Question: Which has more species Nothoscordum or Calypso bulbosa?

Context paragraphs:
Nothoscordum: Nothoscordum is a genus of New World plants in the onion tribe within the Amaryllis family.  It is probably paraphyletic.  The genus is native to North and South America, though a few species have become naturalized in various parts of the Old World.

Drosera bulbosa: Drosera bulbosa, the red-leaved sundew, is a perennial tuberous species in the genus "Drosera" that is endemic to Western Australia.  It grows in a rosette and produces white flowers emerge from April to June.  "D. bulbosa" was first formally described by William Jackson Hooker in 1841.

Pepinia bulbosa: Pepinia bulbosa is a species in the genus "Pepinia".  It was originally described by Lyman Bradford Smith in 1955 as "Pitcairnia bulbosa" and later moved to the genus "Pepinia" by Ganapathy Subramaniam Varadarajan and Amy Jean Gilmartin in 1988.

Erigenia: Erigenia bulbosa, also known as harbinger of spring or pepper and salt, is a perennial plant in the carrot family (Apiaceae).  "E. bulbosa" is the only species in the genus Erigenia (Nutt. ).  This plant is known as harbinger of spring because it is one of the earliest blooming native wildflowers of rich forests in the mid-latitude United States.  It is found as far north as central New York and southern Wisconsin, west to the western Ozarks, and south to central Alabama.  It is also found in extreme southern Ontario. Throughout most of its range it blooms from late February through early April.  It is a small spring ephemeral reaching only 5–15 cm tall when in flower, and slightly larger afterwards.  Each spherical bulb gives rise to a single purplish stem, which terminates in an umbel.  The flowers have white petals and large dark-reddish anthers.  The teardrop shaped petals are 3-4 millimeters long, widely spaced and do not touch each other.  As is characteristic of the carrot family, the leaves of this plant are sheathed at the base and pinnately divided into many small sections.

Poa bulbosa: Poa bulbosa is a species of grass known by the common names bulbous bluegrass or bulbous meadow-grass.  It is native to Eurasia and North Africa, but it is present practically worldwide as an introduced species.  It is widespread in the United States and southern Canada.  It was introduced to the eastern United States around 1906 and the western US in 1915 as a contaminant in shipments of alfalfa seed.  It was intentionally planted on both the east and west coasts to control weeds and prevent erosion.  Today it is a common grass across the continent and is a noxious weed in some areas.  It is a sturdy, hardy, persistent, aggressive grass that easily outcompetes many other plants and becomes the dominant species in disturbed habitat types, such as overgrazed fields.

Drosera browniana: Drosera browniana is a perennial tuberous species in the genus "Drosera" that is endemic to Western Australia.  It grows in a rosette about 3 to 4 cm in diameter.  It is a common species in an area from Mount Holland to Hatters Hill along the greenstone belt northwest of Esperance.  It grows in loam soils in wet zones near granite outcrops.  It flowers from August to September.  It is considered to be related to "D. bulbosa".  It was first formally described by Allen Lowrie and N. G. Marchant in 1992 and named in honour of Andrew Brown, who discovered this species' first population.

Belenois calypso: Belenois calypso, the Calypso white or Calypso caper white, is a butterfly in the Pieridae family.  It is found in Senegal, the Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Burkina Faso, Ghana, Togo, Benin, Nigeria, Cameroon, the Republic of the Congo, the Central African Republic, the Democratic Republic of the Congo, Angola, Uganda, Kenya and Tanzania.  The habitat consists of forests.  The species occasionally migrates.

Armillaria gallica: Armillaria gallica (synonymous with "A. bulbosa" and "A. lutea") is a species of honey mushroom in the Physalacriaceae family of the Agaricales order.  The species is a common and ecologically important wood-decay fungus that can live as a saprobe, or as an opportunistic parasite in weakened tree hosts to cause root or butt rot.  It is found in temperate regions of Asia, North America, and Europe.  The species forms fruit bodies singly or in groups in soil or rotting wood.  The fungus has been inadvertently introduced to South Africa.  "Armillaria gallica" has had a confusing taxonomy, due in part to historical difficulties encountered in distinguishing between similar "Armillaria" species.  The fungus received international attention in the early 1990s when an individual colony living in a Michigan forest was reported to cover an area of 15 ha , weigh at least 9500 kg , and be 1,500 years old.  This individual is popularly known as the "humungous fungus", and is a tourist attraction and inspiration for an annual mushroom-themed festival in Crystal Falls.

Calypso bulbosa: Calypso is a genus of orchids containing one species, Calypso bulbosa, known as the calypso orchid, fairy slipper or Venus's slipper.  It is a perennial member of the orchid family found in undisturbed northern and montane forests.  It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard.  The genus "Calypso" takes its name from the Greek signifying concealment, as they tend to favor sheltered areas on conifer forest floors.  The specific epithet, "bulbosa", refers to the bulb-like corms.

Belemnitella bulbosa: Belemnitella bulbosa is a species of belemnite from the Late Cretaceous of North America.  It is known only from two localities - the Pierre Shale and Fox Hills Formations. "B. bulbosa" had a slender somewhat cylindrical rostrum (guard) with a slightly expanded front opening.  Like other members of the genus "Belemnitella", it had a dorsal ridge on the rostrum.  The phragmocone is about the same size or slightly longer than the rostrum and has an oval cross-section.
