Summary[edit]
| Description |
English: A radial thin section of the Sequoioxylon laramense holotype wood. "Fig. 30.- Transverse section. This figure is included in order that the wood parenchyma may be shown. Scattered through the dense zone, whose uncrushed condition is evidently dependent on the very great thickness of its tracheid-walls, one can see cells with larger lumen than the majority which surround them; these are wood- parenchyma cells . In the lower right-hand part of the photograph three of these may be seen to have resinous contents."
Cretaceous (Maastrichtian),69-68 mya, Laramie Formation, Plentywood, Montana Repository not identified. |
