The Physiological Structure of Trees
March 16, 2010 § Leave a comment
Pliny (XVI:LXXII) says that there is a juice in the body of the tree which must be looked upon as their blood. The tree can be likened to the body of the human and other living things, and in general most trees have in them skin, fat, flesh, sinews, veins, blood, bones and marrow. The tree can be wounded and made to bleed, by cutting through its skin. Some trees, like the box, the cornel and the olive, only have a small amount of blood in their system. Some trees lack flesh or fat, some trees have no need for marrow or bones.
