Seedlings of Tabebuia avellanedae Lor. ex Griseb. (“ipê-roxo”) and T. chrysotricha (Mart. ex DC.) Standl. (“ipê-amarelo”), arboreal species that occurr in the state of Paraná, southern Brazil, are morphologically and anatomically studied. Seedlings were obtained from seeds collected at the Universidade Estadual de Maringá, state of Paraná. Anatomical sections were handmade and stained with astra blue and safranin. Seedlings are phanerocotylar and epigeal. The root is axial and pentarch-heptarch in T. avellanedae and tetrarch-hexarch in T. chrysotricha. The root-shoot transition region occurs in the hypocotyl. Mesophyll cotyledonous is homogeneous in T. avellanedae and heterogeneous in T. chrysotricha. Eophylls are simple and dorsiventral leaves and metaphylls are compound and isobilateral. Eophylls and metaphylls are hypostomatic with anomocytic stomatal complexes and glandular and non-glandular trichomes
