POPULAR SCIEXCE REVIEW. 
some day^ at no very distant period^ we shall know in a spon- 
taneous state the immense majority^ jierhaps the totality of om* 
cultivated species. 
M. Alphonse de Candolle gives a list of 157 plants^ which he 
selects because most commonly cultivated by inan_, and of 
these 85 have been found wild — that is to say, identical with 
the cultivated plant, or at least with some of its varieties. If 
to these species are added those which are most probably 
wild, or about which hardly a doubt remains, we may consider 
117 as having been identified in a spontaneous state. In short, 
the species which we historically know to have been first culti- 
vated in Europe, have been found wild in Europe ; and those cul- 
tivated species of which the wild form has not yet been found, 
are all foreign plants cultivated abroad, and in countries which 
have not yet been explored. 
The following is the list of cultivated ^fiants, given by De 
Candolle, of which the wild forms have been found, 85 in 
number, and here inserted as likely to be interesting to our 
readers : —
