These are the anthers of a lily, cleverly done so that when the unsuspecting insect lands on it, the anther flips up and whops it on the back with a great load of pollen that it then goes to another plant with.
Ovu su prašnici ljiljana, pametno napravljeni tako kada insekt koji ništa ne sumnja na njih sleti, prašnik se izdigne i lupi ga po leđima s velikom količinom peluda s kojom onda on ide do druge biljke.
