The tulipwood is the timber of Dalbergia decipularis , a species from the genus of dalbergia ( Dalbergia ) within the family of the Leguminosae (Fabaceae). It only occurs in Brazil and provides a reddish wood that is very valuable due to its special color and quality. The name rosewood is derived from the rose-like scent of the freshly cut wood as well as from its rapidly fading, intensely reddish color. It is also called Bahia rosewood after the Brazilian export port of Bahia , from which it was mainly shipped in the 18th and 19th centuries. Since January 2017 it has been subject to the Washington Convention on Endangered Species .

The Bahia rosewood is also supplied by ( Dalbergia frutescens ).

Dalbergia decipularis grows as a tree and reaches heights of up to 10–12 meters and trunk diameters of up to about 0.4–0.5 meters. The bark is grayish-brown and slightly furrowed.

The short stalked, short foliage leaves are alternately pinnate with 5–9 slightly leathery, almost bare leaves . The rounded or round-pointed, partly indented and entire, almost sessile, egg-shaped to elliptical leaflets are about 2.5–5.5 inches long and up to 2.5 inches wide.

Axillary, short and zymous, brownish hairy inflorescences are formed. The butterfly flowers are whitish.

Flat, winged, single-seeded, with wings up to 5 centimeters long and elliptical fruits with a central, elliptical to round seed are formed.

distribution

The Dalbergia decipularis is native to Brazil only.

Rosewood
Grain

The wood color is a yellowish pink with irregular reddish stripes, the sapwood (the relatively young, outer layer under the bark) is yellowish. The wood is very hard, dense and brittle, it can be worked and polished well. The resistance to fungi and insects is great.

Due to its very low lightfastness, rosewood is only used in light-protected applications, mostly inside furniture, because under the influence of sunlight the red changes very quickly into a straw-like and structureless yellow.

Even in the furniture industry of the 18th century, rosewood was considered to be particularly valuable and expensive "pound wood", which, because of its rarity, was traded by weight and not - as is usually the case - by volume. Its comparatively high price rarely allows it to be used as solid wood; it is used for profiles, veneered surfaces and inlays . The wood is used in furniture construction , for luxury small objects such as humidors and for the production of musical instruments . In guitar making, back and sides are sometimes made of rosewood instead of maple or rosewood ; Baroque recorders are sometimes made of rosewood.

Mix-ups

Since the introduction of this wood into the European market in the 16th century, the English word rosewood has been mistakenly translated into German as rosewood. In English usage, the term rosewood is used as a generic term for almost all wood of the genus Dalbergia that is called rosewood in German . In order to create conceptual clarity, the species are almost always specified with a geographical designation of origin:

Deviating from this logic, Bahia rosewood ( Dalbergia decipularis ) and ( Dalbergia frutescens ) are also referred to as Brazilian tulipwood or pinkwood in English , which makes it difficult to distinguish it from American tulipwood from the North American tulip tree ( Liriodendron tulipifera ), English tulip tree . The wood of Harpullia pendula and Harpullia arborea is also known as Australian Tulipwood .

The trade names Brazilian Tulipwood and Pinkwood generally refer to rosewood species in the timber trade. The French bois de rose can also refer to the tree species Aniba rosaeodora (laurel family) and other Dalbergien species. To distinguish it, Bois de rose is used for Dalbergia species and Bois de rose femelle for Aniba rosaeodora u. a. used.

Protection status

Since January 2017, Dalbergia decipularis, together with the other species of the genus Dalbergia, has been subject to the Washington Convention on Endangered Species and is listed together with all other Dalbergia in Appendix II ; The only exception so far is the Rio rosewood ( Dalbergia nigra ), which is more protected due to the greater threat of inclusion in Appendix I.
