Racemose branching is also the rule in the root and leaves of Phanerogams.

Such a system of branching is known as dichoto- Mous (see fig. 54). Similarly, though rarely, the branching may be TRICHOTOMOUS. In some cases the terminal bud of an axis or stem soon ceases to grow in length, and the lateral True Dichotomy buds immediately below it develop into strong branches or secondary axes. The terminal buds of these branches or secondary axes in their turn soon cease to grow in length, and lateral buds immediately below them develop into branches or tertiary axes, and so on. Such a system of branching is described as cymose. In cymose branching where two lateral buds only are developed, the branching takes the external form of dichotomy, but is not true dichotomy, inasmuch as the branches do not arise from the bipartition of the terminal buds. Such apparently dichotomous branching is therefore known as false dichotomy or DiCHASiUM (fig. 55, a). Similarly, there may be false trichotomy or trichasium. Katchampa {Plumeria acutifoHa), karancha(Car«>i-« Carandas), and krishna- kali or Marvel of Peru are good examples of false dichotomy; and karabi {Nerium odorum) is a good.
