Seasonal development in saltcedar (Tamarix pentandra Pall.) of clado-phyll cuticle thickness, vessel member, and callosed sieve plate areas was measured. Anatomy of cladophylls was compared to that of leaves. Leaf anomalies were salt glands and reduced chlorenchyma. Cladophyll anomalies included sunken salt glands and subepidermal deposition of Sudan IV-staining substances to a depth of ca 50/i. Diameters of vessel members and callosed sieve plates appeared to be similar to those of other dicotyledonous woody species.
