M a t e r i a l. A cone from GLA19 (photograph), and three five-needled fascicles of leaves attached to the brachyblast, two from GLAz (MGPT-PU141011, MGPTPU141012) and one from GLA20 (MGPT-PU141095). Pinus pollen grains are quite abundant.
R e m a r k s. Five-needled fascicles are typical of the subgenus Pinus subgen. Strobus . The short cone recovered in a natural cross-section with rather thick scales is more similar to fossil-species of subgen. Pinus , e.g., P. hampeana (UNGER) HEER. Pollen grains are common and well preserved. There are two main pollen morphotypes: Pinus haploxylontype and Pinus diploxylon-type. The latter appears to be much more frequent in the pollen assemblage than Pinus haploxylon-type.
