Anatomical study of species from savanna-like formation, Anemopaegma arvense (Vell.) Stellf. ex de Souza (catuaba), Zeyheria montana Mart. (bolsa-de-pastor) and Jacaranda decurrens Chamisso (caroba) - Bignoniaceae

The anatomy of three medicinal species belonging to the Bignoniaceae family, from savanna-like formation and in risk of extinction, was studied. They were: Anemopaegma arvense, Jacaranda decurrens and Zeyheria montana, from Botucatu. Hand-made transversal sections of stem, foliar leaf and petiole and paradermal sections of foliar leaf, differentially stained with alcian blue and basic fuchsin, were studied and described anatomically. The three species show anatomical adaptations to xerophytic environment, expressed by compaction of foliar mesophyll, thickened cuticle (Anemopaegma and Jacaranda) and acquisition of abundant non-glandular trichomes (Zeyheria).
