Which plant has more species, Caralluma or Eucomis?
Caralluma Caralluma is a genus of flowering plants in the dogbane family, Apocynaceae, consisting of about 120 species.
Xerocomellus Xerocomellus is a genus of fungi in the family Boletaceae. The genus, as it was described in 2008, contained 12 species. However "X. rubellus" and "X. engelii" were transferred to the new genus "Hortiboletus" and "X. armeniacus" was transferred to the new genus "Rheubarbariboletus" in 2015. Molecular analysis supports the distinction of "Xerocomellus" species from "Boletus" and "Xerocomus", within which these species were formerly contained. "Xerocomellus" in fact is only distantly related to "Xerocomus" and is most closely related to "Tylopilus", "Boletus" sensu stricto, "Porphyrellus", "Strobilomyces", and "Xanthoconium".
