"Again there are the things of which such parts (root, stem, leaf) 

 are composed, namely, bark, wood, and core (in the case of those plants 

 which have it), and these are all 'composed of like parts.' Further, 

 there are the things which are even prior to these, from which they are 

 derived — sap, fibre, veins, flesh ; for these are elementary substances — 

 unless one should prefer to call them the active principles of the ele- 

 ments ; and they are common to all parts of the plant. Thus, the 

 essence and entire material of plants consists in these."
