Abstract Background Floral adaptations supposedly help pollen grains to cross the numerous barriers faced during their journey stigmas. Stamen dimorphism and specialized petals, like cucculus in Cassieae tribe (Fabaceae), are commonly observed flowers that offer only as a resource for bee pollinators. Here, we experimentally investigated whether stamen enhance placement on bee’s body. Methods We used 3-D-printed models apply artificial vibrations of Chamaechrista latistipula with deflected or maintained its original position anther pores manipulated. After each simulated flower visit, captured photographs from four distinct angles. Employing digital imaging techniques, documented presence location stigma Key Results Our findings reveal redistributes There is remarkable increase density (~10-fold) lateral side adjacent cucculus, precisely where contacts when unmanipulated. Furthermore, also enhances ventral region bee, indicating additional function. The increases accuracy body, irrespective released by small large anthers. Conclusions traits, such modified petals dimorphism, can modify fate ultimately contribute male reproductive performance poricidal exhibits dual role promoting optimal regions pollination probably supporting feeding. These provide valuable insights into adaptive significance floral traits impact success flowers.
