Lake Watershroom
Evolved from B. bulbus they developed to be larger to absorb more sunlight by increasing surface area and started to grow in the shallow tidal areas to avoid competition with M. aquariusa. To adapt to this they store water in their stem and bulb with thicker cell walls to retain water in order to stay moist when it gets exposed to atmospheric air.
Found in very tidal areas of zone 21 they grow up to 12cm tall with a diameter of 14cm. They store water in their bulb or stem so that when the shoreline drains out they can still survive while being unsubmerged. They live in depths of 0-2m.
They reproduce by releasing spores in the water letting spores flow through water until they reach the substrate and grow.
