Calymperaceae, a new family to the bryological flora of Uruguay

Abstract

Background and aims. The aim of this work was to increase the knowledge of the bryoflora in Uruguay based on the analysis of samples collected in Fortaleza Santa Teresa National Park (Uruguay). M&M. Specimens were collected, processed and analyzed morphologically using conventional techniques for bryophytes. Microscopic characters were observed and illustrated with light microscopy (LM) and scanning electron microscopy (SEM). Results. Calymperaceae Kindb. is recorded for the first time to the country, represented by Syrrhopodon gaudichaudii Mont. This species is characterized by leaves strongly crispate when dry, and margins smooth to dentate at the apex. Conclusions. A detailed description, illustrations with SEM and LM, and a distribution map of S. gaudichaudii is here presented.
