Ozerova L. V., Timonin A. C., Structure of the chlorenchyma in the persistent terete leaves of Austrocylindropuntia subulata (Muehl.) Backeb. (Cactaceae): anatomy beyond functional limitation, Wulfenia, 2020, 27:221-232
A microscopic analysis of the persistent, cylindrical leaves of Austrocylindropuntia subulata. It describes outer palisade parenchyma and inner non-palisade parenchyma, mucilage idioblasts and the arrangement of vascular bundles. The discussion concerns the combination of assimilation and water storage in the same tissues.
