形态特征(Description):乔木,高可达20余米;皮孔圆形至椭圆形;枝具小疣点。叶平展,二回羽状复叶,长45-70厘米;叶轴和叶柄向轴面常有一纵行皱曲的短柔毛;小叶9-17片,互生,很少对生,纸质或近革质,斜卵形,长3.5-7厘米,宽2-3.5厘米,顶端短尖至短渐尖,基部阔楔形或圆形,略偏斜,边缘有内弯的小锯齿,两面无毛或上面中脉上被微柔毛,下面密被短柔毛,有时杂以皱曲的毛;小叶柄长约3毫米或近无柄。圆锥花序大型,长35-70厘米,分枝广展,与花梗同被短柔毛;萼5裂达中部,裂片阔卵状三角形或长圆形,有短而硬的缘毛及流苏状腺体,边缘呈啮蚀状;花瓣4,长圆状披针形,瓣片长6-9毫米,宽1.5-3毫米,顶端钝或短尖,瓣爪长1.5-3毫米,被长柔毛,鳞片深2裂;雄蕊8枚,长4-7毫米,花丝被白色、开展的长柔毛,下半部毛较多,花药有短疏毛;子房三棱状长圆形,被柔毛。蒴果椭圆形或近球形,具3棱,淡紫红色,老熟时褐色,长4-7厘米,宽3.5-5厘米,顶端钝或圆;有小凸尖,果瓣椭圆形至近圆形,外面具网状脉纹,内面有光泽;种子近球形,直径5-6毫米。花期7-9月,果期8-10月。
分布(Distribution):产云南、贵州、四川、湖北、湖南、广西、广东等省区,生于海拔400-2500米的山地疏林中。
用途(Use):速生树种,常栽培于庭园供观赏。木材可制家具;种子油工业用。根入药,有消肿、止痛、活血、驱蛔之功,亦治风热咳嗽,花能清肝明目,清热止咳,又为黄色染料。

Koelreuteria bipinnata var. puberula Chun; K. bipinnata var. integrifoliola (Merrill) T. C. Chen; K. integrifoliola Merrill.
Trees, to 20 m tall. Branches tuberculate, lenticels orbicular to elliptic. Leaves spreading, bipinnate, 45-70 cm; axis and adaxial surface of petiole often with one line appressed pu-bescent; leaflets 9-17, alternate, rarely opposite; petiolules ca. 3 mm or leaflets subsessile; blades obliquely ovate, 3.5-7 × 2-3.5 cm, papery or subleathery, abaxially densely pubescent or sometimes mixed with appressed hairs, adaxially glabrous or pilosulose on midvein, base broadly cuneate or rounded, slightly oblique, margin incurved serrate or sometimes entire. Thyrses spreading, large, 35-70 cm, pubescent with pedicels. Calyx 5-lobed to middle; sepals broadly triangular or elliptic, hispidulous and fimbriate glandular, margin erose. Petals 4, oblong-lanceolate, 6-9 × 1.5-3 mm, apex obtuse or acute, claw 1.5-3 mm, villous; scales deeply 2-lobed. Stamens 8, 4-7 mm; filaments spreading white villous; anthers short and sparsely hairy. Ovary trigonous-ellipsoid, pilose. Capsules pale purplish red, brown when mature, ellipsoid or subglobose, 3-ridged, 4-7 × 3.5-5 cm, apex obtuse or rounded, mucronate; carpels ellipsoid to subcordiform, abaxially reticulate veined, adaxially shiny. Seeds subglobose, 5-6 mm in diam. Fl. Jun-Sep, fr. Aug-Oct.
