Nyssa disseminata (LUDWIG) KIRCHHEIMER

Pl. 11, Fig. 6

Secondarily flattened endocarps, ovate to elliptic 18 and 19 mm long, 9 and 11 mm wide, apex acute to obtuse, base asymmetric rounded to cuneate, orbicular dehiscence valve at the apex, 3 mm in diameter, upper surface longitudinally ribbed, 8 and 9 in number.

Elliptic endocarps preserved as impressions are assignable to Nyssa disseminata (LUDWIG) KIRCHHEIMER because the length is less than 20 mm and there is a broad dehiscence valve covering the majority of the stone’s width. This species is common in a few Pliocene sites in Italy ( Martinetto 1995, Forno et al. 2015), but is here recorded for the first time in Miocene sediments.
