Summary
[edit]DescriptionTelephragmoxylon brachyphylloides holotype transverse section Torrey 1923 Plate14 fig52.png |
English: A transverse thin section of the Telephragmoxylon brachyphylloides holotype. "Fig. 52. Transverse section; detail of septate tracheids. In this highly magnified view the remarkable phenomenon which sets the genus apart is seen. Stretching obliquely across the field is a darker band of tracheids. The dark color is due to the fact that a lucky section has cut at least five tracheids in succession at such a point that their cross-walls are visible . On one of these septa a pair of bordered pits is clearly seen, and evidences of the same are visible on three more."
Cretaceous (Comanchean), 127-99.6 +/- 0.9 mya, Trinity Group, near Weatherford, Texas Repository not identified. |
