Amendoim Wood (Pterogyne nitens): Uses, Properties, Pros, and Cons

In northeastern Brazil, Amendoim Wood is a fast-growing species that is not very well known. Pterogyne Nitens is a plant that grows in subtropical and tropical areas, between about 80 meters and 1,400 meters above sea level.

It grows in the Caatinga biome, which is hard for trees to grow in because the soil is not very fertile and there isn’t much water.

Best when grown in a sunny spot. Does well in many kinds of soil. Young plants usually get off to a good start and grow quickly, reaching a height of 4 meters in just two years.

Amendoim wood is known for its unique grain, which seems to move in different directions depending on how the light hits it.

Over time, Amendoim wood will get a little darker. It is a very hard wood that works well in any room. It has small knots, so it is also used to make furniture and interiors that look from the past. A great wood that lasts a very long time.

Amendoim wood comes from deciduous trees with a round, open crown that can grow up to 30 meters tall. Most of the time, the bole is between 40 and 60 cm in diameter, but sometimes it can be up to 120 cm.

Amendoim is sold under other names

Different names know Amendoim wood in different places, but when it’s sold, it’s just called “Amendoim.” In Brazil, it is called Amendoim; in Paraguay, Ybyraro, and Bolivia, Ajunao.

Amendoim is also called “Brazilian Oak” in the United States, which can be confusing. The way they look is different.

Other Names: Pterogyne Nitens, Guiaro, Ajunao, Ibiraro, Viraro, Pau Fava.


Amendoim has a smooth, wavy grain in natural colors that range from light blonde to beige and rose Carmel.

Pin and cat’s-paw knots give this light, rustic, and better wood a unique look. This wood is hard and stable and is an excellent choice for anyone looking for natural wood with a lighter color to add to their home.


In the U.S., it’s almost impossible to find Amendoim lumber, so flooring lengths are limited to those of pre-milled products.


Amendoim is sometimes sold as lumber, but most of the time, it is sold as flooring planks. Prices for South American species brought in from other places should be in the middle.

Also, raw lumber is pretty pricey because it is taxed more than finished products in South America to help support local economies.


In northeastern Brazil, the species of Amendoim wood is called Amendoim-bravo or Madeira nova. It is thought to grow quickly in the Caatinga.

Amendoim is found throughout South America, including parts of Argentina, Paraguay, and Brazil.


Amendoim wood flooring adds a special touch of elegance to any room because it has a light color that isn’t common in most exotic woods.

Amendoim can get a deeper red color over time because its finish is made of oil.

Lacquer can be used first to help keep the wood’s unique red color and to speed up the drying process.

Water-based finishes will keep the natural color for longer.


The species is threatened by several things: its habitat is not protected and is shrinking because of logging and the spread of agriculture and pastoralism; it is sought after as a source of wood; and in Bolivia, it is one of several species that live in the semi-deciduous forest in eastern Santa Cruz that are being logged more.

Is Amendoim hard or softwood?

Wood type: hardwood.

Amendoim is also one of the world’s hardest types of wood. When you add an aluminum oxide finish that protects the surface from wear and makes it scratch-resistant, you have one of the best exotic hardwoods that are easy to care for.

Amendoim is more stable than most hardwoods and doesn’t rot if it isn’t treated with chemicals. It is also very strong when bent, which makes it a good choice for places where the boards will be put under much stress.

Amendoim is hard is another reason why people choose it for their floors.

The Janka Hardness Scale gave it 1912, which means it is harder than maple and red oak.

Amendoim wood stain 

The wood can take on a blue color. Blue stain can attack it when the air is humid. The wood is natural and hasn’t been stained, so they are almost mess-free and easy to put up.

Wood identification

Wood seems like a good, cheap, and easy way to get energy, but if it’s taken out of the ground uncontrolled, it can cause environmental problems like deforestation.

The yellowish-brown sapwood isn’t separated from the reddish-brown heartwood, which looks like mahogany and often has darker stripes.

The luster is medium to high, the texture is medium, the grain is often ropey, and it doesn’t have a smell or taste that stands out.

Color and appearance

Occasionally, darker streaks will cut through heartwood’s lighter brown or reddish brown color.

With time, the color tends to get darker. It’s not always easy to tell sapwood, pale yellowish brown, from heartwood.

Overall, it looks very much like mahogany.


Diffuse-porous, with medium pores that aren’t arranged in a certain way. Heartwood that is amber, reddish brown, or black. Amendoim wood structure comprises confluent axial parenchyma, diffuse porosity, tylosis, and heterogeneous.

The fibers were short (0.81 mm in length), not flexible, and had a Runkel index of 0.82. There were only 32.9 pores per mm2 of skin, and many of the pores were blocked by a condition called tylosis.


The inflorescence is an axillary panicle composed of three racemes of tiny flowers.

The peduncles of the inflorescence are yellow and hairy; they are brown at the base and white at the top, and there is a bract that falls off at the insertion of each pedicel.


Fruit is an achene winged with a pedicel on this thick seminiferous; the wing is connected to the pericarp by an oblique slit.

Some ribs stick out from the rear of the seed, and the wing itself has wings that are curled.

Grain and texture

Straight to interlocked grain, medium texture, and a high natural shine characterize this wood’s appearance.


The leaves are alternate, pinnate, and have 6 pairs of opposite folioles. The upper part of the petiole is sulcate, and the base has a strong pulvinus.

The folioles have short petioles, are oblong, smooth, shiny on top and opaque on the bottom, and have ribs and veins that stick out.


No characteristic odor.


Reaches a maximum height of over 100 feet, but most don’t grow taller than 75 feet. It has a well-formed trunk that is 2 to 3 feet in diameter and, in rare cases, 4 feet in diameter.

Pterogyne Nitens is a tree that loses its leaves every year. It has an open, rounded crown and grows 10–25 meters tall, sometimes even 30 meters. Most of the time, the bole is between 40 and 60 cm in diameter, but sometimes it can be up to 120 cm.

The tree’s wood is valuable, and it is cut down in the wild and sold all over the world. It can be used to plant new trees and is also sometimes grown as a decorative plant.

Amendoim wood bark

The bark on the wood is very thin, and it is easy to tell the difference between the outside bark and the inside bark.

The bark percentage compared to the tree’s diameter ranged from 5.1 (at the base) to 3.0% (at the top), making this a species with low bark content.

For industrial use, it is also important that the bark is the same thickness all along the tree.

Brazilian Oak (Couratari Tauari)

Brazilian Oak trees can grow up to 20 m tall. The trunk is not buttressed, and the young branches are hairy but soon lose their hair. The leaf blades are ovate to oblong-ovate and 8–15 x 3.5–8 cm. They are coriaceous and have sparse stellate hairs on the underside.

The flowers are in racemes up to 5 cm long, and the stems are covered with dark brown hairs. Couratari Tauri is only known from a few collections that are far apart from each other. Thanks to recent collections, a more accurate description of this species are now possible.

Natives roll up the inner bark and use it as a cigar. Greenwood has a strong smell that goes away quickly when it dries out.

Shining Gum/Silver Top (Eucalyptus nitens)

Eucalyptus nitens is a hardwood species that can survive in cold climates. In Canterbury and other cooler parts of New Zealand, E. nitens grows quickly and makes much sawlog-sized wood in a short amount of time.

Some farm foresters have even cut back their trees in preparation for making sawn wood. Logs gross about $50 per tonne when they are delivered.

After harvesting and shipping costs are taken out, the grower makes between $0 and $20 per year.
