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

Context paragraphs:
Myosotidium: Myosotidium is a genus of plants belonging to the family Boraginaceae.  This genus is represented by the single species Myosotidium hortensia, the giant forget-me-not or Chatham Islands forget-me-not, which is endemic to the Chatham Islands, New Zealand.  The biogeography is yet unresolved, but its ancestors are likely from the American continent, as "Myosotidium hortensia" was found to be sister to the South American plant genus "Selkirkia" and both genera being sister to the North American genus "Mimophytum".

Leptospermum: Leptospermum is a genus of shrubs and small trees in the myrtle family Myrtaceae commonly known as tea trees, although this name is sometimes also used for some species of "Melaleuca".  Most species are endemic to Australia, with the greatest diversity in the south of the continent but some are native to other parts of the world, including New Zealand and Southeast Asia.  Leptospermums all have five conspicuous petals and five groups of stamens which alternate with the petals.  There is a single style in the centre of the flower and the fruit is a woody capsule.  The first formal description of a leptospermum was published in 1776 by the German botanists Johann Reinhold Forster and his son Johann Georg Adam Forster, but an unambiguous definition of individual species in the genus was not achieved until 1979.  Leptospermums grow in a wide range of habitats but are most commonly found in moist, low-nutrient soils.  They have important uses in horticulture, in the production of honey and in floristry.

Bartramia (plant): Bartramia is a genus of mosses in the family Bartramiaceae.  The genus was first formally described by Johann Hedwig in 1801.  There are about 72 species, usually growing on soil, sometimes on rocks, in many habitats in many parts of the world, although tropical species are only found at high altitudes.  Nine species occur in Australia but only three of these are endemic to that continent.

Antifer: Antifer is an extinct genus of large herbivorous deer of the family Cervidae, endemic to South America during the Pleistocene, living from 2.6 Ma-13,000 years ago and existing for approximately .  Cervids first entered the formerly isolated continent of South America during the Pliocene as part of the Great American Biotic Interchange.

Michauxia: Michauxia is a genus of plants in the Campanulaceae.  It contains 7 known species native to southwestern Asia.

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.

Owenia (plant): Owenia is a genus of plants, mainly trees in the mahogany family Meliaceae.  They are endemic to Australia and fairly widespread across the continent.  There are five species in the genus, most from New South Wales and living in conditions ranging from wet rainforest to the verges of the desert.  Like many plants, it plays its part in patch dynamics.

Exochaenium: The genus Exochaenium (22 species) is endemic to sub-Saharan Africa, with species occurring in most tropical and sub-tropical regions of the continent, particularly on the Katanga plateau (Angola, Democratic Republic of Congo and Zambia), with many extending to the Sudano-Zambesian and Guineo-Congolian regions.  The genus is monophyletic and is used to study the variation and evolution of herkogamy.

Calamoecia: Calamoecia is a genus of copepods in the family Centropagidae confined to Australasia.  It is thought to have evolved since the separation of the Australian continent from Antarctica.  Three of the Australian endemic species are listed as vulnerable species on the IUCN Red List (marked VU in the list below).  The genus contains the following species:

Hydrocynus: Hydrocynus is a genus of large characin fish in the family Alestidae commonly called "tigerfish," endemic to the African continent.  The genus name is derived from Ancient Greek ὕδωρ ("water") + κύων ("dog").  (In fact, this fish is popularly referred to as "poisson chien" (dog fish) in French-speaking West Africa.)  The genus contains five species, all popularly known as "African Tigerfish" for their fierce predatory behavior and other characteristics that make them excellent game fish.  "Hydrocynus" are normally "piscivorous" but "H. vittatus" is the only freshwater fish proven to prey on birds in flight.
