Sphenophyllum
Also called Tracheophytes
Sphenophyllum is an extinct genus of Paleozoic plants, known only from fossils, not a plant you can grow. Its members were small, whorled-leaved relatives of horsetails, so care advice does not apply.
Sphenophyllum is a genus in the order Sphenophyllales. It has been placed in the family Sphenophyllaceae.
