Description

Valves are linear-lanceolate to lanceolate, with some specimens slightly or even distinctly asymmetric to the transapical axis, although this is not characteristic of the species. The apices are set off slightly and rounded but not capitate. The axial area is very broad and the width can be variable within populations. No central area is evident. The length:breadth ratio is also variable, even in this more restricted sense of the species (as compared to the interpretation of Krammer and Lange-Bertalot 1991). Striae are costate, areolae are not visible in the LM. Both apices appear to have small pore fields.

Patrick (in Patrick and Reimer 1996, p. 141) gives a detailed review of the nomenclature of this species.
