In the fertile pinnules the lobes are replaced by obovate 
sporangia or seed vessels, alternately pinnate as in the barren 
frond, and becoming smaller toward the end of the pinnule. 
The plant representing this genus has a general resemblance 
to Cyclopteris dissecta, Goepp. (Sphenopteridium)*, as well as to 
Eremopteris of Schimper; but both these forms are bifurcate in 
the rachis, have more numerous veins and a more flabellate 
pinnule — It differs from Sphenopteris in the broad flat pinnules 
and absence of a prominent nerve in the lobes. From 
Hymenophy Hites by the absence of alation on the rachis and its 
sub-divisions. 
The fruitage may be compared with Palaeopteris, expect that 
the pedicelled group of reproductive bodies of the fertile pinnules 
of that fern, are replaced by a single sporangia or pod-like bodv 
in this genus.

The species is represented by incomplete fronds. 
The rachis is smooth but has longitudinal shallow furrows. 
Attached to it are pinnae the rachis of which has a somewhat 
scabrous, undulate surface, and shows when decorticated a num- 
ber of vascular bundles. 
The pinnules are set on this rachis about half an inch apart on 
each side and at an angle of about 50° to 70° ; they are long-oval 
in form, a re about an inch and a half to two inches long and are 
about three-quarters of an inch broad, and are slightly arched 
forward in the outer half. They are deeply incised into about five 
long narrow lobes on each side and a terminal lobe; the side 
lobes are directed forward at the ends and are decurrent on the 
mid-rib ; the lobes are alternately pinnate, slightly arched for- 
ward, have nearly parallel sides, and are truncate-lacineate at th° 
ends, where there are from three to five mucronate points ; in the 
lateral pinnules the first two lobes on the upper side are frequently 
united for one-half their length. The pinnules are thick and
