The epidermal structure and ontogeny of stomata in vegetative and floral organs of Hibiscus rosasinensis are described.
The epidermal cells are polygonal isodiametric or elongated and arranged irregularly or parallel to the long axis. The anticlinal walls of the epidermis are thick, straight, arched, or rarely sinuous. The surface of the cuticle shows parallel striations radiating from the guard cells or hair bases.
Six types of glandular and eglandular trichomes have been noticed.
The mature stomata are anisocytic, paracytic, or anomocytic. The development of anisocytic and paracytic stomata is of the mesogenous or syndetocheilic type. The ontogeny of anomocytic stomata conforms to the perigenous or haplocheilic type. The three types of stomata occur on all the vegetative and floral organs of this plant except the anther wall and the outer epidermis of the carpel.
The developmental modes are constant from organ to organ within the same plant.
