Abstract  The river Rangawali from Navapur of Nandurbar district ( the district Nandurbar formerly known as west Khandesh lies in upper Tapi basin in the North-West corner of Maharashtra) was selected for taxonomical enumeration of algae. Algal samples were collected from five stations of Rangawali river for a period of one year (October 2006- September 2007). In this communication chlorophyceae is studied taxonomically. 27 species belonging to 10 genera were recorded. Genus Scenedesmus was observed dominant. This is first report from this rural area of Khandesh of Maharashtra.  Keywords: Chlorophyceae, Taxonomy, Ragawali river.  INTRODUCTION       The world diversity means variety, diverseness, differences, variations among the individuals in Nandurbar district of Maharashtra .The work on Chlorophyceae is known through Bharate and Tarar (1983), Jyaswal (1993), Ragothamam and Jyaswal (1993), More and Nandan (2005), Nandan (2006). No detail and systematic study of algal flora of River Rangawali from Navapur Taluka. The present investigation deals with taxonomic enumeration of 27 taxa of Chlorophyceae belonging to 10 Genera. In this group genus Senedesmus was observed dominant with many species. This is the first report from this rural area of Kandesh of Maharashtra.  MATERIAL AND METHOD       The algal collection was made at monthly interval from October-2006 to September-2007 from five stations of Rangawali river from Navapur taluka.  The sampling sites were selected carefully, so as to get maximum number of algal forms growing in the varied habitats.  Another important aim of this method of selection is to correlate the species identification to the changes taking place in the habitats sampling was done from 16 km area of Rangawali River. i.e. from five different sites.  Field note-book in maintained in which colour of the algae, habit and habitat were noted down on the spot.  All collections were preserved in 4% formalin for further taxonomical investigation.  Line drawings of different forms of algae were made by camera lucida.  The algae were identified by relevant monographs and recent available literature.    Preparation of Semi-permanent Slides for Green Algae       A drop of glycerin formalin mount ant (6 ml glycerin 10 ml of 40% formaldehyde + 84 ml of distilled water) was taken on slide, to which a drop of concentrated preserved sample was added and was covered by a cover slip of suitable size.
