Question: Are both Strombocactus and Calypso bulbosa both genus of plants ?

full_context: Document 1: Cypripedium candidum: Cypripedium candidum, also known as small white lady's slipper or white lady's slipper, is a rare orchid of the "Cypripedium" genus.
Document 2: Paphiopedilum: Paphiopedilum, often called the Venus slipper, is a genus of the Lady slipper orchid subfamily "Cypripedioideae" of the flowering plant family Orchidaceae. The genus comprises some 80 accepted taxa including several natural hybrids. The genus is native to Southeast Asia, the Indian Subcontinent, southern China, New Guinea and the Solomon and Bismarck Islands.
Document 3: Coryphantha: Coryphantha (from Greek, "flowering on the top"), or beehive cactus, is a genus of small to middle-sized, globose or columnar cacti. The genus is native to arid parts of Central America, Mexico, through Arizona, New Mexico, and western Texas and north into southwestern, central, and southeastern Montana. With its two subgenera, 57 species and 20 subspecies, it is one of the largest genera of cactus.
Document 4: Escobaria sneedii: Escobaria sneedii (syn. "Coryphantha sneedii") is a rare species of cactus known by the common names Sneed's pincushion cactus and carpet foxtail cactus. It is native to the Chihuahuan Desert, where it occurs in scattered locations in New Mexico, Texas, and Chihuahua. Some plants occurring in Arizona may be included within this species. Botanical authors do not necessarily agree on the circumscription of this species. Most will agree at this point in the research, however, that there are two varieties of "Escobaria sneedii", and that both are rare and endangered. The plant is popular with cactus enthusiasts and dealers because of its often petite size and tolerance for moderately cold climates. They have been overharvested from their natural habitat, the main reason why the two varieties, var. "sneedii" and var. "leei", have been federally listed as endangered and threatened, respectively.
Document 5: 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.
Document 6: Mammillaria: The genus Mammillaria is one of the largest in the cactus family (Cactaceae), with currently 200 known species and varieties recognized. Most of the mammillarias are native to Mexico, but some come from the southwest United States, the Caribbean, Colombia, Venezuela, Guatemala and Honduras. The common name "pincushion cactus" refers to this and the closely related genus "Escobaria".
Document 7: Strombocactus: Strombocactus disciformis is a rare species of cacti and the only species of the genus Strombocactus. The plant originates from Central and Northeast Mexico.
Document 8: Cypripedium montanum: Cypripedium montanum is a member of the orchid genus "Cypripedium".

This latter is also the common name of "Cypripedium acaule".
Document 9: Cypripedium: Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe (one species), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids or lady's slipper orchids; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "Cyp." The word ""Cypripedium"" is derived from the Late Latin: "Cypris", from Ancient Greek: Κυπρις  "(Kypris)" , an early reference in Greek myth to Aphrodite, and Greek: "pedilon", meaning "sandal".
Document 10: Schlumbergera microsphaerica: Schlumbergera microsphaerica is a species of plant in the Cactaceae family. It is endemic to a limited area of the coastal mountains of south-eastern Brazil where its natural habitat is rocky areas above 2600 m . It is threatened by habitat loss. It is in the same genus as the popular house plant known as Christmas Cactus or Thanksgiving Cactus.
Document 11: Cypripedium calceolus: Cypripedium calceolus is a lady's-slipper orchid, and the type species of the genus "Cypripedium".
Document 12: Opuntia atrispina: Opuntia atrispina is a cactus species in the "Opuntia" genus. It has limited distribution in the United States. In Texas it can be found from near Uvalde to Del Rio/Langtry--a small strip of area just 50 miles long.

Document 14: Schlumbergera: Schlumbergera is a small genus of cacti with six species found in the coastal mountains of south-eastern Brazil. Plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of "Schlumbergera" have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. In Brazil, the genus is referred to as "Flor de Maio " (May flower), reflecting the period in which they flower in the Southern Hemisphere.
Document 15: Escobaria: Escobaria, pincushion cactus or foxtail cactus is a genus of low-growing cacti that range from the southernmost parts of central and western Canada through northern Mexico, with one species in Cuba. The genus comprises about 23 species. The term "pincushion cactus" may also refer to the related "Mammillaria".
