ENQUIRY INTO PLANTS, I. xiv. 3-5 



of plants too there is a class which cannot grow 

 except 1 in moisture, while others will indeed grow 

 on dry land, but they lose their character and are 

 inferior. Again of all trees, one might almost say, 

 and of all plants there are several forms to each kind ; 

 for hardly any kind contains but a single form. But 

 the plants which are called respectively cultivated 

 and wild shew this difference in the clearest and 

 most emphatic way, for instance the cultivated and 

 wild forms of fig olive and pear. In each of these 

 pairs there are differences in fruit and leaves, and in 

 their forms and parts generally. But most of the 

 wild kinds have no names and few know about them, 

 while most of the cultivated kinds have received 

 names 2 and they are more commonly observed ; I 

 mean such plants as vine fig pomegranate apple pear 

 bay myrtle and so forth ; for, as many people make 

 use of them, they are led also to study the differences. 



But there is this peculiarity as to the two classes 

 respectively ; in the wild kinds men find only or 

 chiefly the distinction of ' male ' and ' female,' while 

 in the cultivated sorts they recognise a number of 

 distinguishing features. In the former case it is 

 easy to mark and count up the different forms, in the 

 latter it is harder because the points of difference are 

 numerous. 



However we have said enough for study of the 

 differences between parts and between general 

 characters. We must now speak of the methods of 

 growth, for this subject comes naturally after what 

 has been said.
