Morphometric data, hypsometric ralationship between diameter and height, and equations of shape factor, commercial shape factor and formal height for Cabralea canjerana, in native secondary  forest  in  RS  are  shown  in  this  paper.  Keylwerth’s,  Petterson’s  and   Pollanschütz’s modelss were tested for hypsometric ralationship in three different stages of the forest development. Näslund’s model was tested for all trees by using the stepwise regression procedure. Following the same procedure, Pollanschütz’s model was used for the shape factor and commercial shape factor, and Kennl’s model was used for the formal height. The sums showed that Cabralea canjerana shape factor depends only on its height and commercial shape factor is a function of its height and BHD. Four out of nine of Kennel’s equation coefficients were significant to 95% level of probability. Näslund’s model was the most appropriate to discribe the hypsometric relationship of the studied species.
