Question: Are Calotropis and Mesquite both types of genera?
Sentence (from "Zygnemataceae"): The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, "Mougeotia", "Spirogyra", and "Zygnema" are by far the most common; in one study across North America, 95% of the Zygnemataceae collected were in these three genera.
Relevant evidence: No
