A study on phylogeny of phyllanthaceae using morphological features

Author(s): Vanlalhruaia, J Lalbiaknunga
Abstract: The Phyllanthaceae family of plant contains around 6000 species in 59 accepted genera. It is one of the five subfamilies of Euphorbiaceae sensu lato and is now a family on its own after the latter is split into five family. The family is represented by herb, shrubs and trees. Mesquite software running Zephyr package to use PAUP algorithm is used to describe the species relationship and morphological phylogeny. 31 contrasting binary character states that can be used to define the individual species were selected and the matrix from 30 collected taxa were analysed by random taxon addition followed by a tree bisection reconnection, all the characters are unweighted and are unordered. Furthermore, jackknife-analysis with 50 replicates of the characters were also performed. The analysis results a tree with consistency index of 0.39 and a retention index of 0.79 with tree length of 76 steps. The analysis shows the two tribes Antidesmatoideae and Phyllanthoideae in different clade. The resultant trees show support for various subfamily and tribe while there are some contrasting results.
