Question: Are both Genus Michauxia and Strombocactus endemic to the same continent ?
Sentence (from "Myosotidium"): 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".
Relevant evidence: No
