This plant has only once been previously recorded from Britain. 

 from the Middle Coal Measures of Yorkshire. The leaf is rather 

 small and narrow in this species, the nerves being fine, equal in 

 strength, and close. The specimen figured in PI. XIII, fig. is 

 probably the basal portion of a leaf of this species.

Gordaicladus is an excessively rare genus in Britain, and this 

 is only the second record of the speeies from British rocks. The 

 leaf-scars in this species are mounted on cushions, which are closely 

 approximated.
