中新网成都8月8日电 (记者 刘忠俊)记者8日从眉山市生态环境局获悉，科研人员此前在眉山开展生态监测时发现的凤仙花属新物种，被命名为“眉山凤仙花(Impatiens meishanensis)”。相关研究成果已发表于国际知名植物分类学期刊《PhytoKeys》，为全球凤仙花家族增添新成员。
据了解，这一发现源于四川省生态环境监测总站、四川师范大学、眉山生态环境监测中心站联合开展的生态质量样地监测项目。科研团队在眉山市域内进行植被调查时，首次发现该未知凤仙花物种。经过形态特征比对、DNA分子测序等多轮科学验证，最终确认其为从未被记录的新物种。
眉山凤仙花为多年生草本植物，株高40至80厘米，卵形叶片边缘呈锯齿或波浪状，叶面光滑；粉紫色花朵长达4厘米，花瓣表面带有独特亮色；下萼片呈舟状，长1.5厘米至3厘米，向后延伸形成直距；椭圆形种子的种皮则布满网状纹饰。这些特征使其与同属其他物种形成明显区分。目前，已知分布于洪雅县瓦屋山风景名胜区，生长于海拔1990米左右的山间小道旁，偏好湿润的岩石土壤环境。
科研人员表示，眉山凤仙花的发现，对于区域植物生态适应机制和遗传多样性研究具有重要价值，是生态保护工作成效的直接体现，对区域生物多样性保护、生态保护修复以及生态系统多样性稳定性持续性提升具有重要意义。(完)
