Morphotype B

(Fig. 5A, B)

MATERIAL. — One specimen: IGR-23259 .

DESCRIPTION

The specimen consists of a strongly fragmented, simple and quite narrow leave (Fig. 5A, B). The apex and the base are not preserved. The specimen is 25 mm long and 15 mm wide. The lamina has entire margins. The primary venation is pinnate and straight. The secondary venation is eucamptodromous, merging into intramarginal veins (Fig. 5B). They are oppositely to alternately arranged, forming an angle of 35 to 50° angle with the primary vein. The tertiary venation is reticulate (Fig. 5B).

REMARKS

The specimen is preserved as impression. IGR-23259 differs from the Morphotype A by the absence of brochidodromous secondary venation and percurrent tertiary venation.
