If we wish to recognize the law according to which the tree is built up out of its parts as a compound harmonious' whole, we must first resolve the representation of the wholtf into that unit which lies at the foundation of its superstructure. This we have already done, to some extent, in the two previous chapters. Taking the tree, in the most extended signification of the term, as a separate individual or unit with reference to a forest, we have shown that this individual tree consists of a number of individual plants of a highly composite character called branches, which differ from the entire tree itself only in the smaller scale oa which they are constructed, and which actually prefigure thtf amount of growth of that tree at an earlier stage of its life; These branches are formed by a union of yet simpler individuals called shoots, and the shoots themselves are built up by phytons or leaves, individuals or units which rank still lower in the series. In this manner we have been led to the leaf as the fundamental organ in the building up of the tree-form. : '; ; .'i- 'i," ''.' !:iJ.'i,. -:: ';";ivr But this analysis may be carried much further.
