Aims of TAXONOMY

Aims of SYSTEMATICS

  • the art and science of finding evolutionary relationships between living organisms
  • To construct a meaningful Tree of life

STATUS of FLOWERING PLANTS 

Angiosperm File: According to APG classification (1998-I, 2003-II, 2009-III, 2016-IV)Class Magnoliopsida (Angiosperms or flowering plants) come under 8 (5 orders & 3 clades) groups : Amborellales (1 family /1 genus / 1 sp. ~ Amborella trichopoda, the most primitive angiosperm); Nymphaeales (3 family / 9 genera / ca. 80 spp.); Austrobaileyales (3 family / 5 genera / ca. 100 spp.); Chloranthales (1 family / 4 genera / ca. 70 spp.); clade magnoliids (4 orders/ ca. 9,000 spp.); clade monocots (11 orders/ ca. 70,000 spp.); Ceratophyllales (1 family / 1 genus / 6 spp.); clade eudicots (40 orders/ ca.1,75,000 spp.)
