Transversal section |
|
|
| |
Diffuse- to almost semi-ring-porous wood. Pores rather small, infrequent, solitary or in small clusters. Pores often in more or less tangentially orientated or oblique bands or groups. Growth ring boundaries generally indistinct, with 1 to 3 rows of radially flattened, thicker-walled latewood cells. Rather thick-walled ground tissue. Sparse apotracheal parenchyma cells. |
     
|
| |
| |
Radial section |
|
|
| |
Scalariform perforation plates with 8 to 14 bars. Uniseriate rays with square and upright cells, multiseriate rays heterogeneous with one to some rows of square and upright cells. Libriform fibres frequent, fibre-tracheids rare. |
  
|
| |
| |
Tangential section |
|
|
| |
Numerous low, uniseriate, heterogeneous rays and multiseriate, 4 to 15 cells wide rays, spindle-shapened, often over 2mm high. In these wide rays sheath cells present. |
