鱗花木形態特徵
喬木，高達12米；小枝粗壯，節間常很短，稍曲折，灰黃色，近無毛。
偶數羽狀複葉，稍密集，葉軸粗壯，與小枝近同色，柱狀，長15-34厘米，有直線紋，無毛；小葉4-6對，革質，長圓狀披針形至橢圓狀卵形，長6-20厘米，寬2-6厘米，第一對（近基) 明顯較小，頂端短漸尖或有時驟尖，基部闊楔形至鈍，全緣，兩面無毛，稍有光澤，干時腹面欖綠色，背面淡茶褐色；中脈、側脈和網脈均兩面凸起，側脈稍密，約15-22對，近邊緣處彎拱上升，不明顯網結；小葉柄粗壯，腹面有深溝，長約1厘米。
花序腋生或生無葉老枝上，長可達30厘米，密被柔毛，花序軸稍粗壯，有稜角，分枝開展；花蕾近球形，直徑約5毫米；萼片5，近圓形或闊倒卵形，凹陷，邊緣薄，背面被絨毛；花瓣，或有時4，上部楔狀圓形，下部漸狹，有爪，長7-8毫米，寬4-5毫米，邊緣常齧蝕狀，僅背面基部被白色長毛，鱗片邊緣與花瓣邊緣合生，頂部2裂，被白色頂毛，有冠狀附屬體；花盤偏於一邊，常3裂，裡面無毛，外面被絨毛；雄蕊8或有時7，稍伸出，花絲密被毛；子房3室，被絨毛，花柱粗壯，柱頭頭狀。果（未充分成熟) 有粗而短的梗，近球狀，直徑最大達2厘米，通常3室，室間無明顯的凹槽，果皮革質，外面被灰色短絨毛，內面無毛；種子每室1顆。

Trees, to 12 m tall. Branches grayish yellow, slightly zigzag, strong, stout, internodes often very short, subglabrous. Leaves paripinnate, slightly dense, axis strong, nearly concolorous with branches, terete, 15-34 cm, striate, glabrous; leaflets 4-6 pairs; petiolules ca. 1 cm, strong, stout, adaxially deeply furrowed; blades abaxially pale brown when dry, adaxially slightly shiny, olive-green, oblong-lanceolate to elliptic-ovate, 6-20 × 2-6 cm, first pair (near base) evidently smaller, leathery, glabrous, midvein, lateral, and reticulate veins prominent on both sides, lateral veins slightly denser, 15-22 pairs, arched and ascending near margin, inconspicuously netted, base broadly cuneate to obtuse, margin entire, apex shortly acuminate or cuspidate. Inflorescences axillary or on leafless old branches, to 30 cm, densely pilose, rachis slightly stout, ridged, branches spreading. Flower buds subglobose, ca. 5 mm. Sepals 5, suborbicular or broadly obovate, concave, margin thin, abaxially tomentose. Petals 5 or sometimes 4, upper part cuneate-orbicular, lower part gradually narrowed, 7-8 × 4-5 mm, abaxially only long white hairy at base, clawed, margin erose; scales connate with petals at margin, apex 2-lobed, white ciliate, with cristate appendage. Disk oblique, usually 3-lobed, abaxially tomentose, adaxially glabrous. Stamens 8 or sometimes 7, slightly exserted; filaments densely hairy. Ovary 3-loculed, tomentose; style stout; stigma capitate. Fruit (not thoroughly mature) with a short, stout stalk, subglobose, to 2 cm in diam., usually 3-loculed; pericarp leathery, abaxially shortly grayish tomentose, adaxially glabrous. Seeds 1 per locule. Fr. Jun-Jul.
