“…also occur in this plateau. Recently, a number of new species were described from similar lateritic habitats of northern Kerala (Image 4 & 5) and plateaus of the Konkan region (Ansari et al 1982;Bhat & Nagendran 1983;Nair et al 1983;Yadav & Janarthanam 1994;Raju 1985;Potdar et al 2004;Gad & Janarthanam 2007;Raj & Sivadasan 2008;Yadav et al 2008Yadav et al , 2010Malpure & Yadav 2009;Prabhugaonkar et al 2009;Shimpale & Yadav 2010;Nandikar & Gurav 2011;Kambale et al 2012;Potdar & Yadav 2012;Prasad & Raveendran 2013a&b;Prasad et al 2012;Shahina & Nampy 2014;Gaikwad et al 2014;Biju et al 2016a,b,c;Darshetkar et al 2017;Bokil et al 2020).

Rotala sahyadricasp. nov. (Lythraceae) from Western Ghats, India

“…Th e genus Rotala L. was earlier represented by ca 44 species, distributed mostly in tropical and subtropical regions of the world (Cook 1979, 1996, Mabberley 2008. After Cook ' s revision in 1979, 11 species have been added to the genus by various workers (Lu 1979, Joseph and Sivarajan 1988, 1989, Bamps 1989, Beesley 1990, Mathew and Lakshminarasimhan 1990, Pradeep et al 1990, Yadav et al 2010, Prasad et al 2012, Sunil et al 2013, Prasad and Raveendran 2013. However, Almeida (1998) reduced one species to the rank of variety.…”
