The only Bucklandia species found in India, B. populnea occurs in the eastern Himalayas, Assam, Khasi and Naga hills at an elevation of 3280 to 8200 feet (1000 to 2500 m). Heartwood Color Purple Brown Green/grey Red Reddish brown White to cream Pale brown Greyish brown Greenish to greyish Brown Sapwood Color Brown Green/Grey Red Color not distinct from heartwood Blends into heartwood Grain Interlocked Figure Stripe (figure) Interlocked Striped figure Broadly interlocked Texture Fine Medium Fine Fine and even Luster Medium Slightly lustrous Dull to lustrous Natural Durability Non-durable Moderately durable Susceptible to insect attack Very durable Durable Resistant to attack from powder post (Lyctid & Bostrychid) beetles Pinworms (ambrosia beetles) are commonly present Perishable Moderately durable The heartwood is perishable in some areas (Malaya) and fairly durable in others (India).

Strength Properties Max. crushing strength = medium Bending strength (MOR) = medium Hardness (side grain) = soft Modulus of Elasticity (stiffness) = low Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = medium Density (dry weight) = 38-45 lbs/cu. ft. Toughness-Hammer drop (impact strength) = medium Toughness-Hammer drop (Impact Strength) = low Max. crushing strength = high Toughness-Hammer drop (Impact Strength) = very low Shrinkage, Tangential = large Shrinkage, Tangential = fairly large Shrinkage, Radial = small Shearing strength (parallel to grain) = medium Resists denting and marring Modulus of Elasticity (stiffness) = very low Heavy Hardness = medium Hardness (side grain) = medium Density = medium Density (dry weight) = 31-37 lbs/cu. ft.
