This species has also been listed in CITES Appendix II for material from West Africa. The appendix includes species that 'May Become Threatened' if their trade is not controlled. An in-country issued export permit is required to verify that the source of material is legal, and its removal will doe not threaten the survival of the species (Source - Convention on International Trade in Endangered Species of Wild Fauna and Flora - CITES - March, 1993) Distribution Overview Afrormorsia occurs in the semi-deciduous forests in West and Central Africa, and is found mostly in the Ivory Coast, Ghana, Cameroon, and Congo. Heartwood Color Brown Yellow Orange Green/grey White Black Red Yellow to golden-yellow to orange Brown Greenish to greyish Dark brown Reddish brown Purple The heartwood is initially orange-brown or brown in color, but turns into brownish-yellow, with darker streaks upon exposure. It has also been described as warm crimson-brown, lightened by bands of a bright golden-brown shade. The annual rings are usually distinct because of darker bands of dry-season material. The timber is reported to resemble fine-grained Teak (Tectona grandis) in appearance, but without the oily texture. Tannin in the wood can cause blue stains Sapwood Color White Yellow Paler than heartwood White to yellow Well defined Same as heartwood Light brown Clearly differentiated from the heartwood Grain Straight Interlocked Figure Even Distinct (figure) Stripe (figure) Rippled (figure) Mottled (figure) Straight Interlocked Striped figure Rippled figure Distinct figure Slightly interlocked Mottled figure Generally straight, but not always Wood surfaces are reported to exhibit a rippling sheen because of pores that are scattered evenly in small groups throughout the wood. Quartered surfaces exhibit a mottled figure Texture Fine Medium Fine Fine to medium Medium Luster Medium High Pronounced Medium Natural Durability Durable Perishable Moderately durable Susceptible to insect attack Non-durable Non-resistant to powder post beetles Non-resistant to termites Resistant to termites Very durable Resistant to attack from termites (Isoptera) Resistant to attack from marine borers Resistant to attack from powder post (Lyctid & Bostrychid) beetles Pinworms (ambrosia beetles) are commonly present Durable Susceptible to attack from powder post (Lyctid & Bostrychid) beetles The heartwood is rated as very durable and could last for more than 25 years in contact with the ground. The timber is rarely attacked by marine borers and is highly resistant to attack by termites in West Africa. Afrormosia should not be used in contact with iron and iron compounds under moist conditions, since corrosion will promote discoloration in the wood Odor Has an odor No specific smell or taste Light-Induced Color Change None Darker Toxicity Some toxic effects Unspecified toxicity Respiratory effects Dermatitic effects Poisonous Sawdust from machining operations is reported to cause eye irritation in some individuals. Good ventilation around working areas is recommended Kiln Schedules Dry at a slow speed UK=J US=T10D5S/T8D4S Fr=4 UK=H US=T10D4S/T8D3S Fr=7 UK=F US=T6D4/T3D3 Fr=6 Kiln Drying Rate (in days) is rather slow Drying Defects Distortion Checking Collapse Internal Honeycombing Possible Slight twist/warp The timber may distort slightly upon drying Ease of Drying Fairly Easy Moderately Difficult to Difficult Slowly Thick Stock Requires Care Easy Kiln-Drying is satisfactorily under moderate schedules Dries slowly with little degrade The wood ranges from fairly difficult to fairly easy to dry Kiln Drying Rate Naturally dries slowly Drying rate is fairly rapid to fast Slow (18-28 days for boards < 32 mm, to 52-84 days for boards >= 63 mm) Tree Identification Bole/stem form is buttressed Bole/stem form is straight Bole/stem form is fluted Bole/stem form is misshapen Bole/stem form is cylindrical Tree Size Trunk diameter is 200-250 cm Bole length is 10-20 m Tree height is 20-30 m Trunk diameter is 100-150 cm The unbuttressed trees attain heights of 160 feet (49 m). Boles are usually straight and are clear for about 100 feet (30 m). Trunk diameters are reported to to be 48 to 60 inches (120 to 150 cm). Product Sources The ITTO reports that timber from this species is produced regularly but in limited quantities. Export of the material is regular. Adequate quantities of Afrormosia in the form of logs, flitches, and lumber are available at prices that are lower than teak and other comparable exotic hardwoods. Substitutes Timbauba (Enterolobium schomburgkii) and Oiticica amarela (Clarisia racemosa) Comments General finishing qualities are rated as good Blunting Effect Moderate Little Blunting effect on machining is moderate Blunting effect on sawing dry wood is moderate Medium blunting effect on cutting tools Blunting is much less pronounced than in Teak.
