The daughter fronds are produced by vegetative budding in this special sac and are held inside with the help of a stipe which connects them to the mother frond(Fig. 2b and c). The stipe is continuous with the ventral epidermis of the daughter frond and as the daughter frond grows the cells of the stipe elongate over their antero-posterior axes (Fig. 2b). The daughter fronds are released (Fig. 1d and i) through the opening of the vegetative pouch after detachment from the stipe. The remnants of the stipe are left inside the pouch (Fig. 2a). Just below the opening of the pouch on the ventral surface, the frond retains a prominent scar at a position where the connection to the stipe from its mother existed before (Fig. 1i). It is also evident as a rupture on the ventral side of the frond as depicted in Fig. 2c.
