Abstract

The purpose of this study was to increase knowledge of the nitrogen-fixing cyanobacteria communities of Chilean rice
fields. To this end, we sampled 34 rice fields situated between latitudes 34° 30’ and 36° 36’ S in central Chile. At each site,
two water samples and one soil sample were taken. Samples were fixed in 4 % formalin before taxonomic determination.
A total of 12 filamentous heterocystous taxa were determined, nine of which have not previously been recorded in Chile.
For each taxon, a description based on morphological and reproductive characters was made and recorded along with
information on the geographical distribution in the study area
