78 RUFFORDIA. 
Sphenopteridis. Fructification in the form of scattered sporangia 
on fertile fronds or pinne, of which the leaf lamina is considerably 
reduced. 
Sphenopteris Phillipsti, Mant., may probably be included in the 
list of synonyms, although the fragment figured under this name 
is so small that its real nature must remain uncertain. It agrees 
very closely with some of the more broadly lobed forms of the 
present species. 
There is no doubt as to the specific identity of S. Hartlebeni, 
Dunk., and S. longifolia, Dunk., with the present species, as 
Schenk -has already pointed out. 
Jeanpaulia nervosa, Dunk.,! is included by Heer? as a synonym 
of S. valdensis, Hr., but a comparison of the figures lends little 
or no support to Heer’s view. Dunker’s J. Brauniana is much 
more like some of the English specimens of Ruffordia Gépperti 
than any other forms of that genus. 
On comparing Ettingshausen’s figure of Sphenopteris Jugleri 
with those of S. Gépperti given by Dunker and Schenk, certain 
differences are at once apparent, but the inclusion by the latter 
author of Ettingshausen’s species in that of Dunker is fully 
confirmed by the specimens in the Museum Collection. The 
specimen from the ‘‘ Lower Shale” (Yorkshire Oolite) referred 
by Leckenby to S. Jugleri shows a very distinct resemblance to the 
Wealden fern, and may possibly be rightly included in that species. 
An examination of the type specimen in the Woodwardian 
Museum, Cambridge, suggests a strong likeness to Pl. V. Figs. 2 
and 8 of Ruffordia Gopperti (Dunk.); considering the small size 
and imperfect nature of Leckenby’s specimen, it is better to avoid 
an unqualified assent to its association with the present species. 
Schimper includes a species, Sphenopteris (Zrichom.) Gépperti, 
Ettingsh.,*> under the heading Sphenopteris-Trichomanides, but 
this was instituted by Ettingshausen, in 1865, under the name 
Trichomanites Gopperti* for the reception of a plant from the 
Dachschiefer of Moravia and Silesia. Sphenopteris Gopperti, Dunk., 
is included by Schimper as a synonym of S. Hartlebeni.
