Question: Does the genus Euptelea contain more species than the genus Ceratophyllum?

Context paragraphs:
Gastornis: Gastornis is an extinct genus of large flightless birds that lived during the late Paleocene and Eocene epochs of the Cenozoic era.  The genus is currently thought to contain three or four distinct species, known from incomplete fossil remains, found in western-central Europe (England, Belgium, France and Germany).  More complete specimens are known from a fourth, North American species, which had previously been classified in the distinct genus Diatryma.  Many scientists now consider "Diatryma" to be so similar to the other species of "Gastornis" that it should also be included in that genus.  A fifth species, also previously classified in its own genus, is known from China.

Xylothamia: Xylothamia, the desert goldenrods, is a genus of flowering plants in the daisy family, Asteraceae.  Until 2003, it was held to contain nine species of shrubs native to deserts of Mexico and the southwestern United States.  However, it seems to contain at least two groups.  Four species are related to "Gundlachia" and may be moved to that genus.  The relationships of the other five species is not quite as clear.  All nine species do belong in the subtribe Solidagininae.

Euphronia: Euphronia is a genus of three species of shrubs native to northern South America and is the only genus in the family Euphroniaceae.  It was previously classified in the Vochysiaceae family and elsewhere, but the APG III system of 2009 recognizes Euphroniaceae and places "Euphronia" in it.  The genus was originally described by Carl Friedrich Philipp von Martius and Joseph Gerhard Zuccarini in 1824 when they described "Euphronia hirtelloides" as a new species.  In 1918, the German botanist Johannes Gottfried Hallier reclassified what was then known as "Lightia guianensis" as a species in this genus: "Euphronia guianensis".  And in 1987, the American botanist Julian Alfred Steyermark described the third species, "Euphronia acuminatissima".  It was proposed in 1989 that the family Euphroniaceae be erected to contain the genus because it was sufficiently different from other related genera.  An analysis of the molecular phylogenetics of these related genera and families in 1998 supported the decision to retain the genus within a monotypic family.

Montsechia: Montsechia is an extinct genus of aquatic plants containing the species Montsechia vidalii, discovered in Spain.  "Montsechia vidalii" lived about 130 million years ago, during the Barremian age, and appears to be the earliest known flowering plant.  It has affinities with the modern genus "Ceratophyllum".

Euptelea: Euptelea is a genus of two species of flowering plants in the monogeneric family Eupteleaceae.  The genus is found from Assam east through China to Japan, and consists of shrubs or small trees:

Porpolomopsis: Porpolomopsis is a genus of fungi in the family Hygrophoraceae.  It was circumscribed in 2008 by Andreas Bresinsky to contain "P. calyptriformis".  Bresinsky separated it from the genus "Hygrocybe" based on its color and the absence of DOPA pigments. " P. lewelliniae" was transferred to the genus based on DNA and morphology.  Three undescribed species also belong in the genus.  Species of "Porpolomopsis" have also formerly been placed in the genus "Humidicutis", to which they are closely related but differ in having narrowly attached or free gills and the shape of the hyphae in their cap.  Species of "Porpolomopsis" are found in Europe, North America, Asia, Australia and New Zealand.

Verticillium: Verticillium is a genus of fungi in the division Ascomycota, and are an anamorphic form of the family Plectosphaerellaceae.  The genus used to include diverse groups comprising saprobes and parasites of higher plants, insects, nematodes, mollusc eggs, and other fungi, thus the genus used to have a wide-ranging group of taxa characterised by simple but ill-defined characters.  The genus, currently thought to contain 51 species, may be broadly divided into three ecologically based groups - mycopathogens, entomopathogens, and plant pathogens and related saprotrophs.  However, the genus has undergone recent revision into which most entomopathogenic and mycopathogenic isolates fall into a new group called Lecanicillium.  The genus now includes the plant-pathogenic species "V. dahliae", "V. longisporum", "V. albo-atrum", "V. nubilum", and "V. tricorpus".

Ceratophyllum echinatum: Ceratophyllum echinatum, commonly called spineless hornwort, is an aquatic perennial plant of the genus Ceratophyllum.  It can be found in ponds and lakes.  It is principally an eastern North American species and the only species of its genus endemic to North America.

Bolitoglossa: Bolitoglossa is a genus of lungless salamanders, also called mushroom-tongued salamanders tropical climbing salamanders or web-footed salamanders, in the family Plethodontidae.  Their range is between northern Mexico through Central America to Colombia, Venezuela, Ecuador, Peru, northeastern Brazil, and central Bolivia.  Neotropical salamanders of the "Bolitoglossa" genus make up the largest genus in the order Caudata, consisting of approximately one-fifth of all known species of salamanders.  Adult salamanders range anywhere from 45mm to 200mm in length depending on their specific species.  They are notorious for their ability to project their tongue at prey items, as indicated from their name.  They are also known for their webbed feet, having significantly more webbing than any other species outside their genus with the exception of the cave-dwelling Mexican bolitoglossine "Chiropterotriton magnipes".  Although webbed feet are a common characteristic of these salamanders, only about half of the species in this genus contain webbed feet.

Ceratophyllum: Ceratophyllum is a cosmopolitan genus of flowering plants including four accepted species in 2016, commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions.  It is the only genus in the family Ceratophyllaceae, itself the only family in the order Ceratophyllales.  They are usually called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
