The present study investigates the reproductive phenology of a natural population of Maytenus ilicifolia Mart. ex Reissek from the Mixed Ombrophylous Forest (Araucaria Forest). The phenological study was carried out from April 2003 to March 2005, on 78 adult trees. The intensity of phenological events was estimated based on the scale of Fournier. The population showed seasonal behavior. A significant correlation was observed between temperature, day length and flowering. Two floral types were identified, one pistillate and the other staminate, and together with the phenology patterns results a dioecious characteristic for the species is suggested.
