南澳大利亚族Crouanieae Schmitz(鹿科)的一个种。红藻门)，特别参照它们的分类关系进行研究。和系统发育；在所有情况下都对模式标本进行了检查。三个部落。克鲁亚亚科。安提萨姆尼耶。和异翅亚科。可以被认出。其中包括16属。其中Euptilocladia属。Macrothamnion。Tetuathamnion。Amoenothamnion。和Trithamnion为新记述种，48种(26新记述)。文章题目库拉尼奥亚科和角鲨亚科的再认识。正如Hommerand(1963)所定义的。最具分类学意义的特征也是那些指示系统发育趋势的特征，因此分类是基于系统发育的概念。形态和生殖特征的进化进步都涉及特化，特别是在形式上与功能相关的适应方面。Crouanieae、Anthamnieae和Heterotharnieae可能是Ceramiaceae的原始类群。Anthamnieae和Heterothamnieae关系密切，可能起源于同一进化谱系，而Crouanieae则独立进化。异毛菌亚科的菌体比最高级的异毛菌亚科中的那些种小，专化度低，很可能是异毛菌亚科的一个分支是通过生殖特征的专化而不是菌体形式而产生的。讨论了形态特征和生殖特征，并指出Hommerand的定义必须加以修改，特别是关于原果皮发育的定义。揭示的可能的系统发育系为比较提供了有用的基础，并为该组的分类学提供了一种逻辑方法。文中还讨论了分类中使用的分类学特征和使用该术语的原因。对表明澳大利亚南部物种地理分布的记录的分析几乎没有提供有用的结论。
The southern Australian species of the tribe Crouanieae Schmitz (Ceramiaceae. Rhodophyta) have been studied with particular reference to their taxonomy relationships. and phylogeny; in all cases the type specimens have been examined. Three tribes. Crouanieae. Antithamnieae. and Heterothamnieae. can be recognized. including 16 genera. of which Euptilocladia. Macrothamnion. Tetuathamnion. Amoenothamnion. and Trithamnion are newly described and 48 species (26 newly described) . Recognition of the subfamilies Crouanioideae and Ceramioideae. as defined by Hommersand (1963). is not supported by these studies .Features of greatest taxonomic significance are those indicative also of phylogenetic trends and hence the classification is based upon concepts of phylogeny. Evolutionary advance in both morphological and reproductive features involves specialization, particularly towards adaptations in form with relation to function. The Crouanieae, Antithamnieae, and Heterotharnnieae are probably primitive groups of the Ceramiaceae. The Antithamnieae and Heterothamnieae are closely related and probably arose from the same evolutionary line, while Crouanieae has evolved independently. Thalli in the Heterothamnieae are smaller and less specialized than those of the most advanced species of Antithamnieae, and it is likely that the Heterothamnieae arose as a branch from the Antithamnieae line of development through specialization in reproductive features rather than thallus form. Both morphological and reproductive features are discussed and it is shown that Hommersand's definition of Antithamnieae must be modified, particularly in reference to procarp development. The probable phylogenetic lines revealed form useful bases for comparisons and provide a logical approach to the taxonomy of the group. Taxonomic features used in classification and reasons for the terminology adopted are also discussed. Analyses of records indicating the geographic distribution of species within southern Australia provide few useful conclusions.
