Basionym : Platanus pseudoguillelmae Krasser, 1896 var. varienervis Drygant, 1998 .

Type (and only) material: Holotype, incomplete leaf L PB−K.34 (formerly 37934). Pidtemne, Maastrichtian.

Description.—Blade attachment marginal, laminar size notophyll (length ca. 10 cm), length to width ratio <1.3:1. Laminar shape probably elliptic with medial asymmetry and base asymmetry. Base shape convex, base angle acute; apex not preserved. Margin serrate (distally) with small closely spaced (each ca. 4 mm) teeth, possibly entire proximally.

Primary venation suprabasal actinodromous, primaries incurved. Secondaries probably craspedodromous, nearly straight, their attachement excurrent, angle increasing distally. Tertiaries not preserved.

Remarks.— Dicotylophyllum varienerve from all other taxa described herein under the generic name Dicotylophyllum in much larger size. Its relationship to platanoids is unconfirmed.
