Otonephelium

The geographic distribution of this genus is concentrated primarily in South-East Asia. In these regions, the plants occupy specific ecological niches that require high precipitation levels throughout the annual cycle to maintain healthy physiological processes.

Soil requirements for Otonephelium are quite strict, necessitating deep, well-drained, and nutrient-rich loamy soils. The presence of organic matter is essential for supporting the growth rate and structural integrity of the tree canopy.

Regarding climate, the plant exhibits a clear requirement for tropical temperatures ranging from 22 to 30 degrees Celsius. It is highly sensitive to frost and cannot tolerate the cold stress associated with temperate or subtropical zones.

In terms of economic value, Otonephelium is recognized for its high-quality timber. The wood is utilized for various construction purposes due to its density, durability, and resistance to environmental degradation in humid conditions.
