Overview
Abolboda americana为黄眼草科蓝花草本,原产南美洲北部湿地及桌山生境。植物学指南。
Abolboda americana为黄眼草科(Xyridaceae)莎草目(Poales)多年生草本。种加词americana泛指其分布于美洲大陆,该种隶属于Abolboda属,为新热带区特有属,主要集中分布于圭亚那高地及南美洲北部周边低地。作为黄眼草科成员,Abolboda americana为草状或灯芯草状草本,适应桌山(tepui)生态系统中开阔、积水、养分贫瘠的典型生境,这类生境包括古老砂岩台地的顶部平原、白沙稀树草原及排水不良的雅诺斯(llanos)平原。植株形成狭叶莲座丛或丛簇,抽生纤细花葶,顶端着生头状或穗状顶生花序。花朵典型为三瓣,呈蓝色或紫色,在花序整个花期中依次开放,每朵仅维持数小时。传粉主要由蜂类完成。果实为小型蒴果,内含大量微小种子,通过其所栖息湿地中的风力或水流传播。与同属其他物种相似,Abolboda americana为寡营养积水生境的专性种,在排水条件或土壤化学性质发生改变的环境中难以存续。南美洲的桌山地区是Abolboda属多样性最高之处,也是地球上最古老、植物学上最独特的景观之一,其特有植物区系具有重大的科学与保护价值。
