genus and species concepts in zonaria and homoeostrichus dictyotales phaeophyceae including the description of exallosorus gen nov
European Journal of Phycology, 1997Co-Authors: Julie A PhillipsAbstract:Examination of type material, comparative studies on vegetative characters and data from published accounts of sporangia, gametangia and spermatozoids are used here to further develop and strengthen generic and species concepts in Zonaria and Homoeostrichus. Zonaria is characterized by octosporangia which lack a stalk cell and occur among whitish Paraphyses, by the presence of cortical cells in indusiate sporangial and oogonial sori, and by slightly elongate sterile cells bordering the antheridial sori. Other characters (mucilage in sporangial and oogonial sori, biflagellate sperm with a row of many tall spines along the anterior flagellum) may also be diagnostic of Zonaria but have not been demonstrated in the generitype. Eight species are retained in Zonaria. Generic placement of Zonaria stipitata, described on vegetative characters, requires confirmation. Homoeostrichus, as typified by Homoeostrichus sinclairii, is defined by the presence of brown Paraphyses in nonindusiate sporangial and oogonial sori...

comparative studies on gametangial distribution and structure in species of zonaria and homoeostrichus dictyotales phaeophyceae from australia
European Journal of Phycology, 1997Co-Authors: Julie A Phillips, Margaret N ClaytonAbstract:A comparative study of fertile sporophytes has been carried out on seven dictyotalean species from Australia. Patterns of sporangial distribution and development are similar in Zonaria angustata, Zonaria diesingiana, Zonaria spiralis, Zonaria turneriana and Lobophora variegata but they differ in Homoeostrichus olsenii and Homoeostrichus sinclairii. In Zonaria and Lobophora, sporangia occur in indusiate sori, are embedded in a mucilaginous matrix and, in Z. diesingiana, Z. spiralis and Z. turneriana, are surrounded by whitish Paraphyses. In contrast to Zonaria, the indusiate sporangial sori of H. olsenii form adjacent to concentric rows of brown Paraphyses but they lack both mucilage and Paraphyses. Sporangia of H. sinclairii occur among dense brown Paraphyses which cover the terminal thallus segments. Sporogenesis in species of Zonaria and Lobophora differs conspicuously from other Dictyotalean genera in that nuclear divisions occur when the developing sporangium is quite small, a sporangial stalk cell is...

Comparative morphology and rhizome anatomy of two new species of Zygophlebia (Grammitidaceae) from Madagascar and notes on the generic circumscription of Zygophlebia and Ceradenia
TAXON, 2006Co-Authors: Thierry DeroinAbstract:The recognition of two new Malagasy species of Grammitidaceae, Zygophlebia goodmanii and Z. anjanaharibensis, puts into question some morphological and anatomical features separating the related genera Zygophlebia and Ceradenia, which until now were mainly defined based on neotropical taxa. The two new species share with Zygophlebia and Ceradenia subgen. Filicipecten a rhizome with dorsiventral symmetry and an amphiphloic siphonostele, well-differentiated phyllopodia, a deeply pinnatifid lamina without hydathodes at the tips of veins; and glandular receptacular Paraphyses. Because of the non-waxy translucent exudates of their Paraphyses, the two new taxa are placed in the genus Zygophlebia, in spite of their mostly free leaf veins. Peculiar vascular gaps, unrelated to phyllopodial insertions and distinctive of Zygophlebia, are found in the rhizome stele of Z. goodmanii. The lack of setiform hairs and the distal sori location in Z. anjanaharibensis do not allow for linking this species to any of the three groups previously described by Bishop in Zygophlebia.
