科属（Family & Genus）：木犀科（Oleaceae）梣属
形态特征（Description）：落叶乔木，高10-12米；树皮灰褐色，纵裂。芽阔卵形或圆锥形，被棕色柔毛或腺毛。小枝黄褐色，粗糙，无毛或疏被长柔毛，旋即秃净，皮孔小，不明显。羽状复叶长15-25厘米；叶柄长4-6厘米，基部不增厚；叶轴挺直，上面具浅沟，初时疏被柔毛，旋即秃净；小叶5-7枚，硬纸质，卵形、倒卵状长圆形至披针形，长3-10厘米，宽2-4厘米，顶生小叶与侧生小叶近等大或稍大，先端锐尖至渐尖，基部钝圆或楔形，叶缘具整齐锯齿，上面无毛，下面无毛或有时沿中脉两侧被白色长柔毛，中脉在上面平坦，侧脉8-10对，下面凸起，细脉在两面凸起，明显网结；小叶柄长3-5毫米。圆锥花序顶生或腋生枝梢，长8-10厘米；花序梗长2-4厘米，无毛或被细柔毛，光滑，无皮孔；花雌雄异株；雄花密集，花萼小，钟状，长约1毫米，无花冠，花药与花丝近等长；雌花疏离，花萼大，桶状，长2-3毫米， 4浅裂，花柱细长，柱头2裂。翅果匙形，长3-4厘米，宽4-6毫米，上中部最宽，先端锐尖，常呈犁头状，基部渐狭，翅平展，下延至坚果中部，坚果圆柱形，长约1.5厘米；宿存萼紧贴于坚果基部，常在一侧开口深裂。花期4-5月，果期7-9月。
分布（Distribution）：产于南北各省区，多为栽培，也见于海拔800-1600米山地杂木林中。越南、朝鲜也有
用途（Use）：主要经济用途为放养白蜡虫生产白蜡，材理通直，生长迅速，柔软坚韧，供编制各种用具；树皮也作药用。

白蜡树 bai la shu| Oleaceae | Fraxinus
Trees 3-20 m. Branchlets glabrous, sparsely villous puberulent or tomentose; buds broadly ovoid or conical, brown tomentose, pubescent or glandular hairy. Leaves 12-35 cm; petiole 3-9 cm; axis puberulent or pilose at first, leaflet joint glabrous or densely tomentose; leaflets 3-7(-9); petiolule 2-15 mm; leaflet blade broadly ovate, ovate, to lanceolate or elliptic to obovate-lanceolate, 4-16 × 2-7 cm (terminal much larger), papery to somewhat leathery, glabrous or villous, sometimes villous only along veins abaxially, base blunt or cuneate, margin regularly serrate to crenate-serrate, sometimes entire in lower half, apex acute to long acuminate or caudate; primary veins 5-10 on each side of midrib. Panicles terminal or lateral, 5-10 cm. Flowers dioecious, opening with leaves. Staminate flowers congested; calyx cupular, 1-1.5 mm; corolla absent. Pistillate flowers lax; calyx tubular, 2-3 mm. Samara spatulate to very narrowly so, 2.5-4 cm × 3-7(-15) mm; wing decurrent to middle or lower part of nutlet.
Slopes, along rivers, roadsides, mixed woods; 800-2300 m. Throughout China [Japan, Korea, Russia, Vietnam]
