Seeds winged, with an elliptical to subrounded seed body, strengthened at the base and somewhat pointed at the opposite end, with a single narrow elongate membranous wing. Seed body oriented slightly obliquely to the long axis of the wing. One of the lateral margins is straight, the other slightly convex, distal end of wing rounded.

D i s c u s s i o n: Several morphotypes connected with transitions can be recognized and assigned to this species: In the opinion of Kvaček and Wilde (2010) they represent mere stages of maturation. Specimens designated Cedrelospermum sp. type I sensu Kovács (1959, p. 140, fig. 7 – Lábatlan) and most of the material from Messel and Kučlín (Pl. 7, figs 8-9) represent fully mature seeds with a robust seed body, sometimes truncate or with a more acute base, ca. 9 mm long and 4–6 mm high. The wing is almost parallel-sided, slightly narrowed towards the end, 22 to 28 mm long. The dorsal side of the wing is straight, slightly thickened and indistinctly deflected behind the seed body; the ventral side is also straight. The specimens from Lábatlan designated as Cedrelospermum sp. type II sensu Kovács (1959, p. 140, fig. 8, MAFI BK 3526/L 107 and other not figured material BK 3487/L26, 24) are smaller than the previous morphotype I with the wing 16 mm long, the dorsal side straight or slightly bent, ventral side straight. Not all species of Cedrelospemum are assignable to C. kovacsiae and are treated in a separate heading below.
