Grain/Texture: No data available.
Endgrain: Diffuse-porous; very large pores in no specific arrangement, very few to few; solitary and radial multiples of 2-3; tyloses occasionally present; growth rings distinct due to increased pore frequency in earlywood zone; narrow to medium rays may be just visible without lens, spacing normal; parenchyma vasicentric and winged.
Rot Resistance: No data available.
Workability: Wood may stain when in contact with iron.
Odor: No characteristic odor.
Allergies/Toxicity: Although severe reactions are quite uncommon, Idigbo has been reported to cause skin and respiratory irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.
Common Uses: No data available.
Comments: Idigbo contains a water-soluble yellow dye that can leach out when the wood becomes wet.
