Discussion
Variables within a single inflorescence axis of Abolboda include the relative presence of photosynthetic tissue and the thickness of the sclerenchyma ring. Chlorenchyma appears to be absent from those portions of the axis most distal and most proximal to the base of the plant. Chlorenchyma, where present, consists of nearly spherical cells; some may be somewhat elongate radially, and form a palisade. If chlorenchyma is not present, parenchyma cells polygonal in outline in transaction (elongate in longitudinal section) extend from the epidermis to the sclerenchyma ring. If chlorenchyma is present, a single layer of non-photosynthetic parenchyma is often present outside the sclerenchyma ring. If chlorenchyma is present, a single layer of non-photosynthetic parenchyma is often present outside the sclerenchyma ring, particularly at those points where bundles are adjacent to the outer face of that ring. The sclerenchyma ring consists of several layers of thick-walled lignified cells. The outermost may have much thicker walls than layers internal to it.
