Dicotylophyllum sp. 1

1967 Myricophyllum glandulosum Velen. ; Malicki et al. 1967: 227–228,

pl. 7: 20.

Material.—A single fragmentary leaf, MZ VII/32/41, from Kosobudy.

Description.—Blade attachement marginal, laminar size microphyll, length to width ratio>3:1. Blade shape oblong, medially dissymmetric, basal width symmetric, base shape slightly convex, apex not preserved. Margin entire. Venation pinnate, primary vein slightly curved. Secondaries eucamptodromous, alternating, their angle of divergence ca. 20–30 °.

Remarks.— Dicotylophyllum sp. 1 is quite similar to the leaf described above as aff. Eucalyptolaurus sp. in its slight asymmetry and eucamptodromous secondaries. Differences include lower angle of secondaries (20–30 ° compared to 40–50 °) and lack of any structure that could be interpreted as an intramarginal vein. Dicotylophyllum sp. 2 is symmetric and has subopposite and denser secondaries. Nonetheless, given the poor preservation of all the three specimens, it is not excluded they represent a single biological species. Dicotylophyllum sp. 4 and D. sp. 5 are more transverse.
