MICROMORPHOLOGICAL ACHENE FEATURES OF RHYNCHOSPORA (CYPERACEAE) IN THE GUIANAS, SOUTH AMERICA, BEARING ON THE DELIMITATION OF SPECIES AND SECTIONS.
As part of a taxonomic revision of Rhynchospora for the Cyperaceae volume of Flora of the Guianas (South America), achene (fruit) micromorphological features were found to be useful in circumscribing taxa at the species level and to a large extent helpful in classifying them at the sectional level as well. From the overall results of the study, eighty taxa including three infraspecific taxa in eighteen sections of Rhynchospora were circumscribed from the Guianas. A new section, Stipitatae, was provisionally proposed, seven taxa are new, and one infraspecific taxon was elevated to the species level.
