It grows in the rain and savannah forests, and is a good plantation species in West Africa. Heartwood Color Yellow Brown Green/grey Orange White Red Yellow to golden-yellow to orange Pale brown Greenish to greyish White to cream Brown Grey brown Limba sometimes has black, irregular streaks which give the wood an attractive appearance Sapwood Color White Yellow Brown Red Same as heartwood Not clearly differentiated from the heartwood Grain Straight Interlocked Figure Distinct (figure) Closed Even Growth rings (figure) Irregular Straight Interlocked Distinct figure Distinct and very fine figure Straight to interlocked May be straight, irregular, or wavy Clear growth rings (figure) Texture Coarse Medium Coarse Medium Moderately coarse Medium coarse to coarse Fine Luster Medium High Lustrous Pronounced High Dull Wood surface has a high, satiny luster. Natural Growth Defects Brittleheart is often frequent and extensive Natural Durability Non-durable Perishable Susceptible to insect attack Resistant to marine borers Non-resistant to powder post beetles Non-resistant to termites Moderately durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Pinworms (ambrosia beetles) often present in the standing tree Susceptible to attack from termites (Isoptera) Non durable Sapwood is susceptible to wood staining fungal attack Perishable Pinworms (ambrosia beetles) are commonly present Susceptible to marine borer attack Pinworms (ambrosia beetles) may be present in the felled log Heartwood has very low resistance to decay It is readily attacked by termites, ambrosia beetles, and powder-post beetles. Felled trees require special preventive care to protect the heartwood against deterioration. Odor No specific taste Mild odor Light-Induced Color Change Darker Toxicity Unspecified toxicity Dermatitic effects Respiratory effects Wood splinters are reported to cause inflammation of the skin in some individuals. Kiln Schedules Drying (speed) is fast UK=J US=T10D5S/T8D4S Fr=4 Kiln Drying Rate (in days) is rapid T10 - D5s (4/4); T8 - D4s (8/4) US Schedule J (4/4) United Kingdom Dry at a slow speed Drying Defects Splitting Distortion Checking Discoloration Slight twist/warp Slight surface checking Slight end splitting No surface checking Severe end splitting No twisting or warping No end splitting Shakes and splits are common during air-seasoning. Kiln-drying is often accompanied by minimal checking and warping. Ease of Drying Fairly Easy Reconditioning Treatement Easy Dries rapidly and well with little degrade under controlled conditions Kiln Drying Rate Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm) Tree Identification Bole/stem form is buttressed Bole/stem form is straight Bole/stem form is cylindrical Tree Size Tree height is 40-50 m Bole length is 30-40 m Trunk diameter is 150-200 cm Trunk diameter is 100-150 cm Bole length is 20-30 m Bole length is 10-20 m Tree height is 30-40 m Bark width is 20-25 mm Bark width is 25-30 mm Tree height is 20-30 m Trunk diameter is 200-250 cm Trunk diameter is 250-300 cm Product Sources Supplies are plentiful and the material is available in the form of veneers and lumber. Price is in the moderate range. Substitutes Ako (Antiaris africana and A. welwitschii), African pterygota (Pterygota bequaert and P. macrocarpa) and Brown terminalia (Terminalia brassii) are substitutes for some end uses.
