and also from pieces of the stock. It is necessary 

 however with this, as with the olive, to cut up the 

 wood into pieces not less than a span long and not to 

 strip off the bark. 



Trees then grow and come into being in the above- 

 mentioned ways ; for as to methods of grafting ^ and 

 inoculation, these are, as it were, combinations of 

 different kinds of trees ; or at all events these are 

 methods of growth of a quite different class and 

 must be treated of at a later stage. 



II. Of under-shrubs and herbaceous plants the 

 greater part grow from seed or a root, and some in 

 both ways ; some of them also grow from cuttings, 

 as has been said,"^ while roses and lilies grow from 

 pieces of the stems, as also does dog's-tooth grass. 

 Lilies and roses also grow when the whole stem is 

 set. Most peculiar is the method of growth from an 

 exudation ^ ; for it appears that the lily grows in 

 this way too, when the exudation that has been 

 produced has dried up. They say the same of* 

 alexanders, for this too produces an exudation. 

 There is a certain ^ reed also which grows if one cuts 

 it in lengths from joint to joint and sets them ^ 

 sideways, burying it in dung and soil. Again they 

 say that plants whicli have a bulbous root are 

 peculiar in their way of growing ' from the root. 



The capacity for growth being shewn in so many 

 ways, most trees, as was said before,^ originate in 

 several ways; but some come^ only from seed, as silver-
