Description:
Valves linear-lanceolate with slightly protracted, mostly acutely rounded ends (L 20-33µm, W 5,5-6,5µm, 16-18 striae in 10µm). Axial area narrow, linear. Central area elliptical to almost circular. Raphe straight, filiform with slightly deflected, distinct central pores. Terminal fissures hook-shaped. Transapical striae weakly radiate in the middle to even parallel, more parallel to convergent towards the poles. Voight discordances present. In SEM, lineolae densely spaced, 40-45 in 10µm.

Notes:
Found in several soil samples taken from cliffs bordering the ocean.So far only found on Ile de la Possession.Several taxa bear some resemblance to this population. Navicula veneta Kützing has a different number of striae bordering the central area while Navicula lundii Reichardt has a very clear asymmetrical central area. It is possible that further research will show that this is a new taxon.
