Discussion:(fig. 50). At the level shown, the inflorescence axis is surrounded by a bract. This may account for the occurrence of lignified papillate epidermal cells. The cortical zone consists of spherical chlorenchyma cells. A number of bundles, each surrounded by an arc of sclereids, is present outside the sclerenchyma ring. The inner portion of the ring intergrades with the thin-walled parenchyma in the "pith" region. "Within this latter zone, several (about 6) bundles occur. These bundles are notable for the occurrence of a prominent protoxylem lacuna which is separated from the remainder of each bundle. An additional set of bundles is interposed between those just mentioned and the inner margin of the sclerenchyma ring at lower levels in the inflorescence axis, and presumably these bundles supply a bract, and are thus absent at the level shown.
