Polarised light micrograph of a longitudinal section of the mature wood of Arucaria augustifolia, known as the candelabra tree or Brazilian, or Parana, pine, although it is not a true pine but belongs to the genus Arucaria. The tree is on the critically endangered list as a result of logging and consumption of its fruit and seeds. Its numbers have been reduced by 97% in the last 100 years. Tracheids and vessels with circular pits are seen running vertically and medullary rays are seen running horizontally. Magnification: x40 at 10cm wide. | |
