FIGURE 5. Comparison of leaf morphology between Cryptochloa dressleri and C. stapfii. A. C. dressleri, adaxial leaf surface, with linear rows of bulliform cells (large arrow), and crenate (olyroid) silica bodies (CreSB). B. C. dressleri, abaxial leaf surface, with prickles (large arrow), crenate (olyroid) silica bodies (CreSB), and cruciform silica bodies (CruSB). C. C. stapfii, adaxial leaf surface with irregular rows of bulliform cells (large arrow) and crenate (olyroid) silica bodies (CreSB). D. C. stapfii, abaxial leaf surface without prickles, crenate (olyroid) silica bodies (CreSB), and cruciform silica bodies (CruSB). Specimens: C. dressleri (Stapf et al. 785, FT, PMA, SCZ), C. stapfii (Stapf et al. 865, FT, PMA, SCZ).
