As the foot or support is not in this case the continuation of a single axis, but is made up of a num- ber of successive branches superposed, these forms are said to be sympodial, the prefix in this term having the same sig- nificance as in " syn- carpous" and the like, and implying that the foot is composed of several coherent parts. In these cases, then, we have a sympodial monopodium. 145. Dichotomous Branching. In this system the growing point at the apex of the stem divides into tioo new grooving points, both of which are, therefore, terminal and not lateral, as in the first mode. The growing points of the branches, in their turn, are each converted into two new ones, as shown in Fig. 131. As in the monopodial mode, there may be helicoid and scorpioid dichotomy, due to the superior development of the growing points on. Fig. 133. Fig-. 132.
