Anatomy of flowering fronds: longitudinal sections through the median antero-posterior axis of the mother frond. (a) Daughter frond showing the developing male
and female floral organs in the floral cavity (FC) and its clonal daughters in the vegetative pouch (VP). Arrow indicates a scar of the stipe. “N” represents the nodal strip of
cells between the VP and the FC. (b) Developing male floral organ (MF) and female floral organ (FL) in the floral cavity (FC). Note the daughter frond in the vegetative pouch
(VP) seemingly not attached showing that the floral cavity and the vegetative pouch are not on the same axis. Arrow-head shows the roof of the vegetative pouch which is
continuous with the upper epidermis. (c) Immature male floral organ depicting the stamen (Sm) with two anther lobes (A). Arrow indicates the two unconnected cell layers
which depict the overlapping flaps of the rim of the furrow arching the developing floral organs.
