Morfoanatomia de Memora nodosa (Silva Manso) miers, bignoniaceae

Resumo

Memora nodosa (Silva Manso) Miers, Bignoniaceae, is a Brazilian Savannah plant, popularly used as external wound and ulcer healing (leaves and stems). The goal of this research was to perform the morphological study of M. nodosa species and the anatomical study of its leaves. The morphological study was done to the naked eye and with the aid of a stereoscopic microscope. For the anatomical study leaves were sectioned and histological slides made in accordance with conventional techniques. Memora nodosa is a shrub with decussate leaves recomposed, bipinnate, imparipinnate with small leaflets, lanceolate, dark green and shining. The inflorescence is racemose with infundibuliform flowers and gold yellow corolla; nectar glands are observed in the upper third calyx; androecium with four fertile stamens, didynamus and one staminode; gynoecium with terminal style, superior ovary, seated on a nectary disc. The fruit is flattened septifragal capsule with winged seeds. Anatomically, the blade leaflet is hypostomatic with predominantly paracytic stomata. The palisade parenchyma is pluriseriate, occupying about two thirds of the dorsiventral mesophyll. Glandular and non-glandular trichomes are observed in greater numbers in the young leaves.
