Question: Are both Genus Michauxia and Strombocactus endemic to the same continent ?

full_context: Document 1: 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 2: 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 3: 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 4: Mutisia: Mutisia is a genus of flowering plant in the mutisia tribe within the sunflower family. "Mutisia" has been named after José Celestino Mutis.

Document 8: 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 9: 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.

In the past, about 150 species were placed in this genus, most of which have since been assigned to other genera, the majority to genus "Erythranthe". "Mimulus
