to have drawn the line skil- 

 fully between the excessive tendency to combination of some writers, 

 and the extreme desire to found new species, of others. 



It is expected that other volumes will soon follow that which is 

 now before us ; and we may be allowed to express a hope, that the 

 early volumes of the * Prodromus' will soon be considered with a view 

 of their being re-written, in conformity with the more perfect state 

 in which their successors have issued from the press.
