Abstract
TheAnabaena-Azolla association has proved to be an effective biofertilizer in tropical regions of wetland rice production. Three neotropical host species,A. microphylla, A. caroliniana, andA. mexicana, are similar in vegetative morphology (growth habits, frond dimensions, trichome cell number) and ecophysiology (relative heat tolerance). They were observed during our investigation to also be genetically alike and distinct from other taxa.
