A study was conducted to analyse the phenetic relationship of fifteen species of family Asteraceae found in various parts of Tripura based on their seedling morphological characters and to prepare a synoptic key for their early identification. All taxa showed Phanerocotylar Epigeal Foliaceous (PEF) type of germination, with marked difference in their cotyledonary morphological characters. For preparation of the artificial key various parameters like- germination pattern, position of cotyledon, hypocotyl, epicotyl, and paracotyledon and first two leaves development etc. were considered. The taxonomic status of the studied taxa had been determined on the basis of seedling morphological characters and presented through a phenogram.
