Published online by Cambridge University Press: 11 June 2012
Synopsis
Two series of logarithmic expansion systems are described, with × 1·6 as the rate of increase in numbers of new monotypic genera correlated with a rate of × 2·0 for increase in total numbers of species. These series are discussed in relation to current numbers for monotypic genera, total genera, and total species in 36 of the largest 45 families of flowering plants.
