Mersawa Durian
Scientific name: Anisoptera laevis
Overview
Mersawa Durian (Anisoptera laevis) is a large tropical hardwood native to the lowland rainforests of Southeast Asia. A member of the Dipterocarpaceae family, it occurs naturally throughout Peninsular Malaysia, southern Thailand, Sumatra, and Borneo, where it grows in humid lowland forests on well-drained soils. It is one of several species marketed under the commercial trade name Mersawa and has long been recognized as an important source of quality timber throughout the region.
The wood is valued for its combination of moderate strength, dependable durability, and excellent workability. While it is not as visually striking as some highly figured tropical hardwoods, Mersawa Durian has earned a solid reputation in the woodworking and construction industries because of its consistent texture, straight grain, and ability to machine and finish well. It is widely used for furniture, cabinetry, plywood, architectural millwork, and a variety of interior applications.
Freshly cut heartwood ranges from pale yellowish-brown to light brown before slowly deepening in color with age and exposure. The grain is typically straight but may occasionally be slightly interlocked, producing subtle figure on quartersawn lumber. Its balanced combination of strength, stability, and workability continues to make it an important commercial hardwood throughout Southeast Asia.
Within the Asian hardwood group, Mersawa Durian represents one of the commercially significant members of the Dipterocarp family that has supplied the regional timber industry for generations.

Identification Characteristics
Mersawa Durian is recognized by its pale yellowish-brown heartwood, generally straight grain, and uniform appearance. The sapwood is lighter in color and clearly distinguished from the heartwood. Freshly sawn lumber often displays creamy yellow to light brown tones that gradually mature into a richer golden-brown over time.
The wood has a medium texture with moderate natural luster, while the pores are evenly distributed and growth rings are generally indistinct. Although most boards exhibit straight grain, occasional interlocked grain can produce attractive ribbon figure on quartersawn surfaces.
Key identification traits include:
- Pale yellowish-brown heartwood
- Cream-colored sapwood
- Straight to slightly interlocked grain
- Medium texture
- Moderate natural luster
- Uniform appearance
- Good dimensional stability
- Subtle ribbon figure on quartersawn lumber
Working Properties
Mersawa Durian is considered a relatively easy hardwood to machine and performs well using conventional woodworking equipment. Its moderate density allows it to cut cleanly while providing good strength for both furniture and general construction applications.
The wood planes, drills, glues, and sands well, producing smooth finished surfaces. It also accepts stains and clear finishes evenly, making it suitable for both painted and natural wood projects.
- Machines easily
- Planes cleanly
- Turns well
- Sands smoothly
- Accepts glue readily
- Finishes well
- Good nail and screw holding
- Moderate dimensional stability
- Suitable for veneer production
Safety Note
Wood dust from Mersawa species may cause skin, eye, or respiratory irritation in sensitive individuals. Proper dust extraction and respiratory protection are recommended during machining and sanding operations.
Common Uses
Mersawa Durian common uses include:
- Furniture
- Cabinetry
- Interior millwork
- Architectural trim
- Doors
- Window frames
- Paneling
- Plywood
- Decorative veneer
- Interior flooring
- General construction
- Utility woodworking
Sustainability & Notes
Anisoptera laevis is native to Southeast Asia’s biologically rich Dipterocarp forests, which represent some of the world’s most diverse tropical ecosystems. These forests support countless plant and animal species while supplying many of Asia’s commercially important hardwoods.
Like many tropical timber species, Mersawa Durian has experienced pressure from commercial harvesting and habitat loss in portions of its natural range. Today, sustainable forest management, responsible harvesting practices, and internationally recognized certification programs play an increasingly important role in maintaining healthy forest ecosystems while supporting long-term timber production.
Whenever possible, woodworkers are encouraged to purchase responsibly sourced lumber from reputable suppliers committed to sustainable forestry practices.

Collector Notes
Mersawa Durian is an excellent representative of Southeast Asia’s commercially important hardwoods. While it lacks the dramatic coloration found in species such as Padauk or Rosewood, it provides collectors with an opportunity to document one of the region’s most significant commercial timber groups.
Well-prepared samples display clean grain, consistent texture, and subtle natural beauty while offering useful comparisons with related woods such as Mersawa Paya, Keruing, Balau, and the Meranti group. Its importance within the Dipterocarp family makes it a valuable addition to educational and regional wood collections.
