Radial section

  Simple perforation plates. Homogeneous to heterogeneous rays, often with up to three rows of square or upright marginal cells. Ray cells thick-walled. Large ray-vessel pits. Libriform fibres occasionally septate, vasicentric tracheids frequent.

Tangential section

  Rays generally 4- to 8-seriate, often narrower or wider. Wide rays with large intercellular spaces frequent. Ray height often higher than 5 mm.
