Eunotia diadema

 

Eunotia exigua

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Paula Furey - March 2011
Length Range: 15-19 µm
Width Range: 2.4-2.6 µm
Striae in 10 µm: 23-24 in the center valve, 24-25 at the ends

Description

Eunotia enischna valves are small and slender. The ventral margin is concave, and the dorsal margin is convex. The apices are defined by a marked change in slope on the dorsal margin. The apices are capitate, rounded, and dorsally recurved. The raphe is short and curves on to the valve face. Striae are indistinct and radiate. The areolae are unresolved in the LM.
