Although temporal calibration is widely recognized as critical for obtaining accurate divergence-time estimates using molecular dating methods, few studies have evaluated the variation resulting from different calibration strategies. Depending on the information available, researchers have often used primary calibrations from the fossil record or secondary(More)
We present a phylogenetic analysis and comparison of structural features of chloroplast genomes for 39 species of the eucalypt group (genera Eucalyptus, Corymbia, Angophora, and outgroups Allosyncarpia and Stockwellia). We use 41 complete chloroplast genome sequences, adding 39 finished-quality chloroplast genomes to two previously published genomes.(More)
Sequences of the 5S rDNA repeat have been determined from four outgroup taxa (Arillastrum group), 2 Angophora species, and 19 Eucalyptus species (including representatives from all informal subgenera). Alignment shows that, as in other plants, the tandemly repeated 5S rRNA genes are highly conserved while the noncoding intergenic spacers are variable. A(More)
Section Vireya (Blume) Copel.f. is one of the most morphologically diverse groups of the genus Rhododendron. Vireyas have a unique distribution for the genus, being predominantly found throughout the Malesian Archipelago. The alpha taxonomy of section Vireya is relatively well understood and taxa are easily distinguished from other rhododendrons by their(More)
Parsimony analyses of the internal transcribed spacer regions of nuclear ribosomal DNA (ITS 1 & ITS 2) for 38 taxa sampled from the Phebalium group (Rutaceae: Boronieae) and two outgroups confirm that, with the exception of Phebalium sensu stricto and Rhadinothamnus, six of the currently recognised genera within the group are monophyletic. The data indicate(More)
A new sequestrate fungus, Barcheria willisiana gen. et sp. nov., is described and its affinities evaluated using nLSU rDNA sequence data. This unusual fungus has several characters that are reminiscent of species of Agaricus and Lepiota, but with a very reduced basidiome form. The nLSU rDNA of four Australian taxa, Barcheria willisiana, Agaricus(More)
The 2003 conference of the Australian Systematic Botany Society was held at The University of Melbourne to commemorate the 150 anniversary of the founding of the National Herbarium of Victoria (MEL). The Herbarium was founded following the appointment, on 26 January 1853, of Ferdinand Mueller as the first Government Botanist of Victoria by(More)
The decision at last year’s International Botanical Congress to allow the use of either Latin or English for botanical descriptions and diagnoses was hailed as a triumph by the community. The ruling came into effect from 1 January 2012, but many botanists persist in using Latin. There may be an element of understandable cultural resistance to changing to(More)
