Evolution of nectar spur length in a clade of Linaria reflects changes in cell division rather than in cell expansion

Abstract Background and Aims Nectar spurs (tubular outgrowths of a floral organ which contain, or give the appearance of containing, nectar) are hypothesized to be a ‘key innovation’ which can lead to rapid speciation within a lineage, because they are involved in pollinator specificity. Despite the...
