OF COAL-MEASURE PLANT-IMPRESSIONS. 187 
Remarks.—The sporophylls of this rare type are very incompletely known. 
From Brongniart’s figure it would appear that, as in £L. Jacksoni, the laminas 
are distally contracted into narrow spines. The characters of the pedicel 
and the proximal portions of the lamina, which appear to differ from those 
of L. Jacksoni, are, however, obscure or unknown, and until these can be 
studied the specific value of this fossil must remain doubtful.
