Resumen:
The objective of this study is to realize an analysis of the typology of the inflorescences in Scleria. The majority of species studied   present a main florescence; Scleria reticularis and S. melanomphala  present truncated inflorescence. The variations are related with the grade of development reached by the different parts of the paracladial zone. In Sect.  Scleria are encountered  the major inflorescence variability. The change of spikelet sexuality can occur toward the distal parts. There are variations in the distinct species with respect to the hierarchy of the paracladia where the change occurs. Future investigations should center their attention on the ontogenetic aspects of inflorescence development of Scleria; integrating these results, together with those of adult inflorescences, into taxonomic and phylogenetic investigations.
