Mercado, María I.; Alberto Slanis; Ana I. Ruiz; Graciela I. Ponessa. 2014. “Morphoanatomy and Leaf architecture of Lithraea molleoides (Anacardiaceae)”. Lilloa 51 (2). Lithraea molleoides (Vell.) Engl. is a species, whose leaves have been reported to exhibit antimicrobial, antiulcerogenic, antiviral, cytotoxic, immunomodulatory and antioxidant activity. The aim of this work is to describe the leaf architecture for these species and to identify morpho- anatomical characters with diagnostic value and compare them with previous studies regarding to its variability depending on the environment it inhabits. The samples were processed by standard histological techniques. L. molleoides presents simple or compound, alternate leaves with sessile leaflets. Leaflets venation is pinnate, camptodromous brochidodromous, with intra-marginal secondary veins. Epidermis glabrous with polygonal cells with straight to slightly lobed walls. Smooth cuticle. Anomocytic and anomotetracytic stomata. Isolateral hypostomatic leaflets. The presence of drusen, rhomboid crystals and tannic cells are highlighted. Mid vein with 2-4 collateral vascular bundles with sclerenchymatic sheaths that encloses both xylem and phloem or only phloem, opposed to 1-2 minor vascular bundles with sclerenchymatous sheath. Phloem with tannic cells, usually interrupted by esquizogenous ducts. Semicircular winged rachis with structure similar to the mesophyll. Petiole, circular in section with vascular system consisting of 4-6 vascular bundles delimited by sclerenchymatic ring. This study concludes that L. molleoides presents a high phenotypic plasticity and describes for the first time the foliar architecture and anatomy of rachis and petiole; as well as it cites the presence of drusen, tannic cells and rhomboid crystals.
