科属（Family & Genus）：菊科Compositae泽兰属Eupatorium
形态特征（Description）：多年生草本，高50-150厘米。根茎粗壮，有节，生多数细根。茎直立，全部或下部淡紫红色，不分枝或仅在茎顶有伞房状花序分枝，茎基部径达5厘米；全部茎枝被短柔毛，花序分枝及花梗上的毛较密，花期中下部脱毛。叶对生，有短柄，柄长0.5厘米；中下部茎叶三全裂；中裂片大，长6-11厘米，宽2-3厘米，长椭圆形或长披针形，基部楔形或宽楔形，顶端渐尖或长渐尖，侧生裂片小，与中裂片同形。上部茎叶渐小，三全裂或不分裂，下部茎叶花期脱落。全部茎叶两面粗涩，质地稍厚，被稀疏白色短柔毛及腺点，下面及下面沿脉的毛较密，羽状脉，侧泳5-6对，边缘有锯齿。头状花序多数在茎顶及枝端排成密集的复伞房花序，花序径5-8厘米。总苞钟状，长6毫米，含3-7个小花；总苞片9-10个，2-3层，覆瓦状排列；外层短，卵状披针形，长2毫米，外面被短柔毛；中内层苞片渐长，披针形，长5-6毫米，边缘膜质，顶端急尖并染紫红色。花紫红色、粉红色或淡白色，花冠长约5毫米，外被稀疏黄色腺点。瘦果黑褐色，圆柱状，长3毫米，5棱，散布黄色腺点；冠毛白色，长约5毫米。
分布（Distribution）：此种遍布全欧洲及北非洲，苏联西伯利亚地区、高加索地区也有分布。我国江苏宜兴、浙江杭州有记录，可能是引种归化的种。生小山山顶、山坡草丛或村落竹林内。

大麻叶泽兰 da ma ye ze lan| Asteraceae | Eupatorium
Eupatorium nodiflorum Wallich ex Candolle.
Herbs, perennial, 50-150 cm tall. Rhizomes robust, with many fibrous roots. Stems erect, purplish red, simple or only apically corymbose branched, puberulent; synflorescence branches and peduncles more densely hairy, glabrescent in median lower part by anthesis. Leaves opposite, shortly petiolate; petiole ca. 5 mm; median and lower leaves irregularly lobed; central lobe elliptic or narrowly lanceolate, large, 6-11 × 2-3 cm, base cuneate or broadly cuneate, apex acuminate or long acuminate; lateral lobes same shape as central lobe, smaller; upper stem leaves gradually smaller, irregularly lobed or simple; lower stem leaves shed by anthesis; all stem leaves scabrid, rather thick, sparsely puberulent and glandular, more densely hairy abaxially and on veins, pinnately veined, lateral veins 5- or 6-paired, margin serrate, undulate. Synflorescences terminal, of densely compound corymbs. Capitula numerous, 3-7-flowered; involucre campanulate, ca. 6 mm; phyllaries 2- or 3-seriate, imbricate; outer phyllaries short, ovate-lanceolate, ca. 2 mm, puberulent; median and inner phyllaries gradually longer, with membranous margin and purplish tip; corollas purple-red, pink, or whitish, ca. 5 mm, outside sparsely yellow glandular. Achenes black-brown, cylindric, ca. 3 mm, 5-ribbed, with yellow glands; pappus setae white, ca. 5 mm. 2n = 20.
Summits of small hills, grasslands, among bamboos. Jiangsu, ?Taiwan, Zhejiang, may be introduced and naturalized [Europe].
