Dioscorea bulbifera L. is commonly known in Brazil as inhame, cara-de-arvore, cara-do-ar, cara-moela, batata-do-ar, and cara-de-sapateiro. Pharmacological studies have demonstrated anti-nociceptive, cytotoxic, hypoglycemic, antimicrobial and cardiovascular activities. The present work was to carry out morpho-anatomical research of leaves, stems and tubers of D. bulbifera L. as a contribution to the quality control. The botanical material was investigated according to standard methods of light and scanning electron microscopy. D. bulbifera L. has leaves simple and varying sagitiform to cordiform in shape, uniseriate epidermis, amphistomatic leaves with anisocytic and anomocytic stomata. Non-glandular trichome was not observed and glandular trichomes occur on both surfaces. Glandular trichomes are capitate with multicellular head. The mesophyll is dorsiventral. Petiole is concave-convex with 3 conspicuous ribs and two ventral winged lobes; all ribs internally fill by angular collenchyma. The stems showed 8 ribs, cuticle striate, and mucilage idioblasts and a sclerenchymatic ring was present in the cortex. The tuber has several cork layers and the parenchyma cells accumulate several starch grains with irregular shape.
