Cladophlebis sp.

Fig. 3A.

1962 Cladophlebis arctica (Heer) Kryshtof. ; Cieśliński and Milaković 1962: 174, pl. 1: 1.

Material.—Fragment of a leaf PIG 60 III 1, Ignacówka near Pińczów, upper Campanian or lower Maastrichtian.

Description.—The single specimen is a fragment of a last or− der pinna about 45 mm in length with about thirteen variously preserved pinnules. The rachis is slightly wider than 1 mm. The pinnules are alternating, obliquely inserted, and densely spaced: each one covers a fragment of the adjacent basiscopic pinnule. The pinnules are elliptic in shape, integrimarginate, quite large and short (up to 10 mm long and 7–8 mm wide), asymmetric (the catadromous side is about one fourth wider than the acrodromous one). The main vein is straight, departing from the rachis at an angle of about 45–55 °; the angles between the main vein and the secondary veins are about 30 °. The secondary veins are sometimes forking dichotomously just after leaving the main vein.

Remarks.—A large part of representatives of the form genus Cladophlebis belong to the Osmundaceae and some of them to other families (e.g., Dicksoniaceae ). The available characters do not permit the assignment of Cladophlebis sp. described here to any family.
