Discussion:The cortical region of the inflorescence stem is notable for the occurrence of pockets (which run longitudinally in the exis) of collapsed parenchyma cells—like those which occur in a similar manner in the leaves of this species. The collapsed parenchyma pockets occur alternately with bundles of the outer circle. The remainder of the cortical region consists of globular parenchyma cells. The bundles adjacent to the outer margin of the sclerenchyma ring are not completely ensheathed by sclerenchyma, but have a few such cells at their phloem poles. A single layer of thick-walled sclereids forms the outer layer of the ring. Internal to this layer are several layers of lignified parenchyma cells. Just interior to these cells, in the periphery of the central zone of the central zone of thin-walled parenchyma, is a single ring of about 5 bundles.
