The results of an ultrastructural examination of leaf anatomy and cytology of plastids of both non‐Kranz and Kranz grasses are presented. Variations of Kranz anatomy examined include agranal and two granal conditions of kranz‐cell chloroplasts, details of the two typical parenchyma sheaths of Aristida , and the “distinctive cells” of species of some small panicoid tribes. These conditions are discussed in relation to C 4 photosynthesis, evolution, and classification.
