红树植物厦门老鼠簕(爵床科)的订正

重新检查了厦门老鼠簕的主模式和副模式标本后,发现原始文献对其鉴别特征"花……具两个苞片,无小苞片"描述有误,应改为"花……具两个小苞片,一个苞片"。基于标本室和野外观察,认为厦门老鼠簕在老鼠簕的正常变化范围之内,应归并到老鼠簕;不赞同把厦门老鼠簕降级为小花老鼠簕或毛鼠簕的变种的处理。报道了一个新异名Acanthusilici folius var.xiamenensis。

A note on a mangrove Acanthus xiamenensis(Acanthaceae)

After the holotype and paratypes of Acanthus xiamenensis had been rechecked,the author found the diagnostic character "foliis……bracteis 2 oppositis instractis ebracteolatis" was wrongly described in original paper,and it should be revised as "foliis……bracteis 1,bracteolatis 2 oppositis".Basing on herbaria and field observations,the authors argue that A.xiamenensis was fallen to the varieties of A.ilicifolius,and should be reduced to A.ilicifolius,and did not agree to the treatment that A.xiamenensis was degraded into a variety of A.ebracteatus or A.ilicifolius.A new synonym Acanthus ilicifolius var.xiamenensis was reported.
