Abura (Mitragyna ciliata)

Common Name(s): Abura, bahia

Scientific Name: Mitragyna ciliata (previously listed in Fleroya genus; see comments below)

Distribution: Mountainous regions of Europe

Tree Size: 100-115 ft (30-35 m) tall,
                 3-5 ft (1-1.5 m) trunk diameter

Average Dried Weight: 35 lbs/ft3 (560 kg/m3)

Specific Gravity (Basic, 12% MC): .45, .56

Janka Hardness: 820 lbf (3,670 N)

Modulus of Rupture: 11,760 lbf/in2 (81.1 MPa)

Elastic Modulus: 1,386,000 lbf/in2 (9.56 GPa)

Crushing Strength: 6,220 lbf/in2 (42.9 MPa)

Shrinkage: Radial: 4.3%, Tangential: 9.2%,

                  Volumetric: 13.3%, T/R Ratio: 2.1

Color/Appearance: Has a uniform yellow to pinkish-brown color, with sapwood indistinct from heartwood.

Grain/Texture: Fine texture and a straight or slightly interlocked grain.

Rot Resistance: Non-durable; poor resistance to decay or insect attack. Good acid resistance.

Workability: Takes glue and finishes well. Has a slight blunting effect on cutting edges and tools due to a moderate silica content (.25%).

Odor: Has an unpleasant odor when freshly cut.

Allergies/Toxicity: Has been known to cause allergic reactions including: nausea, eye irritation, giddiness, and vomiting. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Seldom available in North America. Price should be moderate when compared to other imported lumber.

Sustainability: This wood species is not listed in the CITES Appendices, but is on the IUCN Red List. It is listed as vulnerable (both Mitragyna ledermannii and M. stipulosa) due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.

Common Uses: A general-purpose lumber used for furniture, interior millwork, plywood, and flooring.

Comments: Sometimes sold under the commercial name bahia, the handful of African species from the Mitragyna genus that are sold interchangeably with one another include: M. ciliata, M. ledermannii, and M. stipulosa. These species have been formerly placed in the Hallea genus (now considered a synonym), and Fleroya (in 2007), but have since been returned to Mitragyna (see 2014 article).
