Suleyman Demir notes:
This sp. shows mostly 3-4 central spines of which the dominant one is porrect and the other 2-3 often directed upwards and somewhat thinner. There are also arrangements in cross-form, which has been named as C.gladiispina earlier.
Here, you will see this sp. in its cross-formed central spine patern (forma gladiispina).
