在珊瑚藻亚科Melobesioideae的属中，LeptophytumAdey和PhymatolithonFoslie可能是近年来最有争议的属。在最近的出版物中，Leptophytum的名称被用在引号中，因为南非归于该属的分类群还没有正式转移到另一个属或减少到同义。并对这些种的地位和属的分布进行了讨论。acervatum，L.菲罗克斯湖自Düwel和Wegeberg（1996）通过对相关类型和其他标本的研究确定LeptophytumAdey是PhymatolithonFoslie的异型异名以来，一直没有得到解决。根据我们对最近收集的大量标本和有关类型的已发表数据的研究，我们得出结论，上述每一个先前归属于Leptophytum的种都代表了Phymatolithon的一个不同种，（包括P. repandum）ofPhymatolithon是目前已知的发生在南非。在这里，我们提出了详细的说明帐户的四个物种，包括：新的数据对男性和女性/carposporangial conceptides;生态和形态/解剖比较;和审查的信息上的各种功能以前用于separateLeptophytumandPhymatolithon。属于Phymatolithon属的南部非洲物种在野外可能会根据其生长形式、通常发现它们的基质以及活菌体的颜色而彼此分开。一个关键的识别南部非洲标本在外地包括在内。我们的数据支持Leptophytumis所依据的特征不足以作为Phymatolithon属的划分依据的结论。
Of the genera within the coralline algal subfamily Melobesioideae, the generaLeptophytumAdey andPhymatolithonFoslie have probably been the most contentious in recent years. In recent publications, the nameLeptophytumwas used in quotation marks because South African taxa ascribed to this genus had not been formally transferred to another genus or reduced to synonymy. The status and generic disposition of those species (L. acervatum,L. ferox,L. foveatum) have remained unresolved ever since Düwel and Wegeberg (1996) determined from a study of relevant types and other specimens thatLeptophytumAdey was a heterotypic synonym ofPhymatolithonFoslie. Based on our study of numerous recently collected specimens and of published data on the relevant types, we have concluded that each of the above species previously ascribed toLeptophytumrepresents a distinct species ofPhymatolithon, and that four species (incl.P. repandum) ofPhymatolithonare currently known to occur in South Africa.Here we present detailed illustrated accounts of each of the four species, including: new data on male and female/carposporangial conceptacles; ecological and morphological/anatomical comparisons; and a review of the information on the various features used previously to separateLeptophytumandPhymatolithon. Southern African species ascribed to the genusPhymatolithonmay be separated from one another in the field by their growth forms, the substrata on which they are generally found, and the colour of living thalli. A key for identifying southern African specimens in the field is included. Our data support the conclusion that the characters upon whichLeptophytumis based are unreliable for generic delimitation fromPhymatolithon.
