According to recent molecular phylogenetic data, the rare Australian endemic Maundia triglochinoides does not form a clade with taxa traditionally classified as members of Juncaginaceae. Therefore, views on the morphological evolution and taxonomy of Alismatales require re-assessment. As the morphology of Maundia is poorly known and some key features have been controversially described in the literature, the flowers, fruits, inflorescence axes and peduncles were studied using light and scanning electron microscopy. Inflorescences are bractless spikes with flowers arranged in trimerous whorls. Except in the inflorescence tip (where the flower groundplan is variable), flowers possess two tepals in transversal-abaxial positions, six stamens in two trimerous whorls and four carpels in median and transversal positions. Fruits are indehiscent. The shared possession of orthotropous ovules supports the molecular phylogenetic placement of Maundia as sister to a large clade including Potamogetonaceae and related families. Maundia and Aponogeton spp. share the same highly unusual floral groundplan, a homoplastic similarity that can be explained by spatial constraints in developing inflorescences. The nucellar coenocyte of Maundia appears to be unique among monocots. As Maundia exhibits a mosaic of features characteristic of other families of tepaloid core Alismatales, its segregation as a separate family is plausible.

Although a fairly recent monograph has been published, the genus remains poorly studied systematically. We conducted a phylogenetic survey of Aponogeton that focuses on relationships among the nine native Australian species as well as their relationship to other members of the genus. Our analyses included a phylogenetic assessment of morphological characters and molecular data obtained both from chloroplast (trnK 5{\textquoteright} intron, matK) and nuclear DNA (nrITS) loci. Molecular data provided evidence of hybridization and polyploidy as well as an informative overview of interspecific relationships in the genus. Two potentially new Australian species alwo were identified by the molecular data. Combined molecular data produced a well-resolved cladogram that enabled us to evaluate previous phylogenetic hypotheses based on non-explicit methods as well as teh soundness of the existing classification of the genus. We conclude that Aponogetonaceae originated in Australia and subsequently radiated into Africa, Madagascar, and Asia, from which a secondary Australian diversification occurred resulting in a biphyletic origin of the native Australian species. A pattern of morphological distinctiveness coupled with low molecular divergence indicates relatively recent and rapid speciation of Aponogeton in Australia. Our results also demonstrate that in this group, morphological data are extremely unreliable taxonomically due to their extensive homoplasy. The phylogenetic relationships elucidated by this study provide evidence to support the establishment of two additional sections, Flavida and Viridis, which are described.}, author = {Les, Donald H. and Moody, Michael L. and Jacobs, Surrey W.L.} } @article {208, title = {Systematics of Seagrasses (Zosteraceae) in Australia and New Zealand}, journal = {Systematic BotanySystematic Botany}, volume = {27}, number = {3}, year = {2002}, note = {evtl. interessantes paper zitiert (Bayer 1999) zur Evolution polyploider KomplexeCTAB-Methode (Rogstad 1992)}, pages = {468-484}, keywords = {systematics, taxonomy, ITS, trnK intron, rbcL, Zosteraceae, seagrasses, Australia, New Zealand}, author = {Les, Donald H. and Moody, Michael L. and Jacobs, Surrey W.L. and Bayer, Randall J.} } @article {172, title = {A biogeographical analysis of the freshwater plants of Australasia}, journal = {Australian Systematic BotanyAustralian Systematic Botany}, volume = {9}, year = {1996}, pages = {169-183}, author = {Jacobs, Surrey W.L. and Wilson, Karen L.} }
