The following parts, which we will name, are found in〈almost〉all plants, and admit of growth and addition—namely, the root, the shoots, the stem, and the branches; these resemble the limbs of animals which include all the other limbs.

They are not found in all plants; and in some plants which have branches these are not permanent, but only last from year to year. There are plants which do not have branches or leaves, fungi, for example, and mushrooms. Branches are only found on trees. Bark and wood and the pith of a tree are produced from moisture; some call this pith the womb of the tree, others the vitals, others the heart.

Of plants some are trees, some are midway between trees
