A recent study by Wu et al. and published in AoBP investigates the influence of spatial and inter-morph variation in pollinator-mediated selection of floral traits in the heterostylous species Primula secundiflora. Pollinator-mediated selection was estimated through female function in L-morph (long-style and short-anther phenotype) and S-morph (short-style and long-anther phenotype) flowers among four Primula secundiflora populations with different pollinator assemblages. Results indicated that a wider corolla tube width was selected in bumblebee-dominated populations, whilst shorter corolla tube length and wider corolla tube width were selected in the syrphid fly-dominated populations. Morph-specific variation in pollinator-mediated selection on corolla tube length was also detected in the syrphid fly-dominated populations. These findings highlight the potential forces of different pollinator agents in driving floral evolution in this primrose species and support previous studies demonstrating pollinator-driven diversification of floral traits.
