Adventitious roots of rhizomes of the fern Microsorium scolopendria arise exogenously from apical initials which have their origin in the cell layer directly beneath the epidermis. Divisions of the apical initial and its derivatives produce the adventitious root apical meristem. Cells between the apical cell and the meristele of the rhizome develop into the root trace.
