Pujana, Roberto R. Burrieza, Hernán P Silva, Mariana P. Tourn, Graciela M. Castro, María A. Secondary xylem endemic Fabaceae Argentina. Xilema secundario endémico Fabaceae Argentina. Wood anatomy of stem and rhizome of Sophora linearifolia, a rhizomatous plant endemic to centre Argentina, is described. Structural description of thin sections and macerations includes microphotographs of optical and scanning electron microscopy. Significant anatomical differences exist between secondary xylem of aerial orthotropic shoots and underground rhizome. Both organs have absent to indistinct growth ring boundaries, simple perforation plates, alternate and vestured intervessel pits and disjunctive parenchyma cell walls. However, stems have smaller vessels, longer fibres, partial storying (vessel elements and axial parenchyma) and narrower rays. Some anatomical characters of the rhizome suggest adaptations to its sinuous pattern of growth. The stem wood anatomy indicates a close relationship to Sophora sect. Edwardsia. Anatomía comparada de órganos vegetativos (tallo y rizoma) de Sophora linearifolia (Sophoreae, Papilionoideae, Leguminosae). Se describe la anatomía de madera de Sophora linearifolia, una planta rizomatosa endémica del centro de Argentina. La descripción estructural de los cortes delgados y macerados incluye microfotografías de microscopio óptico y electrónico de barrido. Se observaron diferencias significativas entre el xilema secundario de los tallos aéreos ortótropos y los rizomas subterráneos. Ambos órganos poseen los anillos de crecimiento poco marcados a ausentes, placas de perforación simples, punteaduras intervasculares alternas y ornadas y pared de células parenquimáticas disyuntas. Sin embargo, los tallos poseen vasos más pequeños, fibras más largas, estratificación parcial (elementos de vaso y parénquima axial) y radios más angostos. Algunos caracteres anatómicos sugieren una adaptación del rizoma a un patrón de crecimiento sinuoso. La anatomía del tallo indica una relación cercana con Sophora sect. Edwardsia.
