Figure 2 - Major types of arrangement of sclerenchyma found in the leaf cross-sections. In conduplicate leaf blades: A continuous ring B interrupted continuous ring C forming abaxial strands and an adaxial strand on the median rib D with an abaxial girder at the median vascular bundle. In flat leaf blades: E complete (abaxial and adaxial) girder at the first vascular bundles, abaxial girder at the second vascular bundles, third vascular bundles without associated sclerenchyma.
