Two plots were sampled, one dominated by Quercus costaricensis and the other by Q. copeyensis, and in each 144 quadrats measuring 1 x 1 m were analysed. Cover of all vascular taxa and several biotic and abiotic parameters were recorded in each quadrat. A floristic analysis for species, genera and families, and phytogeographical spectrum are given, followed by a discussion of dominance structure and horizontal distribution. About 60 percent of the taxa tended to be distributed in clumps. Quercus costaricensis and Quercus copeyensis associations were distinguished within the two plots by identifying three diagnostic and five characteristic taxa for each. The similar ecological conditions of the vegetation in both forest associations were further emphasized by the non-floristic analyses.
