Styloid calcium oxalate crystal idioblasts of Agave americana L. are suberized. Where the crystals do not touch the cell wall directly they are enclosed in a suberinic sheath which is connected with the suberinic wall layer. No polysaccharides are laid down as a tertiary wall layer, nor could any polysaccharides be found in the crystal sheath. These results contradict those of Arnott (1973) but agree fully with those of Rothert and Zalenski (1899).
龙舌兰属植物石细胞中的草酸钙晶体异形细胞被木质化。当晶体不直接接触细胞壁时，它们被包裹在一个与木质层相连的木质鞘中。没有多糖沉积在三级细胞壁中，也没有在晶体鞘中发现任何多糖。这些结果与 Arnott（1973）的结果相矛盾，但与 Rothert 和 Zalenski（1899）的结果完全一致。
