Figure 12. Nymphopsis spinosissima. Section through a valved cuticular gland. Note the short microvilli at the apex of the gland cells. The nucleus at the upper right belongs to an epidermal cell, the one at the bottom to a gland cell. Epidermal cells invest the gland on all sides. A very thin extension of the cuticle serves as the duct (dark border between gland cells at the base of the valve opening). 9,500x
