Abstract

This paper presents an anatomical study of the structure of the roots, stems and leaves of Tradescantia pallida cv. purpurea. The tuberised root of this species has a primary structure, typical one for the herbaceous monocotyledonous plants. The stem also has a primary structure, with two concentrical rings of closed collateral vascular bundles. The structure of the leaf is a heterogenous one, with adaxial uniseriate epidermis, multiseriate hypodermis, uniseriate palisade mesophyll, multiseriate spongy mesophyll, and uniseriate abaxial epidermis. Leaves are dorsiventral, hypostomatic, with tetracytic stomatal complex. The epidermis presented non-ramified bicellular protecting trichomes and epidermal cells have anthocyanins in the vacuolar sistems. In the parenchyma and collenchyma of these vegetative organs, there are many calcium oxalate crystals, particularly tetragonal ones.
