BASIONYM: Navicula longicephala var. vilaplanii Lange-Bertalot et Sabater in Sabater et al. 1990

Navicula veneta

 

Navicula viridula

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Marina Potapova - October 2011
Length Range: 12-15.5 µm
Width Range: 2.5-3.3 µm
Striae in 10 µm: 20-24

Description

Valves are linear-lanceolate with very slightly protracted apices. The axial area is narrow and straight. The central area is small. The raphe is straight, with close proximal ends. Striae are strongly radiate around the center, becoming convergent at the apices. The areolae are indistinguishable under LM, approximately 50 in 10 μm.
