Images are not scaled. An individual that looks bigger than its neighbors might actually be smaller. See approximate size via the Observations section below. All images were made to fit within an area of 360px high and 200px wide.
Observations
| Author: | Colleen Flanagan 2007 |
|---|---|
| Biovolume/cell | 114.48 |
| Length: | 30-40 µm |
| Width: | 2-4 µm |
| Striae: | 14-20 / 10 µm |
Description:
Cells appear similar to Fragilaira in that cells are elongated and have striae. However these are usually seen alone and not in groups.
Notes:
Green Lakes: Morphotype N. In Green Lakes, some of this taxon may be Synedra famelica.

Secondary Description
Author: Wehr, J. D. and Sheath, R. G., (eds.), 2003
Secondary Description:
Frustules are rectangular in girdle view. Cells are linear to lanceolate. There are two labiate processes per valve, on near each end. Many taxa have a prominent spine pair at each end, one on either side of the pore field. Cells often form colonies with cells attaching at a single point, either on substrata or in the plankton.
