Context :

• Recently , Sheathia rosemalayensis was a newly discovered species of freshwater algae.
• The species was identified in Rosemala. It is situated in Kollam district of Kerala. It is a part of the Western Ghats.
• The name "rosemalayensis" is derived from its place of discovery Rosemala.

Significance of the Discovery

• The Sheathia genus is extremely rare in India.
• Prior to this there was only one other species (S. assamica). Which was documented from the Himalayas.
• Sheathia rosemalayensis is geographically isolated & it is found only in the southern Western Ghats of Kerala.
• Other species in the Sheathia genus like assamica, S. indonepalensis, S. dispersa have broader distribution including Assam, Nepal, Indonesia, Taiwan, & Hawaiian Archipelago.

About Algae

• Algae are microscopic organisms that use sunlight to produce energy through photosynthesis.
• They can be unicellular or multicellular.
• They are found in fresh, salt, & brackish water.

Characteristics

• Algae lack a well defined body so they don't have roots, stems, or leaves like plants
• They can reproduce asexually by forming spores or sexually.
• Some algae form symbiotic relationships with other organisms.
• A few types of algae produce toxins.

Types of algae

• Brown algae are a large group of multicellular algae that includes many seaweeds. They are found in colder waters in the Northern Hemisphere.
• Red algae are a large group of algae that includes many seaweeds. They are a primary source of cellular carbon & chemical energy for other organisms.
• Diatoms are a major group of microalgae that are found in oceans, waterways & soils. They have a unique cell wall made of silica.
• Euglenoid algae are a genus of algae that includes many species. Blooms form a surface scum that may vary in color.
• Golden algae are a small group of microalgae that are mainly freshwater algae.
• Green algae are a type of algae that is found in freshwater environments. They can be used for food, biofuel, & other purposes.

Conclusion

The discovery of Cyathea rosmalensis adds an important new chapter to the study of freshwater algae within India's rich biodiversity hotspot the Western Ghats. The discovery highlights the ecological importance of the region and the potential for further discoveries in the unique ecosystem of the Western Ghats.
