A ffinities.—Sphenopteris ovatifolia, sp. noy., differs from Renaultia 
Footnert (Marratt) in the pinnules being much larger, in the rachis 
not being winged, and in the shape of the pinnules. Renaultia 
cherophylloides (Brongn.) was at first thought to be the species to 
which these specimens belonged ; but it is really quite distinct. The
