[医]珊瑚属是Cortocyanoideae（Aresch.）Foslie和Cordella officinalis L.是该属的模式种。这个名字已经在世界范围内应用，特别是在温带沃茨。尝试从选择型标本中获得序列数据未成功。为了建立C.基于分子序列数据以及形态学，从英国德文郡郡的模糊模式产地“欧洲O [奥恰诺]”中选择一个表型，并从中获得线粒体（cox 1）和质体（rbcL）数据。第二个种，Cordella elongata Ellis et Solander（模式产地康沃尔，英格兰），先前基于DNA序列显示包括至少两个物种。C. elongata是一个例证，因此选择一个表型来提供分子序列数据，使用与C.药用植物C. officinalis和C. elongata与第三种最近描述的来自英国的物种Cordella caespitosa R. H.步行者，J. Brodie et L. M.欧文：这些数据为研究世界其他地区的珊瑚虫物种分类和多样性提供了一个例子。这项工作的影响进行了讨论有关的物种分布的概念。
Corallina L. is the type genus of the subfamily Corallinoideae (Aresch.) Foslie and Corallina officinalis L. is the type species of the genus. This name has been applied worldwide, particularly in temperate waters. An attempt to obtain sequence data from the lectotype specimen was not successful. In order to establish a species concept for C. officinalis based on molecular sequence data as well as morphology, an epitype was selected from Devon, England within the vague type locality 'in O [Oceano] Europaeo', and from which mitochondrial (cox1) and plastid (rbcL) data were obtained. A second species, Corallina elongata Ellis et Solander (type locality Cornwall, England), was shown previously to include at least two species based on DNA sequences. The lectotype of C. elongata is an illustration and therefore an epitype was selected to provide molecular sequence data, using the same markers as for C. officinalis. These molecular sequences for C. officinalis and C. elongata are compared with those of a third, recently described species from Great Britain, Corallina caespitosa R. H. Walker, J. Brodie et L. M. Irvine: these data provide an example for studying Corallina species taxonomy and diversity in other parts of the world. The implications of this work are discussed in relation to concepts of species distribution.
