Dicotylophyllum sp. 5

Material.—A subcomplete leaf JS 8 from Krasnobród, a fragmentary leaf from Chełmowa Góra KrS 2, a fragment L PB−K.18 (formerly 153) from Potelych.

Description.—Blade attachment marginal, laminar size notophyll (the blade is 7 cm long and 5 cm wide), blade medially slightly asymmetric, basally symmetric. Base shape convex, angle obtuse. Margin probably entire. Venation pinnate, secondaries straight for about half of the blade width, then poorly preserved, eucamptodromous?; their attachment excurrent, angle constant, about 50 °, spacing regular. Tertiaries not preserved.

Remarks.— Dicotylophyllum sp. 5 differs from other taxa described herein under the generic name Dicotylophyllum in smaller length to width ratio (and from Dicotylophyllum sp. 4 moreover in distinct secondary venation). Once again, it is not excluded that this morphotype does not represent a separate biologic species.

The fragmentary leaf of “ Magnolia polysperma Karczmarz, 1966 ” (MZ VII/37/31, Karczmarz and Popiel 1966: fig. 3; refigured by Kohlman−Adamska 1975: pl. 1: 1) might represent either Dicotylophyllum sp. 4 or Dicotylophyllum sp. 5 . For the status of this name and of Fagus cf. prisca sensu Cieśliński and Milaković (1962) see below, under Unidentified taxa.
