Question: Are Sparaxis and Salvinia both types of plant?
Sentence (from "Salvinia"): The genus was published in 1754 by Jean-François Séguier, in his description of the plants found round Verona, "Plantae Veronenses" Twelve species are recognized, at least three of which ("S. molesta", "S. herzogii", and "S. minima") are believed to be hybrids, in part because their sporangia are found to be empty.
Relevant evidence: No
