  白酸枝學名:奧氏黃檀

  白酸枝宏觀特征:心邊材區別明顯,邊材黃白色,心材新切面淺紅色至深紅褐色,常帶明顯的黑色條紋。生長輪略明顯。管孔肉眼下可見。導管中常含黃褐至紅褐樹膠,軸向薄壁組織豐富,肉眼下明顯、帶狀、翼狀,與木射線交叉呈網狀結構略明顯。波痕放大鏡下明顯。新切面木材具酸味。木刨花或木屑酒精浸出液呈紅褐色。宏觀上區分白酸枝與黃花梨的要點在于:放大鏡下二者橫切面軸向薄壁組織顯著差異,白酸枝橫切面薄壁組織與射線成網狀,而黃花梨薄壁組織輪界狀,聚翼狀;白酸枝無特殊香氣,具酸味油脂感較弱,而黃花梨具辛辣香味,油性強;白酸枝板面具豐富的雞翅紋理,而黃花梨無此特征;白酸枝密度較黃花梨略大,白酸枝制品較黃花梨更沉。
