When the seed or spore of a Calamitc had taken root (and it is not unlikely that, like the very remarkable spores of the Equiseta, their seeds had Avings which expanded to waft them through the air when dry, and closed instantly when they touched the damp soil), it probably produced a little low whorl of leaves surrounding one small joint, from which another and another, widening in size, arose, producing a cylindrical stem, tapering to a point at the base. To strengthen the unstable base, the lower joints, especially if the mud had been accumulating around the plant, shot out long roots instead of leaves, while secondary stems grew out of the sides at the surface of the soil, and in time there was a stool of Calamites, with tufts of long roots stretching downwards, like an immense brush, into the mud (Fig. 37. See also Fig. 39). When Calamites thus grew Fig. -Erect Catamites {C. SticJcovii), sliovnng the Mode of GroivtJi of New Stems, and Forms of tJie Bibs. (C) ia).
