1961 Acer sp. ; Knobloch, p. 286, pl. 7, fig. 8, pl. 11, fig. 8.

Isolated mericarps of winged double samaras, 22–45 mm long, 8–35 mm wide, seed part rounded, 5–7 mm in diameter, attachment scar at a very narrow angle to the fruit length.

D i s c u s s i o n. Knobloch (1961) proposed that the fruits occurring at Knížecí belong to foliage of A. palaeosaccharinum which prevails in the Knížecí plant assemblage. Such fruits have been described as Acer cyclospermum GÖPPERT from the upper Oligocene deposits in the Rhineland ( Winterscheid and Kvaček 2014). The connection between fossil maple fruits and foliage has not so far been firmly resolved.
