Schinus areira is a naturalized tree in northwestern and western Argentina, and extensively cultivated in the country. Our goals were (1) to determine the floral and reproductive biology of S. areira, (2) to compare different pregerminative treatments, and (3) to analyze the morphology of the seedlings during the development for their correct taxonomical identification. Analyses of floral biology and reproductive system, fruit and seed morphology, and different pregerminative treatments were carried out. Seedlings development was recorded at 90, 180, and 270 days. As a result, it was found that the fruit/flower ratio was very low or low, and the pollen/ovules ratio was very high. On the other hand, pregerminative treatments gave very low results that agree with fruit morphology. Seedlings had a normal growth reaching an average of 43 cm height at 270 days, and they developed simple basal leaves with a compuond leaves from approximatelly 180 days. We proposed that the species is dioecious and polygamomonoecious, mainly gynomonoecious, the pollination is ambophyly with predominance of entomophyly, and the seedlings development is phanerocotyledonar epigeous. Schinus areira L. es un árbol naturalizado en el noroeste y oeste de Argentina y extensamente cultivado en el país. Nuestros objetivos fueron (1) determinar la biología floral y reproductiva de S. areira, (2) comparar diferentes tratamientos pregerminativos par la especie y (3) analizar la morfología de las plántulas durante el desarrollo para su correcta identificación taxonómica. Se realizaron análisis de biología floral y del sistema reproductivo, de morfología del fruto y semilla, y diferentes tratamientos pregerminativos. Se registró el desarrollo de plántulas a los 90, 180 y 270 días. Como resultado se obtuvo que la proporción frutos/flores fue muy baja o baja, y la proporción polen/óvulo muy alta. Por otro lado, los tratamientos pregerminativos dieron resultados muy bajos lo cual concuerda con la morfología del fruto. Las plántulas tuvieron un crecimiento normal alcanzando un promedio de 43 cm de altura a los 270 días, y desarrollaron hojas basales simples con hojas compuestas a partir aproximadamente de los 180 días. Se propone que la especie es dioica y polígamo-monoica, mayormente ginomonoica, la polinización es ambófila con predominio de entomofilia, y el desarrollo de las plántulas fanerocotiledonar epígeo.
