Arum flower pollen trap

Référence de la vidéo 11936865
Track down the inside of the pollen trap of an Arum italicum flower head. The trap comprises a central spike called a spadix enclosed by a leaf-like spathe. The top of the flower emits a scent that attracts insects. These head downwards past the dense ring of hairs, which point downwards and prevent insects leaving again. Just below the hairs are the male flowers, which cover the insects in pollen. Below those is a smaller ring of hairs, above the female flowers. After a few days, the upper ring of hairs drops away, allowing the pollen-covered insects to leave and pollinate other flowers. For more views of this, see clips K004 2247-2252.
