Transversal section |
|
|
| |
Diffuse- to semi-ring-porous. Pores widely spaced in dendritic, radially orientated multiples. Wide pores occasionally surrounded by smaller, thick-walled ground tissue-like pores and vascular tracheids. Growth ring boundaries generally distinct in wide growth rings, indistinct in narrow growth rings. Parenchyma apotracheal, relatively abundant, generally in uni- to multiseriate, more or less continuous tangential bands, often also in uniseriate terminal parenchyma bands. |

Radial section |
|
|
| |
Simple perforation plates. Spiral thickenings present. Rays mostly composed of square and upright cells, slightly heterogeneous. Ground tissue predominantly composed of libriform fibres and vascular tracheids. (Distinction often difficult). |
|

| |
Tangential section |
|
|
| |
Rays predominantly uniseriate, seldom biseriate. Average ray height up to 15 cells. Ray cells small round to quite large, axial-oval to rectangular. Ground tissue cells often fusiform. |
