title: Data from: Local adaptation: mechanical fit between floral ecotypes of Nerine humilis (Amaryllidaceae) and pollinator communities

description: Geographic variation in floral morphology is often assumed to reflect
 geographic variation in pollinator communities and associated divergence
 in selective pressures. We studied populations of Nerine humilis
 (Amaryllidaceae) to assess whether geographic variation in floral form is
 the result of local adaptation to different pollinator communities. We
 first tested for associations between floral traits and visitor
 communities, and found that populations with similar floral morphologies
 were visited by similar insect communities. Mean style length in each
 population was also closely associated with the mean body length of the
 local visitor community. A reciprocal translocation experiment
 demonstrated that native phenotypes set more seed than translocated
 phenotypes. Single visitation experiments showed that native flowers
 received more pollen, and set more seed per visit, than introduced
 phenotypes in both populations. This suggests that the effectiveness of
 pollinator visits is determined by the degree of mechanical fit between
 flowers and visitors. We provide strong evidence that the observed
 among-population variation in floral traits is an adaptive response to
 geographic variation in the pollinator community.
