Each tissue has been described and discussed, illustrations included. The anatomical features of the adventitious roots exhibit a primary structure but some specific anatomical aspects occur. The blade possesses a typical homogenous mesophyll. The vascular bundles of the mid vein are well developed with an aleatory arrangement of the vascular bundles. The petiole and flower peduncle stele is composed of numerous vascular bundles, embedded in the ground tissue.
Mechanical tissue is poor developed in almost all studied plant organs. In the literature, studies concerning the vegetative organs anatomy of Spathiphyllum wallisii are sporadic and those concerning the flower peduncle and the modified leaf (spathe) almost lack. |
