Chiastocaulon conjugatum is excluded from the Australian flora, because previous Australian records are based on misidentifications of C. Pedinophyllum monoicum, reported for Australia from a single locality in Victoria, is excluded from the Australian flora because all credible records are based on misidentifications of Syzygiella tasmanica.

The biomolecular data used for such calculations are usually nucleotide sequences for DNA or amino acid sequences for proteins.This complexity poses many challenges that limit modern scientific investigations from truly leveraging the genome revolution.First, the application of the fastest molecular dating tools available already requires a very large amount of computational time for datasets containing only a few hundred sequences, which are modest for today’s standards (6, 7).The method (Rel Time) performed better than existing methods when applied to very large computer simulated datasets where evolutionary rates were varied extensively among lineages by following autocorrelated and uncorrelated models.On average, Rel Time completed calculations 1,000 times faster than the fastest Bayesian method, with even greater speed difference for larger number of sequences.We examined whether: i) strict clock models are generally more appropriate in shallow phylogenies where rate variation is expected to be low, ii) the likelihood ratio test of the clock (LRT) reliably informs which model is appropriate for dating divergence times.
