Phenology is a useful tool in the planning of multiple studies, ranging from the reproductive biology, fruit and seed collection, and diaspore dispersal. Through observations of phenological events, reproductive patterns can be easily characterized, which are relevant information for assessing the success of a species in a given environment. The phenology of Alibertia edulis was observed in two phytophysiognomies of the Cerrado Mato-Grossense: Cerradão and Cerrado sensu stricto, between February 2015 and January 2017, using the Fournier index. The phenophases of leaf fall, budding, flowering and fruiting were correlated with the environmental variables: maximum and minimum temperatures, relative humidity and precipitation. Leaf fall did not exceed 8% in the two evaluated locations. A. edulis showed vegetative growth in the rainy season between December 2015 and January 2016 and between September 2016 and November 2016. Flower buds occurred in December 2015 and November 2016 in both areas. Flower opening occurred in December 2015, and November and December 2016. In August and September 2015, the highest rates of ripe fruit occurred in both areas, with values not exceeding 12%. In 2016 there was no fruit maturation. A. edulis is an evergreen species with budding influenced by rain. Its reproductive phenophases are influenced by precipitation, except for fruit maturation that occurs in dry and hot months. Individuals from the Cerradão area have considerable reproductive performance indices when compared to individuals from the Cerrado strict sense.
