Description Of The Tree

Botanical Description

This tree is reported to be of small to medium size, attaining heights of 25 m and diameters of 60 to 80 cm. The boles are straight and cylindrical, clear to heights of two thirds of the total tree height. It presents buttresses 1 m tall.

Natural Habitat

Tabebuia serratifolia is described as ecologically diverse, growing under a variety of conditions. It is found in primary and secondary forests on well drained soils, hills and close to rivers and streams in non-inundable areas. In Peru it is reported gro

Natural Distribution

From Mexico In Brazil it is reported until Sao Paulo in the south.

Non Timber Uses

The sawdust of T. serratifolia contains "lapachol", it is reported to cause skin irritation in some individuals.

Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 100 to 150 micras (small). Colored deposits in heartwood vessels. Vessels per mm2 10 to 20 (abundant). Simple perforation plates. Vessel-ray pits small. Int Axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma aliform. Axial parenchyma storied. Two cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays storied. Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.

Cites Status


General Wood Description


Odor or taste is typically indistinct.


The sapwood is yellow, clearly differentiated from the heartwood. The heartwood is olive-brown to dark olive in color.

COLOR INDEX (1=Black, 7=Light yellow,white)



The grain is straight to interlocked.


Texture is fine to medium. The wood is reported to have an oily look.


Wood surfaces have a moderate luster.

Natural Durability

It is highly resistant against fungi and insect attack, but susceptible to marine borer attack.

Natural durability index (1= Very high durability, 7=Vey low durability)


Resistance To Impregnation

The wood is reported to be highly impermeable to wood preservatives.

Total shrinkage Radial (Saturated to 0%MC) (%)


Drying Defects

Ease of Drying: It is reported to be moderately difficult to air season. Drying Defects: Slight surface checking and moderate to severe warp are reported. Some casehardening is also reported. Kiln Schedules: Careful drying is required, drying of quarter sawn pieces is advised.

Recommended Dry Kiln Schedule

Rotary Veneer Cutting

Logs are generally difficult to convert into veneers, they are reported to yield very decorative veneers.

Sliced Veneer

Logs are generally difficult to convert into veneers, they are reported to yield very decorative veneers.

Blunting Effect

Blunting effect on cutting edges is reported to be moderate.


The material is reported to work with some difficulty, but can be finished smoothly, except heavily interlocked material. Properties in turning, boring, and sanding are rated as good.


The material is reported to be fairly difficult to plane and work in most operations work. A reduced cutting angle of 15 degrees is recommended for best planing results.




Boring operations are rather easy.


The wood is hard and requires pre-boring for nailing.


Surface preparation is usually required for best gluing results.


The wood is reported to respond well to sanding operations.


It has a good finishing.


The wood is difficult to paint, powdery deposits of lapachol may affect varnishing. Surface preparation to remove yellowish lapachol powder may improve painting qualities.

Response To Hand Tools

The material responds poorly to hand tools.
