Overview

Excerpt from Memoirs of the Museum of Comparative Zoology, at Harvard College, Vol. 16 These processes termed knees evidently serve very much to extend the area over which the tree can maintain itself. There can be little doubt that bv it the tree has gained access, to at least thirty thousand square miles of area in the southern part of the United States, from which it would otherwise have been debarred. I have been unable to find any account of other species of trees having such knee-like processes. Several species of our ordinary timber trees are apt to make nodulose projections from their main roots; and when they grow in swampy ground are apt to keep their roots rather near the su'r face; but none of them have developed such specialized structures as are found in the Taxodium, and none of them have anything like the power of adapting themselves to such varied conditions of humidity. So far as is known to me, the Taxodium is the only tree that is able to occupy positions varving from very wet swamps to rather dry uplands. It is not too much to say that its range of station, so far as actual conditions go, is about double that of any other forest-tree belonging to the North Amer ican flora.
