Common Name: Iroko

Scientific Name: Miliciaexcelsa, M. regia (syn. Chlorophoraexcelsa, C. regia)

Origin: Tropical parts of Africa

Tree Size: 100-130 ft (30-40 m) tall, 3-5 ft (1-1.5 m) trunk diameter

Average Dried Weight: 41 lbs/ft3 (660 kg/m3)


Color & Appearance:

Iroko heartwood is mostly yellow to gold or medium brown, with color usually darkening over time. The pale yellow sapwood is obviously delineated from heartwood.

Grain & Texture:

Iroko has a medium to coarse texture, open pores,with an interlocked grain.


This wood is diffuse-porous with big pores in no precise arrangement. It has solitary and radial multiples of 2-3; tylosesis common. Growth rings are indistinct; rays are visible without lens. Parenchyma is banded, paratracheal parenchyma is vasicentric, and the wood is aliform (winged, lozenge) and confluent.

Rot Resistance:

Iroko is very resilient and resistant to rot and insect attacks; it is sometimes substituted for true Teak.


Iroko is mostly easy to work, but its interlocked grain may cause some tearout during surfacing processes. In addition, deposits of calcium carbonate are at times present, which can have a substantial dulling effect on cutters. Iroko finishes and glues nicely.


Iroko has no characteristic odor.

Alergies & Toxicity:

Even though severe reactions are very uncommon, Iroko has been reported to be a sensitizer. Most common reactions include eye, skin, and respiratory irritations. Iroko can cause additional health problems in sensitive persons, including asthma-like symptoms, boils, or hypersensitivity pneumonitis.

Pricing & Availability:

Iroko is imported at a moderate price. Veneer is often for sale and is inexpensively priced.


This species is not listed in the CITES Appendices; however, Iroko is on the IUCN Red List. It is listed as vulnerable becauseof population reduction over 20% in the previous three generations, which is caused by decline in the wood’s natural range and by exploitation.

Common Uses:

Iroko is used for flooring, cabinetry, veneer, furniture, boat building, turned objects, and smaller specialty wood items.


Because of the high price of genuine Teak, Iroko may be considered a lower-cost alternative. This wood is stable and durable, with an overall appearance that resembles Teak.
