FIGURE 5 in Opuntia delafuentiana (Cactaceae: Opuntioideae), a new xoconostle from central Mexico

FIGURE 5. Micromorphologic differences of four species of Opuntia producing xoconostles. Images from the scanning electron microscope of the epidermic cells in spines of the apical and middle part. A. O. joconostle, apical part of the spine with epidermic cells very short and wide. B. O. joconostle, middle part of the spine with epidermic cells of 88.58 μm long and 16.98 μm wide, epidermic cells with fissures between each other and smooth texture. C. O. joconostle, glabrous epidermis, anticlinal walls with rugose texture and paracytic stomata. D. O. matudae, apical part of the spine with short and narrow epidermic cells. E. O. matudae, middle part of the spine with epidermic cells of 105.01 μm long and 21.20 μm wide, epidermic cells with fissures between the cells and smooth texture. F. O. matudae, glabrous epidermis, anticlinal walls with rugose texture and paracytic stomata. G. O. oligacantha, apical part of the spine with long and narrow epidermic cells. H. O. oligacantha, middle part of the spine with epidermic cells of 87.19 μm long and 10.10 μm wide, continuous epidermic cells without fissures between the cells and rugose texture. I. O. oligacantha, pubescent epidermis, anticlinal walls with rugose texture and paracytic stomata. J. O. delafuentiana, apical part of the spine with epidermic cells long and wide. K. O. delafuentiana, middle part of the spine with epidermic cells of 92.02 μm long and 10.76 μm wide, continuous epidermic cells without fissures between the cells and rugose texture. L. O. delafuentiana, pubescent epidermis, anticlinal walls with smooth texture and paracityc stomata.
