Seeds ovoid to ellipsoid, often with flat sides, 4.6–6.1 mm long, 2.6–4.1 mm wide, apex rounded with a deeply cut furrow of raphe, base abruptly narrowed into short conical micropyllar tubercle, dorsal side with elliptic chalaza and short furrows radiating from there dividing the margin into radial lobes, ventral side with a narrow keel running from the apical incision to the base bearing a narrow line of raphe, 3–4 cross furrows running from the keel dividing the surface into transversal lobes ( Holý 1975, pp. 80-81, pl. 17, figs 8-11).

D i s c u s s i o n: According to Holý (1975) the material corresponds to the records common in Upper Lusatia, particularly from Wiesa near Kamenz. Specimens from Turów are distinctly bigger. Kirchheimer (1938) indicated T. lanceolarium (ROXB.) PLANCH. as a comparable living species, distributed mostly in lowland evergreen forests of Thailand, Indonesia, Myanmar, Vietnam and India.

M a t e r i a l: Ca. 25 seeds and several fragments, G 3046, 4623, 8845, Gs 108, 109, 236.
