- Draparnaldia is a genus of freshwater green algae in the family Chaetophoraceae. Draparnaldia are uniseriate; each filament is composed of a chain of cells arranged in one row. Chloroplasts appear as a band within the center of each cell. The length of the main axis cells are generally the same, regardless of whether or not they bear branches. These side branches are divided extensively into terminal hairs. The entire plant is enveloped in loose, slippery mucilage. Draparnaldia is a cosmopolitan genus with wide distribution and it is usually found in cold aerated waters. They are either attached to sand or grow epiphytically on other aquatic plants. Draparnaldia can be seen growing in clear streams trailing on stones and boulders . Herman S. Forest of The Southern Appalachian Botanical Club has stated that while not common, it is present frequently enough to be recorded in almost all local flora lists of green algae that have been compiled. A multitude of species are present in Lake Baikal, Siberia and have been described by Meyer and Jasnitzky. A species of the genus had been placed and described in the Linnean Herbarium as Conferva Mutabilis Roth in 1797. Nowadays Conferva is no longer used and the species is described as Draparnaldia mutabilis (Roth) Bory. Bory is added in honour of the researcher of the same name, based on whose description the genus was separated from similar appearing forms. Bory is accredited with the establishment of the genus.

- Draparnaldia est un genre of d' classé dans la famille des Chaetophoraceae ; Chaque filament algal est constitué d'une chaine linéaire de cellules en forme de tonnelets où les Chloroplastes forment une bande plus verte dans la partie centrale de chacune de ces cellules. La longueur des cellules de l'axe principal est généralement la même (qu'elles portent ou non des branches latérales). Les branches latérales se subdivisent en filaments se terminant chacun par un poil terminal (plus ou moins long selon l'espèce et l'environnement). La plante entière est enveloppée et protégée dans un mucilage lâche et glissant. (fr)
