''Dalbergia nigra'', commonly known as the Bahia rosewood, jacarandá da Bahia, Brazilian rosewood, Rio rosewood, jacarandá de Brasil, pianowood, caviuna, or obuina, is a species of legume in the Fabaceae family. ==Description== ''Dalbergia nigra'' produces a very hard and heavy wood, characteristically varied in color from brick red through various shades of brown (medium to nearly black). Pieces that feature veins of black coloration called ''spider webbing'' or ''landscape grain'' are especially prized. Brazilian rosewood has a distinctive floral fragrance—reminiscent of roses with a distinctive sweetness—and strongest in old growth wood. Another distinguishing feature is its outstanding resonance. An evenly cut piece that is tapped emits a bright metallic ring that sustains. This property, combined with its beauty, has made Brazilian rosewood a favorite of musical instrument makers for centuries. Brazilian rosewood is highly resistant to insect attacks.〔 There are many species in the ''Dalbergia'' genus that can be confused with ''Dalbergia nigra'', but the latter can be recognised by its colour and resin.〔(Amendments to Appendices I and II of The Convention - Other Proposals ) CITES. March 1992.〕 It may also be confused with ''Machaerium'', which has a more compact parenchyma and lack large pores.〔 Very little is known about the ecology and reproduction of the Brazilian rosewood.〔ARKive on Brazilian Rosewood〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dalbergia nigra」の詳細全文を読む スポンサード リンク
