''Ulva paschima''is a green alga in the division Chlorophyta, a green seaweed endemic to the West Coast of India. The species was identified in 2014 based on molecular phylogenetics using ITS sequences as belonging to the “Paschima” clade.〔Bast F, John AA, Bhushan S (2014) Strong Endemism of Bloom-Forming Tubular ''Ulva'' in Indian West Coast, with Description of ''Ulva paschima'' Sp. Nov. (Ulvales, Chlorophyta). PLoS ONE 9(10): e109295. doi:10.1371/journal.pone.0109295〕 ==Description== The fronds are erect, filamentous, and grass-green in color, 5 cm-40 cm in length, mostly unbranched, tubular, with some parts of the thalli compressed like flat ribbons. The tufts of filamentous thalli are attached to the substrate by rhizoids. Thalli from low-saline environments are branched, while that exposed to the ocean are non-branched. Cells are more or less quadrilateral; some have linear cell arrangement. Parietal chloroplasts have more than two pyrenoids per cell.
