P. M. Catling
Lakes and rivers, in water up to 4.6 m deep, though mostly shallower.
There is a rather frequent tendency for some of the leaves to be alternate in this species, so that vegetative fragments may resemble M. farwellii. This is a variable species in other respects as well. Stranded plants on moist shores may produce deeply serrate (or shallowly pectinate) “terrestrial” leaves or bracts; the tips of these or other aerial shoots if they become inundated may again produce typical dissected leaves.
The very short internodes and often more than 4 leaves at a node give this plant a very dense appearance; the long shoots look like green ropes under the water.
