乔木，通常高8-12米。当年生枝密被黄灰色长柔毛，二年生枝有短疏柔毛或近于无毛。叶薄革质，干时常为栗色，披针形或椭圆状披针形，长9-18(22)厘米，宽(2) 2.5-5.5厘米，先端尾状渐尖，基部渐狭，通常下延，上面无毛，下面初时密被灰白色或灰褐色长柔毛，后变短柔毛，脉上仍有疏长柔毛，中脉上面突起，侧脉细，每边10-15条，近边缘网结并消失，上面不明显或略明显，下面明显，横脉及小脉下面隐约可见；叶柄长1-2厘米，被短柔毛。圆锥花序多个，生于新枝上部叶腋内，长短变化较大，通常长9-16厘米，少数可达25厘米，在顶端分枝，总梗及各级序轴均密被黄灰色柔毛；花长4-5毫米，花梗约与花等长；花被片卵形；先端钝，两面被黄褐色柔毛；能育雄蕊各轮花丝被毛，第三轮毛更密，腺体无柄或近无柄，着生在第三轮花丝基部，退化雄蕊具柄，密被长柔毛；子房近球形，无毛或上半部有疏柔毛，花柱丝状，直或略弯，柱头盘状。果椭圆状倒卵形或椭圆形，长约1.2厘米；果梗短，增粗；宿存花被片紧贴，两面被毛或外面近无毛。花期通常2-3月，果期5-8月。
产广东、广西东南部、云南。生于混交林及灌丛中，在海南岛尤为普遍。分布于印度、缅甸、老挝、泰国、柬埔寨、越南、马来西亚及印度尼西亚等。
木材坚实，耐水浸，不易开裂及虫蛀，为船板、建筑、水桶等良好木材。
本种分布广，叶的大小变异幅度较大。国产标本中，大的宽达6厘米，小的宽1.5厘米，一般为3.5-4厘米。产于海南岛并定作Phoebe henryi(Hemsl.) Merr.的标本，与产于印度、缅甸、马来半岛等地并定作P. tavoyana (Meissn.) Hook. f.的标本完全一致，只是我国的标本少数个体叶较狭小而已，不必另立一种，应归并。

Trees, usually 8-12 m tall. Two-year-old branchlets sparsely pubescent or glabrate; current year branchlets densely yellow-gray villous. Petiole 1-2 cm, pubescent; leaf blade lanceolate or elliptic-lanceolate, 9-22 × 2.5-5.5 cm, thinly leathery, abaxially densely gray-white or gray-brown villous becoming pubescent, adaxially glabrous, midrib adaxially elevated, lateral veins 10-15 pairs, anastomosing and disappearing near margin, abaxially distinct, adaxially indistinct or slightly distinct, veinlets somewhat visible, base attenuate, usually decurrent, apex caudate-acuminate. Panicles numerous, axillary at upper part of newly sprouted branchlet, usually 9-16 cm, rarely to 25 cm, branched on top, densely yellowish gray pubescent. Flowers and pedicel 4-5 mm. Perianth yellowish brown, ovate, pubescent on both surfaces, apex obtuse. Filaments hairy, those of 3rd series with sessile or subsessile glands at base. Staminodes stipitate, densely villous. Ovary subglobose, glabrous or sparsely pubescent at upper part; style filiform, erect or somewhat curved; stigma dish-shaped. Fruit ellipsoid-obovoid or ellipsoid, ca. 1.2 cm; fruiting pedicel short, thickened; persistent perianth hairy on both surfaces. Fl. usually Feb-Mar, fr. May-Aug.
