HUBUBALLI
Scientific name: Loxopterygium sagotii
Family: Anacardiaceae
Standard name: Siangenhout, Hububalli
Other names: Koika, Onotillo, Ormata
Wood Appearance
The wood is brown to reddish-brown and attractively figured. It contains numerous narrow to rather
wide darker stripes and streaks. It is of medium luster and texture. The grain is straight, sometimes
interlocked or wavy. The bole is 15-20m is length with a diameter of 40-90cm.
Physical and Mechanical Properties
It is moderately hard and ranges from medium to very brittle. Movement is low. Air dry Hububalli
compares closely with Burma Teak in all strength properties except compression and tension
perpendicular to grain:
• Air dried density (12%) - 680kg/m 3
• Bending strength (at 12%) - 94 N/mm 2
• Modulus of elasticity (at 12%) - 12060 N/mm 2
• Crushing strength (at 12%) - 51 N/mm 2
Timber Processing
Drying - Easy
Working - Drying is slow and moderately difficult with moderate risk of distortion and checking.
Owing to the presence of highly interlocked grain, it is also difficult to machine.
Assembly - Nailing is good but gluing needs care.
Finishing - Good. There may however be difficulties varnishing due to the presence of gum.
Natural Durability
Moderately resistant to decay and termites and highly resistant to moisture.
Uses
Because of its attractive figuring and relative scarcity the wood is best suited for panelling, highgrade
furniture and cabinet work.
Supplies
The wood is frequently found in the far interior. Moderate quantities are available for export.
