Navicula recens


Navicula reinhardtii

LM scalebar = 10 µm = 80 pixels.


Contributor: Marina Potapova - August 2011
Length Range: 12-22 µm
Width Range: 4.5-5.3 µm
Striae in 10 µm: 14-16


Valves are lanceolate with protracted, subrostrate ends. The axial area is narrow and linear. The central area is small. Striae are radiate in the center and convergent at the apices, numbering 14-16 in 10 µm. Areolae are approximately 32-36 in 10 µm and hardly distinguishable in LM. Striae are bent in the middle of the valve. Short striae often alternate with longer ones around the central area.

The original description includes larger specimens with rostrate-capitate apices; we have not encountered similar specimens in North American collections.
