sider to be a second species. In the general habit of Lomagramma, 

 and in the articulation of the pinnae with the rhachis, it resembles 

 StenocJilcena ; from which, however, it is distinguished by a reticulated 

 venation, and in the fertile pinnae being destitute of an indusium, 

 bearing the sporangia " on the marginal portion" of their disk.
