A most rare, pond-dwelling plant. I've heard tell of its throbbing blood-red bulb from wizards who journeyed in the Far East!
-- Zygmunt Budge
A rare magical water plant from the Far East with a throbbing red bulb.
Used to make the Potion of All Potential.
ganglion = Presumably because the throbbing reb bulb resembles a ganglion cyst
