? 
Diagnosis.—Cone small, ovate. Sporophylls small, hastate, up to 2:5 cm. 
long and © mm. across at their greatest width. Pedicel wedge-shaped, 
narrow, about 1 em. in length. Lamina about 1-1:5 em. long and 5-7 mm. 
across at the base, all angles, especially the lateral, acute. 
Remarks.—'The present is the first British record of the species, and the 
only specimens so far known are detached sporophylls. Lesquereux has, 
however, figured a cone of this species. An excellent specimen from the 
Transition Coal Measures of Kent is seen on Pl. 8. fig. 9, natural size. 
Another example from the Upper Coal Measures of the Somerset Coalfield 
is seen slightly enlarged on PI. 8. fig. 10.
