The fruit body is traversed by a straight median longitudinal vein and four additional longitudinal veins symmetrically placed on either side of the median vein.
Examination of the both counterpart impressions of the same fossil fruit show five veins on one side, but only a single median vein on the opposite side (Fig.

Black costal spines well developed, longer than height sc; membrane regularly pale brown infuscate, with 3 iridescent whitish patches over crossvein areas; veins distinctly brown; apex of each longitudinal vein with distinct brown infuscate area; Rj with large brown egg-shaped macula in apical section; r-m and dm-cu crossveins dark brown, with adjacent extensive infuscation; median vein
3]-treated seedlings, such that the first signs of median vein
formation in the initial designing of the leaf (Figure 3-1 E0) could be detected in the 100 mg/l [GA.
The vein of Galen (formed from the median vein
of the prosencephalon) is formed by the union of the two internal cerebral veins and goes on to drain into the straight sinus.
Median veins free, equidistant; inner sheath (IS) single- or
Median veins buttressed to abaxial and adaxial sides.
Median veins are an intermediate type between major and minor veins.
