Descriptor : Link between vertical intervallar structures

Descriptor type : categorical

Vertical intervallar structures: Longitudinal and often radial structures inside the intervallum (septa, taeniae...).

Intervallum: Space enclosed between the walls.

None

Synapticulae

Synapticula (plur. synapticulae): Narrow horizontal rod linking two adjacent vertical intervallar structures.

Plates

Plate: Porous plate linking adjacent radial-longitudinal partitions (septa, taeniae, etc).
NB: Resembles a flat synapticula.

Pillars

Pillar: Longitudinal rodlike structure connecting adjacent tabulae.

Tabula (plur. tabulae): Transverse porous partition linking both walls of a two-walled cup.
