1109. From the same cause, or by the influence of water on different situations in the earth, the root has branches. But as this influence is weaker than that of air and light, so the number, density, and length of the roots is less.
1110. The polarization of the tracheal fascicles into branches takes place all around the stalk in one situation. The influence is equal upon all sides. The idea of the formation of branches is the star. All branches have a radiate position around the stalk--all form a verticillum or whorl.
1111. Every other position of branches is only an alteration of the verticillate arrangement.
1112. In most plants the arrangement of the branches admits of being reduced to the spiral line. This position is only the verticil drawn out.
1113. This drawing out takes place through the continued growth of the stalk, in which the bundles of tracheæ, doubtless by the varied operation of light, develop themselves in order, become individualized, and issue from the stalk as branches.
1114. The crucial position of the branches depends upon the same growth of the stalk, but one in which transverse polarities are present. The irregular or dispersed position is most probably the last completion of the spiriform.
1115. The spiriform arrangement stands in relation with the formation of the tracheæ.
1116. The branches of the root observe no such regularity, partly on account of weaker polarity, partly on account of the obstacles placed in their way, at one time by the impenetrable earth, at another by want of water.
1117. The more the stem is differenced, so much the higher is it developed. Thus the richer in number the branches, by so much the more perfect is the stem. The stelliform branches belong to the first development. The plants, that have this arrangement, stand lower in the scale. To this the crucial appears to succeed, as a mediate position between the former and that which follows. The spiriform ranks higher. In it the stem is manifestly differenced more multilaterally. The dispersed arrangement appears to be the highest, because in it the greatest freedom prevails, because the poles have acted on every part of the plant, because they are everywhere in the air and in light. Plants with dispersed branches are organized air; without branches they are organized water as well as earth. Those plants only which have circles of tracheæ or rings of wood, as e. g. the Dicotyledons, ramify; these alone are, properly speaking, a conjunction by growth of many plants, and one that is truly persistent, or that bears fruit several times. The Monocotyledons being devoid of woody rings, do not, or but very rarely, ramify. Most of them therefore die off after they have once produced fruit. The ramification is a multiplication of the plant, in which the buds continue to stand upon the old stem.
