Abstract

Albornoz, P. y M. Hernández, 2006. ?Anatomy and endomycorriza in Pellaea ternifolia (Cav.) Link subsp. ternifolia (Pteridaceae) in Tucumán (Argentina)?. Lilloa 43 (1-2). This paper describes the anatomy of leaves, rhizomes and roots It is valued the endomycorrhiza colonization. Fresh material was fixed in FAA. Conventional histological techniques were used. The anatomy of this subspecies evidences its adaptation to xeric environments. It is characterized by ericoide leaves, fibers and macroesclereids in all of the studied organs. The presence the endomycorrhiza in this subspecies is cited for the first time for Argentina and Tucumán. The rhizospheric espora are found: Acaulospora scrobiculata Trappe, A. gerdemannii Schenk and Nicolson, A. birreticulata Rothwell and Trappe, Glomus sp1, Glomus sp2 y Gigaspora sp.
