M a t e r i a l s t u d i e d. Needle leaves PA 1159.1,

1159.2, 1348.

D e s c r i p t i o n. Needles in fascicles of three were recovered from several impressions. The longest incomplete needles attain well over 100 mm in length; the cross section is triangular, the largest diameter being ca. 1mm. The sheath is over 10 mm.

D i s c u s s i o n. Such needles occur associated with seed cones of Pinus engelhardtii MENZEL in the early Miocene of the Most Formation (“Břešťany Clay”) (see Kvaček et al. 2004). The fossil species from there was described by Unger (1850, 1852; as Pinites rigios – see Hably et al. 2001) and reported repeatedly from the early Miocene deposits of North Bohemia. The occurrence of pine foliage in ternate fascicles from the České středohoří Mts. is rare, namely found at Žichov ( Ettingshausen 1866: 41, pl. 13, fig. 11; as

Pinus taedaeformis (UNGER) ETTINGSH. , frequently assumed as a synonym of P. rigios – e.g. Mai 1999).
