【 摘 要 】

The present work aimed to study the fitossociologic structure and floristic similarity among seasonal and mixed forests of Argentina and Brazil. Cruce Caballero Park with 522 hectares where the method of multiple plots was adopted with (20 x 10 m). In each plot all individual tree of size equal or heigher than 5cm diameter were registered, being measured the stem diameter and height into three environmental compartments, Haplorthox, Ustorthent and Udorthent. In Haplorthox,Araucaria angustifolia(Bertol.) Kuntze prevail at higher stratum andSorocea bonplandii (Baill.) W.C.Burger, Lanj. & Boer, Cabralea canjerana(Vell.) Mart.,Ocotea lancifolia MezandApuleia leiocarpa J.F.Macbr.follow it. In Ustorthent araucaria is absent andGymnanthes concolor Müll.Arg. ,Trichilia clausseniiC.DC. , Apuleia leiocarpa, Pilocarpus pennatifoliusLem. andSorocea bonplandiiprevail. Aracuaria is scarce in Udorthent whereParapiptadenia rigida (Benth.) Brenan, Alchornea triplinerviaMüll.Arg.,Luehea divaricataMart. , Erythrina falcata Benth.andMyrsine gardneriana A.DC.prevail. A comparative analysis shown Cruce Caballero more similar to seasonal forests than mixed araucaria forest from Brazil.
