Phylogenetic analysis of Eucalyptus subgenus Eudesmia is presented on the basis of the following three datasets: sequences of the internal transcribed spacer (ITS) and the external transcribed spacer (ETS) regions from nuclear rDNA, sequences of the psb A– trn H intergenic spacer region from...
We present evidence that fossil leaves from an early Eocene estuarine mudstone deposit at Lowana Road in western Tasmania include the oldest records of the extant monocot genus, Ripogonum (Ripogonaceae). These fossils are similar to the extant eastern Australian and Papua New Guinean R. album...
Three new rare taxa allied to the conspicuous, common four-winged mallee ( Eucalyptus tetraptera Turcz.) are described. E. sweedmaniana is a large-leaved and prostrate coastal mallee known only from Mount Arid, Western Australia. E. brandiana , a non-lignotuberous mallet, occupies spongolite...
The genus Nitella Ag. in algal family Characeae is characterised by furcate (forked) branchlets, compressed oospores (i.e. oval in cross-section), terminal antheridia and a 10-celled coronula on the oogonium. Species of Nitella are submerged plants that grow in a variety of wetland and riverine...
Phylogenetic analyses of nuclear DNA external transcribed spacer (ETS) and chloroplast DNA trn L– trn F markers were undertaken to reconstruct the evolutionary history of the South Pacific genus Melicytus . Bayesian analyses of the ETS sequence data produced a phylogenetic tree with several well...
