Discussion
The two sections shown (figs. 18, 19) illustrate a great deal of difference between the median region and the most apical portion of an inflorescence-axis bract. At the lower level (fig. 19), the mesophyll contains sclerenchyma on the adaxial face, and a few bands of such tissue on the abaxial face. Chlorenchyma and non-photosynthetic parenchyma form bands within the bract. At the highest level (fig. 18), the entire mesophyll consists of thin-walled sclerenchyma.
