- Chloroplasts visible inside cells are green or yellow-green
- Cells have constrictions between them
In this section
Pseudofilamentous desmid with adjacent cells joined in a slightly offset way, forming a spirally twisted chain. The filament is often embedded in mucilage. Each cell is comprised of 2 semi-cells, each of which contains an axial chloroplast with pyrenoids. In end view the cells may have 2, 3, or 4 processes depending on the species. Pairs of filaments may conjugate in the manner of Spirogyra.
