Resumo: | The Gymnanthes klotzschiana is a pioneer tree species characteristic of the alluvial plains of the Ombrophilous Mixed Forest, extremely important for the conservation of the riparian forests. Therefore, this work aims to analyze a structure and dynamics of Gymnanthes klotzschiana in a fragment of Mixed Ombrophilous Forest. The used came from a sensos at in the years 2007,2010 and 2013, located in the Botanical Gaden Campus of the UFPR, Curitiba –PR, Brazil, with a total area of ​​15.2 hectares. Measurements were performed at intervals of 3 years, and all trees with diameter at breast heitght (DBH) greater than 10 cm were measured and identified. The structural analyzes were performed based on the population parameters by species as proposed by Mueller-Dombois (1991); the dynamics was obtained monitoring the growth ingrowth and mortality between the measurement periods. The results show a constant increase of Gymnanthes klotzschiana between three measurements, going from 120 to 256 individuals ;as a consequente there was a considerable increasing af in basal area between measurements going from 3.26 m² to 6.2 m²/ha. An annual increment rate of 0.31 cm / year to 0.34 cm / year, and the periodic annual increment in cross-sectional area increased from 0.0280 m² / ha to 0.0397 m² / ha. There was a relative increasing for the coverage values and for the importance values between measurement. It is concluded that Gymnanthes klotzschiana has a high value of importance for a Mixed Ombrophilous Forest, as well as a dynamic that favors the development of other species.  Key-words: Branquilho, Growth, Horizontal structure, ingrowth, mortality.
