In such forests grow also char- acteristic societies of herbaceous plants. The thicket, composed of small woody plants, such as Willows, Birches, Alders, Hazel bushes, etc., is another woody mesophytic society. The most remarkable of the mesophytic societies are the rainy tropical forests, where, due to a heavy rainfall .and great heat, vegeta- tion reaches its climax, and gigantic jungles are developed, com- posed of trees of various heights, shrubs of all sizes, tall and low herbs, all bound together in a great tangle by vines and covered by numerous Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Martin, John N.
