Pinnularia
- Striae chambered, may form longitudinal lines
- External proximal raphe ends dilated, bent slightly
- Distal raphe ends deflected
Frustules of Pinnularia may be large, up to 300 µm in length. The striae are alveolate. Internally, the striae are positioned within chambers. The openings of the chambers are evident as longitudinal lines that cross the striae. The raphe system may be straight or complex. Externally, the proximal raphe ends are expanded and bent...
