A tangle of stems pruned from plants growing out of the top of my tank (see second picture).
This species transitions between emersed and immersed growth without melting issues.
Immersed leaves are thin like Rotala; emersed leaves are shiny and much wider with a pointed tip.
This is a great plant for shallow tanks.

The tank they come from has snails, scuds, duckweed, and hair algae.
