Limnophila brownii

Native only to northern Australia, Limnophila brownii mostly grows emersed on wet ground and only less often in water.²³ It was long included in the variable L. indica until the Australian plants were split off as a species in 1986; it differs in being more strongly hairy and in having longer flower stalks.²

Submersed, the hairy stem, often reddish brown at the nodes, bears whorls of light green pinnate leaves with hair-fine segments, which remain smaller than in similar species; in good light the shoot tips take on a bronze-brown colour.²³ It grows fast when given soft water, strong light, plenty of CO₂ and good fertilisation; in moderately hard water with poor fertilisation it becomes leggy and forms only small whorls.²³ Planted in groups it shows to good effect in the midground to background; it is propagated by top cuttings and occasionally by creeping runner-like shoots.³
