Contents
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.
Distribution
The distribution is endemic to Indian West Coast.
Ecology
The species is found in intertidal rocks of saline and estuarine environments with various seawater salinities (35 to 24 PSU).
Life history
The sporangial and gametangial thalli are morphologically alike. The diploid adult plant produces haploid zoospores by meiosis; these settle and grow to form haploid male and female plants similar to the diploid plants. When these haploid plants release gametes they unite to produce the zygote which germinates, and grows to produce the diploid plant.
