Allometry can be defined as the relations of size and shape of living organisms, arising from physical or physiological characteristics causing variations in the dimensions of the organism. In this context, this study aimed to investigate whether two species of the genus Byrsonima, which live under the same environmental conditions in the Roraima plow, have similar allometric characteristics. Biometric data were collected for the two species of the genus Byrsonima. For that, four plots of 0.25 ha were installed in a typical savanna area (non-forest), making up 1 ha of total sampling area. All individuals with a diameter greater than or equal to 2 cm were measured at a height of 2 cm from the base of the soil (DSH 2 cm ≥ 2 cm). Different values found in the height and stem diameter relationships indicate that the species B. crassifolia invests more in height as the stem diameter proportionally grows, while B. coccolobifolia has more retracted characteristics. This distinction indicates that it is supported by selection pressure associated with different paths of coevolution that both have been suffering over time.
