BASIONYM: Nitzschia brevissima Grunow in Van Heurck 1881
LM scalebar = 10 µm = 80 pixels.
Observations
Contributor: Pat Kociolek - September 2011
Length Range: 20-55 µm
Width Range: 3.5-5.5, as measured in the middle of the valve µm
Striae in 10 µm: 37-39
Description
Valves are broadly linear with concave, protracted margins. The valves are distinctly to slightly sigmoid, a shape produced by the ends being bent in opposite directions. The apices are narrowly rounded. A keel is located at the valve margin, with very distinct fibulae. Fibulae number 5-8 in 10 µm. Striae are barely visible with DIC or oblique lighting.
