The single pinnule shown in the woodcut agrees very closely with one figured by Potonio' in a Carboniferous fern, Sphenopteris Hoeninghausi, Brong., var.

Probably a pinna from the basal portion of a frond. Pinnules ovato-lanceolate and lobed. The venation is fairly distinct, but, as is usually the case with carbonaceous impressions on clay, not nearly. Fig. 11 (V. 2162). Enlarged 3 times. so well marked as on the ironstone. The figure shows a median, and less marked lateral veins. Some of the pinnules in Fitton's type specimen correspond fairly closely with those represented in 1 Jahrb. k. preuss. Geol. Landesanst, 1890, p. 23, pi.
