Found on well drained soils as well as periodically flooded river banks. Heartwood Color Brown Red Green/grey Pale brown Yellow to golden-yellow to orange White to cream Yellowish brown Pale red to pink Greenish to greyish Brown The color of the heartwood is described as light yellowish brown, sometimes with a slight pinkish- or purplish-blue overcast. Sapwood Color White to yellow Same as heartwood Cream Color not distinct from heartwood Grain Straight Figure Stripe (figure) Even Other (figure) Growth rings (figure) Irregular Straight Striped figure Other figure Irregular Clear growth rings (figure) The grain is straight to irregular. The timber often exhibits an attractive striped figure produced by narrow bands of darker-colored material. Texture Medium Fine Fine to medium Luster Lustrous Medium Dull Natural Durability Resistant to termites Susceptible to attack from termites (Isoptera) Pinworms (ambrosia beetles) are commonly present Non durable Sapwood is susceptible to wood staining fungal attack Moderately durable Heartwood is susceptible to wood staining fungal attack Vulnerable to attack by pinhole borers Vulnerable to attack by dry-wood termites Vulnerable to attack by decay fungi Susceptible to attack from powder post (Lyctid & Bostrychid) beetles Resistant to attack from powder post (Lyctid & Bostrychid) beetles Perishable Odor No specific smell or taste Kiln Schedules Dry at a slow speed Drying Defects Checking Collapse Distortion Slight twist/warp Slight surface checking No surface checking Slight spring/bow Slight end splitting Slight cupping No end splitting No cupping, generally Air-Drying is accompanied by very little warping and practically no surface checking Ease of Drying Slowly Thick Stock Requires Care Moderately Difficult to Difficult Difficult No info available on kiln drying Air dries slowly Tree Identification Bole/stem form is not buttressed Bole/stem form is misshapen Tree Size Trunk diameter is 100-150 cm Trunk diameter is 150-200 cm Trunk diameter is 200-250 cm Comments General finishing qualities are rated as good Genipa fruit is used for the production of a sour refreshing drink. An indelible stain is prepared from the immature fruit.
