DOI: 10.1093/molbev/msx318
Abstract: Abstract Immense floral trait variation has likely arisen as an adaptation to attract pollinators. Different pollinator syndromes—suites of floral traits that attract specific pollinator functional groups—are repeatedly observed across closely related taxa or divergent populations.… read more here.
