ABSTRACT:

Plant taxonomy is a branch of botany that deals with identification, classification and nomenclature of plants. All the four genus discussed in this paper belong to subfamily Faboideae according to the APG IV classification. Most taxonomic keys that are available for Family Fabaceae Lindl. are based on floral characters for which plants will have to be in their reproductive phase. Flowering phase for most members of the concerned family lasts for a maximum of four months, therefore the plant is mostly found in its vegetative phase and lack of a taxonomic key solely based on vegetative characters can delay the identification process. The solution to this could be achieved by developing a valid taxonomic key using leaf morphological characters. Studies incorporating the varied and unique architecture of each leaf or leaflet may prove to be an important breakthrough to help identify plants in any season and help pace up the related research works. These can also provide adequate information in paleobotanical fields concerning fossils discovered in the form of leaves. Comparision of tree constructed based on the cladistics with the molecular key may help validate the results
