General Description

Fronds. Fronds 1-4 mm long, 0.8-3.5 mm wide, mostly 1-1 1/2 times as long as wide (the relatively roundish shape is restricted to certain environmental conditions especially under limiting phosphate concentrations, a situation which is very often found in nature cf. DOCAUER 1984); somewhat shiny on the upper surface; rather distinct papules along the nerves (the papule near the tip usually not larger than the other papules); 3 nerves; rarely gibbous (up to 2 mm thick); sometimes with red spots on the upper surface (especially near the tip); often red pigmentation on the lower surface (always more intensely red than on the upper surface), the pigmentation beginning around the node; greatest distance between the lateral nerves in or slightly above the middle of the nerves; largest air spaces rarely wider than 0.3 mm; rootcap mostly rounded, sometimes pointed (living material), rounded or pointed (dried material); occasionally (especially at the end of the vegetation period) rootless, small, olive to brown coloured turions present, which sink to the bottom of the water and stay there for the cold season.


Flowers and fruits: Plants occasionally flowering and rarely fruiting. Ovary with 1 ovule; style 0.15-0.20 mm long; fruit 0.5-0.6 mm long; 0.6- 0.8 mm wide, without winged margin; seed 0.5-0.8 mm long, about 0.5 mm thick, whitish, with 30-60 indistinct ribs, stays within the fruit wall after ripening.
