• The most abundant plants were pondweeds ( Potamogeton richardsonii, P . pectinatus ) and coontail ( Ceratophyllum demersum ).
• The main aquatic plants in the lake are " Najas graminea " and " Ceratophyllum demersum ".
• If not enough ceratophyllum or similar vegetation is available, then eggs are scattered out on rocky bottoms in still water.
• It is one of the earliest known flowering plants and has affinities with the modern genus " Ceratophyllum ".
• "Ceratophyllum " grows completely submerged, usually, though not always, floating on the surface, and does not tolerate drought.
• It is believed to only be found in areas vegetated with " Ceratophyllum " and " Najas " at approximately in depth.
• Some analyses make the magnoliids the first to diverge, others the monocots . " Ceratophyllum " seems to group with the eudicots rather than with the monocots.
• The prolific growth of " Ceratophyllum demersum " in the eutrophic zones has been reported, with " Myriophyllum spicatum " and " Potemogetton lucens " cited as dominant species.
