The section of a petiole of a leaf taken from the same plant is shown in fig. 171, C, and the structure of the section closely resembles that of the rhizome. There were eight bundles arranged in a circle, within which were two medullary strands. The cortical region was composed of several rows of brownish cells, prob- ably similar to those in the outer part of the rhizome, and within these, separated.
