Summary and Conclusions
The root apical organization of two species ofXyris has been investigated.
The structural configuration shows discrete initials for plerome and rootcap and a common tier of initials for the epidermis and cortex.
The cell complexes are analysed.
The endodermis arises from an endodermis-periblem complex.
Cyto-physiologically there is a quiescent centre to the tip of the root body with the real histogenetic zone, named the meristematic zone, surrounding it. The characteristics of these two zones are described.
