ARTICLE INFO ABSTRACT

Article History: The family is the third largest family in Angiosperms and placed in the in the APG III system of classification. Many plants of this family provide food, fodder, fuel, Received 24th February, 2020 th medicine and other basic needs for the human and animal since the ancient time. This family also Received in revised form 19 play a key role on ecosystem functioning. Point Calimere Wildlife and Birds Sanctuary, March, 2020 encompassing 17.26 km of sandy coast, saline swamps and thorny scrub around the backwaters and Accepted 25th April, 2020 th a resting and migratory route for lakhs of birds, is one of the greatest avian spectacles in the country. Published online 28 May, 2020 The Point Calimere coastal area was declared a Ramsar site (No.1210) and a place of international importance for conservation of biodiversity. The present study is an attempt to document different Key Words: legume and their uses in Point Calimere Wildlife and Birds Sanctuary, Tamil Nadu, . Conservation, Endemics, Exotics, Flora, The present floristic survey recorded 67 species of Fabaceae and covering 26 genera. The Medicinal plants has maximum occurrence with 8 species. The common species of this area, Dalbergia coromandeliana is endemic to Peninsular India. About 48 species have medicinal potential and used to treat many diseases. Geographic landmark and iconic wetland complex of Tamil Nadu, Point Calimere is facing severe ecological pressures including intermittent freshwater flows, hyper salination, degrading health and loss of biodiversity. Government should formulate new policies for the protection and preservation of the biodiversity.

INTRODUCTION Economically, Fabaceae is second in importance only to Poaceae. Leguminosae (Lewis et al., 2005; Yahara et al., The Fabaceae (=Leguminosae A. L. de Jussieu) are of 2013), or Fabaceae (Lewis and Schrire, 2003) is an cosmopolitan distribution. Based on the genus Faba Mill. the economically and ecologically important family. India term Fabaceae was first used by J. Lindley (1836). The new represented by 173 genera 1192 species (Karthikeyan, 2000). classification, Angiosperm Phylogenetic System (APG IV) uses (Fabaceae Lindl.) are one of the largely cultivating made comprehensive phylogenetic analyses of legumes. Based food crops. It provides highly nutritious sources of protein and on the plastid matK gene sequence, long-recognised and widely micronutrients. Significantly it promotes health and accepted subfamilies, DC., livelihoods, particularly in developing countries (Yahara et al., DC., and Papilionoideae DC., are outdated. The separated 2013). Many legumes are improving the fertility by the families of earlier classifications are pooled into a single symbiotic nitrogen fixation (Van den Bosch and Stacey, 2003). family. The total number of plant species described and Legumes products are contribute to world economy though accepted in the APG 2016 is 374,000, of which approximately food, fodder, timber, gums, bio-fuels and medicine. The present 308,312 are vascular plants, with 295,383 flowering plants study is an attempt to document different legume species and (angiosperms; monocots: 74,273; eudicots: 210,008). The their uses in Point Calimere Wildlife and Birds Sanctuary, family Fabaceae consisted of 956 genera 24,505 species (The Tamil Nadu, India. Plant List, 2013); 751 genera, 19,500 species (Maarten and James, 2016); 741 genera, 20200 species (Mabberely, 2017), Study area

770 genera and over 19,500 species (Lewis et al., 2005, 2013; The Point Calimere, the renowned wildlife and bird sanctuary LPWG, 2013). Fabaceae is the third largest angiosperm family on the seashore in Nagapattinam district (Tamil Nadu). It is in terms of species numbers after Asteraceae and Orchidaceae.
