Question: Are both Ceratophyllum and Eucomis a genus of flowering plants?
Sentence (from "Gnetophyta"): The primary difference between gnetophytes and other gymnosperms is the presence of vessel elements, a system of conduits that transport water within the plant, similar to those found in flowering plants. Because of this, gnetophytes were once thought to be the closest gymnosperm relatives to flowering plants, but more recent molecular studies have largely disproven this hypothesis.
Relevant evidence: No
