The Tree
A small to medium-size tree, attaining a height usually between 15m and 27m and a diameter of 0.3m to 1.2m. It enjoys damp situations along streams, and reaches its best development when growing in moist loam upon which rain has washed down layers of humus from woods at higher elevations.

Drying
The timber dries fairly rapidly with little degrade.

Strength
It has no reputation for strength, being comparable to poplar in general strength properties, although a little harder and rather more resistant in shear.
