Tanimbuca
Scientific name: Buchenavia tetraphylla
Overview
Tanimbuca is a tropical hardwood native to the Caribbean, Central America, and northern South America, extending into portions of the Amazon Basin. Buchenavia tetraphylla belongs to the Combretaceae family and occurs in a variety of tropical forest environments.
The wood generally ranges from yellowish brown to medium or darker brown, sometimes displaying olive, golden, or reddish-brown tones. Sapwood is typically lighter and can contrast noticeably with mature heartwood. Grain is usually straight to interlocked, while texture ranges from medium to coarse.
Tanimbuca is valued regionally for its combination of strength, durability, and attractive appearance. The wood is suitable for furniture, cabinetry, flooring, interior and exterior joinery, construction, turning, and other general woodworking applications. Although considerably less familiar internationally than many major South American hardwoods, it represents another useful and distinctive timber of the tropical Americas.
Quick Facts
- Common Name: Tanimbuca
- Alternate Common Name(s): Granadillo, Yellow Sanders
- Scientific Name: Buchenavia tetraphylla
- Region: South American Hardwoods
- Tree Size: Approximately 65–100 ft (20–30 m) tall, with trunks potentially reaching 2–3 ft (0.6–0.9 m) in diameter
- Average Dried Weight: Approximately 50–55 lbs/ft³ (800–880 kg/m³), with natural variation
- Janka Hardness: Reliable standardized species-specific value not consistently documented
- Grain: Straight to interlocked
- Texture: Medium to coarse
Identification Characteristics
Tanimbuca generally produces yellowish-brown to medium-brown heartwood that can develop golden, olive-brown, reddish-brown, or darker brown tones with age and exposure.
Sapwood is typically pale cream to yellowish brown and is generally distinguishable from the darker heartwood. Grain may be straight but commonly becomes interlocked or irregular. Quarter-sawn surfaces can potentially display ribbon-like figure.
Key identification traits include:
- Yellowish-brown to medium-brown heartwood
- Occasional golden, olive, or reddish-brown tones
- Pale cream to yellowish-brown sapwood
- Noticeable heartwood and sapwood contrast
- Straight to interlocked grain
- Medium to coarse texture
- Moderate natural luster
Working Properties
Tanimbuca can generally be worked successfully with conventional woodworking machinery, although its density and interlocked grain can make machining more demanding than with lighter hardwoods.
Sharp tools are recommended, particularly during planing and routing. Interlocked grain may produce tear-out, so lighter cutting passes and careful attention to grain direction can improve surface quality. The wood sands and finishes well when properly prepared.
- Machines reasonably well with sharp tools
- Moderate cutting resistance
- Interlocked grain may cause tear-out
- Turns well
- Sands to a smooth surface
- Accepts clear finishes well
- Pre-drilling is recommended for screws and nails
Safety Note
Detailed species-specific information regarding reactions to Tanimbuca wood dust is limited. Dust generated from tropical hardwoods during sawing, routing, turning, and sanding may cause skin, eye, or respiratory irritation.
Appropriate dust collection, eye protection, and respiratory protection are recommended during woodworking operations.
Common Uses
Its strength, density, durability, attractive appearance, and useful working characteristics make Tanimbuca suitable for numerous woodworking applications, including:
- Furniture
- Cabinetry
- Flooring
- Interior joinery
- Exterior joinery
- Construction
- Architectural millwork
- Wood turning
- Decorative woodworking
- General carpentry
Sustainability & Notes
Tanimbuca has a broad tropical American distribution, although commercial availability varies considerably between regions. As with other tropical hardwoods, responsible forest management and traceable sourcing are important considerations when purchasing lumber.
Regional common names can also create identification problems. The name Granadillo, for example, is applied to several unrelated tropical hardwoods. Scientific identification is therefore particularly valuable when documenting Tanimbuca lumber or collector specimens.
Material from responsibly managed forests, documented salvage operations, or other traceable sources is preferable whenever available.

Collector Notes
Tanimbuca is an excellent collector species because it represents a lesser-known member of the Combretaceae family and another example of the extraordinary hardwood diversity of tropical South America.
Its yellowish to darker brown coloration and potentially interlocked grain provide useful comparison points with other South American timbers such as Sucupira Preta, Angelim Pedra, and Copaiba Balsam.
Because several of its regional trade names can also refer to unrelated species, collector specimens should retain the scientific name Buchenavia tetraphylla, geographic origin, supplier information, and acquisition date whenever available.
