Morphology

The leaf dimensions and growth form help distinguish this species from its close relatives. Key morphological features include:

  • Leaf Size: The leaves are lanceolate to oblong-elliptic, often reaching lengths of up to 25 centimeters, with long-acuminate tips.
  • Leaf Margins: Serrated margins are typical, particularly on young leaves and new growth.
  • Fruiting Bodies: The drupes are ovoid, fleshy, and turn yellowish-orange when mature, containing a single stony seed.

Applications

Like other large forest trees in the region, the wood is occasionally utilized for light construction work. It is an essential component of forest restoration projects due to its ability to grow in disturbed soil. The leaves and fruits are utilized by native wildlife for food and nesting materials.

Interesting facts

Its name longifolia literally means "long leaves," highlighting its most prominent visual feature. The tree grows relatively fast when gaps open in the forest canopy, capturing light efficiently. The fleshy drupes are highly sought after by local bird species, ensuring wide seed distribution.
