| Adaxial and abaxial leaflet surfaces were observed using scanning electron microscopy. |
| Electron microscopy of negatively stained samples revealed prolate ellipsoids. |
| Could the observed bundling be an artifact of specimen preparation for electron microscopy? |
| Cppd crystals are smaller rods, squares, or rhomboids and are difficult to identify with light microscopy. |
| However, starch granules are not refractive under bright field microscopy and usually have an indented center. |
| All figured specimens were coated with ammonium chloride prior to macrophotography and with gold for scanning electron microscopy. |
