Fig.
5.3-10. Water lily leaf. The object with the odd shape between the
vascular bundle and the palisade parenchyma is the body
of an astrosclereid. It does not look much like an astrosclereid
because the microtome has cut away all its arms, leaving just the round white
areas (arrows; white because we are looking all the way through the sclereid). If you
have the chance to examine your own slides of water lily leaves, you will see
many sclereids like this, and also you will see just short pieces of red tube
– the arms whose body has been cut away and is in a different section.
