Osmunda Petioles & Roots
 |
| The C-shaped xylem strand can be clearly seen in this petiole cross-section. A sclerotic ring of fibers encloses the xylem. Smaller root structures can be seen interspersed between the petiole cross-sections. A very colorful and well- preserved Osmunda specimen is pictured below. Both specimens are Jurassic in age and were collected in Australia. |
