小喬木。小枝圓柱形,被短柔毛。芽長圓形,被絲毛,銳尖,長6-10毫米,直徑2-3 毫米。葉長圓形或披針形,長6-9釐米,寬1.3-2.3釐米,先端銳尖,基部銳尖或楔形,革質,上面無毛,下面在中脈基部被長柔毛,側脈每邊約5條,上面稍為突起,下面明顯突起,小脈下面明顯突起;葉柄纖細,長7-10毫米,被短柔毛。果序腋生,呈傘形;總梗長3毫米。果橢圓形,長3毫米,直徑2.5-3毫米,無毛;宿存花被片外面被短柔毛,先端截形;果梗長1-2毫米。(標本未見,摘自原描寫) 產我國臺灣(屏東大武山)。生於海拔2400米的林中。
張慶恩認為本種近於Litsea morrisonensis Hay.[=玉山黃肉楠Actinodaphne morrisonensis (Hay.) Hay.],但不同在於葉近于無毛,小脈在葉下麵明顯突起,果序有較長的總梗。我們看來,兩者區別特徵並不明顯,況且後者已移入黃肉楠屬,因此本種能否建立,若能建立宜置於何屬的問題均應加予考慮。由於我們未見標本,附志於此,留待考訂。
