古代重视有香气的草木。《说文解字》“兰,香草也。”陆玑《毛诗草木疏》说兰“其茎似药草泽兰,广而长节。汉诸池苑及许昌宫中皆种之。”至于蕙,晋嵇含《南方草木状》“蕙,一名薰草。”屈原《离骚》“余既滋兰之九畹兮,又树蕙之百亩。”好象兰蕙在战国时代已大规模人工种植,有点不可思议。其实,其中有一个很大的违反“植物命名规则”的问题。宋朱熹在《楚辞辨证》指出《楚辞》里的 Ancient emphasis on the fragrant vegetation. “Shuo Wen Jie Zi” “Lan, vanilla also.” Lu Ji, “Ma poem grass sparse,” said Lan “its stem like medicinal Zeeland, wide and long section. Han Zhu Chi Court and Xuchang Gongzhong are species.” As for Hui, Jin Huan with “southern vegetation” “LOH, a smoked grass.” Qu Yuan “Lisao” “Yu is not only Nirvana Xi Xi, but also the tree acres of acres.” It seems Lanyu in the Warring States era has been large Scale artificial planting, a little weird. Actually, there is a big problem that violates the “Plant Naming Rules.” Song Zhu Xi pointed out “Chu Ci” in “Chu Ci”
