My idea of Carnivorous Water Plants which will form a symbiosis with Acrodontium crateriforme in order to digest Insects. Though it's ancestors will be Terrestrial Mycoheterotrophs, with selective breeding and possible Gamma Radiation I can easily overcome this!

Thinking about putting hybrid seeds of Allotropa virgata & Hemitomes congestum in a tank of Acrodontium crateriforme (Helps Carnivorous Plants digest Insects) along with Water Insects. Hopefully some embryos survive and form a Mycorhizal association with the Fungus, resulting in a lineage of Aquatic Carnivorous Monotropes losing their Cell Walls after several generations, an Animal-Like Strain might develop similar to Triffids.
