Aspectos morfo-anatômicos dos folíolos de Swartzia Brachyrachis Harms Var. Snethlageae (Ducke) Ducke e Swartzia Laurifolia Bentham, Leguminosae Adans. (Caesalpinioideae Kunth), ocorrentes na Ilha de Algodoal-Maiandeua/Pará

Abstract

The descriptive study morphological and anatomical of the Swartzia brachyraquis var. snethlageae (Ducke) Ducke and Swartzia laurifolia Bentham, was developed in the sandcoast of Algodoal-Maiandeua/Pará. The objective this work was study the morphological and leaflets anatomy, to assist the taxonomy and Know the possible adaptation of there species when submetted to saline environment.To the morphology and anatomy study, it was used technics usual in morphological and anatomical studies. The result showed differences about: consistency, blade and apex, these features observed in the leaflets was used to distinguish the taxa. Were observed commons anatomicals features between the species as: thickned epidermis and cuticle, paracytic stomata, non glandular, uniseriate simple hairs. Features as vein net and vascular termination are considered as distinguished features for the species. Acording to the morphological and anatomical analysis, we can conclude that these species are perfectly adapted to the sandcoast ecosystem, and developed probablely anatomycals adaptation to environment.
