Morphology

The vegetative morphology features a robust tree habit, with intricately veined leaves and frequently acuminate apices. As is common in the genus Celtis, the leaves may exhibit basal asymmetry, a distinctive feature for identification. The bark protects the wood against humid tropical climatic conditions.

The inflorescences develop inconspicuously among the foliage. Following fertilization, globose drupes form and gradually mature. These fruits house rigid, spherical seeds, ensuring the propagation of the species.

Interesting facts

First formally described in 1977 by the botanist Engkik Soepadmo, this species showcases the extensive reach of the Celtis genus across distinct geographical zones, from the Moluccas to New Britain.
