The organism described is highly flattened and asymmetrical, with a firm pellicle that maintains a consistent body form. It exhibits prominent longitudinal or oblique striations and possesses a flagellum and stigma. Chromatophores are green, discoid, and lack pyrenoids, indicating a holophytic mode of nutrition. Typically found in freshwater environments, this organism’s cell structure is rigid and ovate when viewed from the front, often featuring a short caudal process that is notably compressed and twisted. The periplast is adorned with longitudinal striae or rows of short spines. Chloroplasts are numerous and disc-shaped, while paramylum bodies are few, large, and ring-shaped.
