Other Common Names: Canella imbuia, Embuia, Embuya (Brazil).
Distribution: Grows mostly in the moist Araucaria forests of Parana and Santa Catharina in southern Brazil, mostly at altitudes of 2,500 to 4,000 ft; forming rather rich stands.
The Tree: The tree attains a maximum height of 130 ft and a trunk diameter of about 6 ft.
General Characteristics: Heartwood yellowish or olive to chocolate brown, either plain or beautifully variegated and figured; sapwood is gray and usually distinct. Texture rather fine; grain is straight to curly and wavy; luster medium to rather high; spicy resinous scent and taste but losing most of it in drying. Dust arising in working may cause dermatitis.
Weight: Basic specific gravity (ovendry weight/green volume) 0.53; air-dry density 40 pcf.
Mechanical Properties: (First set of data based on 2-cm standard; second set on the 2-in. standard.)

Janka side hardness 880 lb for green material and 950 lb at 12% moisture content. Amsler toughness 182 in.-lb at 15% moisture content (2-cm specimen).
Drying and Shrinkage: The wood is reported to be easy to air-dry, however thick stock is slow to dry and may develop honeycomb and collapse. Kiln schedule T6-D2 is suggested for 4/4 stock and T3-D1 for 8/4. Shrinkage green to ovendry: radial 2.7%; tangential 6.0%; volumetric 9.0%.
Working Properties: Saws and machines satisfactorily and finishes smoothly. Fine dust generated in working may cause dermatitis.
Durability: Heartwood is reported to be resistant to attack by decay fungi.
Preservation: No information available.
Uses: Fine furniture and cabinet work, paneling, flooring, gunstocks, decorative veneer, and joinery.
