浙江所产的白膠香,它的原植物屬于金缕梅科的楓香树(Liqudambar formosana),中国药学大辞典,列为漆树科,与实际有出入。该植物是一种自生山地的落叶乔木。树身高聳,可达15—20米,直徑0.5—1米左右,幼树栓皮表面呈灰褐色而平滑,老时变褐色,外皮显得很粗糙。叶互生,嫩叶多作五裂,基部掌狀,边緣有小鋸齿,叶片初为綠色,深秋时往往会转紅黄色而脫落。花單性,雌雄同株,雄花成总狀花序,无花萼及花冠,雌花为球形头狀花序,花梗細長。果实为莉果,外面密被多数毛刺,是由細長宿存的花柱和苞片愈合而成,成熟后呈暗褐色,采收亦供药用,称“路路通”(但一般多自幼树间采摘,故产量較多)。
The white gum aroma produced in Zhejiang Province belongs to Liqudambar formosana, a Chinese medicine pharmacy dictionary, which is classified as a lacquer tree family and is different from the actual one. The plant is a kind of deciduous tree in its own mountain. The tree is tall, up to 15-20 meters, 0.5-1 meters in diameter, and the cork of the sapling is grey-brown and smooth. It turns brown when old, and the skin appears rough. The leaves are alternate, and the young leaves are more than five cracks. The base is palmate, with small serrations on the edges, and the leaves are green at first. In late autumn, they often turn reddish yellow and fall off. Flower unisexual, monoecious, male flowers into a racemose, without calyx and corolla, female flowers are spherical head inflorescences, pedicels slender. The fruit is Liguo, surrounded by most of the burrs, and it is made up of slender, persistent styles and sepals. It matures in dark brown and is harvested for medicinal use. It is called “Road Pass” (but usually more than one child. Picking between trees, so more production).
