Rhizosolenia

Rhizosolenia are centric diatoms, approximately 20-70μm in diameter for R. styliformis and 4-20μm in diameter for R. setigera. These long, thin cells are generally solitary or found in short chains. The ends of the cells are short and needle-like. Many small chloroplasts are located throughout the cell.

Rhizosolenia are found in temperate waters.
