General Description
 
Tree & Wood Descriptions for: Mansonia altissima
 

Product Sources

It is currently unknown whether material from this species is available from sustainably managed, recycled, salvaged, or other environmentally responsible sources.


The International Tropical Timber Organization (ITTO) reports that the species is a regular source of timber for export. Export of the material in the log form is prohibited in Ghana and Nigeria.


Mansonia is reported to be available in limited quantities in both the lumber and veneer forms. It is reported to be priced in the moderate range, but is more expensive than American black walnut.


Properties of the following species in the database are reported to be similar to those of Mansonia:


Piquia (Caryocar villosum )


Tree Data

The tree, which is usually buttressed, has a clear and straight bole with a diameter between 24 and 42 inches (60 and 100 cm), and a height from 100 to 120 feet (30 to 36 m).


Sapwood Color

The sapwood is usually white in color, and is sharply demarcated from the heartwood.


Heartwood Color

The heartwood varies from yellow-brown to dark gray-brown to light mauve in color, and is often purplish with lighter or darker bands. The purple color is reported to fade after prolonged exposure. Color variation is reported to be rather significant.


Grain

The grain is generally straight, but may be crossed. The heartwood is reported to be similar in appearance to American black walnut, but it has closer pores and a different grain structure.


Texture

Texture is medium and even.


Luster

The wood has a low to medium luster.


Odor

There is no distinct odor or taste.


Movement in Service

Seasoned wood is reported to have moderate dimenmsional stability, and shows medium movement in use.


Natural Durability

Mansonia is reported to be resistant to termites, but it is susceptible to pin hole borer and longhorn beetle attack.


Resistance to Impregnation


The heartwood is highly resistant to impregnation. The sapwood is permeable.


Weathering Properties

Mansonia is reported to have good weathering qualities, and is reported to be suitable for shingles.


Toxic Constituents

Fine dust produced from machining operations is reported to be extremely irritating, especially to respiratory passages. The bark of the wood also contains mansonin, a cardiac poison of the digitalis group. Use of face masks and barrier skin creams is recommended.
