Based on specimens collected in Yinggehai, Hainan, China from 2013 to 2016, a stable epiphytic taxon is found on the surface of the individual of marine green alga Cladophora aokii Yamada. According to the morphological characteristics, the taxonomy of Cl. aokii and its epiphytes is carried out. There are some epiphytes attached on Cl. aokii Yamada including Cl. fascicularis(Mertens ex C. Agardh) Kützing, Chaetomorpha pachynema(Montagne) Kützing, Ceramium camouii Dawson, Licmophora abbreviata Agardh, Lyngbya sp. and Chattonella sp.. The formation of the individual of Cl. aokii is dissected and explained, which can help to analyze the adaption in details among this species, its epiphytes and native marine environment. The results reveal the marine macroepiphytic taxonomy in Hainan, China, and preliminarily explain the adaptive relationship between macroalgae and environment. 相似文献

针对国际上海洋绿藻束生刚毛藻Cladophorafascicularis与C.vagabunda的同物异名争议,本文对采集于海南岛莺歌海的束生刚毛藻进行了形态学观察。从55个样品的形态特征观测及分析中获得了用于其物种鉴定的主要特征为:藻体丛生,黄绿色,往往纠缠在一起,高3—23cm;基部为不规则分枝的假根状,往往多个植株的假根粘连在一起;直立部分叉状或多不规则叉状分枝,主枝可产生多个分枝或产生分级的分枝;上部枝多个密集成束,偏生于一侧,末位小枝侧生,多向内侧弯曲,略呈栉状排列,枝端钝尖;主轴细胞长宽比为3—6.5,侧枝细胞长宽比为3—5,小枝细胞长宽比为1.5—5,末位细胞长宽比为1.2—5。结合形态特征比较以及分子数据分析,本文探讨了束生刚毛藻与C. vagabunda的同物异名问题,认为束生刚毛藻可作为独立种存在。 相似文献
