樟科(Lauraceae)植物全世界约45属,2 000余种,主产热带和亚热带。我国有20属400余种,主产长江流域及以南地区[1]。四川原产12属82种,13变种[2]。该科植物是四川常绿阔叶林常见重要组成树种,也是具有重要经济价值的一个科,有的种类木材优良,有的种类含经济价值较高的油脂和芳香油,有的为营养丰富的水果,有的为食品香料,有的为著名的药物,有的为具有较高观赏价值的优良绿化树种。
2018年4月至2019年6月期间,在对四川盐源县林木种质资源普查过程中发现了2樟科植物,经现场拍照、记录相关信息并采集标本,通过详细鉴定后确定为樟科的贡山润楠(Machilus gongshanensis H. W. L)和红河木姜子(Litsea honghoensis Liou)。查阅了相关资料[3-6]及考证中国数字植物标本馆(https://www.cvh.ac.cn/)相关标本后,发现两者均为四川新记录种,现给予报道。

Abstract: Two newly recorded species of Lauraceae, Machilus gongshanensis H.W.Li and Litsea honghoensis Liou, were reported in Sichuan, China. Meanwhile, the identifications and discussion were made, and the relevant photos were provided. The voucher specimen were preserved in the Herbarium room (XIAS) of Xichang College. The two newly recorded species were endemic to China. This discovery not only enriched the diversity of Lauraceae plants in Sichuan, but also had certain guiding significance in studying the origin and diffusion routes of related groups.
