The inflorescence-axis bract is distinctive in that the ground tissue consists of sclerenchyma, more nearly thin-walled halfway between the surfaces of the bract, which contains pockets of parenchyma, possibly chlorenchyma. In addition to the main series of veins, a few smaller veins are adjacent and exterior to the parenchyma pockets. They have the same collateral orientation as the main veins. The inflorescence bract (fig. 22) is not dissimilar in structure, although it has more thick-walled sclerenchyma, definite chlorenchyma, and bundles adaxial to the chlorenchyma.
