#' Phylogenetic Tree of 133 Plant Species from Pine Forest Flora
#'
#' A phylogenetic tree containing 133 plant species from a pine forest flora study.
#' The tree includes both tip and node labels, is rooted, and contains branch lengths.
#'
#' @format A phylo object (phylogenetic tree) with the following structure:
#' \describe{
#'   \item{tips}{133 terminal nodes representing plant species}
#'   \item{nodes}{121 internal nodes with taxonomic labels}
#'   \item{tip.label}{Species names including Hymenopappus mexicanus,
#'                    Heliomeris multiflora, Bahia dissecta, etc.}
#'   \item{node.label}{Taxonomic group names including Spermatophyta,
#'                     eudicotyledons, Pentapetalae, etc.}
#'   \item{edge.length}{Branch lengths indicating evolutionary distances}
#'   \item{root}{Tree is rooted}
#' }
#'
#' @details
#' This phylogenetic tree represents the evolutionary relationships among 133 plant
#' species found in pine forest ecosystems. The tree structure includes:
#' \itemize{
#'   \item 133 terminal taxa (tip labels with species names)
#'   \item 121 internal nodes with higher-level taxonomic classifications
#'   \item Branch lengths representing evolutionary time or genetic distance
#'   \item Root indicating the common ancestor of all included species
#' }
#'
#' The tree was constructed as part of a comprehensive study examining plant
#' functional strategies in pine forest communities, specifically testing the
#' leaf-height-seed (LHS) plant strategy scheme proposed in functional ecology.
