Abstract

A new natural hybrid, Sphagneticola × guangdongensis (Asteraceae, Heliantheae), is described and illustrated. Its chromosome number was revealed to be 2n = 53, lending strong support for its hybridity and parental origin (S. calendulacea with 2n = 50 and S. trilobata with 2n = 56) as previously already confirmed by evidence from morphology and molecular data.
