In both genera with the next leaf, thealternate condition sets in which persists through life. There is no important difference in the microscopic structureof the petiole of a leaf of the whorl and of the fifth leaf: bothin section about the middle exhibit (see fig. 11) a ring ofnormal cortex enclosing a ring of sclerenchyma within which isphloem and xyleim and an included bundle with the xylem towardsthe face of the leaf as drawn. Associated with the largest xylemvessels are resin ducts to the number of five. Close under the blade,
