This paper presents morphoanatomic characteristics of roots, cataphylls, leaves and scapes of Amaryllidaceae s.s. and Alliaceae s.s. species from Northeastern Brazil. The histological laminas were prepared following standard plant anatomy techniques. Among the organs studied, leaves and scapes were shown to be useful for the delimitation of groups in family, genera and species. Among the diagnostic characters are raised: the presence of biconvex scape is unique in Griffinia and Hymenocallis (Amaryllidaceae s.s.), epidermal cell with sinuous anticlinal walls in the leaves and scape occur only in Griffinia espiritensis e acute maple leaf only in Habranthus robustus. Zephyranthes candidula differs by having subcircular and unifacial leaves, Hymenocallis littoralis by having subepidermal strands of collenchyma in the scapes and above the vascular bundles in the leaves. The presence of latex is unique of Nothoscordum pernambucanum (Alliaceae s.s.).
