Morphology/Character
 
Biology
This is an eurybiontic species. Its growth habit makes it a good substratum stabilizer and sediment accumulator. The leaf size varies with the substratum, being broader (up to 3.5 mm wide) in sheltered muddy areas and narrower (1mm wide) in exposed sandy shores. In Port Dickson, the average standing biomass was as 1.09g dry wt. m-2 in 1994. [1]
