Abstract

This study presents the description of 35 Desmidiaceae-Chlorophytes (3 Actinotaenium, 31 Cosmarium and 1 Cosmocladium) found on roots, shoots and leaves of Hymenachne amplexicaulis (Gramineae) collected in a flooded savanna of Venezuela (Apure State, 07° 33' N, 69° 10' W). The aquatic environment is acidic, with low salinity and high macrophyte density. Of the 35 taxa reported in this work 26 are new for Venezuela (2 Actinotaenium; 23 Cosmarium and 1 Cosmocladium) and 4 are propous new to science: Actinotaenium venezuelense Salazar sp. nov.; Cosmarium protuberans var. semicircularis Salazar C. var. nov. y C. regnellii var. scrobiculosum Salazar C. var. nov.
