branches emerge in such great number that dense tufts arise. The 

 colour is dark-green sometimes with a reddish tinge. This species 

 has only been found on these marsh-liite localities in Krausse's 

 lagoon, whereas the species yet to be mentioned can also occur in 

 other halophyte formations. 



Of other species occurring in sucti localities Batis maritima L.

is the most common ; it has long, prostrate, rooting main branches 

 often almost straight as a line, from which at each internode two 

 opposite branches, the one more vigorous than the other, emerge
