Pinnularia rabenhorstii

 

Placoneis abiskoensis

LM scalebar = 10 µm = 80 pixels.



Observations

Contributor: Marina Potapova | Ian O'Malley - October 2013
Length Range: 22-45 µm
Width Range: 5.2-6.7 µm
Striae in 10 µm: 10-12

Description

Valves are linear with apices that are capitate in larger specimens to slightly protracted in smaller specimens. The axial area is lanceolate widening into a large central area reaching the valve margins. The raphe is almost straight, with proximal ends deflected to one side. Striae are often slightly bent, radiate near the valve center and become extremely convergent at the apices.

Note that some specimens from US have a higher stria density than specified in the original description. Most specimens in the study populations, however, had stria density that fit the original description of P. saprophila.
