Abaxial epidermis papillose, or not papillose. Stomata mainly confined to one surface, or on both surfaces; where recorded anomocytic. Hairs of diverse forms recorded - unicellular, uniseriate, glandular and eglandular, peltate, stellate, etc. Adaxial hypodermis present, or absent. Lamina with secretory cavities (with canals in the phloem, but not noticeably ‘gland-dotted’). Secretory cavities containing resin. The mesophyll containing crystals. The crystals druses, or solitary-prismatic. Main veins embedded. Minor leaf veins without phloem transfer cells (Odina (= Lannea)).
