Field studies in South Africa showed that floral spur length in the Disa draconis complex (Orchidaceae) varies enormously between populations in the southern mountains (means = 32–38 mm), lowland sandplain (mean = 48 mm), and northern mountains (means = 57–72 mm). We tested the hypothesis that divergence in spur length has resulted from selection exerted through pollinator proboscis length. Short‐spurred plants in several southern mountain populations, as well as long‐spurred plants in one… Expand
