Summary
| Description |
English: A transverse thin section of the Podocarpoxylon texense holotype wood. "Fig. 7.- Transverse section. Here the highly resinous nature of the wood is well brought out, for not only the rays but many of the tracheids are filled with opaque resin. This is particularly true of
the summer tracheids, a line of which passes horizontally across the middle of the field. In the radial walls of several of the tracheids large pits are seen in section, appearing as two delicate walls bounding a lenticular area whence the middle lamella has disappeared." Eocene, 55 - 43 mya; "lignite mine at Rockdale station, Texas" Repository not identified. |
