Usually this leaf on the main stem falls before the branch attains much size, but its position is shown by the leaf-scar. The plant has- two classes of branches or limbs. The longer, ascending ones (Fig. 121) are sometimes called vegetative or primary branches, while slenderer or shorter branches on which bolls are attached directly by their flower stalks or boll-stems (peduncles) are called " fruiting limbs" (Fig. 122). The primary branches have also been. Fig.

Showing that the boll-stems are borne directly on the branch. called sterile limbs; this is because no boll-stem or boll is borne directly on these vegetative limbs, though boll-stems, with attached bolls, spring from the subdivisions of these main branches. In genera,l, a primary branch supports mmierous leaves, and, on its sub-branches, some bolls; while a fruiting limb usually bears several bolls and but few leaves. Normally, two branches arise from the axil of a leaf on the main stem (Fig. 123). One of these twin branches, arising from the same node of the main stem, is a fruiting.
