Izabal Wood Co.


Bullywood / Bucida buceras

Local Names
Bullet Tree, Black Olive, Cacho de Toro, Ucar, Gregre, Bois Gri-Gri, Grignon, Leertouwarsboom.
Distribution & Tree
Referred to alternately as black olive, oxhorn and bullet tree in English, pucté’s natural range comprises Mesoamerica through Panama into Colombia and Venezuela as well as various Caribbean islands including the Florida Keys, Bahamas, Cuba, Jamaica, Hispaniola, Puerto Rico, the Virgin Islands, and parts of the Lesser Antilles. It is salt tolerant and grows well in coastal swamps but also in drier limestone soils, developing an extensive root system that anchors the soil. It’s a medium to large tree reaching up to 20 meters high (sometimes higher) and diameters exceeding 100 cm.
Wood Appearance
Pucté’s heartwood ranges from yellowish to greenish-brown with an olive hue oftentimes with longitudinal stripes as a result of interwoven grain. It has a medium to fine texture and is very lustrous, almost glasslike. Fresh cut wood has a tarry odor that disappears after drying. The wood may have an attractive figure on its side surfaces.
Processing Properties
The wood is rather difficult to saw and machine with hand and power tools because of its very high density. Pucté yields very smooth finishes, but its grain may tear in planing. Pre-boring is recommended to avoid splitting.
Strength & Durability

Due to its high density and silica content, the wood is resistant to dry-wood termites and durable in ground contact. The Wood is designated as very resistant to decay (class 1 under ASTM D 2017-71 and EN 350-1). Susceptible to teredo marine borers. Its strength is said to resemble that of greenheart (Ocotea rodiaei).

Wood Uses
Exterior use in posts, poles, railway crossties, and other durable construction. Both heavy-duty and residential flooring. It can be used for furniture (e.g. tabletops), interior trim, tool handles, and decking. The wood is employed for marine construction, including ship keels and bridges, where borers not present.
Ecological & Social Importance
In Haiti, a bark and leaf decoction is taken for fever. The bark is high in tannin and has been used for tanning.
