Se describe la morfoanatomía y arquitectura foliar de una población de S. areira L. de la localidad de El Cadillal (Tucumán). Se procesó el folíolo medial. El material fue fijado en FAA y se utilizaron técnicas histológicas convencionales. S. areira presenta hojas compuestas, subcoriáceas, alternas, imparipinadas o paripinnadas, raquis subcilíndrico. Los folíolos son simples de lámina lineal-lanceolada, ápice agudo y cur vado, base cordada asimétrica, margen liso-serrado. Venación, pinnada-camptódroma-cladódroma. Presenta mesófilo isolateral, epidermis anfiestomática de cutícula delgada y lisa. Aparato estomático ciclocítico. Tricomas glandulares. Hipodermis abaxial y adaxial continua o no. Idioblastos cristalíferos y tánicos. Canales esquizo-lisígenos resiníferos asociados al floema. Pecíolo circular en su extremo distal y subcircular en proximal, el mismo presenta epidermis e hipodermis, uniestrata; clorénquima en empalizada; sistema vascular formado por haces colaterales cerrados dispuestos en forma de U, con casquetes de fibras y canales secretores asociados al floema. Médula parenquimática.
The architecture and leaf morpho-anatomy of a S. areira L. population from El Cadillal (Tucumán) is studied. The medial leaflet was processed. The material was fixed in FAA and conventional histological techniques were used. S. areira presents compound, sub-coriaceous, alternate, impari-pinnate or pari-pinnate leaves with subcylindrical rachis. Leaflets presents linear-lanceolate blade, acute curved apex, asymmetrical cordate base, serrate-smooth margin. Camptodrome-cladodrome-pinnate venation. Isolateral mesophyll, amphistomatic epidermis with thin and smooth cuticle. Cyclocitic stomatal apparatus. Glandular trichomes. Abaxial and adaxial hypodermis continuous or not. Crystal and tannic idioblasts. Schizo-lysigenous resinsecretory ducts associated with the phloem. Petiole, circular at its distal end to subcircular at its proximal end, presents uniseriate epidermis and hypodermis; palisade clorenchyma; vascular system formed by collateral bundles arranged into U form, with secretory ducts and fiber caps associated with the phloem. Parenchymatous pith.
