Berkshire Community College Bioscience Image Library
Both the upper (adaxial) and lower (abaxial) epidermis are uniseriate and contain chloroplasts. The air exposed adaxial epidermis is well cutinized and contain numerous stomata that open into large substomatal air chambers. The submerged abaxial epidermis has a very thin cuticle and lacks stomata. Dark staining slime glands are present on the abaxial surface.
The mid rib area is supported towards the abaxial surface by a wide wedge of supportive collenchyma.
