A parenchymatous cortex underlies the epidermis, with endodermis (Figure 2D) devoid of Casparian strips and starch.
At the costa, there is a central, parenchymatose area, surrounded by an endodermis with Casparian strips, with conducting tissues; xylem assumes the shape of an open V, and scarce phloem develops at the ends of the xylem arms.
The root primary growth (Figure 3A and B) shows irregular epidermis with thin-wall cells and unicellular hairs; cortex with unilateral or bisseriate exodermis of suberized wall cells, loose parenchymatic tissue with secretory ducts, and endodermis with Casparian strips; and central cylinder with parenchymatous uniseriate pericycle, phloem strands alternating with an equal number of xylem strands, provided with six to ten protoxylematic poles (polyarcroot) and parenchymatous pith.
