vated intentionally (voloutairement), and (2) those that are cnltivated 

 in opposition to the wishes of man, those plants, namely, which intrude 



themselves amongst those cultivated by man, and which are found no- 

 where else. The latter subject is dismissed in a very few sentences, 

 the plants alluded to having been previously enumerated under the 



-I 



head of naturalized species. The subject is however, we think, capable 

 of much fuller elucidation than it has yet received, and is a very curious 

 and interesting one. 



Under the head of History and Origin of Cultivated Plants, M. de 



CandoUe arranges the latter according to the organs for which they 

 cultivated, as for their roots, bulbs and tubers, stems, leaves, flowers 

 or bracts, fruits, and seeds ; to this list might have been added those 

 cultivated in tropical countries especially, for the beauty or odour of 

 their flowers, as various Hihisci, the Nyctanthes Arbor -tristis^ and Horse 

 Chestnut, of which the origin is supposed to be unknown, but of which 

 some, at any rate, may be traced to known wild species, of wWch they 

 appear to be varieties induced by cultivation. 



Following the discussions on the origin of the cultivated species, are 

 tabulated results, in which the species treated of are arranged according 

 to the following classes : 



1. Those found absolutely wild, and about whose specific identity 



there need be no question. (85 species.)
