Wild cinnamon (Canella winterana) is a hardwood tree of restricted distribution in the jungles of Calakmul, Campeche, where it is little known, but with ample timber and non-timber potential. The objective of this study was to characterize and relate the floristic composition associated with the population of C. winterana in the forests of Calakmul. For this purpose, the composition of the floristic community associated with C. winterana was identified; 10 sampling sites similar to those of the National Forest and Soil Inventory (Infys by its Spanish acronym) utilized in Mexico were established. Ecological, ordination, and proximity indices between tree communities were calculated based on similarity in their composition by NMDS and UPGMA, using PAST 4.07. In addition to C. winterana, 121 tree taxa were identified; most of the individuals of this species were located in medium to low alluvial plain forests and medium sub-evergreen forests, on lithic or mollic leptosols and vertisols. Its distribution pattern was aggregated. The reproductive trees averaged heights of 8.7 m and normal diameters of 15.8 cm. The fruits weighed 0.34±0.06 g, with six seeds on average, which reached an average weight of 0.04±0.001 g. In conclusion, two forest types and three soils associated with C. winterana were identified, as were environmental and ecological attributes relevant to its presence in Calakmul, and it was determined that it is well integrated into the forest community of the region.
