Cymbellafalsa
Valves weakly asymmetric about the apical and/or transapical axis
Apical porefields present on both ends
Valves are symmetric to weakly asymmetric to one or both of the transapical and/or apical axis. The raphe is filiform and straight. Central raphe ends deflect to the primary side, while the distal ends deflect to the secondary side. Areolae are uniseriate. Both valve ends exhibit an apical porefield which may visible in LM.
