hornwort
Non-vascular land plant
Hornwort refers to two unrelated types of plants.
One is a group of small, ancient land plants related to mosses, named for their horn-shaped spore capsules.
The other is an aquatic plant commonly kept in freshwater aquariums, where it floats freely or anchors loosely to substrate: Hornwort helps keep the tank water clear.
