SUMMARY The taxonomic history of the desmid genera Onychonema Wallich, Sphaerozosma Corda and Teilingia Bourrelly is reviewed. In addition, Teiling's studies on asymmetry applied to Onychonema and Sphaerozosma are considered. Observations based on SEM examination of one species each of Onychonema and of Sphaerozosma are presented to show morphological differences. Finally, an appraisal of the taxonomic proposals by Telling and Bourrelly is given.
