Abstract
The objective of this study was to analyze the anatomy
of stems and roots of
Mnesithea selloana. Free hand cross sections
were made from fresh material of reproductive stems and adventitious
roots; they were colored with safranin and mounted on glycerin
jelly. Observations were made using an Olympus CH2 light microscope
and photographed. In cross section, the stems were circular
towards the distal end of the synflorescence and semicircular toward
the proximal end, and have two ribs. A uniseriate, continuous
epidermis presenting a smooth and thick cuticle and no hairs was
observed. Parenchyma cells increased in size towards the pith; they
have slightly thickened walls close to the epidermis and thin, nonlignified
walls near the pith. Vascular bundles formed an atactostele,
with 3-4 concentric rings; externally, small bundles enclosed within
a continuous ring of sclerenchyma, and toward the center larger
bundles without the ring were observed. The pith was hollow. The
roots presented rhizodermis with unicellular hairs, exodermis with
markedly thickened walls, aerenchymatous parenchyma with well
differentiated aeriferous spaces, and endodermal cells with markedly
thickened inner tangential walls. The vascular cylinder presented a
uniseriate pericycle, with polyarch structure exhibiting between 13
and 16 xylematic poles, and pithy parenchyma.
