Description Of The Tree

Botanical Description

The commercial lengths are reported to average 6 to 7 m, with diameters from 45 to 55 cm. The logs are reported to be straight and cylindrical, with low buttresses.

Natural Habitat

Hymenolobium modestum is a dominant tree found in the canopy of terra firme tropical rain forests of northern South America. It is reported to prefer dry areas.

Natural Distribution

The natural distribution range of this genus is the Amazon basin and northern South America.

Non Timber Uses

Fairly often oily or waxen patches can be observed.
