    . The other three species are probably introduced. Three species of the resting 11 are only known from neighbouring countries in South America, but have not been recorded from Venezuela. For each species a morphological characteristic with key for determination is given and geographical and ecological distribution is shown. Phytosociological relevés have been recorded. Four associations are recognized.
