Osmunda
Queensland, Australia
17 cm x 20 cm
This is an unusually large cobblestone specimen that has a mass of 4.3kg. This specimen also exhibits great color and preservation. You can even make out the stipular wings that outline the petiole cross-sections.
The two images below "zoom" in on a petiole cross-section next to a root structure.
A Dino-Lite AD7013 MT 5.0 MP is used to zoom in on the leaf petiole at 50x. The Image was resized in Adobe Photoshop CS6.
