BASIONYM: Nitzschia desertorum Hustedt 1949
LM scalebar = 10 µm = 80 pixels.
Observations
Contributor: Pat Kociolek - March 2011
Length Range: 13-22 µm
Width Range: 3-4 µm
Striae in 10 µm: 25-26
Description
Valves are elliptical-lanceolate with short, rostrate, narrowly round apices. Fibulae small, but distinct, 14-16 in 10 µm. Striae are punctate and resolvable with LM.
Krammer and Lange-Bertalot (1988) note that the central two fibulae are equidistant from one another, but this is not evident in the US populations. North American populations are more narrow than indicated by Krammer and Lange-Bertalot.

Compare
This species is similar in shape to N. compressa var. vexans, another species, like N. desertorum, described from the Middle East. Nitzschia desertorum is more linear, while N. compressa var. vexans is more angular and has the same number of striae as the number of fibulae.
