#' Leaf longevity and leaf mass per area for plant species from different sites
#' 
#' @description This dataset contains the leaf longevity and leaf mass per area of 75 plant
#' species from four sites in south-eastern Australia. Sites represent
#' contrasts along rainfall and soil phosphorous gradients.
