ENQUIRY INTO PLANTS, III. in. 1-3 



when it grows in the mountains, is called zygia, 

 when in the plain, gleinos : others, however, 1 classify 

 differently and make maple and zygia distinct trees. 



2 All those trees which are common to both hill 

 and plain are taller and finer in appearance when 

 they grow in the plain ; but the mountain forms are 

 better as to producing serviceable timber and fruits, 

 with the exception of wild pear pear and apple ; 

 these are in the plain better in fruit and also in 

 timber ; for in the hills they grow small with many 

 knots and much spinous wood. But even on the 

 mountains all trees grow fairer and are more vigorous 

 when they have secured a suitable position ; and, to 

 speak generally, those which grow on the level parts 

 of the mountains are specially fair and vigorous ; 

 next to these come those which grow on the lower 

 parts and in the hollows ; while those that grow on 

 the heights are of the poorest quality, except any 

 that are naturally cold-loving. But even these shew 

 some variation 3 in different positions, of which we 

 must speak later ; for the present we must in our 

 distinctions in each case take account only of the 

 differences already mentioned. 



Now among wild trees those are evergreen which 

 were mentioned before, 4 silver-fir fir ( wild pine ' box 

 andrachne yew Phoenician cedar terebinth alaternus 

 hybrid arbutus bay pkellodrys 5 (holm-oak) holly 

 cotoneaster kermes-oak tamarisk ; but all the others 

 shed their leaves, unless it be that in certain places 

 they keep them exceptionally, as was said 6 of the 

 plane and oak in Crete and in any other place which 

 is altogether favourable to luxuriant growth.
