【 摘 要 】

Dodonaea viscosa Jacq., Sapindaceae, is a plant traditionally used as anti fever, anti- rheumatic and antimicrobial. This work determined morpho-anatomical parameters, by macro and microscopic analysis of Dodonaea viscosa leaves, aiming to reach their diagnosis as pharmaceutical input. Macroscopically, the leaves have a lanceolate shape limb, full margin, rough consistence and venation eucamptodromous. The petiole is short, straight and in transversal section it is triangular with round angles. Microscopically, the lenticullar formation cuticle is seen with prominence, the glandular thricomes are seen with four cells on the base, the non-glandular unicellular thricomes are seen with pointed apex, the higrophitic stomatas are disposed in the lower surface epidermis only, the palisade parenchyma show up to three-cell layers and vascular bundles with xylem involved by phloem and parenchyma lines which bound a central mass of parenchyma cells to a sclerenchyma sheath. This morph-anatomical characteristic, when analyzed in group, contributes to the botanical quality control of Dodonaea viscosa leaves as pharmaceutical input.
