摘　　要：报道国家Ⅱ级保护植物疏花水柏枝[Myricaria laxiflora(Franch.)P.Y.Zhang&Y.J.Zhang]的6个新分布种群,分布于四川省宜宾市叙州区和翠屏区境内岷江江岸和江心岛的鹅卵石滩上。首次在岷江流域发现其自然分布种群,也是迄今发现的最上游的种群。该发现拓宽了该物种的分布范围,对该物种的保护具有重要意义。凭证标本现保存于宜宾学院植物标本室(GAO2022003)。Six new distribution populations of Myricaria laxiflora(Franch.)P.Y.Zhang&Y.J.Zhang were reported,which is a nationalⅡ-class protective plant.These populations are distributed in pebble beach of Minjiang River in Xuzhou District and Cuiping District,Yibin City,Sichuan Province.This is the first time that a naturally distributed population has been found in the Minjiang River,and these populations are also the most upstream population.By this discovery,the distribution area of the species was broadened,that is of great significance for the conservation of the species.The voucher specimen(GAO2022003)was preserved in the herbarium room of Yibin University.
