Discussion:(fig. 51). Although inflorescence stems in this species are
larger in diameter than the above, they are not markedly different in most
respects. One notable feature is the occurrence of a single hypodermis layer. At
levels lower than that shown, two layers were apparent. A feature not previously
indicated is the presence of bundles (in addition to those at the outer margins
of the sclerenchyma ring) within the ring itself. Additional bundles are present
in the "pith" region. At lower levels, all bundles (except those at the outer margin
of the ring) are located in the thin-walled portion of the central ground tissue.
