Resumen:
Five trees with morphological and isoenzimatic features intermediate between those of the deciduous species N. antarctica and the evergreen N. dombeyi were found in two separate communities within Parque Nacional Nahuel Huapi, Argenina. The major characteristics morphological and isoenzimatic of the putative hybrids and their parental species were described.  The putative hybrids were intermediate between both species in some characteristics like leaf vernation, outline and foliage persistence and for other morphological traits, the putative hybrids resembled one of the parental species or differed from both species. Isoenzymatic and morphological data sets support the idea of the hybrid nature of the semi-deciduous trees found. This is the only reported case of putative hybrids between a deciduous and an evergreen Nothofagus species developed in natural communities.
