The included species are characterized by uncalcified thalli with a medulla composed of a limited number of interwoven siphons that form a cortex of distinctive utricles toward the periphery. Detailed morphological descriptions are provided for all known species. A combination of characters relating to general habit, morphology of the axes, apices and utricles distinguishes all species easily. Re-examination of Indonesian and Papua New Guinean specimens, previously reported as <i>Pseudocodium floridanum</i>, reveals that they belong to the recently described <i>Pseudocodium okinawense</i>. South African specimens formerly attributed to <i>P. floridanum</i> are described as a new species, <i>Pseudocodium. natalense. Pseudocodium australasicum</i>, a species endemic to southern Australia, does not fit the generic concept of <i>Pseudocodium</i> in that it does not possess a cortex composed of utricles. Putative reproductive structures have thus far only been reported for <i>P. floridanum</i>. Observations on <i>Pseudocodium devriesii</i> and <i>P. natalense</i> reveal very similar spherical to irregular structures formed laterally on medullary siphons in the axils of peripheral utricles. Interestingly, and confirming the earlier observations of Dawes & Mathieson, no basal cross wall is formed at the base of the reproductive structures. Instead, a translucent plug at the base of the reproductive structures prevents the cytoplasm from leaking. This suggests that <i>Pseudocodium</i> is not holocarpic, unlike most Halimedineae. DNA sequences of <i>rbc</i>L and <i>tuf</i>A are presented for all species and the resulting phylogenies are used as a framework to study the evolution of morphological features as well as the biogeography of the genus, both at the global scale and within the Indian Ocean.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Systematics and biogeography of the genus <i>Pseudocodium</i> (Bryopsidales, Chlorophyta), including the description of <i>P. natalense</i> sp. nov. from South Africa","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Bryopsidales; Biogeography; Indian Ocean; Pseudocodium; rbcL; Systematics; Phylogeny; tufA","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2012-02-16","DateCreate":"2011-10-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000254074400009","VABBcode":null,"OpenAcc":0,"DOI":"10.2216/07-79.1"},"refs":null,"anarec":{"AnaID":208644,"PubliDate":2008,"Pagination":"225-235","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43657,"SerRR":"Phycologia.
