[email protected] Abstract Freshwater green alga of Raja-Rani wetland has been studied. A total 36 algal samples were collected from 12 sites by squeezing the submerged aquatic plants. Present paper describes 35 green algae under 18 genera from Raja-Rani wetland as new record for Nepal.Genus Euastrum consists 5 species; genera Cosmarium, Staurodesmus, and Staurastrum consist 4 species each; genera Scenedesmus, Closterium, Pleurotaeniuum and Xanthidium consist 2 species each; and rest genera consist only single taxa each. Water parameters of the wetland of winter, summer and rainy seasons were also recorded. Keywords: Chlorophyceae, Cosmarium, New report, Staurodesmus, Triploceras,Xanthidium Introduction climatic condition and rich aquatic habitats for algae, extensive exploration is lacking in the history.Suxena Algae are the simplest photosynthetic thalloid plants, & Venkateswarlu (1968), Hickel (1973), Joshi usually inhabited in water and moist environment (1979), Subba Raju & Suxena (1979), Shrestha & throughout the world. Green algae are the largest Manandhar (1983), Hirano (1984), Ishida (1986), and most diverse group of algae, with about 8000 Watanabe & Komarek (1988), Haga & Legahri species known (Guiry, 2012). They have wide range (1993), Watanabe (1995), Baral (1996, 1999), Das of habitats as they grow in freshwater, marine, & Verma (1996), Prasad (1996), Komarek & subaerial, terrestrial, epiphytic, endophytic, parasitic, Watanabe (1998), Simkhada et al.
